Is it better to decelerate the gears of the open rubber mixer or planetary deceleration

The planet is good, Kunshan Rongxing Power Transmission is a popular product of semi-drive permanent magnet motor applied in the internal mixer, helping customers save 30% of energy. You can take a look:

The half-drive permanent magnet motor is an integrated drive device composed of a medium-speed permanent magnet motor and a planetary reducer, with an output speed of n 200rpm and an output torque t=. It can widely replace the traditional low-speed and high-torque drive device of "asynchronous motor + fluid coupling + gearbox". This research and development is mainly aimed at the development status of our country, and energy conservation and emission reduction are the direction of every enterprise development.

Features: High operational efficiency.

It is estimated that under the same load and working system, the use of semi-drive permanent magnet motor can save about 30% of the power loss compared with the traditional asynchronous motor drive system.

Lightweight. Under the same working conditions, the volume and weight of the semi-drive permanent magnet motor can be reduced by more than 20%-50% compared with the full direct drive permanent magnet motor; Compared to conventional drive systems, the volume and weight can be reduced by more than 50%.

Intelligent control system.

The half-drive permanent magnet motor drive system is equipped with a "special control system", which can carry out smooth starting, speed regulation, intelligent operation and high reliability. The controller can provide access to CAN, RS485, Profbus DP and other communication interfaces, which can communicate with the host computer, realize the centralized control and operation of multiple devices, and transmit the operation data to the ground dispatching room for monitoring.

The traditional drive system (asynchronous motor + gearbox) uses power frequency electricity to start directly, with large starting current and single control function, which is not convenient for the intelligent development of the system.

The load starts. When the semi-drive permanent magnet motor starts, the current gradually increases with the load, and there is no large current impulse and the efficiency can be maintained at a very high level. In order to ensure the starting ability of the equipment, it is usually necessary to select an asynchronous motor with a larger power supply capacity or install a hydraulic coupling to realize heavy-load starting.

Product Applications. High-efficiency and energy-saving half-drive permanent magnet motors are widely used in metallurgical mining, lifting and transportation, petrochemical industry, wind power generation, cement industry, building materials industry, railway vehicles, port ships, textile printing and dyeing, casting, municipal engineering, paper printing, pharmaceutical, welding and other general equipment.

Good planet! I do reducers.

What you are talking about, I can roughly think so, to put it succinctly, copper sleeve is also called oil-containing copper sleeve or self-lubricating copper sleeve, generally copper sleeve is similar to a sleeve, there is no inner and outer ring, there are many black spots on the copper pipe, in fact, that is graphite, when lubricating, graphite will be used as a lubricant to lubricate. Generally, the speed is not high, but the radial load is too large, and the copper sleeve is used. The bearing is composed of an outer ring, an inner ring, a cage and rolling elements, and the structure is relatively complex.

Generally, it is a small range of circular motion or sheet motion. You can stoggle the shaft, if it's easy, it's the bearing, and if it's heavy, it's the copper sleeve. Or look at the drawing, or look at the size of the housing, the length of the copper sleeve will be a little longer than the bearing.

Hope, thank you!

General reducers include helical gear reducers (including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, etc.), planetary gear reducers, cycloidal pinwheel reducers, worm gear reducers, planetary friction mechanical continuously variable speed reducers, etc. The common types of reducers are worm gear reducers, the main feature is that it has a reverse self-locking function, which can have a large reduction ratio, and the input shaft and output shaft are not on the same axis or on the same plane. However, the general volume is large, the transmission efficiency is not high, and the accuracy is not high.

Harmonic reducer, its harmonic transmission is the use of flexible elements controllable elastic deformation to transmit motion and power, the volume is not large, the precision is very high, but the disadvantage is that the flexible wheel has a limited life, is not resistant to impact, and the rigidity is poor compared with metal parts. The input speed should not be too high. The advantages of the planetary reducer are that the structure is relatively compact, the return clearance is small, the accuracy is high, the service life is very long, and the rated output torque can be very large.

But slightly more expensive. Oral-Transmission is not only the first general reducer, but also the first planetary reducer, so the sales are more proficient in these two products, and there is no need to worry about problems such as difficulty in selection.

The difference starts with the merits.

First, the planetary reducer is small in size, easy to install, and can cope with most occasions Second, the planetary reducer has little noise (depending on the process), and will not produce large working noise.

As for the ordinary reducer, I don't know much about it, so I won't talk about it, and the planetary reducer is probably a little bit like that.

In addition, I am a professional reducer.

Characteristics of planetary reducer: an internal gear ring is tightly bonded to the gear box housing, there is a sun gear driven by external power in the center of the ring gear, and between the two there is a group of planetary gear sets composed of three gears combined in equal parts on the pallet, which is dependent on the output shaft, internal gear ring and sun tooth support to float in the period; When the power of the planetary reducer drives the sun gear on the input side, it can drive the planetary gear to rotate, and follow the trajectory of the inner gear ring to rotate along the center, and the rotation of the star drives the output shaft connected to the pallet to output power.

The torque of the planetary reducer with the same speed ratio is generally larger! It is suitable for frequent forward and reverse rotation, and the accuracy is also very good! Low noise Generally used in precision machinery!

The advantage of planetary reducer is that the structure is relatively compact and the accuracy is high. But it's more expensive.

The general reducer can be divided into four types: parallel shaft type, coaxial type, bevel gear-helical gear, and worm gear type. Generally, the volume is relatively small, and it is cheaper than the planetary reducer.

The reducer is generally used for low-speed and high-torque transmission equipment to put the motor. The power of the internal combustion engine or other high-speed operation is achieved by meshing the large gear on the output shaft with a small number of teeth on the input shaft of the reducer, and the ordinary reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect, and the ratio of the number of teeth of the large and small gears is the transmission ratio.

Characteristics of planetary cycloid deceleration: high-speed ratio and high-efficiency single-stage transmission, you can achieve a reduction ratio of 1:87, and the efficiency is above 90, if multi-stage transmission is adopted, the reduction ratio is greater.

Compact structure and small sizeDue to the planetary transmission principle, the input shaft and output shaft are on the same axis, so that the size of the model is as small as possible. Smooth operation, low noise, cycloidal needle teeth, large number of meshing teeth, large overlap coefficient and mechanism of mechanical balance, so that vibration and sound are limited to a minimum. Reliable use and long service life because the main parts are made of high-carbon chromium steel, quenched (HRC58 62) to obtain high strength, and part of the transmission contact adopts rolling friction, so it is durable and has a long life.

1. Advantages of planetary gear reducer and high-power series reducer: 1. Planetary gear reducer and high-power series reducer have small size, small mass, compact structure and large carrying capacity. Generally, under the same load conditions, the overall size and mass of planetary gear transmission are about 1 2 1 5 of ordinary gear transmission.

2. The transmission efficiency of planetary gear reducer and high-power series reducer is high. Due to the symmetry of the planetary gear transmission structure, the reaction force acting on the center wheel and the swivel bearing can balance each other, so as to help improve the transmission efficiency. Generally, its efficiency value can be reached.

3. The dynamic ratio of the planetary gear reducer and the high-power series reducer is large, and the transmission ratio can reach several thousand in the planetary gear transmission that is only used as a transmission motion. Moreover, when the planetary gear transmission has a large transmission ratio, it can still maintain many advantages such as compact structure, small mass and small size. 4. The planetary gear reducer and high-power series reducer have stable movement and strong ability to resist shock and vibration.

Because several planetary wheels with the same structure are used, they are evenly distributed around the central wheel, so that the force of the planetary wheel and the rotating arm can be balanced. At the same time, it also increases the number of teeth involved in meshing, so the movement of planetary gear transmission is stable, the ability to resist shock and vibration is strong, and the work is more reliable. Second, the disadvantages of planetary gear reducer and high-power series reducer are:

1. The required materials of planetary gear reducer and high-power series reducer are of high quality; 2. The structure of planetary gear reducer and high-power series reducer is complex; 3. It is difficult to manufacture and install planetary gear reducers and high-power series reducers.

The pendulum pin has strong impact capacity, disadvantages and high noise, and the planetary gear reducer has high efficiency and low noise.

The most important feature of the planetary reducer is high precision, small size, large bearing torque, the planetary reducer produced by Shenzhen Zhuochuang Transmission is divided into spur planetary reducer and helical planetary reducer, the whole series are double support structure, the planetary performance of the double support structure is stable, the rigidity is stronger, because there are support points on both sides of the gear, its bearing and planet carrier are integrated, each pin hole must correspond up and down, can not have a little deviation, and many planetary reducers on the market are single support structure, Because only one side of the gear has a support point, you only need to punch holes in the corresponding three corners at will, even if you make a mistake and change it to a 30-degree angle to re-punch, so the single-support reducer is cheap. Because it basically does not have the situation of scrapping, the double-supported servo reducer is different, as long as it deviates a little bit, it will be scrapped. The whole series of Shenzhen Zhuochuang Transmission is a planetary reducer with a double support structure, and its accuracy and concentricity are the best.

You can learn about Shenzhen Zhuochuang Transmission, which is a planetary reducer with a double support structure, with a spur servo reducer and a helical servo reducer. I have used them, the appearance and performance can be compared with Taiwan's wide use, their 115-10 reducer accuracy can be within 3 arc minutes, I used a lever with a diameter of 480mm to test, and the result is 18 wires, converted into angle units is in 3 arc minutes, you can understand.

Shanghai Huxing reducer factory is a professional R & D and manufacturing planetary reducer manufacturers!

It has the characteristics of low backlash (5-8arcmin), low noise (60dab), high efficiency (>=95%), high precision, high rigidity, high load, high speed ratio, high life, low inertia, low vibration, low temperature rise, beautiful appearance, light and small structure, easy installation, accurate positioning and so on. It is suitable for the speed increase and deceleration transmission of AC servo motor, DC servo motor, stepper motor and hydraulic motor. It is suitable for the connection of drive products manufactured by any manufacturer in the world

The gear reducer uses all levels of gear transmission to achieve the purpose of speed reduction. The reducer is composed of gear pairs at all levels. For example, the use of the pinion to drive the large gear can achieve a certain purpose of deceleration, and then the use of multi-stage such a structure, you can greatly reduce the speed.

The planetary reducer is composed of multi-stage gears, and the planetary gears cannot meet the larger transmission ratio, and sometimes 2 or 3 sets are needed to meet the requirements of the user's larger transmission ratio. Due to the increase in the number of planetary gears, the length of the 2nd or 3rd stage reducer will increase and the efficiency will decrease.

Zhaowei electromechanical planetary reducer features:

1. The miniature precision planetary gear reducer adopts modular design, which can be changed and combined according to customer requirements, 2. The reducer adopts involute planetary gear transmission, which makes reasonable use of internal and external meshing and power shunt, 3. The box body adopts ductile iron, which greatly improves the rigidity and seismic resistance of the box, 4. The gears are carburized and quenched to obtain a high hard and wear-resistant surface, and the gears are all ground after heat treatment, which reduces the noise and improves the efficiency and service life of the whole machine.

5. Small precision planetary reducers are divided into ZWBPD series, ZWPD series, ZWBMD series and ZWMD series, and the planetary transmission stages are 2 and 3 stages.

So much so.

1. Ready, multi-variety, there are more than 50 involute planetary gear transmission series designs in the world; In addition, it has evolved a variety of types of planetary reducers, differentials and planetary transmissions.

2. The gears in the tooth surface and high-precision planetary transmission mechanism are widely treated with chemical heat treatment such as carburizing and nitriding. The manufacturing accuracy of gears is generally above level 6. Obviously, the use of hard tooth surfaces and high precision is conducive to further improving the load carrying capacity and making the gear size smaller.

3. The rotation speed and high-power planetary gear transmission mechanism has been widely used in high-speed transmission, such as in high-speed steam turbines, and its transmission power is also increasing.

4. Specifications and large torqueIn medium and low speed and heavy-duty transmission, the large-scale planetary gear transmission that transmits large torque has been greatly developed.

The disadvantages of planetary gear transmission are: high-quality materials, complex structure, and more difficult to manufacture and install. However, with the further in-depth understanding and mastery of planetary transmission technology and the introduction, digestion and absorption of foreign planetary transmission technology, the transmission structure and load sharing mode have been continuously improved, and the production process level has also been continuously improved.

Therefore, the problem of its manufacture and installation is no longer regarded as a difficult matter. Practice shows that in a factory with a medium level of technology, it is completely possible to manufacture a better planetary gear transmission reducer.
