What is the difference between a planetary reducer and a gear reducer? What are the pros and cons of

Planetary reducer is actually a kind of gear reducer if it is classified, and like most gear reducers, planetary reducer is to reduce the speed and increase the output torque through gear transmission. However, compared with ordinary gear reducers, the structure of planetary reducers is more compact and reasonable, and makes full use of all parts to work for deceleration transmission. Ordinary gear reducers are through the meshing of gears to reduce the speed, and the planetary reducer in addition to the meshing between gears, but also through a planetary structure, that is, the principle of planets rotating around the star, the star as the origin, that is, the motor of the planetary reducer enters the shaft gear, driving the planet, that is, the planetary gear in the planetary reducer, in the outermost, that is, the inside of the shell of the planetary reducer, there are also teeth to participate in the deceleration of the planetary reducer.

Such a structure, in addition to greatly improving the precision, can also add multiple identical gear combinations to the same planetary reducer to increase the speed ratio, and will not affect the structure and strength of the planetary reducer itself. Commonly used Risesco planetary reducer SCE, SCF, SCS, WPLF and other models.

Definition of reducer gear ratio:

The principle of reducer is generally used for transmission equipment with low speed and high torque, and to put the motor. The power of the internal combustion engine or other high-speed operation through the gear with a small number of teeth on the input shaft of the reducer meshes the large gear on the output shaft to achieve the purpose of deceleration, and the ordinary reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect, the ratio of the number of teeth of the large and small gears is the transmission ratio also known as the reduction ratio (abbreviation"Gear ratio"）

Gear reducer ratio: 5-1500;

Definition of reducer transmission ratio: The principle of reducer is generally used for transmission equipment with low speed and high torque, and the motor is used. The power of the internal combustion engine or other high-speed operation through the gear with a small number of teeth on the input shaft of the reducer meshes the large gear on the output shaft to achieve the purpose of deceleration, and the ordinary reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect, the ratio of the number of teeth of the large and small gears is the transmission ratio also known as the reduction ratio (abbreviation"Gear ratio"）

Transmission ratio calculation formula:

Reducer transmission ratio = motor output speed reducer output speed ("Gear ratio"Also called"Reduction ratio", abbreviation"Gear ratio")

Transmission ratioIn a mechanical transmission system, the ratio of the angular velocity or rotation speed of the starting driving wheel to the end driven wheel.

Transmission ratio (i) = the ratio of the speed of the driving wheel (n1) to the speed of the driven wheel (n2) = the inverse ratio of the diameter of the gear indexing circle = the ratio of the number of teeth of the driven gear (z2) to the number of teeth of the driving gear (z1). i.e.: i=n1 n2=d2 d1 i=n1 n2=z2 z1

For multi-stage gearing 1: The transmission ratio between each two shafts is calculated according to the above formula.

2: The total transmission ratio from the first shaft to the nth axis is calculated according to the following formula: Total transmission ratio = (z2 z1) (z4 z3) (z6 z5) ......n1/n2）×（n3/n4）×(n5/n6)

The planetary gear reducer generally has a single-stage speed ratio, and the two-stage speed ratio is any combination of any two single-stage speed ratios. Guangzhou Bapman planetary reducer with low backlash, low noise and low temperature rise is a good choice.

Planetary reducer.

The advantages are mainly as follows:

1) In terms of structural appearance, the volume is pure and small, and the structure is relatively compact and lightweight.

2) In terms of transmission, the reducer runs smoothly, has no noise, has strong bearing capacity, and can withstand strong impacts; Gear ratio

The wide range and the ability to achieve multi-stage deceleration are precisely the characteristics of the robotic arm.

It has been widely used; High transmission efficiency.

3) In terms of use, the Buckman planetary reducer has a longer service life than the ordinary reducer.

Compared with the efficiency of harmonic reducer and RV reducer 70 85, the efficiency is high, which can reach more than 95%, and the price and leakage grid are relatively low compared to the chain of Zaihu; Compared with ordinary multi-stage gear transmission, the speed ratio is higher under the same volume; High precision and small backlash.

Abstract:Planetary gear reducer, also known as planetary gear reducer, is a kind of gear reducer, but different from ordinary gear reducer, it uses planetary gear, and has certain differences from ordinary gear reducer in terms of structure, use, performance, etc. Compared with the planetary reducer and the gear reducer, it is not necessarily better, mainly according to the needs and application fields to choose the right reducer.

Let's take a look at the difference between planetary reducer and scrambled silver gear reducer. 1. Is the planetary reducer a gear reducer?

There are many types of reducer, according to the transmission type can be divided into gear reducer, worm reducer and planetary reducer, planetary reducer is actually a kind of gear reducer, its full name is planetary gear reducer, the use of planetary gear to achieve the deceleration effect, its principle and gear reducer is the same, but there are some differences in structure, use and other aspects.

2. What is the difference between planetary reducer and gear reducer?

Planetary reducer is a gear reducer, but it is different from ordinary gear reducer, and the main differences are:

1. The difference between the number of structural returns.

The main transmission structure of the planetary reducer is planetary gear, sun gear and internal gear ring; The gear reducer is a combination of a geared motor and a large reducer, including a prime mover group and a working unit gear.

2. Difference in use.

As a supporting component, the planetary reducer is mainly used in lifting, excavation, transportation, construction and other industries; Gear reducers are widely used in large-scale mines, steel, chemical industry, ports, environmental protection and other fields.

3. Performance differences.

Compared with ordinary gear reducers, planetary reducers have larger transmission ratios and higher precision.

3. Which is better, planetary reducer or gear reducer?

Planetary reducer and gear reducer are both reducer devices, which is better is not necessarily, mainly depends on the demand and application field:

1. The accuracy of the planetary reducer is relatively high, and the range of deceleration is also relatively wide, which is more suitable for use in metallurgy, mining, lifting and transportation, electric power, energy, building materials, light industry, transportation and other industrial fields.

2. The advantage of gear reducer is that it has a compact structure, good overload capacity, and large power, which is more suitable for application in three-dimensional parking lot equipment, automatic storage, three-dimensional warehouse, chemical industry, construction, transportation, energy, mining, lifting, wharf and other fields.

It will be determined when it leaves the factory! If you forget, turn the shaft and see how many turns.

1. The planetary reducer is composed of a solar gear system and a group of live multiple groups of planetary gears (one group is three), which can maintain a fairly high accuracy in the process of telling the operation, and the volume of the planetary reducer is very small relative to its output torque.

A single section can do 1 10, through the modular design, the speed ratio can reach 1000, or even more than 1000.

However, because of its material accuracy and meticulous processing methods, the cost of planetary reducer is much higher than that of gear reducer.

2. Gear reducer, a single section can be done 1 200, and a higher speed ratio of 1 2000 can be achieved through modular installation, this kind of reducer runs smoothly, the noise is very small, and the market price is low, and it is mostly used for various low-load assembly line installations.

Compared with the planet, the gear reducer cannot improve the accuracy at all, and the torque is even less likely to reach the height of the planet.

The main structure of the planetary reducer is the planetary gear, which uses the planetary gear to achieve the effect of power distribution and multi-tooth meshing. The planetary reducer has the characteristics of high rigidity, high precision (single-stage can be achieved within 1 minute), high transmission efficiency (single-stage is 97%-98%), high torque, small size, and lifelong maintenance-free. Because of these characteristics, most planetary reducers are installed on stepper motors and servo motors to reduce speed, increase torque, and match inertia.

Compared with the planetary reducer, the accuracy and transmission efficiency of the gear reducer are low, and its accuracy is much lower than that of the planetary reducer.

This is due to the different forms of the gear transmission mechanisms used:

Planetary gear reducer is the use of planetary gear set, its characteristics are mainly: coaxial, large reduction ratio, complex manufacturing.

Gear reducers are the most commonly used gears that use ordinary spur or helical gears.

The planetary reducer you are talking about is the simple name of the planetary gear reducer.

Planetary gear reducer includes, gear discs, gears (sun gear, planetary gear), planetary carriers and other structures, of course, there are sealing rings, oblique cylindrical bearings, etc., and its process is relatively complex, so its manufacturing cost is also higher! When it comes to its structure, it can still be divided into quite a variety. For example, there are right-angle outputs, linear outputs, housing rotation outputs, and more!

The responsibilities and functions of the reducer are simply to reduce the speed and increase the torque! This also includes the output direction, etc.!

When we were in school, we came into contact with the gearbox reducer, the principle of which is so simple that every student of the Department of Mechanics or anyone who has been in contact with the gearbox knows it. However, the principle of planetary gear reducer is the same, but its structure is different!

There is a difference in structure. More contact is.

Planetary reducer and planetary gear reducer are the same, planetary reducer has high torque, high rigidity, high precision output (high efficiency, low noise), and low backlash. With the characteristics of high positioning accuracy, it can be matched with servo motor and stepper motor to reduce speed, increase torque, and be high.

The gear reducer is characterized by small size, simple structure, low noise, high transmission efficiency, and disadvantages: low accuracy and transmission efficiency.
