What is a gear reduction motor? How does a geared motor work?

The following is arranged by Lingnan Automation, the gear reducer motor is in front of the output shaft of a vertical ordinary motor (single-phase or three-phase asynchronous motor), and a gear reducer is installed to constitute a gear reducer motor.

It is specially used for some mechanical and electrical equipment, such as marine, paper mills, garment factories, food processing plants, cranes, light and heavy machinery operations, etc.

It is a kind of mold, precision transmission product.

Hello: In the gearing of a gear motor, the gear ratio is determined by the distance between the center of the gear and the point of contact.

For example, in a device with two gears, if one gear is twice the diameter of the other gear, then the gear ratio is 2:1

The gears in modern gear motors use a special tooth profile called involute, which has the very important property of maintaining a constant speed ratio between the two gears.

On helical geared motors, the cutting direction of the gear teeth is at an angle to the gear surface. When two teeth on a helical gear system are engaged, the point of contact will start at one end of the teeth and gradually move to the other end as the gear rotates until the two teeth are fully engaged.

The geared motor is through this meshing method, the helical gear is smoother than the spur gear when running, and the noise is relatively small, so almost all automobile transmission gearboxes use helical gears. Since the teeth on a helical geared motor are angled, when they mesh, the gears will be subjected to a certain amount of pressure, and equipment that uses helical gears is equipped with bearings to withstand this pressure. Another very interesting feature of helical gears is that if the gear teeth are angled at the right angle, they can be loaded onto shafts perpendicular to each other, resulting in a meshing angle of 90 degrees.

The geared motor is generally an ordinary DC motor, but a gear reducer is added in front of the ordinary motor. 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.

Introduction to reducer motor: refers to the integration of reducer and motor (motor). This kind of integration can also be called a gear reducer motor or gear reducer motor, which is usually integrated and assembled by a professional reducer manufacturer and supplied as a complete set.

Geared motors are widely used in the steel industry, machinery industry, etc., and the advantages of the popular miniature geared motor in the 21st century are that the design is simplified and space-saving, while the power, reduction ratio, and torque are not reduced.

The biggest difference between the deceleration motor and the ordinary motor is that it will reduce the speed, the purpose is to decelerate and increase the torque, which is more conducive to the smooth start of the vehicle, the deceleration principle is to mechanically add a group of gears on the original basis, and realize the speed reduction of the final output of the starter with the principle of small wheel with large wheel.

I'll teach you how to discern:

No matter what reducer, it is connected to the motor, so the reducer is mostly composed of two parts:

1. The mounting flange connected to the motor, also called the mounting plate, is usually a hole (the motor shaft is inserted) and four positioning mounting holes (connected to the output end of the motor).

2. It is the output of the reducer, which is easy to understand, and it is no different from the output end of the motor.

There are many types of reducers: planetary reducers, worm gear reducers, planetary cycloid reducers, gear reducers and so on.

There are 2 types of planetary reducers: straight and right-angled.

The function of the reducer is simply put: reduce the speed, increase the torque, and match the inertia.

Hope mine can help you.

1. There is no reducer for the motor itself, and it is a reducer for the load of the motor.

2. The commonly used reducers are: 1) cylindrical gear transmission, with driving wheels, driven wheels, intermediate gears, etc.;

2) Star gear, depending on the diameter of the inner and outer gears to change the speed.

If you don't know what it looks like, just look at it**! However, different types of motors look different.

A gear motor is a hydraulic motor that injects a pressure fluid to rotate two (or more) gears meshing with each other in the pump casing. Gear motors have the characteristics of simple structure, small size, light weight, etc., and are generally used for high speed and low torque.

Gear hydraulic motor is referred to as gear motor, which has the characteristics of simple structure, small size, light weight, small inertia, impact resistance, convenient maintenance, and low requirements for oil filtration accuracy. However, its flow pulsation is large, the volumetric efficiency is low, the torque is small, and the low-speed performance is not good.

Gear motors can be divided into two types: one is a gear motor based on a gear pump; The other is a specially designed gear motor. The former is similar in structure to a gear pump, while the latter is due to some special requirements of the motor:

For example, the motor is often started with load, and the impact and vibration of the external load are more serious, and it must be able to rotate in both directions.

The structure of the gear motor and the gear pump is basically the same, but because the gear motor needs to be started with load, and it is required to be able to rotate in the forward and reverse directions, the gear motor is still different from the gear pump in terms of actual structure.

Due to the poor sealing and low volumetric efficiency of the gear motor, the input oil pressure can not be too high, the torque is generally not large, and its speed and torque are pulsating with the meshing of the gear. Therefore, gear hydraulic motors are generally used in the case of high speed and low torque.

The following points should be paid attention to during the use of gear hydraulic motors:

1) The installation between the output shaft of the gear hydraulic motor and the actuator adopts an elastic coupling, which is greater than the coaxiality error and the axiality error of the shaft sleeve coupling shall not be greater.

2) The back pressure of the oil drain port of the gear hydraulic motor shall not be greater than.

3) The working medium of gear hydraulic motor is recommended to use No. 46 hydraulic oil or other neutral mineral oil with kinematic viscosity.

When the compressed air enters the air chamber from the left air port, it sprays to the blade immediately, acts on the outer extension of the blade, generates torque to drive the rotor to rotate along the needle, outputs the mechanical energy of rotation, exhaust gas is discharged from the middle air port, and the residual gas is discharged from the right air port; If the left and right ports are reversed, the rotor reverses and outputs mechanical energy in opposite directions.

The centrifugal force of the rotor rotation, the air pressure at the bottom of the blade, and the spring force make the blade tightly against the inner wall of the air motor to ensure sealing and improve the volumetric efficiency.

For the purpose of reducing the speed of the air motor after reducing the gear and increasing the torque of the motor, the following example is 10:1 legend.

Gear reducer motor is also known as reducer and gearbox, and its main function is to reduce the output speed (speed ratio), improve torque and load capacity, and achieve the ideal transmission effect; Gear reducer motors are divided into low-power gear reducer motors and high-power reducer motors according to power, which are used in different occasions; For example, Zhaowei electromechanical low-power gear reducer motor is often used in the fields of automobile transmission, smart home and industrial automation.

Parameters of low-power gear reduction motor:

Diameter: 3mm-38mm

Voltage: 3V-24V

Power: Speed ratio: 2-2000

Material: plastic, metal gear.

That is, the output end of the motor is equipped with a gear reducer, so that the speed of the output shaft decreases and the output torque increases. It can meet the requirements of low speed and high torque under load conditions.

The large and small gears are used to occlude each other to realize the speed difference between the input and output terminals, so as to achieve the purpose of deceleration and satisfactory torque.

Whether it is a geared motor or a geared motor, there are usually many different classifications of faults. There are many different names for such as unstable voltage, incorrect installation of capacitors, failure of starter components, damage to gears, shafts, bearings, broken connecting wires, poor fixing, etc. However, its performance is usually divided into nine categories, and the following is a summary of various gear reducer motor failures:

1: Under the no-load state, the motor does not rotate.

The reasons are: improper voltage; The capacitor is connected incorrectly or is not connected; Poor operation of single-phase motor starter; Damage to gears, shafts, bearings, etc.;

2: When loaded, the motor does not rotate.

The cause of the failure may be that the motor or motor is running under overload, or the gear may be damaged;

Three: Abnormal fever.

The causes of this failure may be: overload; The voltage is too high or too low, the bearing is worn, etc.;

Four: The noise is too loud.

The causes of this failure are usually bearing damage and gear wear;

Five: unusually unstable operating noise;

The reasons for this situation are: the gear bearing is seriously worn or the motor is not well fixed, and the flange screw is loose;

Six: The vibration is too great.

When the vibration is too large, of course, you need to check whether the footing or the mounting screws on the flange are fixed first. Other possible reasons are: insufficient oil quantity, oil pollution, etc.;

Seven: brake failure.

The reasons for such failures usually are: the clearance is too large or too small, commonly known as brake failure;

Eight: oil leakage. Oil leakage usually leads to a quick exhaustion of oil in the equipment, resulting in a series of problems such as heat generation and gear damage;

Nine: the coil is damaged.

The causes of this problem are usually complex, such as voltage or current, as well as coil damage if the capacitor is not well installed or water is ingress.

Gear reducer motor is used in all walks of life to provide corresponding power and speed for these mechanical equipment, and its main role is four words: deceleration and force increase. There are three types of gear reduction motors: small gear reduction motors, medium gear reduction motors, and large gear reduction motors, all of which are composed of gear reducers and motors.

Common medium-sized gear motors are usually rated in the between, i.e. between 1 10hp and 5hp horsepower. It is divided into single-phase (110 220V (and three-phase (220V 380V), both of which can be installed on the output of the gear reducer motor.

Shaft bending: If the shaft is found to be running out of the terminal has the phenomenon of jumping, it means that the shaft is bending, and when the shaft bending is serious, the phenomenon of friction between the stator and the rotor will occur, and the rotor should be taken out and corrected according to the specific situation after the shaft is bent.

2. The core of the shaft is worn: due to the long-term operation of the motor, the iron loose gear and the core of the shaft will sometimes be loose, and the shaft has not been rolled over. In this case, knurling in the mating section should be considered.

If there is a possibility of displacement of the lower core on the shaft, an annular groove should be opened on the shaft at both ends, and then two arc keys should be put in, and welded together with the shaft.

3. Shaft diameter wear: the bearing is dismantled many times, which will make the shaft diameter wear, and it can generally be knurled at the diameter. If the wear is severe, a layer can also be stacked at the shaft diameter, and then processed with a lathe and the size is required.

4. Shaft cracks: If the transverse cracks of the shaft do not exceed 10 15% of the diameter and the longitudinal cracks do not exceed 10% of the shaft length, they can be repaired by electric welding and continue to be used. If the shaft is severely damaged or broken, a new shaft must be replaced.

Non-rotating, physical operation, idling, toothing and poor suction, etc. Poor contact,
