Geared motor is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. There are many types of geared motors, and different types of geared motors have different uses. Geared motors can be divided into geared motors, worm geared motors and planetary geared motors according to the type of transmission. Geared motors can be divided into single-stage and multi-stage geared motors according to the number of transmission stages, and according to the shape of the gear on the geared motor. Geared motors can be divided into cylindrical geared motors, bevel geared motors and bevel-geared geared motors; and according to the transmission arrangement of the geared motors, they can be divided into expanded geared motors, shunt geared motors and coaxial geared motors. Wait.

The main feature of the turbo worm gear motor is that it has a reverse self-locking function and can have a large reduction ratio. The biggest feature of the turbine worm gear motor is that the input shaft and the output shaft are not on the same axis and are not on the same plane. However, the turbine worm gear motor is generally relatively large, and the transmission efficiency is not high and the accuracy is not high.

的 The harmonic transmission of the harmonic geared motor uses the controllable elastic deformation of the flexible element to transfer motion and power. Harmonic geared motors are small in size and high in accuracy, but the disadvantages are that the flexible wheel has a limited life, is not resistant to impact, has relatively poor rigidity and metal parts, and the input speed cannot be too high. The advantages of planetary geared motors are not only compact structure, or small clearance, high accuracy, long service life, and large rated output torque. But planetary geared motors are more expensive than other geared motors.

There are four main reasons for the oil leakage of the geared motor. These four reasons are: the pressure difference between the inside and outside of the geared motor, the irrational structural design of the geared motor itself, the excessive amount of oil in the geared motor, and the geared motor. Improper maintenance process.

During the operation of the geared motor, the friction of the running pair and the influence of the ambient temperature increase the temperature of the geared motor. If the ventilation holes are blocked or there are no ventilation holes, the pressure in the geared motor will gradually increase, and the temperature inside the machine will be higher. The larger the pressure difference with the outside world, the lubricant will leak out of the gap under the effect of the pressure difference.

The structural design of the geared motor is unreasonable. Not only is the structure unreasonable found in the materials, but also the reasons why the components of the geared motor are not completed during processing. The other is that the geared motor itself is not well sealed, or There is no oil return tank for the case without geared motor. During the operation of the geared motor, the oil pool will be agitated very much, and the lubricating oil will splash everywhere in the box. If the amount of oil is too much, a large amount of lubricating oil will accumulate on the shaft seal, the joint surface, etc., causing leakage. The improper maintenance process of the geared motor is mainly due to the incomplete removal of dirt on the joint surface or the failure to install some components properly when inspecting the equipment, which will also cause oil leakage.
