Knowledge of worm gear reducer

Worm gear reducer is a kind of power transmission mechanism, which uses the speed converter of gear to reduce the rotation number of motor to the required rotation number and obtain a large torque. Among the mechanisms used to transmit power and motion, reducer is widely used.

The basic structure of worm gear reducer is mainly composed of transmission parts, worm gear, shaft, bearing, box and its accessories. It can be divided into three basic structural parts: box, worm gear and worm, bearing and shaft combination. The box is the base of all accessories in the worm gear reducer. It is an important accessory to support and fix the shafting components, ensure the correct relative position of the transmission accessories and support the load acting on the reducer. The worm gear is mainly used to transmit the motion and power between the two staggered shafts, and the bearing and shaft are mainly used to transmit power, operate and improve efficiency.

Some accessories of worm gear reducer are explained as follows:

Oil cover / breather, mainly used to exhaust the gas in the case of worm gear reducer;

The end cover is divided into large end cover and small end cover. The end cover is used to fix the axial position of shafting components and bear axial load. Both ends of bearing seat hole are closed with bearing cover;

Oil seal; It is mainly used to prevent the leakage of lubricating oil inside the chassis and improve the service time of lubricating oil;

The oil drain plug is mainly used for draining dirty oil and cleaning oil when replacing lubricating oil;

The oil standard cover is mainly used to observe whether the oil inside the case of the worm gear reducer meets the standard;

The main functions of worm reducer are:
1. Reduce the speed and increase the output torque at the same time. The torque output ratio shall be multiplied by the motor output by the reduction ratio, but pay attention not to exceed the rated torque of the reducer.
2. Deceleration also reduces the inertia of the load, which is the square of the reduction ratio. You can see that general motors have an inertia value.
