The structure and dimensions of the planetary Liming reducer will be described in detail later. Nowadays, there are fewer and fewer cast iron gears used in various reducers, and alloy steel forgings are widely used. The gear structure of the reducer has some new features.

1. The gear general industrial reducer is not restricted by the wall thickness of the inner hole of the gear and the tooth root part being less than 2.5m1. The pinion and the shaft are more integrated, and the connection between the hole processing and the shaft and the hub can be eliminated, which enhances its own rigidity and prevents product assembly And social gear accuracy drops.

When the diameter of the downshift shaft is less than 0.6 times the diameter of the crown dome, in order to prevent the core material from falling off significantly, the shaft diameter is forged with steps instead of round steel.

2. The solid wheel, in order to simplify the structure of the planetary Liming reducer, reduce the processing time and heat treatment deformation, right? For small and medium-sized gears below 700 mm, it is recommended to directly adopt a solid structure instead of thinning the spoke plate.

3. The interference ring gear is suitable for the situation where the ring gear data is difficult to weld, but the additional stress caused by anti-skid and interference should be paid attention to

4. The cost of connecting the gear ring with planetary Liming reducer bolts is high, but it is reliable. It can be designed and selected when necessary to prevent the stress caused by interference, the welding process is difficult, or the pressing equipment is less, and the experience is less. For enterprises, they can only choose small processing and production equipment for processing products, so they must choose this structure.

The reducer is an independent component enclosed in a rigid housing composed of gear transmission, worm transmission and gear-worm transmission. It is often used as a reduction transmission device between the driving part and the working machine. It plays a role in matching the speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.
