The structure and size 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 universal industrial reducer is not limited by the inner hole of the gear and the wall thickness of the tooth root part less than 2.5m1. The pinion and the shaft are more integrated, which can cancel the connection between the hole processing and the shaft and the hub, enhance its rigidity and prevent 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 by steps, and cannot be directly processed with round steel.
2. 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 use the 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 attention should be paid to the additional stress caused by anti-skid and interference
4. The cost of connecting the ring gear with planetary Liming reducer bolts is high, but it is reliable. When necessary, it can be designed and selected 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, only Select small processing production equipment for processing products, so this structure must be selected.
The reducer is an independent component enclosed in a rigid housing composed of a gear drive, a worm drive and a gear-worm drive. It is often used as a reduction drive between the drive part and the working machine. It is between the prime mover and the working machine or actuator. It plays the role of matching speed and transmitting torque, and is widely used in modern machinery.
