Planetary reducer has been widely used in industry because of its high cost performance. In addition, the integration of planetary reducer and servo motor has the advantages of modularization and serialization. Selection of planetary gear reducer components

1. Selection of bearings: in order to reduce the friction resistance moment between the shaft and the box during the operation of the planetary reducer, we need to use bearings on the shaft. As the output shaft and the input shaft are transmission shafts, the main loads are radial loads, so the bearings selected are deep groove ball bearings. The outer ring with a stop groove can simplify the axial positioning and reduce the axial size. It is equipped with dust-proof cover and seal, and the dust-proof cover and seal have good sealing and dust-proof performance. A certain amount of grease has not been put into the bearing, and no lubricating oil will be added for a long period of time during the working process.

2. Selection of key: when selecting the key, it is necessary to consider the magnitude of the working torque transmitted by the shaft, whether the moving direction of the parts on the shaft can require the key to be fixed in the axial direction of the parts on the shaft, the position of the key in the axial direction, the shaft diameter at the shaft connection and the design length of the hub. The key is a standard part, and the connecting member is a common B-type (flat head) key.

3. Design of the box: the box is one of the important parts of the planetary reducer, which is used to support and fix the shaft parts to ensure the lubrication and internal and external sealing of the rotating parts. In the design of the box, the general requirements are the premise of meeting the strength and rigidity. At the same time, the compactness of the structure and the convenience of manufacturing and installation shall also be considered. The method with clear weight requirements shall be adopted for the design. The material of the box is gray cast iron

4. Lubrication mode: the lubrication mode of planetary reducer directly affects the service life, efficiency and working performance of rotating parts. Therefore, lubricating oil or grease must be used for the lubrication of bearings and gears.

The above is an introduction to the design of the planetary reducer parts box. If you need planetary reducer, you are welcome to consult the Newgear manufacturer.
