How to improve the service life of robot bearings

Robot bearing is an important part of mechanical equipment. If you want to improve the service life of robot bearing, it is necessary to select the size and accuracy according to the location of use, use conditions and environmental conditions. Matching suitable bearings is the premise to ensure the life and feasibility of robot bearings.

1. Parts of use: Robot bearings are suitable for bearing combined radial and axial loads mainly based on radial loads. They are usually used in pairs with two sets of bearings, mainly for front and rear wheel hubs, driving bevel gears, differentials, etc. of automobiles. Transmission parts such as reducer.

2. Allowable rotational speed: In the environment of correct installation and good lubrication, it is allowed to be 0.3-0.5 times the limited rotational speed of the robot bearing. Under normal circumstances, 0.2 times the speed limit is appropriate.

3. Allowable inclination angle: Robot bearings generally do not allow the shaft to be inclined relative to the housing hole. If there is an inclination, it should not exceed 2′.

4. Allowable temperature: Under normal load, and the lubricant has high temperature resistance and sufficient lubrication, the general bearing is allowed to work at an ambient temperature of -30°C to 150°C.
