Factors to consider when choosing grease for robot bearings

Robot bearings are generally in the joints when they are used. The joints need to run at high speed and flexibility, so the requirements for the bearings will be higher, and the requirements for the operating conditions will be more stringent. If you want to run faster And flexible, in addition to ensuring the quality of the bearing, the use of grease is also very important.

 

   1. Robot bearing operating temperature

 

  Temperature has a great influence on the grease. If the environment and the operating temperature of the robot bearing are high, high-temperature-resistant grease should be selected for better operation.

 

  2, the rotation speed of the robot bearing

 

  High-speed running bearings have a high and rapid temperature rise, which is easy to make the grease thin and lose. In this case, a thicker grease should be used.

  3, the load of the robot bearing

 

Since the penetration of the grease is related to the load that it can withstand during use, the grease with a small penetration (larger consistency) should be selected for the heavy load; if it is subjected to both heavy load and impact load, it should be selected containing extreme Pressure additive grease, such as grease containing molybdenum disulfide.

 

  4, the use environment of the robot bearing

 

   is selected according to the different bearing working environment. In a humid environment, use a grease with strong water resistance; in a dusty environment, use a thick graphite-containing grease; in an acidic environment, use a base grease; if there are special requirements for sealing, Barium-based grease should be used.

 

   5. Rust of robot bearings

 

  The grease used in the robot bearing must have an anti-rust effect, and the anti-rust agent cannot dissolve in water. Grease should have good adhesion and can form an oil film on the surface of the steel to prevent rust.
