What factors should be considered when selecting grease for robot bearings?
March 18, 2023
When robot bearings are used, we are generally at the joints. The joints need high speed and flexibility, so they will have higher requirements for bearings. At the same time, the requirements for social operation will be more strict. In order to run fast and flexible, in addition to ensuring the quality management of bearings, the use of lubricating grease is also very important, What factors should be considered for the grease used in robot bearings? Today, we will discuss the factors that need to be considered when selecting robot bearing grease, and we will study them together.
1. Operating temperature of robot bearing Temperature has a great influence on lubricating grease. If the environment and mechanical operation temperature are high, high-temperature resistant lubricating grease should be selected. 2. Rotation speed of robot bearing The temperature rise of high-speed running parts is high and fast, which is easy to make the lubricating grease thin and lose, so the lubricating grease with higher consistency should be selected. 3. Load of robot bearing Because the permeability of grease is related to the load it can bear when it is used, the grease with low permeability (high consistency) should be selected to bear the larger load, and the grease with extreme pressure additives, such as molybdenum disulfide, should be used.
This is all the factors that should be considered when selecting grease for robot bearings. In addition, the type and size of robot bearings, working conditions, vibration and whether the direction of the main shaft is horizontal or vertical, as well as cooling conditions are all related. It can be seen from the above that suitable lubricating grease should be selected according to different conditions during bearing operation to ensure normal operation.
