How to prevent cross roller bearing slippage

Since crossed roller bearings slippage is a common bearing failure, when the crossed roller bearings work, the rollers must perform pure rolling motion on the inner and outer ring tracks. 90; font-family: Helvetica Neue, Helvetica, Arial, sans-serif; font-size: 14px; text-wrap: wrap; background-color: rgb(255, 255, 255);">

1. Prevent cross-rolling Measures for sub-bearing slippage

　1. Reduce the diameter of the roller

　2. Reduce the weight of the retainer

In addition to reducing the weight of the retainer while ensuring its strength, the resonance, high-speed rotation resistance and other characteristics must also be considered. If the unbalance of the retainer is properly controlled, changing the retainer from an external guide to a guide is also very beneficial in reducing sliding. Due to the external guide, the oil film will form a viscous resistance through the relative movement between the retainer and the bearing guide surface, but the inner guide is the opposite, and the viscous force of the oil film between the retainer and the guide surface will become a traction force. Therefore, the viscous resistance becomes a force that drags the retainer to rotate. The difference between the two cannot be ignored.

3. Use elliptical bearings

　　The use of elliptical bearings is a common anti-slip measure. The outer diameter of the outer ring of the bearing is generally elliptical, and the inner diameter of the outer ring (track) and the bearing seat are circular.

4. Fill in the ring

　　Changing the outer ring stop end to the inner ring stop end will definitely reduce the resistance to stirring.

2. Causes of cross roller bearing slippage

　　Some materials "keep up" and form pockmarks; many attached parts protrude from the original surface. In addition, there are abraded areas and non-abraded areas on the working surface, which is closely related to the alternating load and the degree of damage to the straps.

Three, the impact of cross roller bearing slippage

1. Working surface of worn bearings

　　Sliding in crossed roller bearings is likely to cause wear on the bearing working surfaces. For example, shaft vibration and alternating loads can generate forces that destroy the lubricating oil film, resulting in scratches on parts of the working surfaces of the rollers and inner ring raceways.

　　2、导致轴承卡死

　　如果交叉滚子轴承的滑动磨损严重，滚子和内圈之间会产生过大的摩擦热，导致内圈膨胀，径向的游隙变小，所以轴承会卡死。
