What kind of bearings can make industrial robots have higher precision?
For industrial robots , accuracy is a very important factor that directly affects product quality and productivity. The main factor affecting the accuracy of industrial robots is the bearings. So what kind of bearings can make industrial robots have higher precision? 1. Design of key structural parameters Industrial robot bearings have the requirements of long life, high rigidity and low friction. Therefore, when designing industrial robots, not only the maximum rated dynamic load should be considered, but also the optimal value of each structural parameter should be carefully selected to improve the contact stress distribution of the bearing parts. Then it can reach the optimum contact state for the formation of the lubricating oil film and improve the service life of the bearing. 2. The raceway position The inner and outer rings of the contact ball bearing of the industrial robot adopt the integral structure, and the general sectional area is only 20% of the beari...
