AI Technical Summary
Technical Problem
The installation efficiency of spacers in existing crossed roller bearings is low, which affects assembly efficiency.
Method used
A cubic or cuboid block-shaped isolation block is designed. The outer surface of the isolation block has two opposing and parallel contact surfaces. Each contact surface is provided with a cylindrical groove and an oil guide channel. The oil guide channel guides the lubricating oil through a guide plate and an elastic sheet to achieve efficient distribution of the lubricating oil.
Benefits of technology
This improves the installation efficiency of crossed roller bearings, reduces the motion resistance between the rollers and the spacers, and extends the service life of the bearings.
