AI Technical Summary
When installing cylindrical rollers on the inner ring of a bearing, workers need to install each roller on the outer side of the inner ring one by one, which is cumbersome and results in low assembly efficiency.
A roller positioning device for full complement cylindrical roller bearings without outer rings is adopted, including a positioning body, a positioning stop, a clamping block, and a positioning clamping mechanism. The rollers are quickly installed on the inner ring of the bearing through the roller placement mechanism and the positioning clamping mechanism. The cooperation between the positioning stop and the clamping block ensures a stable connection.
The roller installation process has been simplified, assembly efficiency has been improved, and the quick installation of cylindrical rollers on the inner ring of the bearing has been achieved, avoiding individual operations and improving assembly efficiency.
