AI Technical Summary
Technical Problem
Poor sealing between the roller shaft and bearing of the cotton cleaning machine leads to fiber entanglement and overheating of the roller shaft, which in turn accelerates bearing wear.
Method used
A sealing mechanism was designed, including a groove, a support ball, a contact ring, a compensating spring, and a compensating gasket. The sealing connection between the end cap and the bearing housing is achieved through rolling contact and elastic support, preventing fibers from entering the bearing area.
Benefits of technology
It effectively prevents fiber entanglement, protects bearings, prevents shaft overheating, and extends equipment lifespan.

Abstract
This utility model relates to the field of cotton cleaning machine technology, specifically to a shaft end connection structure for a cotton cleaning machine beater shaft that prevents fiber entanglement and heat generation. It includes a mounting frame and a shaft disposed inside the mounting frame. Bearing seats are provided on the inner walls of the left and right sides of the mounting frame, and bearing grooves are formed inside the bearing seats. Bolt holes, a bushing, and a bearing are provided on the outer side of the shaft. A rubber gasket is provided on the inner side of the bushing. An end cap and connecting bolts are fixedly installed on the outer side of the bushing. A sealing mechanism is provided between the end cap and the bearing seat. By using this shaft end connection structure to prevent fiber entanglement and heat generation, the structural design of the sealing mechanism, combined with the compensating spring and compensating gasket, achieves a sealing contact between the compensating gasket and the annular groove, thereby sealing the can cover and bearing seat, effectively preventing fibers from entering the bearing area and facilitating bearing protection.
