AI Technical Summary

Technical Problem

Existing cam-type clutches suffer from insufficient lubrication and poor sealing performance under high load, high frequency start-stop, or dusty environments, leading to bearing overheating, accelerated wear, and increased maintenance workload, thus increasing operating costs.

Method used

A cam-type clutch with a sealed lubrication structure was designed. It uses components such as an oil tank, oil seal, and sealing gasket to form a closed lubrication system to prevent lubricating oil leakage. The oil level is detected by a dipstick to enhance sealing performance and connection strength.

Benefits of technology

It effectively prevents lubricating oil leakage, extends clutch service life, reduces friction, improves overall machine protection, reduces maintenance workload, and lowers operating costs.

Abstract

This utility model relates to the field of mechanical transmission technology, and in particular to a cam-type clutch with a sealed lubrication structure. The technical solution includes: an inner race, an outer race, a cam, a snap ring, a bearing, and an oil tank. The inner and outer races constitute the basic rotational support structure of the clutch. The cam is installed between the inner and outer races and is used to realize the clutch function. The bearing is located between the inner and outer races and is used to support the rotating components. A sprocket is provided on the outer wall of the outer race. The oil tank is located on the outer race, and the lubricating oil inside is used to lubricate the bearing. A sealing component is provided at the end of the inner race corresponding to the oil tank to prevent lubricating oil from entering the inner race. This utility model has the advantages of compact structure, good sealing and lubrication function, and easy installation and maintenance through the fit between the structures.
