Abstract

A dust cover for sealing the opening of the engagement element is disclosed. The dust cover is removable from the opening of the element by a tool. The dust cover includes a body and an elastic part. The body defines an outer perimeter, an inner surface, an outer surface, and a groove disposed along the outer surface. The groove is shaped to accept the shape of the tool portion. The resilient portion is located around the outer perimeter of the body. The resilient portion is sealingly engaged with the opening of the body element.

Description

technical field [0001] The present invention relates generally to dust covers that sealingly engage an opening of a pulley assembly, and more particularly to reusable dust covers. Background technique [0002] Pulleys such as drive pulleys (front and rear), idler pulleys, and tension pulleys are used in automobiles. More specifically, these pulleys can be used to drive or tension belts for drive systems. The belt drive system may include a drive pulley and one or more idler pulleys, and a continuous belt. The pulleys may each comprise a pulley housing or a body having a belt engaging surface. The continuous belt is designed to surround the belt engaging surface of each pulley shell. [0003] Each pulley may also include one or more bearings, which may be located within bores in the pulley housing. Sometimes nuisances such as, for example, dust, sand, salt or mud may enter the bearing. These nuisances increase wear and reduce the life of the bearing. Accordingly, a dust...
