SCRAPER RING FOR CLEANING A HYDRAULIC CYLINDER ROD OR SHAFT

摘要

SCRAPER RING FOR CLEANING A HYDRAULIC CYLINDER ROD OR SHAFT Foreign material is removed from a shaft or rod of a hydraulic cylinder by a surrounding wiper or scraper ring formed in two semicircular mating sections. The sections have surfaces forming a shaft engaging scraping edge and also have axially spaced walls which define a circumferentially extending external groove. The ring sections are mounted on the rod or shaft and are coupled together or retained by a resilient spring wire having undulations which extend within the radial groove. Closely spaced opposite end portions of the retaining wire are curled to form eyelets and project laterally from the groove into an undercut recess which intersects the groove. The eyelets are adapted to receive the tips of a tool for releasably positioning the end portions of the retaining wire within the undercut recess.
