Latest Patents

Elmer H. Doerr holds a patent for a "Combined bearing, rotatable member and shield assembly." This invention features a combined bearing, pulley, and shield assembly that is temporarily unitized prior to installation on a cylindrical shaft support. The design includes a bearing with inner and outer races, creating an annular space between them. This bearing is molded into the hub of the pulley, with a pair of shields that cover the annular space. The shields are attached to the pulley by frangible tabs that are molded integrally with the pulley. Upon installation, the shields are precisely positioned and fixed to the inner race. The tabs fracture in response to the initial relative rotation of the pulley and inner race, allowing for free subsequent relative rotation.
