Title: Thermally plastic resin made bearing parts
Inventor: INABA HIDEYUKI
IPC: F16C33/20
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To provide bearing parts showing their excellent circularity and cylindricality by making a hollow molding without using any reamer work through provision a groove in a part for connecting a bearing part to a fixed part, providing reinforcing ribs for connecting the bearing part to the fixed part and providing a hollow part in the bearing part. SOLUTION: When the connection part between a bearing part and a fixed part is made a hollow part, the connection part between the bearing part and the fixed part is formed thin and the bearing part is apt to bend from its root. Normally, ribs are provided outside to prevent its fall but when no rib can be provided, grooves are provided in the parts for connecting the bearing parts on the side where no rib can be provided to the fixed parts, and by erecting a reinforcing rib for connecting the bearing part to the fixed part inside of the groove, the fall of the bearing part can be prevented. Thus, by forming a hollow part around the circumference of a shaft hole, the bearing parts can be restricted from deformation of the shaft hole caused by contraction of resin so as to hole excellent circularity and coaxiality, resulting in possibility of omitting reamer work.
