Title:
SYNCHRONOUS FOLLOW-UP MECHANISM OF CAGE FOR ROLLING ELEMENT OF ROLLER BEARING CONDUCTING ROCKING MOTION
Document Type and Number:
Japanese Patent JPH01150021
Kind Code:
A
Abstract:
PURPOSE: To execute pure swivel motion without a slide or a creep by forming a pinion on two diametrically opposite sites with circular arc segment gears having different pitch circle diameters. CONSTITUTION: A roller body 2 rolls on an outer peripheral surface 5 of parts 6 forming an inside guidance track. A pinion 8 is rotatably engaged to a shaft pin 7 on an end surface of a bearing cage 4 retaining the roller body 2 within a pocket 3. The pinion 8 has circular arc segment gears 9, 10 having different pitch circle diameters on two diametrically opposite sites. Each of the segment gears 9, 10 is engaged to segment gears 11, 12 respectively connecting to an outer wheel element 1 or the bearing part 6. When the outer wheel element 1 is relatively moved against the bearing part 6, the roller body 2 is rotated on the guidance track. At this time the bearing cage 4 is moved from a starting position, so an accurate moving motion of the bearing cage 4 and an accurate rolling motion of the roller body 2 can be obtained.
