Title: Dust cover structure for grease lubrication type pulley
Inventor: TANAKA TSUTOMU
IPC: F16H57/035
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To inject the adequate quantity of grease constantly, by arranging a dust cover close to a bearing, cantileveredly supporting the sealing member of an elastic body on the bearing, and providing an opening part for communicating with an outside air side and the bearing inside, onto the periphery of the dust cover on which the flexible side end part of the sealing member abuts. SOLUTION: Grease is injected from a grease nipple to be led into the space part 29 of a ball bearing 14 from the injection hole of a shaft to fill the space part 29. Filling the space part 29 with the grease rotates a sealing member 24 by being pushed by the grease, to contact a flexible side end part 31 the plate part 6 of the dust cover 1. The more injection of the grease into the space part 29 in this condition makes excess grease overflow outside from a fine gap between, the flexible end part 31 of the sealing member 24 and the arcwise surface 33 of an inner race 19, and moreover escape to an outside air side from the through hole 2 of the dust cover 1, thereby preventing filling the space part 29 inside of the ball bearing 14 with the excess grease.

The reflected light supplied from the substrate 2 focuses an image on a diffraction grating 10, passing through a window 4 and a light detecting element 9, and photoelectrically transferred by a light detector 11. A controller 12 turns on/off the excitation light source 5, and turns the light detecting element 9. The light supplied from the light source 6 among the outputs of the light detector 11 is taken into the device 12 through a DC amplifier 14, and when the ellipticity and the major axis direction reach the respective target values, vapor deposition is suspended. Further, the device 12 takes in only the excitation light synchronized with the turning-on/off through a lock-in amplifier 16, and temperature is controlled so that the variation of the reflectance reaches a target value.
