Technological scheme according to the utility model: but the lubricated pull type clutch release bearing of a kind of greasing; Comprise release sleeve and be positioned at bearing outer ring, ball and the bearing inner race of said release sleeve one side; Between said bearing outer ring outside the said ball and said bearing inner race, be provided with seal ring; Be provided with supported spring between the end face of said bearing outer ring and said release sleeve; Be fixed with shell between the exterior edge face of said bearing outer ring and the outer wall of said release sleeve; The inner side end of said bearing outer ring and said bearing inner race is provided with annular groove, and the inner side end of said release sleeve is provided with the bulge loop with said annular groove Spielpassung, has the greasing hole that communicates with said annular groove on the said release sleeve.
Said annular groove is formed with the shaft shoulder that is arranged on the said bearing inner race inner side end by the pit that is arranged on the said bearing outer ring inner side end.
Have on the said bulge loop and axially lead the fat cylindrical hole, the said fat cylindrical hole of leading communicates with said greasing hole.
Said greasing hole is opened on the boss on the said release sleeve outer wall.
Said supported spring adopts the shape wave supported spring.
Be provided with the retainer of the said ball in location between said bearing outer ring and the said bearing inner race.
Said retainer is positioned at the both sides of said ball, and by closing-up together.
The outside excircle of said bearing inner race is provided with holddown spring.
Be provided with support ring between said holddown spring and the said seal ring.
Said holddown spring is the helicon spring.
The technique effect of the utility model is: the utility model release sleeve is provided with the greasing hole that communicates with release bearing inside; When release bearing when in use internal lubrication fat runs off because of high temperature failure; Can be in time through the greasing hole to the inner supplemental lubrication fat of release bearing; Keep the bearing good lubricating property, prolong the working life of release bearing.
