Abstract
The utility model relates to a double-cover retainer of a thrust ball bearing, which mainly solves the service life problem of a thrust ball bearing. The utility model is characterized in that the utility model is composed of two standard retainers, wherein a rolling body is arranged in a pocket hole of an inner retainer and an outer retainer is jointed and riveted with the inner retainer. After the double-cover retainer is improved, the service life of the bearing is improved by 20 times. The utility model can be widely suitable for equipment, such as rolling machines, plastic machinery, oil presses, etc.
Description
Affiliated field
The utility model relates to a kind of retainer, specifically is the double-contracting retainer of thrust ball bearing.
Background technique
Present thrust ball bearing retainer all is single bag retainers, the bearing of this single bag retainer is in use owing to be in the high speed rotating, steel ball is owing to be subjected to action of centrifugal force that the retainer sealing part is had very big impact force, when single bag retainer can not withstand shocks power, retainer will opening, steel ball will spin off from retainer, makes bearing early failue.
Summary of the invention
The purpose of this utility model is the double-contracting retainer of long thrust ball bearing of a kind of life-span.
The technical solution of the utility model is: the double-contracting retainer of thrust ball bearing, it is characterized in that forming by the retainer of two standards, and rolling element places in the interior retainer pocket hole, outer retainer and the involutory riveted joint of interior retainer.
The beneficial effects of the utility model are: improve the back and adopt the double-contracting retainer, in high speed rotating, side, the contact force in the pocket hole of raceway groove increase though steel ball is pressed to, friction increases phenomenon and still exists, but the ability to bear that double-contracting keeps is than the height of single bag, make improve 20 times the working life of bearing, satisfied client's demand.Can be widely used on the equipment such as rolling mill, plastics machinery, oil press.
Description of drawings
Accompanying drawing is the double-contracting retainer longitudinal sectional view of thrust ball bearing.
Among the figure; Retainer, 3 outer retainers in 1 steel ball, 2.
Embodiment
The double-contracting retainer is through retrofiting, combining on the basis of single bag retainer.
As shown in the figure.The double-contracting retainer is a box type retainer, and this retainer is made up of interior retainer 2, the outer retainer 3 of two standards.Steel ball is put into the pocket hole of retainer 2, and the involutory back riveted joint of outer retainer and interior retainer forms.
Claims (1)
1, the double-contracting retainer of thrust ball bearing is characterized in that being made up of the retainer of two standards, and rolling element places in the interior retainer pocket hole, outer retainer and the involutory riveted joint of interior retainer.
