Abstract
The invention discloses a thrust bearing comprising an outer gasket (1), an inner gasket (2), a steel ball (3) and a retainer (5), wherein the outer gasket (1) is matched with a groove (4) of the inner gasket (2) to form a rollway of the steel ball; the steel ball (3) is arranged in the rollway and is fixed by the retainer; and the outer gasket (1) has not mutual contact with the inner gasket (2). The thrust bearing disclosed by the invention has simple and compact structure; and with the arc groove (4) formed by stamping the outer gasket (1) and the inner gasket (2) on the inner side, the steel ball can flexibly and reliably roll in the groove and the requirement for an opening device of a spinning machine can be met.
Description
Technical field
The present invention relates to a kind of bearing, the bearing in particularly a kind of textile manufacturing machine shedding motion.
Background technique
The textile manufacturing machine shedding motion provides the power of loom shedding and the device of signal, each shedding motion has the multi-disc blade, and be connected to the shedding system by connecting rod, has only very little gap between the blade, blade can not grazing and relative movement is arranged, therefore, need a kind of compact bearing that bears axially loaded in this occasion.
Summary of the invention
Technical problem to be solved by this invention provides a kind of compact structure, can bear axially loaded and guarantee the thrust-bearing of bearing play.
In order to solve above-mentioned technical problem, technological scheme of the present invention is: a kind of thrust-bearing, it comprises outer washer, inner washer, steel ball and retainer, the inboard of described outer washer, inner washer is respectively arranged with annular groove, the groove fit of outer washer, inner washer constitutes the raceway of steel ball, steel ball is arranged in the raceway and by retainer and fixes, and described outer washer does not contact mutually with inner washer.
The outer rim of described outer washer and inner washer is all to in-flanges, and inner washer is positioned at outer washer inside.
In order to reduce the friction that the steel ball motion produces, the ratio of curvature steel ball size of described groove is big.
The invention has the beneficial effects as follows: thrust bearing of the present invention is simple, compact, at the arc groove that the inboard punching press of outer washer and inner washer is made, makes and the steel ball flexibility and reliability of rolling satisfies the requirement of textile manufacturing machine shedding motion inside.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
As shown in drawings, a kind of thrust-bearing, it comprises outer washer 1, inner washer 2, steel ball 3 and retainer 5, outer washer 1 and inner washer 2 are to adopt the iron plate punching press to make.The inboard of outer washer 1, inner washer 2 is respectively arranged with annular groove 4, and in order to reduce the friction that steel ball 3 motion produces, ratio of curvature steel ball 3 diameters of described groove 4 are big, makes steel ball 3 flexibility and reliability of rolling to satisfy the requirement of textile manufacturing machine shedding motion inside.
The groove 4 of outer washer 1, inner washer 2 cooperates the raceway that constitutes steel ball 3, and steel ball 3 is arranged in the raceway also fixing by retainer 5, makes outer washer 1 and inner washer 2 can realize relative movement.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
Claims (3)
1. thrust-bearing, it is characterized in that comprising outer washer (1), inner washer (2), steel ball (3) and retainer (5), the inboard of described outer washer (1), inner washer (2) is respectively arranged with annular groove (4), the groove (4) of outer washer (1), inner washer (2) cooperates the raceway that constitutes steel ball, steel ball (3) is arranged in the raceway and by retainer and fixes, and described outer washer (1) does not contact mutually with inner washer (2).
2. thrust-bearing according to claim 1 is characterized in that: the outer rim of described outer washer (1) and inner washer (2) is all to in-flanges, and inner washer (2) is positioned at outer washer (1) inside.
