Abstract
The invention discloses a retainer for a rolling needle bearing, comprising a window hole (2) and window beams (1). The window hole (2) is used for placing rolling needles; guide bosses (3) are symmetrically arranged on adjacent window beams (1) in the window hole (2); the guide bosses (3) are arranged at two ends of the window beams (1); locking needle bosses (4) are arranged beside the guide bosses (3) along the radial direction of the retainer, and the locking needle bosses (4) protrude out of the guide bosses (3); the guide bosses (3) are arranged at the contact parts of the retainer and the guide rolling needles when in operation; and only two contact points are utilized on the axial direction of the window hole (2) to contact with the guide bosses (3), and the distance between two contact points is larger, therefore, the guidance of the retainer for the rolling needle cannot be influenced by uneven window holes (2).
Description
Technical field
The present invention relates to a kind of retainer, particularly a kind of needle bearing retainer.
Background technique
Needle bearing be a kind of can bear big radial force be applied to the bearing of compact occasion of structure, what general needle bearing adopted is the retainer of ferrous material, noise was bigger when his main shortcoming was work, and working process is also complicated.
Along with the application of engineering plastics is more and more wider, properties of materials (particularly having added the engineering plastics of the glass fibre of different proportion) has obtained the development of leap, in retainer, used wider, but because engineering plastics are the process of a heating-cooling in course of working, material can not reach desirable technical requirements after the heating cooling, particularly at the position of guiding needle roller because the wayward guiding function to needle roller of size is not enough, cause the performance deficiency of bearing.Therefore, to remedy the problems referred to above be necessary for structure reasonable in design.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can be to the better a kind of needle bearing retainer of guiding of needle roller.
In order to solve above-mentioned technical problem, technological scheme of the present invention is: a kind of needle bearing retainer comprises the fenestra and the window beam that are used to place needle roller, in fenestra, be provided with guide boss on the adjacent windows beam symmetrically, described guide boss is distributed in the two ends of window beam; Along retainer in the radial direction, described guide boss limit is provided with the purl boss, and described purl boss is given prominence to guide boss.
Along retainer in the radial direction, the both sides of described guide boss are provided with the purl boss.
Guide boss is the contacting point of retainer guiding needle roller when work, because the axial direction at fenestra only contacts (promptly contacting with guide boss) with two points, and the distance of two point of contact is bigger, so can be not good to the needle roller guiding because the retainer fenestra is uneven to the guiding of retainer.
The purl boss is arranged on the guide boss limit, and its outstanding guide boss can guarantee that needle roller can not drop out retainer.
The retainer of structure of the present invention has eradicated original retainer because the bearing in guiding not good needle bearing when work of causing walks to enclose phenomenon.
Description of drawings
Accompanying drawing is the structural representation of needle bearing of the present invention with retainer.
Embodiment
As shown in drawings, a kind of needle bearing retainer comprises the fenestra 2 and the window beam 1 that are used to place needle roller, in fenestra 2, is provided with guide boss 3 on the adjacent windows beam 1 symmetrically, and described guide boss 3 is distributed in the two ends of window beam 1.
Along retainer in the radial direction, described guide boss 3 limits are provided with purl boss 4, described purl boss 4 outstanding guide boss 3.
Guide boss 3 is contacting points of retainer guiding needle roller when work, because the axial direction at fenestra 2 only contacts (promptly contacting with guide boss 3) with two points, and the distance of two point of contact is bigger, so can be not uneven and not good to the needle roller guiding because of retainer fenestra 2 to the guiding of retainer.
Purl boss 4 is arranged on guide boss 3 limits, and its outstanding guide boss 3 can guarantee that needle roller can not drop out retainer.
Along retainer in the radial direction, the both sides of described guide boss 3 are provided with purl boss 4.
The retainer material of structure of the present invention is engineering plastics, and noise is bigger when having solved work, and working process is also than complicated problems.
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 (2)
1. needle bearing retainer, comprise the fenestra (2) and the window beam (1) that are used to place needle roller, it is characterized in that: in fenestra (2), be provided with guide boss (3) on the adjacent windows beam (1) symmetrically, described guide boss (3) is distributed in the two ends of window beam (1); Along retainer in the radial direction, described guide boss (3) limit is provided with purl boss (4), and described purl boss (4) is given prominence to guide boss (3).
