Abstract

The utility provides a combined-type pillar retainer, belonging to the field of a bearing fitting. The pillar retainer is composed of an upper rib, a lower rib and a pillar. Both the upper rib and the lower rib are ring-shaped, clamp-connecting holes with the same quantity are distributed on the upper rib and the lower rib, and the pillar is respectively matched with the clamp-connecting holes of the upper rib and the lower rib by tenons at the two ends of the pillar; the innovative point of the pillar retainer lies in that the tenons at the two ends of the pillar are round or nearly round, working surfaces of the pillar are two straight surfaces, and an included angle of the two straight surfaces is an obtuse angle. Compared with the prior art, as the structure of the tenons is changed into round or nearly round shapes, the matching precision is improved; and the measuring data proves that the matching precision of the tenons with the upper rib and the lower rib is changed from 0.3mm into 0.1mm. As the matching of the tenons with the upper rib and the lower rib is more precise, the friction noise of the bearing retainer is greatly reduced when in use, thus enlarging the application field of the retainer and leading the retainer to be widely applied in mute environments; moreover, after the matching is more precise, heat produced due to friction is reduced, thus prolonging the service life of the retainer to some extent.

Description

A kind of combination post cage

(1) technical field

The utility model relates to a kind of Bearing fittings, specifically a kind of combination post cage.

(2) background technique

Its tenon of the combination post cage of prior art is square structure, reason owing to processing technology, the matching gap of tenon and last rib, following rib is bigger, its precision is about about 30, so matching gap makes the combination post cage of prior art only can be applied in some in the less demanding environment of noise, and this has just limited the application of combination post cage to a certain extent.

In addition, the combination post cage of prior art, its working surface are cambered surface, bearing roller cooperates with working surface can't form shoe cream room after closely knit, this just need open shoe cream room more separately in cambered surface, this just makes processing technology complicated to a certain extent, has increased the manufacturing cost.

(3) summary of the invention

Technical assignment of the present utility model is at the deficiencies in the prior art, provides that a kind of processing technology is simple, low cost of manufacture, quality of fit height, combination post cage that application is wide.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of combination post cage, comprise rib, following rib and pillar, last rib and following rib be structure ringwise all, be evenly equipped with the identical blocked hole of quantity on it, pillar cooperates with the blocked hole of last rib and following rib respectively by the tenon at its two ends, its innovative point is that the tenon at pillar two ends is rounded or near round structure, so-called is exactly to make the location more accurate near circle.

Combinations thereof formula post cage, the working surface of its pillar are two flat faces, and the angle of two flat faces is the obtuse angle.When bearing roller with after two flat faces cooperate, just surrounded a shoe cream room naturally by its three.

Combinations thereof formula post cage, the angle α of its two flat face is between 155 °-175 °.

Combination post cage of the present utility model compared with prior art, the beneficial effect that is produced is:

1) square structure with the pillar tenon makes circle into or near round structure, has improved quality of fit, and survey data proves that the quality of fit of tenon and last rib and following rib becomes 10 by 30.Because both cooperations are more accurate, make retainer in use, its friction noise reduces greatly, thereby enlarged the application of retainer, make its wider being applied in some quiet environment, in addition, cooperate more accurate after, it is reduced because of fricative heat, improved the working life of retainer to a certain extent.

2) square structure with the pillar tenon makes circle into or near round structure, has not only improved quality of fit, and makes simplified processing technology, has reduced the manufacturing cost.

3) working surface with pillar becomes angle two flat faces in obtuse angle by cambered surface, when bearing roller with after two flat faces cooperate, just surrounded a shoe cream room naturally by its three, and need not on original cambered surface, to process shoe cream room separately again, thereby make simplified processing technology, lowered the manufacturing cost.

(5) embodiment

Below in conjunction with explaining below 1-6 pairs of a kind of combination post cages works of the present utility model of accompanying drawing.

Shown in accompanying drawing 1-3, combination post cage of the present utility model, its structure comprises rib 1, following rib 2 and pillar 3, last rib 1 and following rib 2 be structure ringwise all, be evenly equipped with 16 identical blocked holes of quantity on it, pillar 3 cooperates with the blocked hole of last rib 1 and following rib 2 respectively by the tenon 4 at its two ends, and the tenon at pillar 3 two ends 4 is rounded or near round structure.

Shown in accompanying drawing 4-6, the working surface of pillar 3 is flat face 5 and flat face 6, and the angle of flat face 5 and flat face 6 is the obtuse angle, and angle α is between 155 °-175 °.

Its processing and fabricating of a kind of combination post cage of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.

Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
