Abstract
The invention discloses a high-speed bidirectional thrust angular contact bearing and relates to the technical field of bearing design. The high-speed bidirectional thrust angular contact bearing comprises a seat ring (1), shaft rings (2), retainers (3) and rolling bodies (4), wherein the shaft rings (2) are two same structures; the two shaft rings (2) are arranged side by side and are correspondingly arranged; the seat ring (1) is arranged outside the two shaft rings (2); the rolling bodies (4) are respectively arranged in rollaway nests between the seat ring (1) and the two shaft rings (2); the two retainers (3) uniformly isolate the rolling bodies (4) respectively. According to the high-speed bidirectional thrust angular contact bearing, the arrangement of space rings is eliminated, so that the mechanical processing amount is effectively reduced; furthermore, the high-speed bidirectional thrust angular contact bearing is simple in structure and convenient to operate.
Description
Technical field
The present invention relates to design bearing technical field, especially relate to a kind of high-speed bidirectional angular contact thrust ball bearing.
Background technique
Known, bidirectional angular contact thrust ball bearing can bear the connected load of radial and axial load simultaneously, axial displacement on the both direction of restrictive axes, along with machine tool chief axis high speed, the development of high-accuracy technology, to the rotating speed of spring bearing, require also more and more higher, at present, the fixed end that can bear bidirectional load supports and conventionally adopts bidirectional angular contact thrust ball bearing, this bearing is by a seat ring, two blowout patches, a spacer ring, two metal cages and rolling element form, structure is comparatively complicated, and the course of working of metal cage is loaded down with trivial details, revise comparatively difficulty, bearing noise after trap is also larger, rotating speed is also lower.
Summary of the invention
In order to realize described goal of the invention, the invention discloses a kind of high-speed bidirectional thrust angular contact bearing, described high-speed bidirectional thrust angular contact bearing is comprised of seat ring 1, two blowout patches 2, two retainers 3 and rolling element 4; The present invention, owing to having reduced the setting of spacer ring, has effectively reduced machining amount, and simple in structure, easy to operate.
In order to realize the object solving the problems of the technologies described above, the present invention has adopted following technological scheme:
A kind of high-speed bidirectional thrust angular contact bearing, comprise seat ring, blowout patche, retainer and rolling element, described blowout patche is two same structures, two blowout patche settings arranged side by side and corresponding, outside at two blowout patches is provided with seat ring, described rolling element is separately positioned in the raceway between seat ring and two blowout patches, and two retainers are separated rolling element respectively uniformly.
Described high-speed bidirectional thrust angular contact bearing, the material of described retainer is engineering plastics.
By adopting technique scheme, the present invention has following beneficial effect:
High-speed bidirectional thrust angular contact bearing of the present invention is comprised of seat ring 1, two blowout patches 2, two retainers 3 and rolling element 4; The present invention, owing to having reduced the setting of spacer ring, has effectively reduced machining amount, has reduced the noise of bearing, and simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In the drawings: 1, seat ring; 2, blowout patche; 3, retainer; 4, rolling element.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described, so that those skilled in the art further understands the present invention, but following embodiment is not limiting the scope of the present invention.
Fast bidirectional propulsion angular contact bearing described in 1 by reference to the accompanying drawings, comprise seat ring 1, blowout patche 2, retainer 3 and rolling element 4, described blowout patche 2 is two same structures, two blowout patche 2 settings arranged side by side and corresponding, in the outside of two blowout patches 2, be provided with seat ring 1, described rolling element 4 is separately positioned in the raceway between seat ring 1 and two blowout patches 2, and two retainers 3 are separated rolling element 4 respectively uniformly, and the material of described retainer 3 is engineering plastics.
Implement high-speed bidirectional thrust angular contact bearing of the present invention, when mounted, rolling element 4 is packed in the engineering plastics cage 3 with lock ball function, described retainer 3 is formed by mold injection on injection machine, and then carry out trap with seat ring 1, blowout patche 2, gap and the pretension of the height-adjustable bearing by reconditioning blowout patche 2, not only reduced the noise of bearing, also improved the rotating speed of bearing; The present invention, owing to having reduced the setting of spacer ring, has effectively reduced machining amount, and simple in structure, easy to operate.
Part not in the detailed description of the invention is prior art.
The embodiment who selects in this article in order to disclose goal of the invention of the present invention, currently thinks suitablely, still, will be appreciated that, the present invention is intended to comprise that all belong to all changes and the improvement of the embodiment in this design and invention scope.
