Abstract
The utility model relates to a kind of retainer roller thrust bearing of improvement, comprise: seat ring, blowout patche, cylinder rolling element and retainer, wherein, this retainer is arranged between seat ring and blowout patche, this retainer is welded by upper retainer and lower retainer, upper retainer and lower retainer are dome-shaped, are respectively equipped with the square hole distributing along even circumferential on upper retainer and lower retainer end face, and cylinder rolling element is arranged in the square hole of retainer and lower retainer.Under comparable size condition, retainer of the present utility model fills rolling element quantity to be increased, and the bearing capacity of bearing increases, and rolling element running is more steady, is widely used in that radially installation dimension is limited, the occasion that the limit speed of bearing is had relatively high expectations.
Description
Technical field
The utility model relates to a kind of roller thrust bearing, particularly relates to a kind of retainer roller thrust bearing of improvement.
Background technique
Existing roller thrust bearing, generally comprises seat ring, blowout patche, cylinder rolling element and retainer, and seat ring and blowout patche are loose rib, and retainer is entity retainer, on the external diameter of retainer, is provided with pocket hole along circumference.Because existing entity retainer is to establish pocket hole on the external diameter of retainer, cylinder rolling element circumferential arrangement, between adjacent column rolling element, there is beam to separate, so under equal radial dimension condition, bearing effectively carries cylinder rolling element limited amount, the occasion that load is had relatively high expectations, bearing load carrying capacity does not reach requirement.
Because the problem that above-mentioned existing roller thrust bearing exists, practical experience and the professional knowledge of the inventor based on being engaged in this type of product specification manufacture and enriching for many years, and the utilization of cooperation scientific principle, actively research and innovation in addition, to founding a kind of retainer roller thrust bearing of improvement, can solve the problem that existing roller thrust bearing exists, make it have more practicability.Through constantly research, design, and after repeatedly studying sample and improving, finally create the utility model having practical value.
Summary of the invention
Main purpose of the present utility model is, overcome a limited number of problems of existing roller thrust bearing carrying cylinder rolling element, and provide a kind of retainer roller thrust bearing of improvement, technical problem to be solved is the bearing capacity that can carry more cylinder rolling element, increase bearing, is very suitable for practicality.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to the retainer roller thrust bearing of a kind of improvement the utility model proposes, comprise: seat ring 1, blowout patche 2, cylinder rolling element 3 and retainer 4, this retainer 4 is arranged between seat ring 1 and blowout patche 2, this retainer 4 is welded by upper retainer 41 and lower retainer 42, upper retainer 41 and lower retainer 42 are dome-shaped, on upper retainer 41 and lower retainer 42 end faces, be respectively equipped with the square hole 5 distributing along even circumferential, cylinder rolling element 3 is arranged in the square hole 5 of retainer 41 and lower retainer 42.
The utility model compared with prior art has obvious advantage and beneficial effect.By technique scheme, the retainer roller thrust bearing of the utility model improvement at least has following advantages and beneficial effect:
1, under comparable size condition, retainer of the present utility model fills rolling element quantity, and to fill rolling element quantity than traditional entity retainer many, the bearing capacity of bearing increases, rolling element running is more steady, be widely used in that radially installation dimension is limited, the occasion that the limit speed of bearing is had relatively high expectations.
2, retainer of the present utility model can also play certain sealing and dustproof effect, extends bearing working life.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, and for above and other object of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Embodiment
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to its structure of retainer roller thrust bearing, feature and effect thereof according to the improvement the utility model proposes, be described in detail as follows.
Referring to Fig. 1 is the schematic cross-section of the utility model preferred embodiment, Fig. 2 is the plan view of cylinder rolling element and retainer structure, the retainer roller thrust bearing of improvement comprises: seat ring 1, blowout patche 2, cylinder rolling element 3 and retainer 4, this retainer 4 is arranged between seat ring 1 and blowout patche 2, this retainer 4 is welded by upper retainer 41 and lower retainer 42, upper retainer 41 and lower retainer 42 are dome-shaped, on upper retainer 41 and lower retainer 42 end faces, be respectively equipped with the square hole 5 distributing along even circumferential, cylinder rolling element 3 is arranged in the square hole 5 of retainer 41 and lower retainer 42.Under comparable size condition, retainer of the present utility model fills rolling element quantity, and to fill rolling element quantity than traditional entity retainer many, can increase the bearing capacity of bearing.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
