As can be seen here, above-mentioned existing angular contact ball bearing, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.The angular contact ball bearing of greasing can be repeated in the outer ring of therefore how to found a kind of new structure, and also becoming the current industry utmost point needs improved target.
Because the defect that above-mentioned existing angular contact ball bearing exists, the inventor is based on being engaged in this type of product specification manufacture abundant practical experience and professional knowledge for many years, and the utilization of cooperation scientific principle, positive research and innovation in addition, to founding a kind of outer ring of new structure, can repeat the angular contact ball bearing of greasing, can improve general existing angular contact ball bearing, 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
The purpose of this utility model is, overcome the defect that existing angular contact ball bearing exists, and the angular contact ball bearing of greasing can be repeated in the outer ring that a kind of new structure is provided, technical problem to be solved is to be to overcome existing High-speed Grease-lubricated angular contact ball bearing and expire because of Grease's lifetime, lubrication failure and the defect that causes bearing to be scrapped, in bearing outer ring design, repeat greasing structure, solve existing grease lubrication angular contact ball bearing and cannot repeat the defect of greasing, thereby reached the object that new structure bearing improves working life greatly.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of outer ring the utility model proposes, can repeat the angular contact ball bearing of greasing, comprising: outer ring, inner ring, rolling element, retainer, the first seal ring, the second seal ring, grease storage groove, greasing hole; Wherein: in the raceway groove in the middle of described inner ring and outer ring, be equiped with rolling element; In the raceway groove in the middle of described inner ring and outer ring, be provided with retainer, centre is provided with ball-type pocket hole and is connected with rolling element; Described the first seal ring, the second seal ring, be arranged in the middle of outer ring, inner ring and retainer both sides.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
The angular contact ball bearing of greasing can be repeated in aforesaid outer ring, it is characterized in that inner ring is provided with raceway groove.
The angular contact ball bearing of greasing can be repeated in aforesaid outer ring, it is characterized in that outer ring is provided with raceway groove.The angular contact ball bearing of greasing can be repeated in aforesaid outer ring, it is characterized in that being provided with depot fat ditch and in outer ring, being radially provided with greasing hole at place, medial sulcus road, outer ring.
The angular contact ball bearing of greasing can be repeated in aforesaid outer ring, it is characterized in that rolling element is ball-type, is arranged in retainer pocket hole.
The utility model compared with prior art has obvious advantage and beneficial effect.As known from the above, for achieving the above object, the utility model provides a kind of outer ring can repeat the angular contact ball bearing of greasing, comprising: outer ring, inner ring, rolling element, retainer, the first seal ring, the second seal ring, grease storage groove, greasing hole; Wherein: in the raceway groove in the middle of described inner ring and outer ring, be equiped with rolling element; In the raceway groove in the middle of described inner ring and outer ring, be provided with retainer and on retainer, be provided with ball-type pocket hole and be connected with rolling element; Described the first seal ring, the second seal ring, be arranged in the middle of outer ring, inner ring and retainer both sides.Technical characterstic of the present utility model: this kind of existing bearing structure of product and correlation technique only improve to some extent on disposable greasing amount, cannot solve the problem that bearing lost efficacy and scraps because of lubricating grease thoroughly.It is greasing hole, grease storage groove that the utility model can repeat greasing structure by outer ring design, coordinates the corresponding construction of main shaft producer in bearing support, has thoroughly solved prior art an open question.
By technique scheme, the angular contact ball bearing that greasing can be repeated in the utility model outer ring at least has following advantages and beneficial effect: the utility model can repeat greasing structure (greasing hole by outer ring design, depot fat ditch) coordinate the corresponding construction of main shaft producer in bearing support, solve existing grease lubrication double-direction thrust ball bearing and cannot repeat the defect of greasing, thereby reached the object that new structure bearing improves working life greatly.
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.
