Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1-4, the utility model is a bearing needle roller retainer, which comprises a retainer body 1, an inner flange groove 2, an outer flange groove 3 and window holes 4, wherein a plurality of window holes 4 are formed on the side surface of the circumference of the retainer body 1 and used for containing needle rollers, the window holes 4 are communicated with the inner side and the outer side of the retainer body 1, the inner flange groove 2 is arranged at one end of the retainer body 1, and the outer flange groove 3 is arranged at the other end of the retainer body 1 and used for preventing the needle rollers from falling off; the retainer body 1 is inboard to be equipped with a plurality of tie-beam 5 along the circumferencial direction equipartition, and tie-beam 5 is connected with interior flange groove 2, and tie-beam 5 is connected with outer flange groove 3, and the both sides wall symmetry of tie-beam 5 sets up, and the lateral wall of tie-beam 5 includes first lateral wall 6 and second lateral wall 7, and first lateral wall 6 and second lateral wall 7 are the obtuse angle setting, form the accommodation space 8 that is used for installing the bearing kingpin between the adjacent tie-beam 5.
Furthermore, the minimum width of the accommodating space 8 is R1, and R1 is smaller than the diameter of the bearing needle roller, so that the needle roller can be prevented from falling off from the inner side of the accommodating space, and the stability of the bearing structure is further ensured.
Furthermore, the maximum width of the accommodating space 8 is R2, and R2 is more than or equal to 1.5 times of the diameter of the bearing needle roller, so that the needle roller is convenient to mount, the friction force between the needle roller and the accommodating space can be reduced, and the friction loss is reduced.
Specifically, the material of the retainer body 1 is high temperature resistant plastic, which not only can bear high temperature, but also can ensure that the retainer has sufficient strength.
The retainer body 1, the inner flange groove 2, the outer flange groove 3, the window hole 4 and the connecting beam 5 are integrally formed by injection molding, and processing is facilitated.
The working principle of the embodiment is as follows: firstly, the roller pins are arranged in the space, then grease is injected into the bearing through external equipment, part of the grease lubricates the roller pins, redundant grease can be stored in a cavity formed between the peripheral surfaces of the roller pins and the side wall of the connecting beam 5, the roller pins are continuously lubricated, and the contact area between the roller pins and the side wall of the connecting beam 5 is smaller due to the fact that the side wall of the connecting beam 5 forms an obtuse angle, so that the friction loss of the bearing in operation is reduced, the service life of the bearing is prolonged, and the production cost is saved.
By changing the shape structure of the flanges at the two ends of the window hole 4 of the retainer, the space of the mold core of the retainer is increased, the rigidity is improved, the problem that the mold core shaft is easy to break after being pressed is solved, the structural problem of the mold is solved, and the mass production of the retainer is realized.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
