Description

Technical Field

[0001] The utility model mainly relates to the technical field of turntable bearings, in particular to a bearing roller retainer. Background Art

[0002] At higher rotational speeds, the turntable bearing is often designed as a rolling bearing, wherein different designs can be used in a manner coordinated with the bearing load.

[0003] The rollers of a conventional turntable bearing cage are often evenly arranged around the cage ring axis. This arrangement causes multiple rollers to roll with the cage ring at the same time during the rolling process, which can easily cause resonance and affect the stability of the bearing during use. Utility Model Content

[0004] The utility model mainly provides a bearing roller retainer to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A bearing roller retainer comprises a first retainer retainer ring and a first retainer ring, characterized in that a second retainer retainer ring and a second retainer ring are arranged in the ring body of the first retainer ring, the first retainer retainer ring, the second retainer retainer ring and the second retainer ring are connected in sequence from outside to inside, a plurality of roller holes are arranged on the side surfaces of the ring bodies of the first retainer ring and the second retainer ring, rollers are inserted in the insides of the roller holes; the axial angles of adjacent roller holes on the first retainer ring and the second retainer ring are not equal.

[0007] Furthermore, the first retaining frame retaining ring and the first retaining frame ring are connected by bolts.

[0008] Furthermore, the roller holes on the first retainer ring and the second retainer ring are both located on a side away from the axis.

[0009] Furthermore, a gap is provided between the roller hole and the roller, and the gap is used to store lubricating oil.

[0010] Furthermore, the axis center of the first retainer retaining ring is the same as the axis center of the first retainer ring, the second retainer retaining ring and the second retainer ring.

[0011] Furthermore, the first retaining frame retaining ring and the first retaining frame ring are connected by bolts.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The angle between the axis of the roller and the center of the circle of the utility model is set to be unequal, so that when the roller rotates with the bearing, the landing point of the roller is different and random, which prevents multiple rollers from rolling synchronously when the roller rolls with the retaining frame, reduces the resonance when the roller rolls, and improves the shock resistance and stability.

[0014] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] For examples, please refer to the attached Figure 1-4 A bearing roller retainer comprises a first retainer ring 1 and a first retainer ring 2, wherein a second retainer ring 3 and a second retainer ring 4 are arranged inside the ring body of the first retainer ring 2, wherein the first retainer ring 1, the first retainer ring 2, the second retainer ring 3 and the second retainer ring 4 are sequentially connected from outside to inside, and a plurality of roller holes 5 are arranged on the side surfaces of the ring bodies of the first retainer ring 2 and the second retainer ring 4, and rollers 6 are inserted into the roller holes 5.

[0024] For details, please refer to the attached Figure 1-3 , the first retainer ring 1 is connected to the first retainer ring 2 by bolts;

[0025] It should be noted that, in this embodiment, since the first retaining ring 1 and the first retaining ring 2 are connected by bolts, and the roller 6 is placed in the roller hole 5 obtained by milling the hole on the side of the retaining ring, the retaining ring can ensure that the roller 6 is fixed in the roller hole 5 during installation and disassembly, and the roller hole 5 is blocked to prevent the roller 6 from falling and scattering.

[0026] For details, please refer to the attached Figure 1-3 , the roller holes 5 on the first retainer ring 2 and the second retainer ring 4 are both located on the side away from the axis;

[0027] A gap is provided between the roller hole 5 and the roller 6, and the gap is used to store lubricating oil;

[0028] It should be noted that, in this embodiment, the roller 6 is wrapped by the roller hole 5, so that a certain amount of lubricating oil can be stored between the roller hole 5 and the roller 6 to provide lubrication for the roller 6 at any time, thereby improving the service life of the roller 6 and the bearing.

[0029] For details, please refer to the attached Figure 1-3 , the axis center of the first retainer retainer ring 1 is the same as the axis center of the first retainer ring 2, the second retainer retainer ring 3 and the second retainer ring 4;

[0030] The axis angles of adjacent roller holes 5 on the first cage ring 2 and the second cage ring 4 are not equal;

[0031] It should be noted that, in this embodiment, the angle between the axis of the roller 6 and the center of the circle is set to be unequal, so that when the roller 6 rotates with the bearing, the landing point of the roller 6 is different random points, which improves the shock resistance and stability.

[0032] The specific operation mode of the utility model is as follows:

[0033] Since the first retainer ring 1 is connected to the first retainer ring 2 by bolts, and the roller 6 is placed in the roller hole 5 obtained by milling the hole on the side of the retainer ring, the retainer can ensure that the roller 6 is fixed in the roller hole 5 during installation and disassembly, and the roller hole 5 blocks the roller 6 from falling and scattering.

[0034] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
