Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing ring technology, and more specifically, it relates to bidirectional thrust ball bearing rings. Background Technology
[0002] The bearing races of a double-direction thrust ball bearing are a crucial component of the bearing structure, primarily functioning to support and guide the movement of the rolling elements. These bearings are typically used in applications requiring axial loads in two directions. Double-direction thrust ball bearings need to be installed into components with various bore diameters. Currently, commonly used double-direction thrust ball bearings are usually designed with a fixed diameter, meaning they cannot be flexibly adjusted to meet the specific bore diameter requirements of different components. This can lead to dimensional mismatches in the bearing races, significantly reducing the ease of installation. This not only increases installation difficulty and time costs but may also affect the operational stability and reliability of the entire equipment. Utility Model Content
[0003] This disclosure relates to double-direction thrust ball bearing races to address the issue that commonly used double-direction thrust ball bearings, as mentioned in the background art, typically have a fixed diameter design. This means they cannot be flexibly adjusted according to the specific bore diameter requirements of different components, which may lead to size mismatch issues during installation.
[0004] The purpose and effect of this utility model of a bidirectional thrust ball bearing ring are achieved by the following specific technical means:
[0005] In a first aspect, this disclosure provides a bidirectional thrust ball bearing race, comprising: an inner bearing ring, the inner bearing ring having a circular shape and a connecting outer ring mounted on its exterior; the inner bearing ring further comprising: an outer bearing ring, the outer bearing ring having a circular shape and rotatably disposed outside the inner bearing ring; and two grooves A having an arc-shaped groove shape and symmetrically arranged on the outer side of the inner bearing ring; the connecting outer ring being fixedly mounted outside the outer bearing ring.
[0006] As a preferred embodiment of this utility model, the bearing inner ring further includes a groove B, which has an arc-shaped groove structure design, and the number of grooves B is set to two, with the grooves B being symmetrically opened on the inner side of the bearing inner ring.
[0007] As a preferred embodiment of this utility model, the inner ring of the bearing further includes: a ball, the ball being spherically shaped and rotatably disposed between groove A and groove B.
[0008] As a preferred embodiment of this utility model, the inner ring of the bearing further includes: a cage, which is installed on one side of the balls; the balls rotate on one side of the cage; and the other side of the cage engages with the inner side of the outer ring of the bearing.
[0009] As a preferred embodiment of this utility model, the inner ring of the bearing further includes: fixing holes, the fixing holes being designed with a threaded hole structure, and the number of fixing holes being set to sixteen, the fixing holes being arranged in a ring array on the outside of the outer ring of the bearing.
[0010] As a preferred embodiment of this utility model, the connecting outer ring includes: a reinforcing side ring, which is circular in shape and integrally disposed on one side of the connecting outer ring; and connecting holes, which are circular in shape and eight in number, arranged in a ring array on the outside of the connecting outer ring; the connecting holes and the fixing holes are fixedly connected by a fixing screw threaded connection.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] The fit between the outer ring and the connecting outer ring of the double-direction thrust ball bearing enables it to have good fixation and adjustment capabilities. If a dimensional mismatch occurs during installation, the following adjustments can be made: place the connecting outer ring outside the outer ring of the bearing, ensuring a tight fit, and insert the fixing screws into the connecting hole. Due to the threaded connection between the fixing screws and the fixing hole, tightening the screws securely fixes the connecting outer ring to the outside of the bearing outer ring. This effectively changes the fixing diameter of the double-direction thrust ball bearing raceway, better adapting it to the requirements of the installation environment. Furthermore, a reinforcing side ring is integrally formed on one side of the connecting outer ring, which fits snugly against one side of the bearing outer ring, enhancing the load-bearing capacity of the connecting outer ring. This greatly facilitates subsequent fixing and installation of the double-direction thrust ball bearing raceway, reducing obstacles and difficulties during installation, improving installation efficiency and quality, and ensuring the double-direction thrust ball bearing can stably perform its intended function in the equipment.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0020] Example: As attached Figure 1 To be continued Figure 4 As shown:
[0021] This utility model provides a bidirectional thrust ball bearing race, comprising: an inner bearing ring 1, which is circular in shape, and a connecting outer ring 2 is mounted on the outside of the inner bearing ring 1; the inner bearing ring 1 includes: an outer bearing ring 101, which is circular in shape and rotatably disposed outside the inner bearing ring 1; a groove A102, which is arc-shaped and consists of two grooves symmetrically arranged on the outside of the inner bearing ring 1; the connecting outer ring 2 is fixedly mounted outside the outer bearing ring 101; and a groove B103, which is arc-shaped. The structural design includes two symmetrically arranged grooves B103 on the inner side of the bearing inner ring 1; ball 104 with a spherical shape, rotatably positioned between grooves A102 and B103; cage 105 mounted on one side of ball 104; ball 104 rotatably positioned on one side of cage 105; the other side of cage 105 engaging with the inner side of bearing outer ring 101; and sixteen threaded holes arranged in a circular array on the outside of bearing outer ring 101.
[0022] The connecting outer ring 2 includes: a reinforcing side ring 201, which has a circular shape and is integrally disposed on one side of the connecting outer ring 2; and eight connecting holes 202, which are arranged in a circular array on the outside of the connecting outer ring 2. The connecting holes 202 and the fixing holes 106 are fixedly connected by a fixing screw.
[0023] The specific usage and function of this embodiment: During the use of the double-direction thrust ball bearing ring, the double-direction thrust ball bearing is installed in a suitable mechanical component so that it can be used in conjunction with the component.
[0024] When a size mismatch occurs during the installation of a double-direction thrust ball bearing, the connecting outer ring 2 is placed outside the bearing outer ring 101, and then a fixing screw is inserted into the connecting hole 202. The connecting outer ring 2 is fixed to the outside of the bearing outer ring 101 by threaded connection between the fixing screw and the fixing hole 106. This changes the fixing diameter of the double-direction thrust ball bearing ring, making subsequent fixing and installation of the double-direction thrust ball bearing ring easier.
