Simple pressing plate ball bearing

Abstract

The utility model relates to a simple pressure plate ball bearing which is provided with an L-shaped pressure plate, and one side of the bottom surface of the pressure plate is provided with a bulge protruding downwards; an end surface groove matched with the bulge is formed in one side of the bearing outer ring corresponding to the bulge; the pressing plate is nested on the outer side of the bearing outer ring, and the pressing plate and the bearing outer ring are in transition fit; a gap is formed between the protrusion on the pressing plate and the end face groove. The protrusions form limiting protrusions used for blocking and limiting the installed bearing. The pressing plate is not fixed by a third part; the bearing is hooped in the pressing plate and is fixed by means of transition fit with the outer ring of the bearing. The end face of the outer ring is only the end face groove, no tooth opening structure exists, and the situation that a tooth opening is broken does not exist.

Description

Technical Field

[0001] The utility model belongs to the technical field of bearings and mainly relates to a simple pressure plate ball bearing. Background Art

[0002] The pressure plate ball bearing is a bearing assembly widely used in automobile gearboxes; the pressure plate is fixed to one side of the outer ring of the bearing, integrated with the bearing, and fixed to the gearbox housing by bolts; in the prior art, the pressure plate is mainly fixed by fastening with a third part, such as the three-point clamping ring connection disclosed in CN215861374U; however, during transportation and use, problems such as the pressure plate falling off and the tooth collapse may occur, affecting the reliability of the pressure plate bearing. Summary of the Invention

[0003] In order to solve the problems in the background technology, the purpose of the utility model is to provide a simple pressure plate ball bearing.

[0004] The present invention adopts the following technical solutions to achieve the above-mentioned purpose:

[0005] A simple pressure plate ball bearing, the simple pressure plate ball bearing has an L-shaped pressure plate, and one side of the bottom surface of the pressure plate has a downwardly protruding protrusion; corresponding to the protrusion, an end face groove that cooperates with it is provided on one side of the bearing outer ring; the pressure plate is nested on the outside of the bearing outer ring, and the two are transitionally matched; there is a gap between the protrusion on the pressure plate and the end face groove; the protrusion constitutes a limit protrusion for blocking and limiting the bearing after installation.

[0006] The total width of the pressure plate is no greater than the bearing width.

[0007] The utility model proposes a simple pressure plate ball bearing. Through the above technical solution, the pressure plate of the utility model does not rely on a third part to fix it; the pressure plate inner hoop bearing relies on the transition fit with the bearing outer ring to fix the bearing, and is easier to reassemble even if it falls during transportation; the end face of the outer ring is only an end face groove, without a tooth structure, and there is no possibility of tooth collapse. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] In the figure: 1. bearing, 2. pressure plate, 2.1. protrusion, 1.1. end face groove. DETAILED DESCRIPTION

[0010] The present invention is described with reference to the accompanying drawings and specific embodiments.

[0011] like Figure 1As shown, a simple pressure plate ball bearing has an L-shaped pressure plate 2, and one side of the bottom surface of the pressure plate 2 has a downwardly protruding protrusion 2.1; corresponding to the protrusion 2.1, an end face groove 1.1 is provided on one side of the outer ring of the bearing 1 to match it; the pressure plate 2 is nested on the outer side of the bearing outer ring, and the two are transitionally matched; there is a gap between the pressure plate protrusion and the end face groove; the protrusion constitutes a limit protrusion for blocking and limiting the bearing.

[0012] The total width of the pressure plate is no greater than the bearing width.

[0013] The bearing outer diameter tolerance complies with GB / T 307.1. The inner diameter of the pressure plate is the same as the outer diameter of the bearing outer ring, with a tolerance of H7, thus forming a transition fit.

[0014] The outer ring of the bearing has an end face groove and no tooth gap, and is easy to process.

[0015] During installation, the bearing is pressed into the pressure plate from one side, and the end face is blocked by the protrusion of the pressure plate.

[0016] The parts not described in detail are prior art.

Claims
