Pressing plate ball bearing capable of reducing pressing force

Abstract

The utility model relates to a pressing plate ball bearing capable of reducing pressing force. The pressing plate ball bearing is provided with a pressing plate installed on one side of the end face of a bearing. A notch matched with the pressing plate is formed in one side of the end face of the bearing; the bottom face of the notch is a plane matched with the end face of the pressing plate. The side face of the notch is a pressing face matched with the side face of the pressing plate, and the pressing face is an inclined face. The angle of the inclined surface is 5-10 degrees; and the bottom surface of the notch is connected with the inclined surface through an arc chamfer. When the pressing plate is deformed during installation, the pressure formed on the pressing surface is relatively uniform, and the risk of damage to the pressing surface is reduced. And the chamfered part ensures the strength of the joint, so that cracks are avoided when the pressing force is too large.

Description

TECHNICAL FIELD

[0001] The utility model relates to bearing technical field, mainly relates to a kind of pressing plate ball bearings for reducing pressure. BACKGROUND

[0002] Pressing plate ball bearings are widely used in automobile reduction gearbox, for supporting gear shaft;Pressing plate is installed in bearing end side, and is fixed in reduction gearbox shell by bolt to limit axial position;Since reduction gearbox shell is aluminum alloy material, aluminum alloy is deformed during bolt tightening process, leading to slight deformation of pressing plate, finally making the pressing force of pressing plate on bearing end face be larger and uneven, with the possibility of outer ring steel extrusion damage. SUMMARY

[0003] To solve the problems in the background art, the utility model aims at providing a kind of pressing plate ball bearings for reducing pressure.

[0004] The utility model discloses a kind of pressing plate ball bearings for reducing pressure, which uses the following technical solutions to achieve the above-mentioned purposes:

[0005] A kind of pressing plate ball bearings for reducing pressure, pressing plate ball bearing has the pressing plate installed in one side of bearing end face;One side of the bearing end face has the slot for cooperating with the pressing plate;The bottom surface of the slot is the plane for cooperating with the end face of the pressing plate;The side surface of the slot is the pressing surface for cooperating with the side surface of the pressing plate, and the pressing surface is inclined surface;The angle of the inclined surface is 5 °-10 °;The bottom surface of the slot and the inclined surface are connected by circular arc chamfer.

[0006] The bottom surface of the slot is horizontal plane, and the chamfer is located on the horizontal plane, and the circular arc is R.

[0007] The utility model discloses a kind of pressing plate ball bearings for reducing pressure, by the implementation of the above technical solutions, the utility model pressing plate is more uniform when installing deformation, reduces the risk of damage to pressing surface.The chamfer part ensures the strength of the connecting angle, so as not to crack when the pressing force is too large. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 The utility model discloses a structure schematic diagram.

[0009] Figure 2 For Figure 1 A portion of the enlarged view.

[0010] In the figure: 1, bearing, 2, pressing plate, 3, horizontal plane, 4, chamfer, 5, pressing surface. DETAILED DESCRIPTION

[0011] The present application is described in conjunction with the drawings and specific embodiments.

[0012] AsFigure 1 As shown in the figure, a kind of pressing plate ball bearing for reducing pressing force, the pressing plate ball bearing has pressing plate 2 installed on one side of bearing end face;The one side of the bearing end face has a lack of slot to cooperate with the pressing plate;The bottom surface of the lack of slot is a plane to cooperate with the end surface of the pressing plate;The side surface of the lack of slot is a pressing surface 5 to cooperate with the side surface of the pressing plate, and the pressing surface is an inclined surface;The angle of the inclined surface is 5°-10°;The bottom surface of the lack of slot and the inclined surface are connected by a circular arc chamfer.

[0013] The bottom surface of the lack of slot is a horizontal plane, and the chamfer is located on the horizontal plane, and the circular arc is R.

[0014] When the pressing plate bearing is installed, the bearing 1 is placed in the shell 3, and the pressing plate 2 is fixed on the shell by the bolt 4, because the shell is made of soft aluminum alloy material, deformation is easy to occur. The pressing plate will be deformed, and a larger pressing force will be generated on the pressing surface 5.

[0015] The part not described in detail is prior art.
