Problems solved by technology

Although the rolling bearing technology has a high maturity and has formed serialized parts, which can be directly selected as standard parts, its own characteristics such as large volume, heavy weight, loud running noise, and short life directly affect the use of plunger pumps, resulting in the current The plunger pump has heavy weight, loud working noise, short life, and large vibration after long-term operation, which has become one of the bottleneck factors restricting the life and reliability of the plunger pump.

Embodiment Construction

[0014] The present invention will be described in further detail below. see figure 1 , The present invention is a cylindrical single structure bearing processed by a complete machine. There is a raised cylindrical surface 1 on the outer cylindrical surface of the bearing, and the cylindrical surface 1 is a positioning structure surface, which is matched with the inner hole of the housing to locate the radial position of the bearing; the two sides of the cylindrical surface 1 on the outer peripheral surface of the bearing are conical surfaces 2 In order to guide the mounting surface and facilitate the installation or disassembly of the bearing, the bottom surface of the conical surface 2 is close to the cylindrical surface 1; the cylindrical surface 1 has a positioning hole 5, which is a through hole, located in the area opposite to the radial load of the bearing, and used for positioning The circumferential and axial position of the bearing; the inner surface of the bearing i...

Abstract

The invention relates to bearings, in particular to a sliding bearing. The bearing is of a cylindrical monomer structure. The peripheral surface of the bearing is provided with a convex cylindrical surface (1) which is a locating structural surface; the both sides of the cylindrical surface of the peripheral surface of the bearing are conical surfaces, and the bottom surfaces of the conical surfaces are close to the cylindrical surface (1). The designed locating structural surface in the technical scheme is high in locating accuracy, and the required installation space is small. The designed guide installation surface in the technical scheme facilitates installation and removal of the bearing.

Description

technical field [0001] The invention relates to a bearing, in particular to a sliding bearing Background technique [0002] In the prior art, compared with rolling bearings, sliding bearings have the characteristics of light weight and long service life, but the current sliding bearings are assembled with multiple parts, resulting in larger sizes, and due to the low maturity of the technology, problems occur during the use of sliding bearings. Partial wear, abnormal wear and other problems affect the reliability and service life of the product. For example, in the structural design of the aeroengine plunger pump, the bearing is an important part of the transmission support, which is directly related to the stability and service life of the plunger pump. Now the bearing structure design usually directly selects standard rolling bearings or customizes special rolling bearings according to design needs. Although the rolling bearing technology has a high maturity and has formed...
