Problems solved by technology

[0003] In order to solve the problem that the lubricating grease between the inner and outer rings and the cage is squeezed out, resulting in contact between the inner and outer rings and the cage, causing fatigue spalling and abrasive wear, and finally the cage is broken and the bearing fails. , and then proposed a method of using laser texturing to manufacture anti-wear cages and rolling bearings

specific Embodiment approach 1

[0022] Specific implementation mode one: combine figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 with Image 6 Describe this embodiment, the method of this embodiment includes the following steps:

[0023] Step 1: Hydroacoustic detection step: select a cage blank, conduct non-destructive inspection on the blank by underwater acoustic detection, and use the blank that meets the relevant requirements as the original block of the cage to be processed in the next step;

[0024] Step 2: Rough and fine processing of the cage: According to the requirements of the relevant drawings, the original block of the cage that has passed the flaw detection in step 1 is processed. First, the outer circle of the original block of the cage is roughly turned, and secondly, the two parts of the original block of the cage are finely turned. The end face, then the inner circle of the original block of the cage is thinned, and finally pocket holes are drilled on the original block of the ...

specific Embodiment approach 2

[0037] Specific embodiment 2: This embodiment is a further limitation of specific embodiment 1. This embodiment also includes step 6. Step 6 is a further processing step. This step is the outer circle of the cage 3 in step 4 of fine turning, and the step of finalizing the car Fourth, the cage 3 has two planes, and the surface burr of the cage 3 is removed.

specific Embodiment approach 3

[0038] Specific Embodiment 3: This embodiment is a further limitation of Specific Embodiment 2. This embodiment also includes step 7, which is a dynamic balance detection step. This step is to perform dynamic balance detection on the cage 3 processed in step 6. , the cage 3 that meets the requirements is put into subsequent processing steps, otherwise it is treated as waste.

Abstract

The invention discloses a method for manufacturing a wear-resistance cage by laser texturing and a rolling bearing, relates to the cage manufacturing method and the rolling bearing consisting of cages manufactured by the method, and aims to solve the problem of bearing failure caused by final rupture of the cages due to fatigue flake and abrasive wear caused by contact between inner and outer sleeve rings and the cages due to extrusion of lubricating oil between the inner and outer sleeve rings and the cages. The method comprises a water sound detecting step, a rough-finish machining step of the cages, a debugging step, a focusing step and a surface texturing step; the rolling bearing includes the outer sleeve ring, the inner sleeve ring, the cages and multiple rolling bodies; the inner sleeve ring is sleeved in the outer sleeve ring, and the two are coaxially arranged; the cages are arranged between the outer sleeve ring and the inner sleeve ring; the multiple rolling bodies are correspondingly arranged in multiple pocket holes on the cages one to one; and multiple upper texturing units and multiple lower texturing units are machined on the outer circular surfaces of the cages. The method is used for the bearing manufacturing process.

Description

technical field [0001] The invention relates to a method for manufacturing an anti-wear cage and a rolling bearing, belonging to the technical field of mechanical manufacturing. Background technique [0002] Bearings are the core components of mechanical systems, and their performance is related to the rotational accuracy, stability, reliability and service life of mechanical devices. Rolling bearings are the most widely used type of bearings and consist of rolling elements, inner and outer rings and cages. When the rolling bearing is running at high speed, the cage and the ring are subjected to repeated impact and sliding during the working process, so that the lubricating grease between the ring and the cage is squeezed out, resulting in contact between the ring and the cage. Fatigue spalling and abrasive wear are caused. After long-term operation, excessive wear occurs on the guide surface of the ferrule and cage, which makes the guide surface of the cage and ferrule thi...
