specific Embodiment approach 1

[0044] Specific implementation mode one: combine Figure 1 to Figure 12 Describe this implementation mode, it of this implementation mode comprises following concrete steps:

[0045] Step 1. Forming: process the formed semi-cage blank;

[0046] Step 2. Oil immersion: immerse the semi-cage blank in the engine oil, 30-50mm away from the oil liquid, the oil immersion time is 8-12 hours, and the oil immersion temperature is 110-120°C;

[0047] Step 3, thin car: the upper end face and chamfer of the fine car half cage 7-1; the lower end face and chamfer of the fine car half cage;

[0048] Step 4, sticking the aluminum sheet: bonding one end face of the half cage 7-1 to the aluminum sheet 10;

[0049] Step 5, bonding the end faces of the two and a half cages 7-1 that are not bonded to the aluminum sheet together;

[0050] Step 6. Roughly grinding the outer diameter of the bonded cage 7 in step 5;

[0051] Step 7, fine-turning the inner diameter of the cage 7;

[0052] Step 8. D...

specific Embodiment approach 2

[0070] Specific implementation mode two: combination Figure 9 To illustrate this embodiment, the thickness of the aluminum sheet in Step 4 of this embodiment is 0.4 mm. With such setting, the strength of the end face of the cage can be enhanced, and the drilling performance can be improved. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0071] Specific implementation mode three: combination figure 1 To illustrate this embodiment, when drilling the rivet hole in step 8 of this embodiment, the feed rate f of the drill bit is: 0.8-1mm / time, and the drill bit speed is 5000r / min. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention provides a method for processing a phenolic tape separation type solid cage, and relates to a processing method of a cage. In order to solve the problems that cracks occur easily on theend face of the cage when a rivet hole is punched in an existing cage made from a phenolic tape material and the outer diameter swells when a pocket is machined, the method comprises the following steps of forming, oil immersing, end face fine lathing and beveling, aluminum sheet adhering, bonding of two semi-cages, outer diameter coarse grinding, inner diameter fine lathing, rivet hole punching,rivet hole beveling, pocket milling, outer diameter finish grinding, inner diameter finish lathing and beveling, assembly line drawing, deburring, forcing apart, binding, adhesive cleaning, polishing,oil immersing, final detecting and packaging. The method is used for processing the phenolic tape separation type solid cage.

Description

technical field [0001] The invention relates to a processing method of a cage, in particular to a processing method of a phenolic tape separation type solid cage. Background technique [0002] When the rolling bearing is working, especially when the load is complex and rotates at high speed, the cage has to bear a lot of centrifugal force, shock and vibration, there is a large sliding friction between the cage and the rolling elements, and a lot of heat is generated. The result of the combined action of force and heat can lead to failure of the cage, and in severe cases, it will cause burns and fracture of the cage. Therefore, the cage material is required to have good thermal conductivity, good wear resistance, small friction coefficient, low density, certain strength and toughness, and good processing performance. Commonly used cage materials are mainly divided into metal and non-metal materials. The material of the phenolic tape-separated solid cage is soft and the wall ...
