Embodiment Construction

[0020] In conjunction with accompanying drawing, process of the present invention is described in detail:

[0021] as attached image 3 As shown, during lathe processing, 4 ring-shaped process guide grooves 2 and 3 are opened on the middle position of the outer diameter generatrix of the SL01 type split bearing outer ring 1 and on the relative position of the raceway (the position to be cut), and the opened guide grooves 2, 3 perpendicular to the axis of the bearing; as attached Figure 4 As shown, after the grinding process is completed, a transverse incision 7 is made by wire cutting along the guide groove. The length of the incision depends on the size of the bearing diameter, which is about 1 / 8 of the circumference of the bearing outer ring; Apply a certain force to divide the outer ring into two to realize splitting. After the product is assembled, it is docked according to the original interface, and then three lock rings 5 ​​are respectively installed in the three loc...

Abstract

The invention relates to the technical field of technical processing of a bearing. A process method for the split processing of an SL type split bearing comprises the following steps: 1. when a product is processed by a lathe, opening annular guiding process grooves at the middle position of the generating line of an outer ring of a bearing to be split and at a position corresponding to a ball race, wherein the wall thickness between two notches is determined according to the allowance size of the grinding procedure provided by the turning procedure so as to ensure that the wall thickness between the two notches of a finished product is between 1.5 and 2 millimeters; 2. after finishing all the grinding processing procedures on the outer ring and before the assembling procedure, opening a transverse incision on the outer ring to be split along a guiding groove in a linear cutting mode, wherein the length of the incision is determined according to the size of the product; and 3. applying certain force on an opening to divide the outer ring into two parts so as to realize the split. The process method has strong processing manufacturability, can meet the product design requirement and realize batch processing, and improves the processing efficiency.

Description

technical field [0001] The invention relates to the technical field of bearing processing, and mainly relates to a split processing method for SL01 type split bearings. Background technique [0002] SL Cylindrical Roller is a double row full complement roller type super heavy load bearing, which has two types: fixed side (SL01, SL04) and free side (SL02). Thin size series, and can bear very large radial load and impact load, in addition to the radial load, the fixed side bearing can also bear bidirectional axial load through the rollers. Therefore, it has been widely used in construction machinery, vehicles, steel, hoisting machinery and other fields. The outer ring or inner ring of the bearing needs to be divided by a special process in the circumferential direction, and then the rollers are installed and fixed as an integral structure. At present, due to the difficulty in mastering the subdivision process and processing technology in China, there are only a few enterprise...
