Rolling type, structure type, tolerance level, technical requirements, materials and quantities of the different, the basic production process is not exactly the same.angular contact bearings
Processing of the various bearings main parts:
A. Process of the rings: the bearing inner ring and outer ring of processing according to the different raw materials or rough form is different, where the car before processing process can be divided into the following three, the whole process is:
Bar or tube material (some bar subject to the forging and annealing, normalizing) ---- car processing ---- Heat Treatment ---- grinding ---- lapping or polishing ---- Part final check ---- the antirust ---- storage ---- (to be co-suite with);
Two. The process of the ball, the ball of processing according to the status of raw materials vary, which fell cut or ball of light before the process can be divided into the following three, before the heat treatment process can be divided into the following two kinds, the whole process: the bar or wire rod cold red (some bar cold red need to red ring and anneali ng) ---- setback cut, coarse, soft grinding or ball of light ---- Heat Treatment - --- ---- grinding hard grind ---- lapping or grinding ---- final inspection packet ---- anti-rust packing ---- storage <to be co-suite with>;
3. Process roller roller processing according to the different raw materials, before the heat treatment process can be divided into the following two, the whole process is: after the car processing of bar or wire rod for cold heading string band and soft tactics ---- Heat Treatment ---- string soft spot ---- coarse grinding outer diameter ---- coarse grinding end ---- end face grinding ---- finely ground outer diameter ---- end of grinding the outside diameter ---- end packet inspection ---- anti-rust packing ---- storage (to be co-suite with>;FAG bearing
4. The process of the cage to cage the process according to different design and raw materials can be divided into th e following categories:
(1) strip → shear → blanking → stamping forming → shaping and finishing → pickling or shot blasting, or string light → final inspection, anti-rust → packaging → warehousing (to be co-suite with);
(2) physical cage process: the physical cage processing vary according to raw materials, or bad hair different, which type of car before processing can be divided into the following four rough, the whole process: the bar tubing, forgings, castings ---- car inside diameter, outside diameter, face, chamfer ---- drilling (or broaching, boring) ---- pickling ---- final inspection ---- rust, packaging ---- warehousing "to be co-suite with>.
Second, the rolling bearing assembly process:
Rolling bearing parts such as the inner ring, outer ring, rolling body and cage, etc., after passing inspection, the assembly workshop for assembly, and its process is as follows:
Demagnetization of parts, the outer raceway <ditch cleaning →> Road size grouping sorting> co-sets → Check the clearance → riveting cage → → demagnetization of the final inspection, cleaning → anti-rust packing → into finished products (packing, shipping >.precision bearings
