ZT basic production process of rolling bearings
Due to the different types, structure type, tolerance level, technical requirements, and bulk materials such as rolling bearings, the basic production process is not the same.
A variety of bearing the main parts of the process:
1. Ferrule process: the bearing inner and outer rings of the processing of raw materials or blank forms depending differ, which processes the car before processing can be divided into the following three types, the whole process is: bar or tube feeding (subject to some bar forging and annealing, normalizing) ---- Car ---- grinding heat treatment processing ---- ---- lapping or polishing ---- Part final inspection ---- rust ---- storage ---- (to be fit suit with>
2. Ball of the process, according to the state of the ball in the processing of raw materials also differ, which processes setback before the cut or ball of light can be divided into the following three, before the heat treatment process can be divided into the following two kinds, the whole process is: cold red bar or wire (red zone and need some bar annealed cold punch) ---- setback cut, coarse, soft grinding or ball of light ---- Heat Treatment - --- Hard grinding mill ---- ---- ---- lapping or polishing final inspection group ---- rust, packaging ---- warehousing <suit to be combined with>.
3. Roller roller machining process according to different raw materials vary, which before the heat treatment process can be divided into the following two, the whole process is: bar car after processing or cold heading wire string annulus and Polishing ---- Heat Treatment ---- string soft spots ---- coarse outer diameter ---- roughing end face ---- end face grinding ---- finely grind the outer diameter of the outer diameter ---- Final ---- final inspection group ---- rust, packaging ---- storage (subject to co-suit with>.
4. The process maintain the retainer cage depending on the process design of the structure and materials can be divided into the following categories:
(1) sheet metal stamping → cutting → punching → → → shaping and finishing pickling or shot or string light rust → → final inspection, packing → warehousing (to be combined with packages)
(2) the entity to keep the process frame: solid frame to keep working, according to raw materials or a bad hair differ, of which the first process can be divided into the following four cars rough type, the whole process is: bar, tubing, forgings, castings ---- car inside diameter, outside diameter, face, chamfer ---- Drilling (or broaching, boring) ---- pickling ---- final inspection ---- rust, packaging ---- warehousing <pending suit together with>.
Second, the rolling bearing assembly:
Rolling bearing parts such as the inner and outer rings, rolling elements and cage, etc., after passing inspection, assembly plant for assembly into its process is as follows:
Parts demagnetization, cleaning → inner and outer roll <ditch> channel size grouping together sets of sorting → → → Check clearance riveting cage → → demagnetization final inspection, cleaning → rust, into finished products packaging → (packing, shipping >.
