What are the different types of the basic production process of rolling bearings

wallpapers Low Carbon 2020-07-29
Due to the different types, structural types, tolerance levels, technical requirements, materials and batch sizes of rolling bearings, the basic production process is not exactly the same.
 
Processing process of main parts of various bearings:
 
1. The processing process of the ferrule: The processing of the inner ring and the outer ring of the bearings varies according to the different raw materials or blank forms. Among them, the processes before turning can be divided into the following three types. The entire processing process is: Bar or tube (Some bars need to be forged, annealed and normalized)-turning-heat treatment-grinding-lapping or polishing-final inspection of parts- Rust prevention ---- warehousing ---- (to be matched with suit)
 
2. The processing process of the steel ball, the processing of the steel ball also differs according to the state of the raw material, the process before the frustration or the photoball can be divided into the following three types, and the process before the heat treatment can be divided into the following Two types, the whole processing process is: cold punching of bar or wire (some bars need to be punched and annealed after cold punching)-frustration, rough grinding, soft grinding or light ball-heat treatment- ---Hard grinding-fine grinding-fine grinding or grinding-final inspection group-rust prevention, packaging-warehousing (to be fitted with a set).
 
3. Roller processing process The processing of the roller varies according to the different raw materials. The process before heat treatment can be divided into the following two types. The entire process is: bar turning or wire cold heading after stringing and soft grinding ----Heat treatment----string soft spots----coarse grinding outer diameter----rough grinding end face----final grinding end face----fine grinding outer diameter----final grinding outer diameter ----Final Inspection Group----Anti-rust, Packaging----Warehousing (to be matched with suits).
 
4. The processing process of the cage The processing process of the cage can be divided into the following two categories according to the design structure and raw materials:
 
(1) Sheet material → shearing → punching → stamping forming → shaping and finishing → pickling or shot peening or stringing → final inspection → rust prevention, packaging → storage (to be matched with suits)
 
(2) The processing process of the solid cage: The processing of the solid cage varies according to the raw material or the roughness. Before turning, it can be divided into the following four types of blanks. The entire processing process is: bar, Pipe material, forgings, castings-car inner diameter, outer diameter, end face, chamfer-drilling (or pull hole, boring)-pickling-final inspection- Anti-rust, packaging ---- warehousing (to be matched with a suit).
 
The assembly process of rolling bearings:
 
Rolling bearing parts such as inner ring, outer ring, rolling element and cage, etc., after passing the inspection, enter the assembly workshop for assembly. The process is as follows:
 
Parts demagnetization, cleaning→internal and external rolling <groove> channel size grouping selection→fitting→check clearance→riveting cage→final inspection→demagnetization, cleaning→rust prevention, packaging→into the finished product warehouse (packing, shipping >.
