Basic production of rolling bearings

Author:   Date:2013/9/23

Due to the bearing type, structure, tolerance levels, technical requirements, different materials and bulk, the basic production process is not exactly the same.
A, bearing the main parts of the processing procedures:
1. Rings of processing process: bearing within circle and outer ring of processing according to raw materials or rough form of different and different, which car processing Qian of processes can is divided into following three kind of, whole processing process for: great material or tube material (some great material needed by forging and annealing, and are fire)----car processing----heat treatment----grinding processing----refinements of or polishing----parts finally seized----rust----storage----(stay collection sets Assembly 〉
2. Steel ball of processing process, steel ball of processing also according to raw materials of State different and differ, which contusion and cut or light ball Qian of processes, can is divided into following three species, heat treatment Qian of processes, and can is divided into following II species, throughout processing process for: Rod material or wire pressing Dise (some Rod material cold rushed Hou also needed rushed ring with and annealing)----contusion and cut, and rough mill, and sharpens or light ball----heat treatment----hard mill----fine mill----sifted or grinding----end seized group----rust, and packaging----reporting-as-finished straddling Assembly.
3. Roll child of processing process roll child of processing according to raw materials of different and different, which heat treatment Qian of processes can is divided into following two kind of, whole processing process for: great skip processing or wire cold heading Hou string ring with and the sharpens and----heat treatment----string soft points----rough grinding od----rough grinding end surface----finally grinding end surface----fine grinding od----finally grinding od----finally seized group----rust, and packaging----storage (stay collection sets Assembly 〉.
4. Cage cage processing processing according to the different design and raw materials can be divided into the following two categories:
(1) → → → cut punching of sheet metal forming ¡ú shaping and finishing pickling or shot or cross talk → → antirust and packaging final → → library (to be assembled)
(2) entity keep rack of processing process: entity keep rack of processing, according to raw materials or hair bad of different and differ, which car processing Qian can is divided into following four species rough type type, throughout processing process for: Rod material, and tube material, and forgings, and casting----car bore, and OD, and end surface, and pour corner----drilled (or pulled hole, and bores)----pickling----end seized----rust, and packaging----reporting-as-finished straddling stay collection sets Assembly 〉.
B, rolling bearing Assembly process:
Rolling bearing parts such as inner and outer rings, rolling elements and cage, after an inspection into the fitting for Assembly, the process is as follows:
Demagnetization, washing parts road → rolled inside and outside the ditch dimensions group sorting check clearance → → → riveted cage → check → demagnetization, washing → → rust and packaging them into finished goods warehouse (packing, shipping.
