Can I say something in detail? What about the surface of the Dragon joint bearing?
These things belong to the trade secret, must have the patent... You want to spend hundreds of thousands of dollars to buy ah... How to think of the Internet to find it?
I. the processing of various main parts of bearings:Processing: processing 1. rings of bearing inner ring and outer ring in the stock of raw materials or different, the car before the machining process can be divided into the following three kinds, the whole process is that the bar or pipe material (some bar by forging and annealing, normalizing, thermal processing) - car processing - grinding - lapping or polishing, final inspection parts ---- ---- ---- (to be closed storage antirust suits.The machining process of 2. steel balls, steel ball processing the same as raw material status varies, which cut the ball or contusion process can be divided into the following three, before the heat treatment process, and can be divided into the following two kinds, the whole process for bar or wire punching (with the the bar is red band cold punching and annealing) - cutting, grinding, polishing and polishing, or heat treatment - hard abrasive grinding, lapping or polishing ---- ---- ---- rust and final inspection group "to close packing - storage suits.3. roller roller machining process according to different raw materials, including before heat treatment process can be divided into the following two kinds, the whole process is: rod or wire cold skip processing on zoning and soft - heat treatment on soft, coarse grinding, coarse grinding diameter - end - end mill end - fine grinding diameter - Final grinding diameter - final inspection packet -- rust and packaging -- storage (to be closed suit with.
4., the processing process of cage, cage processing process, according to the design, structure and raw materials, can be divided into the following two categories:(1) sheet material: cutting, punching, punching, stamping, reshaping, finishing, finishing, pickling or shot blasting, or folding, final inspection, rust proof, packing and warehousing (to be matched with suits)(2) entity to keep process frame: solid cage processing, according to raw materials or bad hair will be different, the car before processing can be divided into the following four types of blank, the whole process is: excellent material, pipe material, forging, casting, car inner and outer diameter and end face, chamfer - Drilling (or pull holes, boring) ---- ---- ---- pickling rust and final inspection packing storage "to be together -- suits.Two, rolling bearing assembly process:Rolling bearing parts such as inner ring, outer ring, roller 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, size, grouping, sorting, sealing, checking, clearance, riveting, retaining frame, final inspection, demagnetization, cleaning, rust prevention, packing and entering into the finished product warehouse (packing and shipping).
