A flexible fixture for rolling element bearings for coating

A rolling element bearing for coating of the flexible fixture - 2019 04 - 12 to get rich, Shanghai university of applied technology) Public patent no. : 108060405 a patent name: a rolling element bearing for coating of the flexible fixture 【 Patent background 】 With the progress of bearing manufacturing technology level of ascension and the user's demand, the bearing's life and self-lubricating properties put forward higher requirements. The traditional bearing use lubricating oil or grease, not only waste the cost, but also caused certain pollution to the environment, not adapt to the development direction of the green manufacturing. And physical vapor deposition technology is a kind of green pollution-free surface modification technology, has developed greatly, and in the aerospace, automobile manufacturing, mould, cutting tools, bearings and other fields is widely used. For bearings, the rolling body low-temperature coating processing, not only can reduce the surface friction and reduce wear and tear, and can improve the service life of the bearing as a whole. But at the moment of bearing roller coating processing, easy to appear the phenomenon such as insufficient coating coated. The above phenomenon is easy to cause the roller in the process of work stress is not uniform, partial wear serious, affect the bearing deadlines. The study found that the reasons for the above phenomenon and preparation of coating on the surface of the clamping roller way. Therefore, the present invention, on the basis of summarizing the problem of the new idea in the form of the clamping roller coating design a can realize stable clamping, uniform coating deposition and can meet the different specifications of bearing roller coating fixture. The jig to avoid the dedicated fixture, has the characteristics of flexibility and flexible. To save the cost of production at the same time, improve production efficiency. 【 The patent content 】 The invention is mainly aimed at the rolling element bearing in insufficient coating, coating thickness uneven phenomenon, such as design of a compact structure, strong adaptability, high flexibility of bearing roller coating fixture. 【 Patent description 】 The present invention includes positioning sleeve ( 1) , support disk ( 2) And socket head bolts ( 3) And the disk ( 4) Article, rolling element bearing support 5) , on the disc ( 6) , double end studs ( 7) , adjusting nut ( 8) , fixed bolts ( 9) , rolling element bearing ( 10) 。 On the disc ( 6) And the disk ( 4) Through the double end studs connection, upper and lower support article on disk ( 5) Through the socket head bolts ( 3) Fixed onto the disk, below support disk in the disk, used to support the rolling element bearing ( 10) Clamping part, a positioning sleeve on support under the disc, the side has threaded hole, with bolt locking adjust the clip in the furnace chamber of the upper and lower position. Is a kind of compact structure, strong adaptability, high flexibility of bearing roller coating fixture. 【 Innovative 】 1. Through the inner hex bolt tightening and relax regulation article support extended length to the different specifications of the clamping roller. 2. Adjusting nut can be adjusted according to the height of rolling element vertical distance between the two disks. 3. Positioning sleeve through the retaining bolt tightening rotary furnace at a fixed frame.
