Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of high-precision wide slab flattener backing roll bearing.
Background technique
Wide Heavy Plate Leveler back-up roll at present in accurate plate-straightening machine comprises support outer ring, rotating shaft, some back lining bearings and sealing cover; Wherein some back lining bearings are sleeved in rotating shaft, support outer ring sleeve and are contained in outside some bearing of straightening machines, install a sealing cover respectively at the outer rod two ends of support; Before use, first support outer ring, rotating shaft, some bearing of straightening machines and sealing cover scene will be assembled, it uses installation loaded down with trivial details to this Wide Heavy Plate Leveler back-up roll; And owing to being provided with some bearing of straightening machines in support outer ring, make each back lining bearing cannot carry out highi degree of accuracy assembling with support outer ring and rotating shaft, thus in use bearing of straightening machine with support outer ring and rotating shaft and easily produce and wear and tear and affect the quality of production of accurate sheet material, simultaneously more loaded down with trivial details when back lining bearing being carried out from Wide Heavy Plate Leveler bracing ring after back lining bearing weares and teares dismounting reparation.
Summary of the invention
For above-mentioned shortcoming, the purpose of this utility model is to provide a kind of high-precision wide slab flattener backing roll bearing with improving production sheet material precision easy to install.
Technology contents of the present utility model is: high-precision wide slab flattener backing roll bearing, it is characterized in that it comprises and supports outer ring, rotating shaft, needle roller, cages for needle, thrust ball bearing, back-up ring, seal ring and dust ring; Inside the two-port supporting outer ring, be respectively provided with a recess, rotating shaft is arranged on and supports in outer ring, and rotating shaft is provided with 2 ~ 4 cages for needles, and each cages for needle is provided with several needle rollers; In the recess supporting outer ring, be respectively provided with a thrust ball bearing, the rotating shaft outside each thrust ball bearing is provided with back-up ring, seal ring and dust ring from inside to outside successively; Be provided with an oil hole in rotating shaft one end, oil hole is used for injecting oiling agent to needle roller, cages for needle and thrust ball bearing.
The utility model is compared with prior art advantageously: the utility model adopts integrated design, directly can be installed in accurate plate-straightening machine, use without the need to assembled in situ, it can improve produces sheet material precision, in using, wearing and tearing are few simultaneously, long service life; Structure is compacter, and radial structure size is less, saves mechanical space.
