Abstract
The invention relates to an embedded locking sendzimir bearing with an ultra-thick cross section and belongs to the technical field of bearing manufacture. An inner ring is arranged on the innermost side of the bearing, horizontal check rings are arranged on the two side faces of the inner ring respectively; a roller spaced by inner spacing rings is arranged on the upper surface of the inner ring; an outer ring of the bearing is arranged above the roller; sealing rings are mounted at the side parts of the outer ring of the bearing; the bottoms of the sealing rings are contacted with the horizontal check rings; oil grooves are formed in the horizontal check rings; and the inner ring is provided with two oil drain holes. The wall thicknesses of the cross section and the outer ring of the bearing are greater than those of the normal cylindrical roller bearing, so that the bearing can bear a greater radial load. A retainer adopts an unique embedded locking structure, so that the bearing is easy to lubricate, mount and dismount, and the manufacturing cost is saved. In addition, according to the bearing, the fitting degree between a rolling body and a roller path is configured reasonably, so that the bearing can adapt to high-load, high-rotation-speed and high-temperature severe working conditions.
Description
Technical fieldThe present invention relates to have the embedded lock-fit-type Senjimier bearing in super thick cross section, belong to bearing manufacturing technology field.
Background techniqueAt present, produce flat cold-rolled sheet and need high-precision Senjimier bearing.The gap that domestic Senjimier bearing is larger with external existence, domestic Senjimier bearing will lean on external import mostly, state's outer bearing price is high and supply untimelyly, causes SUPPLY CHAIN very nervous, and these have seriously restricted the process that China's steel industry development and milling train domesticize.
Summary of the inventionThe present invention is in order to break external technical monopoly for a long time, defective in view of the prior art existence, a kind of embedded lock-fit-type Senjimier bearing with super thick cross section is provided, this bearing is three-row cylindrical roller bearing, bearing cross section and outer ring wall thickness compared with normal roller bearing be thick to be gone out manyly, makes it can bear larger radial load, and retainer adopts unique embedded lock-fit-type structure, so that this bearing is easy to lubricate, installation and removal, and saved manufacture cost.
To achieve these goals, technological scheme of the present invention is: have the embedded lock-fit-type Senjimier bearing in super thick cross section, comprise outer ring, roller, inner ring, embedded lock-fit-type retainer, conventional retainer, cone spacer, seal ring, loose rib; The inside at bearing is inner ring, be respectively equipped with loose rib in two sides of inner ring, the inner ring upper surface is provided with the roller that is separated by cone spacer, it is bearing outer ring above the roller, seal ring is equipped with in bearing outer ring limit section, the bottom of seal ring contacts with loose rib, has oil groove on the described loose rib, and described inner ring is provided with two oil drainage holes.
Described bearing section thickness is 113.21mm, and outer wall thickness is 56.21mm
Described retainer structure is embedded lock-fit-type structure;
Described seal ring can guarantee that bearing inside can bear 3 ~ 4 barometric pressure.
Adaptation coefficient between described rolling element and the raceway is 0.05 ~ 0.1.
In order to improve the lubricated and heat radiation of bearing, adopt retainer pocket hole to have oil storage and the Oil Guide mode of the multiple location of cone structure.
Beneficial effect of the present invention is: bearing cross section and outer ring wall thickness compared with normal roller bearing be thick to be gone out manyly, makes it can bear larger radial load.Retainer adopts unique embedded lock-fit-type structure, so that this bearing is easy to lubricate, installation and removal, and has saved manufacture cost.Adopt unique sealing configuration, make the inner mineralization pressure of bearing chamber, effectively guaranteed the pressure requirement of bearing lubrication system, and improved the lubricating condition of bearing; In addition, this bearing Proper Match the adaptation between rolling element and the raceway, and increased rolling element quantity, so that this bearing more can adapt to the bad working environments of high-mechanic, high rotating speed, high temperature.In addition, this airframe bearing has been broken traditional mounting type, adopts the way of packing into from the retainer internal diameter, thereby cancelled the filling slot of bearing outer ring, reduce the stress of bearing outer ring and concentrated, increased bearing outer ring intensity, effectively overcome the whole entire crack of bearing outer ring.
