Description

Helical ring bearing locking structure

Technical field

This utility model belongs to locking mechanism field, more particularly, to a kind of helical ring bearing locking structure.

Background technology

In recent years, with the fast development of China's economy, the level of consumption of the people is improved constantly, and has been greatly facilitated civilian building Build, the industry such as automobile, skyscraper, railroad bridge flourish.Requirement to shaped steel product is also just more and more, more Product specification, more preferable production assurance are also just more and more stricter.As the capital equipment in whole piece type steel production line, roll The performance of machine directly affects product quality, and roller system as the important component part of milling train, in the operation of rolling, bearing Very big roll-force is produced during transmission steel rolling, and bears roll and produce axial motion power.Bearing is produced to bear roll during steel rolling Raw axial force, prevents roll axial motion, it is necessary to carry out axial locking to bearing.Herein axial locking structure is changed It is kind, coupling mechanism force is improve, locking effect more preferably, is hardly damaged, is set forth explanation.

The content of the invention

In view of this, this utility model is directed to a kind of helical ring bearing locking structure, can solve the above problems.

To reach above-mentioned purpose, what the technical solution of the utility model was realized in：

A kind of helical ring bearing locking structure, including the bearing, spacer ring being sheathed on successively on the outside of roll from left to right, first Helical ring, the second helical ring and grafting ring, mutually lock between first helical ring and the second helical ring, the first helical ring End is fixed by screw, withstands spacer ring, and grafting ring is held out against in the end of the second helical ring,

The bearing is fixed on bearing block, is fixed with connecting seat, is provided with gland on the outside of the second helical ring on the outside of spacer ring, It is bolted between gland, connecting seat and bearing block, connecting seat is bolted on bearing block, gland is solid by bolt It is scheduled on connecting seat.

Further, the gland includes the first gland and the second gland, the first gland be located at connecting seat and the second gland it Between, sealing gasket is provided between the first gland and the second gland, the second gland is fixed on the first gland, and top tight sealing by screw Pad.

Further, the grafting ring includes two semi-rings being mutually inserted.

Relative to prior art, helical ring bearing locking structure described in the utility model has following advantage：This structure is leaned on Helix face is locked, and instead of original screw-threaded coupling, and locking effect is more preferable, it is to avoid screw thread covers dead phenomenon, and coupling mechanism force is bigger, Roll axial restraint is ensure that, being effectively prevented larger axial force causes original screw-type locking mechanism generation screw thread to be covered Extremely, thread failure, the problems such as coupling mechanism force is inadequate, as screw-threaded coupling fails during so as to causing roll to change, generation cannot be more Changing roll, damage parts maintenance affects the problem of production.
