Description

Round nut

Technical Field

The utility model relates to a nut, in particular to round nut.

Background

The round nut is usually matched with the round nut by a stop washer, and when the round nut is assembled, the inner tongue of the washer is inserted into the groove on the shaft, and the outer tongue of the washer is embedded into the groove of the round nut, so that the nut is locked; or double nuts are adopted for preventing looseness. Often as axial fixation of the rolling bearing.

The existing round nut is not stable in connection and has larger noise due to the fact that the existing round nut is loosened with a shaft when being vibrated or rotated by the shaft.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a round nut to solve above-mentioned problem.

The technical scheme of the utility model is realized like this: the utility model provides a round nut, includes nut body and locking ring, the locking ring is established in one of nut body outer wall and is served, be equipped with the screw thread on the inner wall of nut body, be equipped with a plurality of breachs on the lateral wall of locking ring, be equipped with the holding tank on the inner wall of nut body, be equipped with the latch segment in the holding tank, run through on the lateral wall of nut body and be equipped with the screw hole with the holding tank intercommunication, screw hole female connection has interior hexagonal screw, interior hexagonal screw is contradicted with the latch segment and is connected, one side that interior hexagonal screw was kept away from to the latch segment is established to the arc corresponding with nut body inner wall, be equipped with the arc recess on the inner wall of nut body, the embedded sealing.

By adopting the technical scheme, after the round nut is sleeved on the shaft, the round nut pushes the locking block by rotating the inner hexagonal screw, so that the locking block is tightly attached to the shaft, the connection stability is effectively improved, and the round nut is not easy to shake; the seal ring further improves the connection stability between the seal ring and the shaft.

The utility model discloses further set up to: the holding tank is equipped with two at least and keeps away from the setting each other.

Through adopting above-mentioned technical scheme, intensity and stability that can effectual improvement is connected make being connected between round nut and the axle more firm.

The utility model discloses further set up to: the notches are uniformly arranged around the axis line of the anti-loosening ring in an annular mode, and at least four notches are arranged.

Through adopting above-mentioned technical scheme, make round nut's locking effect better, make its stability more.

The utility model discloses further set up to: and an inclined chamfer is arranged at the edge of the upper side face of the anti-loosening ring.

By adopting the technical scheme, the installation of the round nut is more convenient and easier.

The utility model discloses further set up to: the nut body and the anti-loosening ring are integrally formed.

By adopting the technical scheme, the connecting strength is effectively improved, and the service life is prolonged.
