Description

Expansion device for compensating abrasion of rack

Technical Field

The utility model relates to the technical field of rack abrasion compensation equipment, in particular to an expansion device for compensating abrasion of a rack.

Background

In mechanical transmission, gear and rack transmission is a common transmission mode, under the conditions of high-speed motion and frequent forward and reverse transmission of the gear and the rack, abrasion can be generated between the gear and the rack, so that a gap is generated by meshing the gear and the rack, the meshing gap of the gear and the rack directly influences the service life of the gear and the rack and the transmission stability, noise is easily generated in the meshing transmission process of the gear and the rack, the transmission stability is reduced, and therefore the problems of vibration, reduction of transmission efficiency, tooth surface failure and the like are caused, and the processing precision of machine equipment is further influenced.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems, the utility model provides an expansion device for compensating the abrasion of a rack, which solves the problem that a gap is generated due to the easy abrasion of a gear and the rack.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a tight device expands for compensating rack wearing and tearing, is including the part of placing that is used for placing the rack, be equipped with the standing groove on the part of placing, one side that standing groove and rack are relative all is equipped with a plurality of evenly distributed's connecting hole, be equipped with the concave ring on the connecting hole, be equipped with the round pin axle in the connecting hole, be equipped with the elastic component in the concave ring, rack upper end and lower extreme all are equipped with the slider, the standing groove inner wall be equipped with the spout that the slider corresponds.

Preferably, the length of the elastic part is more than 2 times of the width of the concave ring.

Preferably, the elastic member is a spring or a disc spring.

Preferably, the placing component further comprises a fixing block.

Preferably, the sliding block is made of rubber.

The utility model has the beneficial effects that: according to the expansion device for compensating the abrasion of the rack, the placing part is additionally arranged on one side of the rack, so that the elastic part in the placing part always keeps pressure on the rack, a gap generated between the rack and the gear due to abrasion is avoided, the rack can be fully meshed with the gear, and the transmission stability is improved.
