Description

Triangular tooth spline

Technical Field

The utility model relates to a spline specifically is a triangle tooth spline.

Background

The spline coupling consists of an internal spline and an external spline. The inner spline and the outer spline are both multi-tooth parts, the spline on the inner cylindrical surface is an inner spline, and the spline on the outer cylindrical surface is an outer spline. Obviously, a spline coupling is a development in the number of flat key couplings.

Some existing triangular tooth splines mostly exist in an integral mode, the spline needs to be integrally replaced by disassembling the spline if excessive abrasion occurs to the triangular tooth after long-time use, operation is inconvenient, and certain resources are wasted. Therefore, we improve this and propose a triangular spline.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model relates to a triangular teeth spline, including triangular teeth spline body, triangular teeth spline body includes inner tube and overcoat, the inner tube cooperatees and sets up in the overcoat, just the outer wall of inner tube is provided with a plurality of fixture block, a plurality of along the fixed a plurality of fixture block, a plurality of the fixture block cooperatees respectively and sets up in the draw-in groove of seting up at the overcoat inner wall, just the outside of overcoat is provided with carries out the fixing bolt fixed to the position of inner tube.

As a preferred technical scheme of the utility model, the ring channel has been seted up along the circumferencial direction to the outer wall of overcoat, be provided with a plurality of fixing bolt along the circumferencial direction in the ring channel respectively.

As a preferred technical scheme of the utility model, a plurality of corresponding screw hole of offering with fixing bolt matched with a plurality of fixing bolt on the fixture block respectively.

As a preferred technical scheme of the utility model, the fixed mounting flange that is provided with of one end of overcoat, a plurality of mounting hole has been seted up along the circumferencial direction to mounting flange's terminal surface.

As an optimal technical scheme of the utility model, the inner wall of inner tube is provided with a plurality of triangle tooth, a plurality of the triangle tooth distributes along the circumferencial direction equidistance respectively.

The utility model has the advantages that: this kind of triangular tooth spline: cooperate with the draw-in groove through the fixture block and place the inner tube is spacing in the overcoat, then cooperate with the screw hole through fixing bolt and be connected, can be with the fixed setting of inner tube in the overcoat, after excessive wearing and tearing appear in the long-time use of the triangle tooth in the inner tube, fixing bolt that can become flexible shifts out the inner tube and changes can, operate comparatively convenient and fast, and need not carry out the whole change to triangle tooth spline body, can reduce the waste of resource.
