Abstract
The utility model discloses a spline-type elastic coupler which comprises a ring-shaped toothed cover made of an elastic material, and spline teeth formed on the inner circumference of the ring-shaped toothed cover; and which further comprises an input-side toothed ring and an output-side toothed ring, which engage with the ring-shaped toothed cover, and spline teeth formed on the input-side toothed ring and the output-side toothed ring and engaging with the spline teeth on the inner circumference of the ring-shaped toothed cover. The spline-type elastic coupler has the advantages of easy assembly and low noise.
Description
Technical field
The utility model belongs to mechanical type shaft coupling structure, is specifically related to motor shaft in the automobile electric booster steering system and the draw bail between the coupled axle.
Background technology
Mechanical coupling is of a great variety, be widely used, with a long history.Constantly improve along with the variation of engineering structure and development with to the requirement of coupler, the coupler of making of new material, new construction is also in the continuous appearance of Lu.
Between the motor shaft and worm shaft of automobile electric power-assisted steering, once extensively used splined, promptly male splines is made on the worm shaft, and female splines is made on the motor shaft.Though the size of itself is little, in light weight, simple in structure, cost is also low, also have radial missing and the exigent shortcoming of axial deviation that machine up is produced; Be difficult to eliminate the gear back lash that produces because of machine up or because of service wear; Can also bring a series of shortcomings such as work noise behind the flank generation gap.
Summary of the invention
At the above defective that exists in the prior art, it is a kind of easy to assembly that the utility model provides, and cooperates compactness and the little tooth-like elastic coupling of key of work noise.
The technical solution adopted in the utility model is as follows: the tooth-like elastic coupling of a kind of key, comprise an annular tooth cover of making of elastomeric material, the interior circle of annular tooth cover has been done the key tooth, also comprise the input end gear ring and the mouth gear ring that match with the annular tooth cover, input end gear ring and input end gear ring are provided with the key tooth that matches with round key tooth in the annular tooth cover.
The tooth-like elastic coupling of key of the present utility model, the elastomeric material that annular tooth is applied mechanically are elastomeric material.
The tooth-like elastic coupling of key of the present utility model, the interior round key tooth of annular tooth cover is an indent square key tooth.
The tooth-like elastic coupling of key of the present utility model, input end gear ring and mouth gear ring are separate piece, through compression fit to axle.
The tooth-like elastic coupling of key of the present utility model, two gear ring structures and measure-alike.
The utlity model has following advantage:
(1) install and use the tooth-like elastic coupling of key, so the radial missing that is not subjected to machine up during assembling and is produced and the influence of axial deviation are easy to assembly.
(2) install and use the tooth-like elastic coupling of key, can eliminate the gap that produces because of machine up or because of service wear.
(3) install and use the tooth-like elastic coupling of key, can eliminate work noise, this is to reducing the noise in the operator's compartment, and it is necessary to improve traveling comfort.
Description of drawings
Fig. 1 is the assembly drawing of the utility model embodiment;
Fig. 2 is the constructional drawing of the utility model embodiment constituent part;
Fig. 3 is the partial assembly drawing of the utility model embodiment.
The specific embodiment:
As shown in the figure, the tooth-like elastic coupling of the utility model key comprises motor shaft 1, input end gear ring 2, annular tooth cover 3, mouth gear ring 4 and axle 5.
Wherein the right-hand member of motor shaft 1 and axle 5 is an optical axis.The appearance of input end gear ring 2 and mouth gear ring 4 has been done some square key teeth, and input end gear ring 2 and mouth gear ring 4 are installed on motor shaft 1 and the axle 5 by endoporus, are interference fit between the two.Annular tooth cover 3 usefulness rubber are made, and do quantity and the identical interior square key tooth of the square key number of teeth on the gear ring in the internal diameter position, its size is then required to should be no gap between the interior external key tooth in assembling back but also will compress mutually.The length of annular tooth cover 3 is a bit larger tham the twice of the square key tine length on arbitrary gear ring at least.
The present embodiment working process is as follows with principle: connected motor shaft 1 and axle at 5 o'clock with the tooth-like elastic coupling of key, be to realize by the annular tooth cover made from rubber 3, therefore can be by its elastic reaction, radial missing that is produced when eliminating installation and manufacturing and axial deviation are to installing adverse influence.
In the time of machine operation, output power by motor shaft.Because of input gear ring 2 is an interference fit with motor shaft,, pass to axle 5 again so power can be delivered to annular tooth cover 3 through input gear ring 2.Because of annular tooth cover is Rubber Parts, be again around here, so can not produce noise transferring power the time by rectangle alligator on it and the rectangle alligator force fit on the gear ring.In case produce the gap between the inside and outside rectangle alligator, can utilize the elasticity of rubber and the mutual force fit of rectangle alligator, can eliminate the gap between the rectangle alligator again.
