Background technique
The existing conventional crown gear coupling generally all is made up of an external gear axle sleeve and a ring gear at present, can be by the engagement transmitting torque of crowned teeth.When external gear axle sleeve and ring gear generation relative angular displacement, crowned teeth and gear teeth generation EDGE CONTACT are improved the uniformity that the Surface of action upward pressure distributes, and play the effect of compensation drive line angular displacement.
But also there are the following problems for existing conventional crown gear coupling, and its ring gear and external gear axle sleeve can move to axial, and this makes it can't transmit end thrust, and can't apply to needs to transmit in the drive line of end thrust.
The utility model then provides a kind of crown gear coupling of the end thrust transmitted newly in order to improve or to solve the above problems.
The model utility content
In order to overcome the deficiency that conventional crown gear coupling in the existing industry can't transmit end thrust, the technical problem that the utility model solves provides a kind of crown gear coupling of the end thrust transmitted newly, it has characteristics such as compact structure, transmitting torque scope be wider, can adapt under abominable operating mode and work.
The utility model solves above-mentioned technical problem by such technological scheme: a kind of crown gear coupling that transmits end thrust, comprise transmission shaft, coupling location expansion set and locating flange, the described crown gear coupling that transmits end thrust also comprises the crown gear coupling be made up of an internal gear half-coupling and external gear half-coupling and one by two thrust articulated bearings and the bearing pack that plain radial bearing is formed, and the axial position at described bearing pack center is consistent with the axial position at described crown gear coupling center.
Further, an end of described external gear half-coupling is connected with locating flange by bolt.
Further, the other end of described external gear half-coupling is connected with the internal gear half-coupling, forms a crown gear coupling.
Further, described driving sleeve is connected in the internal gear half-coupling, and is rigidly connected by coupling location expansion set and internal gear half-coupling.
Further, described two thrust articulated bearings are encircled the bearing pack of both sides composition that is installed in plain radial bearing.
Further, the described bearing pack of being made up of two thrust articulated bearings and plain radial bearing is arranged in the crown gear coupling.
Further, fixedly connected with the external gear half-coupling in the outer ring of described bearing pack, and its inner ring is connected with the end of transmission shaft.
Further, the engagement of described crown gear coupling transmission gear is a crown-shaved gear.
Further, the described crown gear coupling that transmits end thrust also comprises first setting sleeve and second setting sleeve, and described first setting sleeve and second setting sleeve are arranged in the crown gear coupling, and between locating flange and bearing pack.
Compared with prior art; the utlity model has following advantage: the crown gear coupling of a kind of end thrust transmitted newly of the utility model has solved the deficiency that conventional crown gear coupling can't transmit end thrust; both but compensating shaft was displacement; play the effect of protection axle system, can transmit end thrust again.
Description of drawings
Fig. 1 is and a kind of crown gear coupling sectional view that transmits end thrust of the utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Please refer to Fig. 1, the utility model provides a kind of crown gear coupling 10 that transmits end thrust, it mainly includes transmission shaft 101, coupling location expansion set 102, internal gear half-coupling 103, rubber seal leather cup 104, external gear half-coupling 105, locating flange 106, the first setting sleeves 107 and second setting sleeve 108, and the bearing pack of forming by first thrust articulated bearing 109, plain radial bearing 110 and second thrust articulated bearing 111.
