Abstract
The utility model provides a shaft sleeve axial fixing structure. The shaft sleeve axial fixing structure comprises an output shaft provided with an external spline and an internal spline sleeve provided with a torque output end, and torque is transmitted between the output shaft and the internal spline sleeve through spline fit. The shaft sleeve axial fixing structure further comprises a casing pipe provided with internal taper threads, external taper threads are arranged on the internal spline sleeve, the casing pipe and the internal spline sleeve are screwed up through the internal taper threads and the external taper threads so that the internal spline sleeve can deform, and therefore the external spline of the output shaft and an internal spline of the internal spline sleeve are clamped. The shaft sleeve axial fixing structure can ensure concentricity of the output shaft and the internal spline sleeve, and is reliable in connection.
Description
Technical field
The utility model relates to shaft drive field, is specifically related to a kind of axle sleeve axial fixing structure.
Background technique
Existing cantilevered axle, such as motor output shaft, is generally external splines or flat key, at moment of torsion output terminal, while being also unsettled, in experiment, just needs a switching device.Traditional method is to do an inner spline housing, coordinates with motor external splines, and because motor is fixed, motor external splines is substantially also fixed, but inner spline housing can endwisely slip, extra vibration while causing electric machine rotation.Traditional method is to open radial bolts hole at inner spline housing, with bolt, spline is withstood, but this easily by inner spline housing top partially, causes concentricity poor, and during high rotating speed, abnormal sound even ruptures, and causes danger.Meanwhile, while moving due to motor, spline has vibration, is used for the bolt of poppyhead key in this operating mode lower end surface, can wear and tear for a long time, will be ineffective after working long hours.
Model utility content
The purpose of this utility model is to address the above problem, and provides a kind of and can guarantee output shaft with inner spline housing concentricity and be connected reliable axle sleeve axial fixing structure.
For achieving the above object, the utility model provides following technological scheme:
An axial fixing structure, comprising: output shaft, and it has external splines; The inner spline housing with moment of torsion output terminal; Described output shaft and described inner spline housing are by spline fitted transmitting torque, also comprise the sleeve pipe with inside tapered thread, on described inner spline housing, there is outer cone thread, described sleeve pipe and described inner spline housing make described inner spline housing produce distortion by screwing of inside and outside tapered thread, thereby the external splines of described output shaft and the internal spline of described inner spline housing are clamped.
Preferably, on described inner spline housing, there is axially open.
Preferably, on described sleeve pipe, there is radial bolts hole.
The beneficial effects of the utility model are:
Thereby the screwing of inside and outside tapered thread by sleeve pipe and inner spline housing makes inner spline housing distortion clamp external splines, therefore the distortion of inner spline housing is relatively uniform, can be because bolt poppyhead key makes inner spline housing eccentric, guarantee the concentricity of output shaft and inner spline housing, reduced the abnormal sound that High Rotation Speed brings, risk of breakage.
Further, the axially open on inner spline housing makes inner spline housing more yielding, correspondingly, screws the required power of sleeve pipe less, installs easier.
Further, radial bolts hole on sleeve pipe can be screwed into bolt and hold out against inner spline housing, force the engagement of the inside tapered thread of sleeve pipe and the outer cone thread of inner spline housing tighter, thereby the compressing internal spline of inner spline housing and the external splines of output shaft further clamp, and prevent that sleeve pipe from skidding and come off.From the above, bolt not immediate roof, on external splines, but evenly clamps external splines by the transitional function of sleeve pipe, can not cause bias, also can not lose efficacy because of wearing and tearing.
Accompanying drawing explanation
Next in connection with accompanying drawing, specific embodiment of the utility model is described in further detail, wherein:
Fig. 1 is embodiment's of the present utility model structural representation;
Fig. 2 is the structural representation of embodiment's of the present utility model inner spline housing;
Fig. 3 is the structural representation of embodiment's of the present utility model sleeve pipe.
Description of symbols in upper figure:
Output shaft 1, sleeve pipe 2, inner spline housing 3, bolt hole 21, inside tapered thread 22, moment of torsion output terminal 31, outer cone thread 32, internal spline 33, opening 34.
Embodiment
In conjunction with Fig. 1 to Fig. 3.Output shaft 1 has external splines (unmarked), and it is outwards exported the moment of torsion that comes from power source (for example motor).Inner spline housing 3 has moment of torsion output terminal 31, for to the moment of torsion that comes from output shaft 1 is outwards exported.The internal spline 33 of inner spline housing 3 coordinates with transmitting torque with the external splines of output shaft 1.Inner spline housing 3 also has outer cone thread 32, and sleeve pipe 2 has inside tapered thread 22.During installation, inner spline housing 3 is screwed in to sleeve pipe 2, outer cone thread 32 coordinates with inside tapered thread 22, then output shaft 1 being inserted to inner spline housing 3 makes after inside and outside spline fitted, screw sleeve pipe 2, due to the interaction between inside and outside tapered thread, inner spline housing 3 produces distortion, thereby the external splines of output shaft 1 and the internal spline of inner spline housing 3 33 are clamped.And this clamping process is evenly carried out along with screwing sleeve pipe 2, there will not be eccentricity issues.As preferably, on inner spline housing 3, also there is axially open 34, make in screwing the process of sleeve pipe 2, inner spline housing 3 more easily produces distortion, and required to screw moment of torsion less, installs more convenient.As preferably, on sleeve pipe 2, there is radial bolts hole 21, screw after sleeve pipe 2, in bolt hole 21, be screwed into bolt (not shown), bolt can force between inside and outside tapered thread 22,32 and further compress, thereby makes to block tightlyer between internal spline 33, external splines, and prevents that sleeve pipe 2 from coming off.And bolt is to withstand on the outer surface of inner spline housing 3 but not withstand on the external splines of output shaft, so the end face of bolt can not lose efficacy owing to producing vibration abrasion with external splines.
Although the utility model is described in conjunction with above embodiment; but the utility model is not defined to above-described embodiment; those of ordinary skills can easily carry out equivalence to it and replace and modification, but do not leave the protection domain of claim of the present utility model.
