Abstract
The utility model discloses an automatic aligning harmonic drive speed reducer which comprises a rigid gear, a flexible gear and a wave generator. The wave generator comprises a cam, a coupler, a cross-shaped slide block and a clamping ring. The coupler is arranged penetrating through the cam. The cross-shaped slide block is sleeved on the coupler. A protruding tooth is arranged on one end face of the cross-shaped slide block. A groove which is used for the protruding tooth to be inserted in and to slide in is arranged on one end face of the cam. The clamping ring is sleeved on the end portion of the coupler and is used for fixing the coupler. Compared with a traditional cam type harmonic drive speed reducer, the automatic aligning harmonic drive speed reducer is more accurate in positioning accuracy, and mounting error is convenient to adjust.
Description
Technical field
The utility model relates to a kind of harmonic wave drive speed reducer, particularly relates to a kind of self-aligning harmonic wave drive speed reducer.
Background technique
Existing self-aligning harmonic wave drive speed reducer is widely used in electronics industry, lathe, instrument and apparatus, printing packaging field.But the ride quality of existing self-aligning harmonic wave drive speed reducer is unstable and Location accuracy is inaccurate, needs to improve.
The model utility content
In view of the problems referred to above that prior art exists, the purpose of this utility model is to provide the self-aligning harmonic wave drive speed reducer of the stable and accurate positioning of a kind of ride quality.
To achieve these goals, a kind of self-aligning harmonic wave drive speed reducer that the utility model provides, comprise firm wheel, flexbile gear and wave-generator, wherein, described wave-generator comprises cam, coupling, crosshead shoe and collar, described coupling passes described cam setting, described crosshead shoe is sheathed on the described coupling, and be provided with protruding tooth on the end face of described crosshead shoe, be provided with the groove that enters wherein and can slide for described protruding eye cutting on the end face of described cam, the end that described collar is sheathed on described coupling is used for fixing described coupling.
As preferably, be provided with catch between described collar and the described cam.
As preferably, the radial clearance of described crosshead shoe and described coupling is 0.038mm-0.09mm.

Description of drawings
Fig. 1 is the structural representation of self-centering type harmonic wave drive speed reducer of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described in detail.
A kind of self-aligning harmonic wave drive speed reducer that the utility model provides, comprise firm wheel, flexbile gear and wave-generator, wherein, as shown in Figure 1, described wave-generator comprises cam 3, coupling 1, crosshead shoe 2 and collar 5, described coupling 1 passes described cam 3 and arranges, described crosshead shoe 2 is sheathed on the described coupling 1, and be provided with protruding tooth 21 on the end face of described crosshead shoe 2, be provided with the groove 31 that inserts wherein and can slide for described protruding tooth 21 on the end face of described cam 3, the end that described collar 5 is sheathed on described coupling 1 is used for fixing described coupling 1.
In the utility model, because protruding tooth 21 can slide in groove 31, install and the relative displacement between input shaft and output shaft (not shown) during running so can compensate.Can when transmission, effectively avoid like this stress to concentrate, increase the service life, simultaneously can also compensate and correct by install caused radially, axially, the deviation of angle. have need not to lubricate, compact structure, the advantage such as lightweight, and can effectively improve and absorb the impact that the inhomogeneous transmission of driving arrangement produces, thereby improve the ride quality of machinery, improve machine operation stability.In the utility model, the distance between described crosshead shoe 2 and the described coupling 1 also is important parameter, and as preferably, described crosshead shoe 2 is 0.038mm-0.09mm with the radial clearance of described coupling 1.
In addition, in the present embodiment, as preferably, between described collar 5 and described cam 3, be provided with catch 4, can play better fixation like this.
And as preferably, the axial clearance in described coupling 1, crosshead shoe 2, cam 3, catch 4 and the collar 5 between adjacent two parts is 0.15mm-0.2mm.
Above embodiment is exemplary embodiment of the present utility model only, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the utility model in essence of the present utility model and protection domain, this modification or be equal to replacement and also should be considered as dropping in the protection domain of the present utility model.
