Summary of the invention
The purpose of this utility model provides a kind of end face harmonic motor, does not need to install the rotation output that decelerator just can directly obtain low speed, and simple in structure, axial dimension is little, in light weight, inertia is little, response is fast, and the precision height, noise is low, efficient is high.
For achieving the above object, the utility model is by the following technical solutions: a kind of end face harmonic motor, it comprises that band edge face tooth is just taken turns, band edge face tooth flexbile gear, displacement amplifier, described displacement amplifier is made up of function telescopic material and elastic hinge lever, described function telescopic material is connected with the input of displacement amplifying mechanism, described displacement amplifying mechanism comprises matrix, at least one lever, the fulcrum of described lever is an elastic hinge, and the displacement input of lever is that elastic hinge connects.
Because the output displacement of function telescopic material is less, use its deficiency separately so that flexbile gear produces enough deflections, form the bigger displacement amplifier of displacement output so the utility model has designed by function telescopic material and rigid hinge lever displacement amplifying mechanism.
The displacement input of described lever, lever is the lever that forms behind the matrix upper cut, the displacement input of lever, and described fulcrum is the fulcrum that direct otch forms on matrix.
In the utility model, output shaft can be fixed with band edge face tooth flexbile gear, or just wheel is fixing with band edge face tooth.
