The cam profile of the wave generator shall conform to the adopted meshing geometric relationship and ensure the required transmission properties. However, due to technological difficulties, it is often impossible to manufacture cams with arbitrary contour shape with required accuracy, although in principle, it is reasonable to develop equipment for machining cams with any contour shape, or to select and manufacture such equipment for specialized production of waveform reducer. Therefore, solving the opposite task has aroused special interest; That is, the process conditions and the meshing elements of the comprehensive waveform drive HD flexspline deformation harmonic device fha-25c-160-e250-c required by the contour shape of the generator cam shall be considered when selecting the adopted contour shape. According to this view, it is possible to make a wave generator without equipment to process the cam, which is feasible for any machinery manufacturing enterprise.
As an outline that may be provided in industry, it is obtained by some simple methods of epicycloid shape or long and short amplitude circular epicycloid shape. These contour shapes can be obtained by some simple methods.
When cam wave generator is used, the shape Zui stability of HD flexspline deformation harmonic device fha-25c-160-e250-c flexspline deformation is stable. At this time, the change of the initial deformation shape is possible only when there is clearance in the flexible bearing, contact deformation between the rolling element and the ring, and tension of the flexible wheel wall.
In the past, some data considered that the meshing of the transmission device allowed some interference at the tooth top. However, the experiments of these transmission and moving devices show that the interference of the design leads to the turbidity and blockage of the lubricating oil, and sometimes even the damage of the flexible bearing. In addition, when there is a working load, due to the deformation of parts and the reduction of clearance, the interference increases and the tooth top is stuck, which first causes the damage of the normal operation of the transmission device.
Because due to the manufacturing error of parts and the assembly error of transmission device, it starts to get stuck in one meshing area, rather than in all meshing areas at the same time, then the elastic deformation of parts forces the deformation of a wave to disappear. (that is, double wave transmission becomes single wave transmission, and three wave transmission becomes double wave transmission).
