The CSG-32-80-2UH harmonic drive is designed to transfer mechanical motion using a constructed, controllable hamonaker elastic deformation. Harmonic drive is usually composed of three basic components, including a rigid wheel with inner teeth, a flexible wheel with outer teeth that can produce radial elastic deformation when working, and a wave generator installed in the flexible wheel internal transmission part wave, oval shape, with flexible rolling bearings in the outer ring. The number of external teeth of flexible wheel is less than the number of internal teeth of rigid wheel. When the wave generator rotates, the outer teeth of the flexible wheel corresponding to the long axis direction just completely engage the inner teeth of the rigid wheel
In order to ensure the correct design of small module gear, as well as the economical and effective production and use, China has formulated a series of national standards related to small chess gear, such as reference tooth profile, Hamenaco precision mechanical unit harmonic drive CSG-32-80-2UH modulus and precision, etc. The implementation of these standards plays an important role in ensuring the interchangeability of small module gear production, and raises the design and manufacturing level of small module gear in China to a new height.
The gear backlash is usually reflected in the positive and negative rotation of the harmonic drive CSG-32-80-2UH hamenaco precision mechanical unit. Therefore, the national standard uses the circumferential backlash instead of the normal backlash in the machine standard. This will bring some convenience to the calculation of return error in transmission.
However, in production practice, the selection of tooth profile curve must not only satisfy the basic law of tooth profile engagement, but also take into account the requirements of manufacturing, installation and strength. In precision machinery and instruments, Hamenaco precision machinery unit harmonic drive CSG-32-80-2UH usually uses two kinds of involute tooth profile and cycloid tooth profile, especially the involute tooth profile is the most widely used.
In the design and manufacture of precision mechanical instruments, if the modified gear is used and the appropriate modified coefficient is selected, better comprehensive quality index can be obtained than the standard gear. Hamenaco precision mechanical unit harmonic drive CSG-32-80-2UH can improve the meshing performance (contact degree, slip rate, etc.).
Their main disadvantages are :(1) there is no interchangeability, the hamenaco precision mechanical unit harmonic drive csg-32-80-2uh must be designed, built and used in pairs, and (2) there is a slight reduction in overlap.
