Description

Technical Field

[0001] The utility model relates to the technical field of flexible wheel processing, in particular to a flexible wheel processing tool for a harmonic reducer. Background Art

[0002] The flexspline of a harmonic reducer is a specially designed metal elastic element, usually in a drum or bowl shape, used in harmonic reducers.

[0003] The harmonic reducer is a high-precision, high-reduction ratio transmission device that uses the elastic deformation generated by the wave generator between the flexible wheel and the rigid wheel to achieve motion transmission.

[0004] The characteristics of the flexible wheel are its thin-wall structure and large elastic deformation capacity. During operation, the flexible wheel meshes with the rigid wheel to form multi-tooth contact, so that it can withstand large loads and transmit motion.

[0005] Due to the elastic properties of the flexible wheel, it can produce large deformation in one direction while maintaining relative rigidity in the other direction. This characteristic enables the harmonic reducer to achieve a large reduction ratio while also having high precision and stability.

[0006] The design and manufacture of the flexible wheel of the harmonic reducer involves expertise in many fields such as material science, mechanical analysis, and precision machining, so it has a crucial impact on the overall performance of the harmonic reducer.

[0007] At present, after the production of flexible splines, it is easy for tiny burrs and other uneven areas that are difficult to detect with the naked eye to appear on the tooth surface of the flexible spline. If this type of flexible spline is put into use directly, then under the continuous working environment of the reducer, the flexible spline and the steel wheel are likely to wear or mesh unstable due to the uneven areas, which will affect the durability of the reducer.
