Problems solved by technology
At present, domestic double-wave harmonic reducers often use elliptical cam wave generators. Because elliptical cam wave generators have the advantages of convenient deformation control, small flexspline stress, and simple processing, they are widely used. Wave generators Better wave generators are less studied

The invention provides a design method of a sine wave generator, the sine wave generator and a storage medium, and belongs to the technical field of harmonic reducers. The problem that an existing harmonic reducer is insufficient in transmission performance is solved. The design method of the sine wave generator of the harmonic reducer comprises the steps that S1, the length Rta of a long half shaft of a sine wave cam is determined, and the radial deformation w0 and the base circle radius rm = Rta-w0 of the sine wave cam are initially determined; s2, establishing a sine wave cam curvilinear equation; S3, calculating the perimeter SZ of the inner side surface of the inner ring of the flexible bearing; S4, calculating the perimeter ST of a sine wave cam through a calculus method; s5, calculating the perimeter difference delta S = ST-SZ, and correcting the radial deformation w0 under the judgment condition that delta S is smaller than or equal to epsilon; s6, calculating the radius rm of the corrected base circle; and S7, drawing a final sine wave cam curve. The sine wave cam designed through the method can improve the transmission performance of the harmonic reducer.
Description
technical field [0001] The invention belongs to the technical field of harmonic reducers, and relates to a design method of a sine wave generator, a sine wave generator and a storage medium. Background technique [0002] The harmonic reducer is mainly composed of four basic components: a wave generator, a flexible gear, a flexible bearing and a rigid gear. Gear transmission to transmit motion and power. Flexible gears are referred to as flexible gears, and rigid gears are referred to as rigid gears. Usually, the rigid spline is fixed, and the wave generator is installed inside the flexible spline. When the wave generator rotates, the flexible spline is forced to continuously deform. The motion converts the input of the wave generator into the output of the flex spline to realize the reduction transmission. [0003] The wave generator is the component that controls the movement of the flexspline's teeth around the circumference. The curve shape of the wave generator determ...
