Problems solved by technology

For example, in Document 6, UG software is used to simulate the cutting motion, and the shaving cutter body is cut back through the inner ring gear body. Radial shaving is also a kind of internal meshing line contact processing technology, so the tooth surface of the shaving cutter cut out is actually The meshing line in the involute helical surface contacts the conjugate surface, the smaller the division of the simulated cutting motion, the higher the solution accuracy, but the slower the solution speed, the solved conjugate surface is connected by small grooves, not continuous smooth surface, and the conjugate surface data is located on the solid model, which needs to be further extracted, which is not conducive to the rapid design of cutting tools and grinding tools

Embodiment 2

[0185] Compared with Embodiment 1, the only difference is that it also includes a clamping power supply device, an AD conversion module and a processing module (in this embodiment, the processing module is a stc12c5a60s2 single-chip microcomputer, which has a 16-bit AD conversion module. The accuracy can reach 5 / 255V. After testing, it has been able to detect the deformed tool. If you want to improve the accuracy, you can choose an AD conversion module with higher accuracy). And the circle defined by the center of the circle and the inner diameter is the upper inner diameter circle; the lower inner diameter circle is defined similarly, the surfaces of the upper inner diameter circle and the lower inner diameter circle are covered with an insulating film, and the clamping power supply device is clamped between the upper end surface and the lower inner diameter circle. On both sides of the end face, the clamping power supply device is in close contact with the upper end face and ...

Description

technical field [0001] The invention relates to the field of high-precision gear processing, in particular to an analysis method for contacting a conjugate surface of a meshing line in an involute helical surface and a curved surface gear cutting tool. Background technique [0002] Gear cutting is a high-efficiency and high-precision gear dry cutting technology. In the gear cutting process system, the gear cutting knife is the most important component. In recent years, preliminary results have been obtained in the research on the design of gear cutters, but the current design theory is not enough to solve the problems in production practice in a timely manner. [0003] For the involute helicoid tooth surface of cut teeth, the conjugate surface of the internal meshing line contact is not the theoretical involute helicoid, but a special curved surface. Efficiently solving the conjugate surface of the internal meshing line contact of the high-precision involute helical surfac...
