Application of CVD diamond in diamond roller of worm gear grinding machine
Worm gear grinding machine is a continuous generating grinding machine for spur and helical cylindrical gears, which is suitable for batch and professional gear processing and production. The basic process is to use diamond rollers to dress the worm wheel, and then use the worm wheel to grind the gear. The grinding process has high requirements on the precision and service life of diamond rollers.
The principle of grinding gears of worm grinding wheel gear grinding machine is equivalent to the meshing principle of a pair of helical gears. The worm grinding wheel can be regarded as a helical gear with few teeth (the number of teeth of a single-head grinding wheel is equal to 1). Because of its small number of teeth, large helix angle and long teeth, it can make many turns around the axis, so it forms an involute worm whose normal base is equal to the normal base of the gear being ground. The meshing between the worm grinding wheel and the gear is regarded as the meshing between the processing gear and the imaginary rack formed by the worm grinding wheel along the normal section
