Abstract
This article is to the new worm bearing adjuster worm gear meshing theory research and the manufacture, is mainly take the fourth-order contact as the key point, establishes the natural tooth profile “functional” the mathematical model and the computational method. Structure higher order meshing datum worm bearing adjuster tooth profile. According to the tooth profile design higher order meshing conjugate worm gear worm bearing adjuster's cutting tool which calculates and processes the higher order meshing match wheel. “Cuts originally the differential geometry touches” the concept to apply in the tooth face contact analysis. Form the heavy load worm gear worm bearing adjuster's nature with the worm gear worm bearing adjuster profiling principle and the higher order contact principle (stable state) the tooth profile one whole set theory, the method and realize. Produces two higher order contact worm gear worm bearing adjuster processing bit and processes two higher order contact worm gear worm bearing adjuster. And using VB procedure compilation, thus carries on the coordinated conjugate tooth profile's plan, as well as compilation datum worm bearing adjuster's coordinate data. Finally found one design method, enabled the worm gear worm toothing surface to obtain the high contact exponent number (to contact as far as possible as far as possible is closer, but incomplete fitting), enhanced its contact intensity and the lubrication effect. Finally will calculate in the School-operated workshop processing the worm gear worm bearing adjuster processes.
