二、小模數齒輪刀具的公差在齒輪製造过程中,控制齒輪刀具是控制齒輪和螺旋齒輪傳動質量的最有效措施之一。切削小模数齒輪时应侭先使用滾銑刀、插齒刀、及鉋齒刀。 (1)滾銑刀 滾銑刀本身是一个对銑刀軸线铣有ω角縱螺旋槽的單綫或多綫蝸桿。这个縱螺旋槽就構成了滾銑刀的切削面,其截面与齒条相近似(图三)。 Second, the small module gear tolerance In the gear manufacturing process, the control of gear cutting tool is to control the quality of gear and helical gear transmission one of the most effective measures. When cutting small modulus gears, you should use hob cutter, gear cutter, and gear cutter first. (1) hob cutter The hob itself is a single or multi-line worm screwed to the milling cutter axis ω longitudinal helical groove. The longitudinal helical groove forms the cutting face of the hob and has a section similar to that of the rack (Figure 3).
