In this paper, the equation of the projection of hob helicoid has also been deduced and the projection is compared with the basic rack nomal profile. 文中还求出了滚刀螺旋面的投影方程式，并与媒介齿条法面齿廓方程做了比较。
By way of a measuring face tageut with flauk profile andameasuring contact jigging along the tooth facem theminimundistance can be measured to show the batpitchdeviation. 利用一个与齿廓相切的测量面以及一沿齿面摆动的测量触头量得最小距离从而反映出基节偏差值。
Then, a theoretical foundation is established for gear generation with arbitary profile. 从而为范成法加工任意齿形的齿轮奠定了理论基础。
The shaving stock of preshaving gears has direct influence on the shaving effect and the tooth profile of preshaving cutters. 剃前齿轮的留剃量形式直接影响剃齿效果及剃前刀具齿形。
