Design of Tooth Profile of Cycloid Cam Outer Generator Swinging Teeth Drive by Yi Yali, Dou Linrui, Jin Herong, Zhang Wenchao

“…In order to realize the outer generator swinging rod teeth drive steadily transmit with high transmission ratio and heavy load,the cycloid curve with a continuous derivative curve till third order and the character of no rigid or no flexible impact is adopted as the tooth profile of outer generator cam. The plural-rectangular coordinate system is established,the outer generator cam teeth profile is designed with the method of plural vector,then the theory and the actual teeth profile equations of center gear are derived based on speed conversion principle and envelop theory. …”

Tooth Contact Analysis of Profile-Shifted Face Gear with Double-Crowned Pinion by Li Wei, Wang Dan, Fu Xuezhong

“…The coordinate systems for the processing and driving of the profile-shifted spur pinion with double-crowned and the profile-shifted face gear are established,the tooth surface equations of the profile-shifted pinion and the profile-shifted face gear are deduced,while the tooth surface is simulated for visualization.The modified tooth surface is precisely represented by a sum of two vector functions that determine the theoretical tooth surface and deviation surface.The tooth contact analysis is conducted for the alignment errors of the driving system,and the tooth contact path and the transmission error are computed.The results show that it enables the transmission error to form second order parabolic function with opening down through this method,the sensitivity of contact patch for the alignment errors is reduced,and the meshing performance of profile-shifted face gear drive is improved.…”
