Abstract:

This paper proposed a formation method of cycloid planetary drive with point contact and a general principle of point-contact conjugated meshing formed by the engagement pair of cycloid planetary drive was also presented. A new way of tooth surface constructed by the tubular enveloping surface was provided.The equations of the tubular surface and the contact curves were derived simultaneously. Based on this method and the theoretical derivations, the forming theory of the tubular conjugate tooth surfaces regarding the conjugate curve as the ridge line was established ultimately. An application for the cycloid planetary transmission was given, the helical tube tooth profile of cylindrical pin tooth was constructed and the selection methods applied in position parameter and the radial of mating tube were developed. The peculiarity of point-contact cycloid planetary drive was welso discussed subsequently. 

Key words: tubular tooth profile, point-contact, cycloid planetary transmission, teeth surface generation
