THE ROLE OF TRAJECTORY IN THE FUNCTION OF RESEARCH PTO TRANSMISSIONS


Dragisa Micic, Zorica Lazic

Abstract: In this paper, the kinematics of the motion of an inner moving circle along a twice as large fixed outer circle will be considered. Such circles are known in science as Cardan circles. Specifically, within this topic of the paper, cases will be presented where when rolling a small cardan circle within a large cardan circle, all points along the circumference of the small cardan circle will describe straight lines, which correspond to the diameter of the large cardan circle in length and position. Particular attention is paid to the determination of the turning circle as well as all other kinematic parameters in four-member transmissions.
