The eccentric rolling transmission consists of rolling bearings mounted eccentrically on the input shaft, cooperating with cam wheels, which are mounted on the output shaft. The aim of this paper was to determine the sensitivity of the transmission to the manufacturing errors of the cam wheel. Two methods of cam wheels milling using a universal CNC machining center were proposed. The measurements of manufactured wheels were performed using a blue light 3D scanner, which allowed the determination of geometric dimensions and deviations from nominal geometry. The experimental research of the eccentric rolling transmission prototype equipped with manufactured cam wheels was conducted, measuring the torque on the gear shafts as a function of its angular position. On the basis of the obtained results, the impact of manufacturing errors on the operation of the transmission unit was examined, especially in terms of torque and efficiency. It was indicated that the machining using ball nose end mill ensures sufficient accuracy of the cam wheels.

“…The subject of this article is a new kind of mechanical transmissionthe eccentric rolling transmission (ERT) [1]. In previous studies, its geometry and kinematics [2] as well as the influence of technological inaccuracies on contact stress values have been analysed and simulated [3]. The aim of this article is to present the theoretical basis as well as the analytical and simulation models for the calculation of contact stresses on the surfaces of active components of the ERT.…”

The aim of the article is to present an analytical and a simulation model for the determination of the contact stresses in the eccentric rolling transmission. The stresses within the contact area of the eccentric unit and the cam wheel were analysed in accordance with the Hertz theory. 2D and 3D models for the finite element method (FEM) analysis were developed and the simulation results were compared with those of theoretical analyses. The influence of the eccentricity value and the dimensions of the bearing in the eccentric unit on the maximum and average values of contact stresses were investigated. The conducted research showed that, due to the contact stresses, it is advantageous to choose the bearing with the largest possible width and smallest outside diameter, and to apply low eccentricity values.
