Cycloidal gear is characterized by [2]: – Large ratio (up to 171:1) from one stage of reduction, which minimizes the weight and dimensions of the reducer. – Minimizing the centrifugal forces as the only high-speed element is the input shaft with an eccentric bearing. – Minimizing internal clearance due to simultaneous meshing of a large number of teeth. In contrast to gears with involute teeth, 10-50% of teeth are found in cycloidal gears with simultaneous meshing. It depends on the size of the gear and the load. The minimum number of teeth engages when running in bulk. – Low noise and low vibration for large torques and variable speeds. – High efficiency in a wide range of loads, because rolling elements are used in every place responsible for the transfer of torque. – Permissible load up to 500% of the rated torque. All above mention point lead into long-term and trouble-free operation, however the above features require high accuracy. The article described comparison of efficiency, vibration and noise obtained for 3 cycloidal gear modules: 1. Two-disc gear with single rollers for both discs (Chmurawa prototype [1]). 2. Three-disc gearbox with separate rollers for each disc (new idea) with gear components: output shaft with pins, housing with rollers (wheel with internal tooting), and input shaft, made with the manual lathe. 3. The same three-disc gearbox with output shaft with pins made with the CNC. Different levels of accuracy and thus corresponding vibration patterns were obtained.
