This paper proposes a simple approach on the synthesis of the 2D profiles for the rotors of cycloidal reducers. A 2D rotor (or cycloidal disc) profile (as a complex closed curve) can be defined (as an alternative to the strictly mathematical definiti

This paper intends to introduce a new approach in cycloidal reducers design. The usual design uses rotary pins as teeth on the ring gear (or stator as well) and an appropriate conjugate profile on the cycloidal disc (or rotor as well). This study pro

In general, the production of bearings is a very large series production, which is why in production the technological lines are designed to process a single size of bearings. Changing the production line for different types of bearings is expensive
