A Study of the Influence of the Bearing’s Flexibility on the Operation of a Cycloidal Gear Drive

The paper presents a study of the influence of the bearing’s flexibility on the operation of a cycloidal gear drive and highlights the importance of taking the bearing’s flexibility into account when performing calculations. It shows how flexibility affects force distribution across the pins and the displacement of the most loaded pin from the pitch point towards the gear’s axis of symmetry. A method of force calculation for the KHV and 2KV type gears taking into account the bearing’s flexibility is considered. Schematic diagrams of force distribution across the pins with and without taking the bearing’s flexibility into account are presented for two types of gearing. An experiment is performed that confirms the necessity of taking the bearing’s flexibility into account. The applicability of the method for calculating various types of cycloidal gear drives is analyzed.
