Influence of the Geometrical Design on Ball and Crossed Roller Wire Race Bearing Behavior under Axial Load

Abstract

Wire bearings are becoming popular these days in applications such as defence, robotics, medical devices or shipping industry. They provide weight and inertia reductions, good shock load and vibration absorbing capacity, constant torque and low maintenance. Despite all the benefits of this kind of bearings, there are few wire race bearing manufacturers, which own the design and manufacturing know-how. This work is focused on providing some design guidelines for ball and crossed roller wire race bearings established upon different geometrical parameters, by means of a DoE performed with Finite Element simulations. The results of the simulations are carefully compared to obtain the effects of those geometrical parameters in several performance indicators.
