Dynamics Analysis of Spatial Parallel Mechanism with Irregular Spherical Joint Clearance
Shock and Vibration, 2019 Clearances caused by machining accuracy and assembly requirements are regular, but they will be irregular due to the wear of the kinematic pairs. At present, there are few studies on wear of space kinematic pairs.

Effect of Bearing Clearance on Cardan-Joint Kinematics
15th Design Automation Conference: Volume 3 — Mechanical Systems Analysis, Design and Simulation, 1989 Abstract The effect of radial bearing clearance at the intermediate joints of a Cardan-type universal joint has been investigated. It is found that errors in displacement at the output and also intermediate joints occur, and that their amplitudes have a linear relationship to the magnitudes of the radial bearing clearances.

Dynamics of Multibody Systems With Spherical Clearance Joints [PDF]
Journal of Computational and Nonlinear Dynamics, 2005 This work deals with a methodology to assess the influence of the spherical clearance joints in spatial multibody systems. The methodology is based on the Cartesian coordinates, with the dynamics of the joint elements modeled as impacting bodies and controlled by contact forces. The impacts and contacts are described by a continuous contact force model
