Chinese Journal of Mechanical Engineering, 2023 The existence of the relative radial and axial movements of a revolute joint’s journal and bearing is widely known. The three-dimensional (3D) revolute joint model considers relative radial and axial clearances; therefore, the freedoms of motion and ...

International Journal of Aerospace Engineering, 2020 Clearances in the joints of real mechanisms are unavoidable due to assemblage, manufacturing errors, and wear. The dual-axis driving and positioning mechanism is one kind of space actuating mechanism for satellite antenna to implement precise guidance ...

Error estimation and compensation in 4R and P3R closed-chain mechanisms due to joint clearance: a comparative study [PDF]
Scientific ReportsFour-bar linkages form the fundamental configuration of many planar mechanisms, and joint clearance is one of the primary factors that introduce deviations from their intended output. This paper presents a performance assessment of planar mechanisms with

A continuous contact force model of planar revolute joint based on fitting method
Advances in Mechanical Engineering, 2017 Both the process of eliminating the clearance in joints and the contact–impact process involve movement of a clearance mechanism, which may reduce transmission accuracy and lengthen the response time. An appropriate continuous contact force model is able

Contact Model of Revolute Joint with Clearance Based on Fractal Theory
Chinese Journal of Mechanical Engineering, 2018 The contact stiffness of a mechanical bonding surface is an important parameter in determining the normal and radial contact force. To improve the calculation accuracy of the contact force model, the surface roughness of the bonding surface and the ...

3D Revolute Joint with Clearance in Multibody Systems [PDF]
, 2017 The aim of this paper is to understand the influence of radial and axial clearance in the revolute joints on the overall performance of a circuit breaker. A circuit breaker mechanism is made of seven links, seven revolute joints with clearance in both radial and axial direction, four unilateral contacts with friction, and it has forty-two degrees of ...

Lead-Screw-Driven Revolute Joint for Use in the Remote Center of Motion Mechanism
IEEE Access, 2022 The revolute joint of the remote center of motion (RCM) mechanism should be operated within a limited rotation range to ensure patient safety. To achieve this with the conventional revolute joint, the rotation range was limited with the use of software ...
