Force analysis of universal joint shaft of ship cross axle

The force situation of the shaft bearing installed in the ship cross axle universal joint is complex due to the influence of the cross axle universal joint. This paper briefly analyzes the mechanical properties and speed characteristics, as well as the force of the cross axle universal joint. On this basis, the radial load of each shaft bearing in the ship cross axle universal joint under various circumstances are calculated through the balance equation and three bending moment equations by using MATLAB and EXCEL. Finally, it briefly discusses the calculation method of the axial force on the cross axle universal joint, and the influence of the force on the shaft bearing, which can provide theoretical basis for the design, construction and maintenance of the shaft of the cross axle universal joint.
