Abstract:Based on Hertz theory of elastic contact and the design theory of ball bearings, a new type of rolling coupling was designed. The two halves of the rolling coupling can be moved relatively by a small axial force when a great moment is exerted on it. The rolling coupling was used to connect the principal axis and the decelerator of continuous extrusion machine and it can greatly decrease the harmful axial forces on the continuous machine. The engineering formulas for the contact stress and distance of apporach of the rolling elements were deduced and the method
for designing the rolling couplings was proposed. The formulas for the forces exerted on the rolling element were verified by the experiment.

 

Key words: rolling coupling; principal axis; axial force; Hertz theory; elastic distortion; contact stress; exact constraint
