A REVIEW ON DESIGN, DEVELOPMENT, TESTING AND OPTIMIZATION OF THOMPSON CV JOINT WITH BRASS AND PHOSPHOR BRONZE AS TRUNNION MATERIAL

In direct mechanical drive system, coupling of various driven elements is required. Majority of drive elements like gear reducers, lead screws and host of other components are driven by shaft that is supported by multiple bearings. Due to rigidity of coupling, slight misalignments will be there between a driving and driven shaft. The function of power transmission coupling is transmitting torque from driving shaft to drive shaft along with shaft misalignment. Misalignment in shaft may results into unwanted strains on shaft bearings causing to wear out. Few conventional solutions are available for misalignment problems like Oldham’s coupling and universal joint which have several limitations. These limitations can be overcome with Thompson constant velocity (CV) coupling which offers features like minimizing side loads, higher misalignment capabilities, more operating speeds, improved efficiency of transmission and many more. This paper presents review on constant velocity joints/couplings design and optimization. In this paper the research work of various researchers related to transmission couplings and constant velocity joints is reviewed.
