Rotary power coupling and planetary gear winch

摘要

Disclosed herein is a rotary power coupling comprising rotatable spaced-apart driving and driven members and a torque-transmitting coupling plate interposed therebetween. The coupling of the invention is of particular use in those applications wherein it is of value to isolate power train components and/or assemblies from certain operational strains imposed upon the power user. In a planetary gear winch assembly the coupling of the invention is located in the power train between the output of the final planetary gear speed reduction stage and the winch drum.
