Abstract
A winch design for consumer applications wherein the planetary carrier assemblies are split between the two ends of the drum. The drum is mounted on heavy duty brackets and the housing elements surround the planetary carrier assemblies and also, independent of the drum, are mounted to the brackets. The housing elements are molded with the ring gear configured therein. They are produced from the same moldings. Interconnection as between the planetary carrier assemblies is through an interconnect shaft that is driven by the output shaft of the first planetary carrier assembly (coupled to the motor drive shaft) and carries the sun gear of the second planetary carrier assembly.
