Design and Development of Planetary Final Drives for Agricultural Tractors 730862

Durability of planetary final drive gearsets for use in large agricultural tractors can be enhanced by modifying gear tooth profiles, adding sufficient rigidity to the system, and floating at least one of the members. Properly applied to the design, these procedures may also reduce the need for close manufacturing tolerances Their application was instrumental in providing a successful planetary final drive design for the Allis-Chalmers Models 7030 and 7050 agricultural tractors.
