Abstract
A traction surface cooling method and apparatus for traction drive transmissions capable of continuous speed ratio variation in which a traction lubricant is circulated over a defined sector of a traction surface spaced from the point of rolling frictional contact of that surface with a cooperating traction surface. Provision is made for wiping the traction surface at the leading end of the sector to cleanse the surface of lubricant for more effective heat transfer from the surface to freshly circulated lubricant, and at the trailing end of the sector for preventing an excessively thick film of lubricant on the surface proceeding to the contact point.
