Abstract

The toroidal traction-drive CVT transmits power by the shearing action of lubricant film under heavy loads at the contact ellipse on the rollers. Furthermore, due to the geometry of the toroidal CVT, spin motion is produced in the contact ellipse. These contact ellipses are where shear stress of the lubricant generates frictional heat. In this report, temperature rise in the traction contact areas of toroidal CVTs were analyzed using a traction analysis program after measuring temperature rise with a twin-disc test machine and comparing experimental results with calculated results. The influences of half-cone angles on temperature rise were discussed.
