Abstract
The crossed axle traction drive developed by authors has been applied to the new mechanism of CVT. The input and output shafts attaching conical disks are parallel and a idler shaft having conical roller at the end is placed across the input/output shafts. The relation between the movements of each axis to change a ratio is analyzed geometrically. This report deals with the development of prototype and evaluation of efficiency of the transmission. From the result of experiments, the efficiency is 77% in case of the constant loading force.
