Abstract
A transmission wheel for a platform transmission apparatus includes a wheel frame having a disk with a central hole for fixing to a drive axle, and a plurality of ball rollers carried on each side of the disk by supports which extend axially. The ball rollers on each side of the disk each have a circular arc camber which lies on a common circle concentric to the axis, the rollers on each side being evenly spaced apart and staggered from the rollers on the other side. The supports include concave portions which correspond to the circular arc camber and also enhance the rigidity of the wheel frame.
