Abstract

A lubricated friction speed change gearing of the type which employs a plurality of cylindrical rollers mounted between a fixed outer race and a rotatable inner race in a compressed and elastically deformed condition, and a spider member having spider arms which are inserted between adjacent pairs of the rollers, thereby transmitting rotary power between the inner race and the spider member with change of rotational speed, wherein the spider members have substantially plane rigid surfaces which contact the outer surfaces of the rollers.
