Circular thrust gear has working circles for ring gear and spur gearwheel with equal curve length of tooth and tooth gap pitch, so amount of eccentricity of driving eccentric is defined for circular thrust speed equal to driven speed

摘要

The circular thrust gear comprises a ring gear, spur gearwheel, and drive eccentric. The working circles for the ring gear and spur gearwheel with the unequal tooth and tooth gap quantities necessary for a gear reduction have an equal curve length of the tooth and tooth gap pitch, therefore the amount of eccentricity of the driving eccentric is defined for a circular thrust speed equal to the driven speed with regard to the mid-tooth height of the driven ring gear.
