Planet gear positioning and retaining mechanism

Abstract From the Canadian patent

Abstract of the Disclosure, Planet gears of a planetary gearing system for a vehicle drive wheel are mounted on a carrier for orbital motion around a motor-driven sun gear and transmit drive at reduced speed to a ring gear which turns the wheel hub. Each planet gear is fastened to the carrier through a bearing and axle pin having ends which extend through support bores in the carrier. Lubricant is maintained around the carrier and each axle pin has a lubricant passage with an outlet directed toward the bearing and with an inlet facing in the direction of orbital motion of the axle pin to cause such motion to force lubricant into the passage. Longitudinal movement of all axle pins and also …
