Abstract
A reduction gear of the present invention is compact and light and can be used for tire portions of an apparatus for travelling, etc. Each of outer and inner pins is formed by a rolling bearing. The reduction gear includes block-shaped lubricating members which supply a lubricant to the outer rings of the outer pins to thereby lubricate them, and a ring-shaped lubricating member which supplies the lubricant to the outer rings of the inner pins to thereby lubricate them. The lubricant can be supplied to a pair of cycloid gears through the outer pins and the inner pins for lubrication. Since the cycloid gears, the outer pins, and the inner pins are lubricated by the lubricating members, the reduction gear can enhance its durability, reduce the friction between components to thereby lower the frictional resistance, and realize a light and compact structure.
