Abstract
A power transmission device includes: a planetary gear mechanism; and a case accommodating the planetary gear mechanism, in which the planetary gear mechanism includes an input shaft, a sun gear, a plurality of planetary gears, a planetary carrier, and a ring gear, the sun gear is an external gear provided on the input shaft, a gear member is attached to one end of the input shaft, a baffle plate extending between the gear member and the sun gear is attached to the case, and at least a part of the gear member and the planetary gear mechanism is immersed in a lubricating liquid stored in a lower portion of the case.
Claims5
A power transmission device comprising:
- a planetary gear mechanism;
- and
- a case accommodating the planetary gear mechanism, wherein
- the planetary gear mechanism includes an input shaft, a sun gear, a plurality of planetary gears, a planetary carrier, and a ring gear,
- the sun gear is an external gear provided on the input shaft,
- a gear member is attached to one end of the input shaft,
- a baffle plate extending between the gear member and the sun gear is attached to the case,
- at least a part of the gear member and the planetary gear mechanism is immersed in a lubricating liquid stored in a lower portion of the case, and
- the gear member is a driven sprocket around which a chain is wound.
