Title:
ROTATIONAL PHASE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3837725
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable adjustment of rotation phase difference between input torque and output torque at an optional angle.
SOLUTION: This device comprises a planetary gear mechanisms 20a, 20b, a sun gear mechanism 30 and a ring gear mechanism 10. Input torque is input to planetary gear mechanisms 20a, 20b. Control torque is input to the sun gear mechanism 30. The ring gear mechanism 10 transmits output torque to a cam shaft. In the planetary gear mechanisms 20a, 20b, planetary gears each enabled autorotation are rotated around a first rotary shaft. Torque is input to the first rotary shaft. The ring gear mechanism 10 has a second rotary shaft coaxial with the first rotary shaft, and meshed with the planetary gears from the outside. The sun gear 30 is meshed with the planetary gear from the inside, and has a third rotary shaft coaxial with the first and second rotary shafts. Angular phase difference between the first and second rotary shafts is controlled by applying load torque to the third rotary shaft of the sun gear 30.
