| 摘要 | PURPOSE: To drive a valve both in a manual way and in a motor-operated way without a clutch mechanism by installing a planetary gear on a drive sleeve of a valve shaft, manually rotating an internal gear to be engaged with the planetary gear, and rotating a sun gear to be engaged with the planetary gear by a motor. CONSTITUTION: A planetary gear group 40 is installed on a drive sleeve 60 to move a valve shaft 59 vertically. An internal gear 80 to be engaged with the planetary gear group 40 is connected to a manual ring 16 through a worm gear mechanism 28. A sun gear 50 to be engaged with the planetary gear group 40 is connected to a motor 14 through a worm gear mechanism 25. As the manual ring 16 is rotated, the internal gear 80 is rotated, but as the sun gear 50 is stopped, the planetary gear group 40 rotates the drive sleeve 60. As the motor 14 is rotated, the sun gear 50 is rotated, but as the internal gear 80 is stopped, the planetary gear group 40 rotates the drive sleeve 60. COPYRIGHT: (C)1990,JPO |
