REDUCER WITH DOUBLE-CLUTCH STRUCTURE

摘要

A reducer with a double-clutch structure includes a source power input shaft and a power output shaft. A speed reduction mechanism includes a driving device and a driven device installed on the output shaft. A first clutch device is arranged on the output shaft and is driven by the driven device thereby driving the output shaft. A second clutch device is arranged on the output shaft and is meshed with the driven device to drive the output shaft. A clutch control device operates the first clutch device and the second clutch device simultaneously to move between the engaging position and the disengaging position. The first clutch device engages earlier than the second clutch device and disengages later than the second clutch device. When the clutch control device operates the second clutch device to move axially to an engaging position from a disengaging position, the first clutch device is axially pushed to the engaging position from the disengaging position by the second clutch device.

主权项

1. A reducer with a double-clutch structure, comprising:
a source power input shaft and a power output shaft; a shell for accommodating components, a speed reduction mechanism being arranged inside the shell and including a driving device and a driven device mated with the driving device; the driven device being installed on the output shaft and freely rotating around the output shaft; a first clutch device arranged on the output shaft synchronously and rotatably, the first clutch device being movable along the output shaft between an engaging position and a disengaging position; the first clutch device being driven by the driven device in the engaging position and driving the output shaft when driven by the driven device; a second clutch device arranged on the output shaft synchronously and rotatably, the second clutch device being movable along the output shaft between the engaging position and the disengaging position; the second clutch device being meshed with the driven device in the engaging position and driving the output shaft; a clutch control device which operates the first clutch device and the second clutch device simultaneously to move in the first and second clutch control devices between the engaging position and the disengaging position; the first clutch device configured to engage earlier than the second clutch device and to disengage later than the second clutch device, wherein, the first clutch device is axially arranged between the driven device and the second clutch device; the first clutch device and the second clutch device rotate coaxially and synchronously; and when the clutch control device operates the second clutch device to move axially to the engaging position from the disengaging position, the first clutch device is axially pushed to the engaging position from the disengaging position by the second clutch device.
