Reduction gear and an electric actuator including such a reduction gear
Abstract:
This reduction gear of an electric actuator (1) for driving a home screen, the reduction gear comprises a reduction stage having a sun gear (42) meshing with at least one planet gear (46, 46′) rotating about a respective shaft (47) and positioned in a drum (45), the planet gear meshing with a stationary ring (48) to drive the drum (45) in rotation about an axis of rotation (X4). The reduction gear further comprises first guide means (43) serving both to guide the sun gear (42) in rotation and to guide the drum (45) in rotation about the axis of rotation (X4).
Abstract(Chinese):

用于驱动主屏幕的电致动器（1）的该减速齿轮，所述减速齿轮包括具有与围绕相应轴（47）旋转的至少一个行星齿轮（46,46'）啮合的太阳齿轮（42）的减速台 ）并定位在滚筒（45）中，所述行星齿轮与固定环（48）啮合，以围绕旋转轴线（X4）旋转以驱动滚筒（45）。 所述减速装置还包括第一引导装置（43），用于同时引导太阳齿轮（42）旋转并引导滚筒（45）围绕旋转轴线（X4）转动。
