A gearbox assembly includes a gearbox housing containing a worm shaft and a worm wheel, the worm shaft incorporating one or more external helical worm teeth; a main bearing assembly supporting the worm shaft at an end closest to the motor; a tail bearing assembly supporting the worm shaft at an end farthest from the motor, at least the tail bearing assembly being free to move relative to the housing within a limited range of motion by enabling the worm shaft to move radially away from the axis of the worm wheel, and the gearbox assembly further comprising a flexible coupling, the worm shaft is connected to a power output piece from the motor at the end part of the main bearing, so that torque is transmitted from the motor to the worm shaft; the flexible coupler includes a first hub portion providing connection with the worm shaft, a second hub portion providing connection with a power take-off from the motor, and a flexible membrane connecting the first hub portion to the second hub portion, the flexible membrane providing a main path for transmitting torque from the first hub portion to the second hub portion.
一种齿轮箱组件,包括:齿轮箱壳体,容纳蜗杆轴和蜗轮,该蜗杆轴结合一个或多个外部螺旋蜗杆齿;主轴承组件,在最靠近马达的端部处支撑蜗杆轴;尾轴承组件,在最远离马达的端部处支撑蜗杆轴,至少尾轴承组件能够相对于壳体在有限运动范围内自由移动通过使得蜗杆轴能够背离蜗轮的轴线径向移动,并且该齿轮箱组件进一步包括柔性联接器,在主轴承端部处将蜗杆轴连接至来自马达的动力输出件,以将转矩从马达传递至蜗杆轴,其特征在于,柔性联接器包括提供与蜗杆轴的连接的第一毂部分、提供与来自马达的动力输出件的连接的第二毂部分、以及将第一毂部分连接至第二毂部分的柔性膜,该柔性膜提供了用于将转矩从第一毂部分传递至第二毂部分的主路径。
