The invention relates to a rotary drive reduction gear or reduction gear motor in an electric brake actuator. The invention relates to a planetary gear train comprising one or more planetary gear sets (2) parallel or coaxial to a linear actuation direction (500), said planetary gear sets having at least one rotationally fixed ring gear (21). The reduction gear comprises a damping device (204) at least partially made of an elastomeric material, said damping device being arranged around the fixed ring gear and being radially and/or axially compressed between the fixed ring gear and the brake housing (41). Generally, the reduction gear is a differential planetary gear set (2) driven by a sun gear having planetary gears (22) that mesh with both a fixed ring gear (21) and a movable ring gear (23). The latter drives a nut of a reversible screw-nut mechanism (3) generating a linear force. The overall irreversibility is generated by the differential gear set. The invention also relates to a component for determining a damper for implementing said reduction gear, to a motor unit comprising said damper, to a brake and to a method for assembling said damper.

    本发明涉及一种电制动执行器内的旋转驱动减速齿轮或减速齿轮马达。其包括与线性致动方向(500)平行或同轴的一个或更多个行星齿轮组(2),所述行星齿轮组具有至少一个旋转固定齿圈(21)。该减速齿轮包括至少部分由弹性体材料制成的阻尼装置(204),所述阻尼装置围绕固定齿圈布置,并在固定齿圈和制动器壳体(41)之间被径向和/或轴向压缩。通常,所述减速齿轮是由具有行星齿轮(22)的太阳齿轮驱动的差动行星齿轮组(2),行星齿轮(22)与固定齿圈(21)和可动齿圈(23)同时啮合。后者驱动产生线性力的可逆螺杆‑螺母机构(3)的螺母。整体的不可逆性是由差动齿轮组产生的。本发明还涉及一种确定用于实现所述减速齿轮的阻尼器的部件、一种包括所述阻尼器的马达单元、一种制动器以及一种装配所述阻尼器的方法。
