The invention relates to a rotary drive reduction gear or geared motor within an electric brake actuator. It comprises one or more planetary gear sets (2) parallel or coaxial to the linear actuation direction (500), which are provided with at least one rotationally fixed ring gear (21). This reduction gear comprises a damping device (204) made at least partially of an elastomer material, which is arranged around the fixed ring gear and compressed radially and/or axially between the fixed ring gear and a brake housing (41). Typically, the reduction gear is a differential planetary gearset (2) driven by its sun gear with planet gears (22) meshing simultaneously with the fixed ring gear (21) and a movable ring gear (23). The latter drives the nut of a reversible screw-nut mechanism (3), which produces the linear force. The overall irreversibility is produced by the differential gearset. The invention also relates to a component determined for producing the damper of this reduction gear, to a motor unit including this damper, to a brake and to a method for assembling same.
