Electromechanical actuator and shading device comprising such an electromechanical actuator

Abstract

An electromechanical actuator and shading device comprising such an electromechanical actuator. An actuator (11) includes a reduction gear (19), which includes a first stage (37) and a second stage (39), and a centering shaft (71). The first stage (37) includes a bearing (76), which includes a first bore (77) and a second bore (78). The bearing (76) is mounted inside a bore (74) of a planet carrier (66) of the first stage (37) with an interference fit. The centering shaft (71) is mounted inside the first bore (77) of the bearing (76) with a loose fit. In addition, a shaft (59) of a sun pinion (40) of the first stage (37) is mounted inside the second bore (78) of the first bearing (76) with a loose fit. Figure for the abbreviation: Figure 6.
