Abstract
An electromechanical actuator comprises a casing, an electric motor, a gearbox, a spring-applied brake (25) and a centring shaft (71). The brake (25) comprises a coil spring (48), a drum (49), an input member (50), an output member (51) and a bushing (76). The input member (50) comprises a first bore (72). The output member (51) comprises a first bore (73) and a second bore (74). The shaft (71) is mounted inside the first bore (73) of the output member (51) and a bore of a sun gear of a reduction stage of the gearbox. The bushing (76) comprises a bore (77), inside which the shaft (71) is mounted. The bushing (76) is mounted inside the first bore (72) of the input member (50) with an interference fit and inside the second bore (74) of the output member (51) with a loose fit.
