    摘要: An electric actuator (13) comprises a housing (17) which contains a screw mechanism (11) and an electric motor (5) which is driveably connected to the screw mechanism (11) which provides a linear movement in response to a rotational movement of the electric motor (5), said screw mechanism (11) comprising a screw (12) and a nut (33) one of which is supported rotatably with respect to the housing (7) by means of an angular contact ball bearing (31), said screw (12) by means of an intermediate coupling element (18) engaging an actuating member (16) for transferring axial forces. The intermediate coupling element (18) engages the screw (12) by means of an axial connection (53, 54) which allows radial movements.

    摘要: A continuously variable transmission unit comprises two pulley sets (1, 2) which each comprises a pair of discs (66, 67) and a screw mechanism (12, 13) which is concentrated with respect to a pulley set (1, 2) for moving the discs (66, 67) of the pulley set (1, 2) towards and from each other, each pair of discs (66, 67) enclosing a V-shaped groove, a belt (5) stretching between the pulleys and accommodated in the grooves thereof, the screw mechanism (12, 13) being controllable by a control device, the discs (66, 67) of each pulley set (1, 2) being accommodated on a support shaft (68). The screw mechanism (12, 13) is accommodated in the bore in the shaft (68) and engaging at least on of the discs (66, 67).
