Abstract: The present invention relates to a linear actuator (1) comprising an outer tube (3) secured to a console and a rear mounting (5) and a front mounting (7) for mounting the linear actuator (1). The linear actuator (1) further comprises a motor housing (6) which constitutes a first part of an actuator housing (2) The linear actuator (1) further comprises an inner tube (4) which at its outermost end is secured to the front mounting (7) and with its other end is in connection with a spindle nut on a spindle. Through a transmission an electric motor causes the spindle to rotate at which the spindle nut and the inner tube will be moved in an outwards or inwards direction depending on the direction of rotation of the spindle. The spindle nut and the inner tube are guided telescopically in the outer tube. The spindle nut and the inner tube are secured against rotation in the outer tube.

Abstract: Linear actuator comprising a housing (1), a reversible electric motor (7), a transmission (22), a spindle (5) driven by the electric motor through the transmission (22), a bearing (31) for embedding the spindle (5), a spindle nut (6) secured against rotation on the spindle, an outer tube (3) surrounding the spindle, an activation element (4) telescopically embedded in the outer tube (3) and connected to the spindle nut (6), a rear mounting (9) designed as a separate element and secured in the housing for mounting of the actuator. The rear mounting (9) is equipped with a seat (35) for the bearing (31) of the spindle. The seat (35) is connected to an opening (36), which is guided out on the side of the rear mounting (9), so that the bearing (31) of the spindle may be inserted sideways in the seat (35). Thus a linear actuator is provided having a rear mounting which is easier to mount and ensures an easier handling during the assembly of the linear actuator.

Abstract: Linear actuator comprising a housing (1) consisting of at least two parts (1 a, 1 b) a mounting console (2) a reversible motor (7) with a transmission (22), a spindle (5) which over the transmission is driven by the motor, a bearing (16) for embedding the spindle (5), a spindle nut (6) secured against rotation on the spindle, an outer tube (3) which surrounds the spindle, an activation element (4) telescopically mounted in the outer tube (3) and connected to the spindle nut (6), a front mounting (8) on the outer end of the activation element (4), a rear mounting (9) arranged in the housing. In the rear mounting (9) is a seat for the bearing (31) of the spindle. The motor (7), the transmission (22) and the outer tube (3) is secured to the console (2). The mounting console (2) is constructed as a separate element around which the two parts (1a, 1 b) of the housing is assembled and the mounting console (2) constitutes alone the bearing chassis of the actuator.
