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) surroun
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.

1. A linear actuator comprising: a housing,a reversible electric motor,a transmission,a spindle driven by the electric motor through the transmission,a bearing at a shaft end of the spindle,a spindle nut secured against rotation on the spindle,an outer tube surrounding the spindle,an activation element connected to the spindle nut, anda rear mounting designed as a separate element and secured in the housing for mounting of the actuator, the rear mounting including a recess forming a seat, a first opening which extends to an end of the rear mounting through which the shaft end of the spindle can extend with the bearing, and a second opening which extends laterally of the first opening and outwardly to a side of the rear mounting so that the bearing can be inserted sideways into the rear mounting and against the seat, wherein said seat, said first opening and said second opening provide a U-shaped channel, and including a closing element closing the U-shaped channel, and wherein the closing element fits into the U-shaped channel and slides along the U-shaped channel to contact a spindle bearing located therein. 2. The linear actuator according to claim 1, wherein the dosing element comprises a tongue at each side, which fits into a spline in the side of the second opening. 3. The linear actuator according to claim 1, including a circular opening in the housing into which the rear mounting protrudes and inside the housing, on a rim along the opening, is a row of teeth, and on the rear mounting, at least over a section, is a corresponding row of teeth which cooperates with the teeth in the housing, such that the rear mounting is secured against unintended rotation about its axial axis. 4. The linear actuator according to claim 3, wherein the rear mounting comprises two sections with teeth located opposite each other. 5. The linear actuator according to claim 4, wherein one of the sections with teeth is constructed on the closing element. 6. The linear actuator according to claim 1, wherein the closing element is arc-shaped.
