Patent ID: 8402853

Claim:
A linear motion device, comprising: a first assembly; a second assembly which is linearly movable relative to the first assembly; at least one first rolling surface provided on the first assembly, said at least one first rolling surface extending in a longitudinal direction, wherein the first rolling surface is disposed opposite a second rolling surface that is provided on the second assembly; an endlessly circulating row of rolling elements located between the first and second rolling surfaces, the first assembly including a rotatable threaded spindle that extends parallel to the longitudinal direction and is engaged with a threaded nut, the threaded nut being a component of the second assembly, wherein the first assembly includes an electric motor that is connected to the threaded spindle in a rotationally driving manner, and wherein a rotational axis of said electric motor extends parallel to the threaded spindle, the first assembly including a single-pieced, first body, wherein the threaded spindle and the electric motor are located next to one another in a direction transversely to the longitudinal direction, wherein the threaded spindle is disposed substantially entirely inside the first body, wherein the electric motor is disposed fully inside the first body, wherein the electric motor and the first rolling surface do not overlap in longitudinal direction, and the first assembly has return channels for the endlessly circulating row of rolling elements.
