Abstract:
An electromechanical linear drive having a housing and a piston rod that passes through a housing end cover, and is carried by a spindle nut arranged longitudinally displaceably in a housing interior space. The spindle nut engages the motor-driven threaded spindle such that it is displaceable back and forth in the housing interior space by rotary motion of the spindle. A lubrication nipple is accessible on an outer side of the housing, and at least one lubrication passage extends from the nipple and opens to a stop surface located in the housing interior space, which stop surface forms an end stop for motion of the spindle nut. At least one lubrication conduit leads to lubrication sites of the spindle nut and is arranged in the spindle nut so that when the spindle nut is in abutment against the stop surface, the lubrication conduit is joined to the housing-side lubrication passage.
