Abstract: A spindle drive includes a housing, a spindle, e.g., a threaded spindle, a trapezoidal threaded spindle, a ball circulation spindle or planetary roller spindle, and a spindle nut that is operatively connected to the spindle. The spindle nut is guided on the housing in a manner that allows it to be moved back and forth in response to rotational movement of the spindle in the axial direction thereof. On at least one axial side, the spindle nut includes an annular groove or is connected, e.g., screw-connected, to a part that has an annular groove. An annular collar is formed on the housing. The collar enters or extends into the annular groove in response to the spindle nut reaching an associated or a corresponding axial position.

Abstract: A cooling system for a geared motor, and a geared motor having electric motors and a gear unit as well as an adapter which is disposed between the electric motors and the gear unit, the electric motors having ducts for a coolant, in particular, a coolant, especially a cooling liquid, being able to flow through each of the motors which, in particular, are liquid-cooled, the streams of coolant emerging from the ducts being brought together and being fed at least proportionally by a first distributor to the gear unit in order to lubricate and cool the toothing parts of the gear unit.
