ABSTRACT:
The invention relates to an electromechanical linear drive, in particular for an injection moulding machine, comprising an electric motor with a hollow-shaft rotor, open on one side, with a subsequent screw gear which converts the rotational movement of the hollow-shaft rotor into a linear movement. The hollow-shaft rotor is supported on the motor housing, at the end thereof closed by a end wall, such as to rotate, by means of a central bearing spigot projecting axially from the end wall. According to the invention, an extremely stable-running, exactly central and fail-safe rotor bearing may be achieved with a simple construction and in an economical manner, whereby the bearing spigot is supported on the motor housing such as to rotate by means of at least two axially pre-tensioned, counter-rotating, individual bearings, separated in the longitudinal direction and supporting longitudinal and transverse forces and, in the region of the open rotor end, an emergency running safety device for an eccentric rotor displacement is provided.
