摘要： Provided is an injection molding machine using a built-in type motor as a measuring electric servomotor. In order to reduce the entire length of the machine (the injection molding machine), the metering electric motor is exemplified by a hollow built-in type motor, which includes a cylindrical stator, and a cylindrical rotor positioned in the stator. A sleeve is fixed in the rotor of the built-in type motor, and a member fixing the rear end portion of a screw and the sleeve are connected/fixed. Moreover, a nut member as a straight portion of a ball screw mechanism for converting the rotation of an injecting electric motor into linear motions and the sleeve are connected/fixed.

摘要： The invention relates to an electromechanical linear drive, in particular for an injection moulding machine, comprising an electric motor (1) with a hollow-shaft rotor (5), open on one side, with a subsequent screw gear (6) which converts the rotational movement of the hollow-shaft rotor into a linear movement. The hollow-shaft rotor is supported on the motor housing (2), at the end thereof closed by a end wall, such as to rotate, by means of a central bearing spigot (10) 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 (11, 12), 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 (14, 15) for an eccentric rotor displacement is provided.

摘要： An injection apparatus includes an injection part (2) configured to pressurize and thereby inject melted resin. A motion conversion mechanism is configured to convert rotational motion generated by an injection drive unit (50) into linear motion of the injection part (2). A load transmission mechanism is configured to transmit a load, applied to the injection part as a reaction force of the melted resin, to a strain unit (74) via at least a part of the motion conversion mechanism. The load transmission mechanism includes a thrust bearing (71) configured to receive the load, and an inner circumferential portion of the strain unit (74) is attached to a bearing holder (73) that holds an outer circumferential portion of the thrust bearing (71).
