Embodiment Construction

[0071] exist figure 1 A drive device (1') for generating a translational movement of a movable tappet (8) by means of an electromagnetic rotary machine is schematically shown in .

[0072] The drive (1') can comprise, for example, the following components: housing flange (1) with stator tube or stator sleeve (2), protective cover (3), rotor (4), provided with winding (12) The stator (5) or the stator plate group (5), the screw (6) together with the nut (7) and the tappet (8) and the joint (9) for the control and power electronics, the winding and the sensor system (13) Being connected.

[0073] The stator (5) is arranged coaxially with respect to the rotor (4) and comprises at least one pair of moving threads (6, 7) coaxially integrated therein, said pair of moving threads comprising a non-rotatably coupled rotor (4) connected screw (6) and a nut (7) guided linearly in a torsionally fixed manner in the stator sleeve (2), which is preferably rigidly coupled to a tubular tapp...

Abstract

The invention relates to a drive device (V) for producing a translational motion of a movable tappet (8) by means of an electromagnetic rotating machine, comprising at least one rotor (4) and one stator (5), which is arranged coaxial to the rotor (4), having at least one movement-thread pair integrated coaxially in the stator, said movement-thread pair comprising a lead screw (6), which is coupledto the rotor (4) for conjoint rotation, and a threaded nut (7), which is linearly guided in a stator sleeve (2) in a rotationally fixed manner and is rigidly coupled to the tappet (8), the rotor (4)being guided for rotation around the stator (5), a torque being transferred from the rotor (4) to the lead screw (8) by means of a thin-walled flange (10), a rotational fixation (11) of the threaded nut (7) in the cavity of the stator sleeve (2) being provided as a result of interlocking joining of the two.

Description

technical field [0001] The invention relates to a drive device for converting the rotational movement of a rotor of an electromagnetic rotary machine into a translational movement of a movable tappet. Background technique [0002] Stepper BLDC and DC motors are known from DE 10 2013 005 732 A1 and US 9 548 637 B2, which have a friction-fit connection of the rotor to the main shaft via a conical press fit, wherein the corresponding connecting elements are characterized by their inner cone and outer The cone requires a lot of space in the axial direction and therefore the overall length of the arrangement for a given displacement stroke increases. [0003] Furthermore, the arrangements proposed in DE 10 2013 005 732 A1 and US 9 548 637 B2 are provided with spacer (5) (English spacer (5)), which likewise increases the overall length of the arrangement, not here Contributes to movement stroke or driving force. [0004] A linear servo drive is known from DE 10 2015 219 502 A1, ...
