Definitions
- At least one other of the connecting sections is coupled to the other of the units or can be coupled to an element to be driven.
- one unit can be clearly positioned relative to the other unit or the drive movement can be transferred to an element to be driven.
- the connecting sections are arranged in tabs integrally connected to the planar stiffening body and solid joints are formed by recesses in the tabs.
- the coupling element can be produced from a coherent material in a simple manner. It can be advantageous if the coupling element is a one-piece flat sheet or is composed of several flat sheets. This enables the coupling element to be produced inexpensively and easily, for example by stamping.
- 3a and 3b show different views of a drive according to the invention according to a second embodiment.
- the connecting sections 4a2 are connected to the planar stiffening body 4a1 via solid joints 4a3.
- the solid joints 4a3 are formed by spa stanchions 4a5 in the tabs 4a4 and through incisions along the outer contour of the coupling element 4a (incisions between the legs).
- the connecting sections 4a2 are connected in an articulated manner to the planar stiffening body 4a1.
- Fig. 1 As can be seen in Fig.
- the rotor 3 is driven via two diametrically opposed guide elements 5 which protrude through openings in the stator 2 and move relative thereto.
- the guide elements 5, in particular their longitudinal axes it is necessary for the guide elements 5, in particular their longitudinal axes, to always be at the same distance from one another and to be aligned exactly congruently with the longitudinal axes of the openings in the stator 2.
- the coupling element 4b which is connected both to the stator 2 and to the rotor 3
- forces that act perpendicular to the direction of movement x on the rotor 3 can be diverted directly into the stator 2, so that the position and location of the rotor 3 and the guide elements 5 is not influenced by these forces.
- the coupling element 4b can also consist of a one-piece metal sheet or of several metal sheets assembled together.
