Abstract

A toothed belt axis with a toothed belt, a toothed belt disk, a deflector, a profile body extending along a motion axis, a slide and a clamping apparatus. The slide includes a first front surface, into which first front surface a first reception opening extending along the motion axis for receiving the clamping apparatus is inserted. The profile body is configured for linearly movable guidance of the slide, the toothed belt can be driven by means of the toothed belt disk and can be deflected by means of the deflector, the slide being movable in the profile body by means of the toothed belt. The clamping apparatus includes a clamping body, a pressure plate, an annularly configured support body and a pressure member, the clamping body having a front side a back side, a reception room configured as a slot and a support portion.

First claim

The invention claimed is:

1. A toothed belt axis comprising a toothed belt, a toothed belt disk, a deflector, a profile body extending along a motion axis, a slide and a clamping apparatus, wherein the slide comprises a first front surface, into which first front surface a first reception opening extending along the motion axis for receiving the clamping apparatus is inserted, wherein the profile body is configured for linearly movable guidance of the slide, wherein the toothed belt can be driven by means of the toothed belt disk and can be deflected by means of the deflector, the slide being movable in the profile body by means of the toothed belt, the clamping apparatus comprising a clamping body, a pressure plate, an annularly configured support body and a pressure member, the clamping body having a front side a back side, a reception room configured as a slot and a support portion, wherein the reception room extends from the front side along the motion axis and passes through the clamping body transversely to the motion axis, wherein the reception room comprises a first inner surface and a second inner surface opposite the first inner surface, wherein the pressure plate comprises a pressure plate upper side with toothing and a pressure plate lower side, wherein the toothed belt comprises a toothed belt inner side with toothing, a toothed belt outer side and at least one end portion, wherein the pressure plate and the end portion are received in the reception room in such a way that the toothed belt outer side faces the second inner surface, the pressure plate lower side faces the first inner surface and the toothed belt inner side faces the pressure plate upper side, wherein the toothing of the pressure plate upper side is configured complementary to the toothing of the toothed belt inner side, wherein the pressure plate is pressed against the toothed belt by the pressure member resting on the pressure plate lower side in order to press the toothed belt outer side against the second inner surface, wherein the support body surrounds the support portion in order to prevent the reception room from widening.

2. The toothed belt axis according to claim 1 , wherein the clamping body comprises an outer circumferential surface, from which outer circumferential surface a first stop projects outwards in the radial direction and is positioned between the front side and the support portion.

3. The toothed belt axis according to claim 1 , wherein a second stop projects from the first inner surface in the direction of the second inner surface.

4. The toothed belt axis according claim 1 , wherein the toothed belt axis further comprises a tensioning screw, wherein the clamping body further comprises a through bore extending from the front side to the back side for receiving the tensioning screw and the slide further comprises a tensioning thread which extends from the first reception opening along the motion axis, wherein the tensioning screw can be screwed into the tensioning thread in order to adjust the tension of the toothed belt.

5. The toothed belt axis according to claim 1 , wherein the first reception opening comprises a guiding contour and the clamping body comprises a guiding area which is complementary to the guiding contour.

6. The toothed belt axis according to claim 1 , wherein the clamping body is made of a light metal.

7. The toothed belt axis according to claim 1 , wherein the support portion comprises a larger outer diameter than the remaining outer circumferential surface.

8. The toothed belt axis according to claim 1 , wherein the outer diameter of the support portion and the inner diameter of the support body have the same size.

9. The toothed belt axis according to claim 1 , wherein the clamping body is configured to be rotationally symmetrical at least in certain sections.

10. The toothed belt axis according to claim 1 , wherein the toothed belt axis further comprises a further clamping apparatus, wherein the slide further comprises a further front surface into which further front surface a second reception opening positioned opposite the first reception opening is inserted for receiving the further clamping apparatus, wherein the toothed belt comprises a further end portion which further end portion is received in the reception room of the further clamping apparatus.

11. The toothed belt axis according to claim 3 , wherein the second stop is positioned adjacent to the front side.

12. The toothed belt axis according to claim 6 , wherein the clamping body is made of aluminum.
