Abstract

A press includes two components and a clamping element insertable in an axial direction, via an actuating element which is axially displaceable via an actuator, radially between a region of the first component and a region of the second component. The actuating element passes through the components and the clamping element in the axial direction. The actuating element at one end cooperates with the actuator and at the other end includes a cover element via which the actuating element is actively connected to the components. The clamping element is arranged between the cover element and the components, or between the components and a housing region of the actuator. The actuating element and/or the actuator is movable by the actuator, for insertion of the clamping element between the components, in a scope reducing an axial distance between the cover element and the housing region of the actuator.

First claim

The invention claimed is:

1. An arrangement with a press, comprising:
an actuator including a housing region;
an actuating element having a first end and an opposite second end and being displaceable in an axial direction by the actuator;
a first component and a second component;
a clamping element positioned radially between a region of the first component and a region of the second component and which is movable in the axial direction by the actuating element;
a cover element;
the actuating element passing through the first component, the second component and the clamping element in the axial direction, the first end of the actuating element operatively connected with the actuator and the second end connected to the cover element to connect the actuating element to the first and second components;
the clamping element being axially arranged between 1) the cover element and the first and second components, and/or 2) the housing region of the actuator and the first aid second components;
wherein displacement in the axial direction of the actuating element and/or the actuator moves the clamping element between the first and second components to reduce an axial distance between the cover element and the housing region of the actuator.

2. The arrangement according to claim 1 , wherein the actuator is a hydraulic actuator and the actuating element is actuated hydraulically via the actuator.

3. The arrangement according to claim 1 , and further comprising housing-side stops positioned in a region of the actuator that limit an actuation travel of the actuating element and/or the actuator.

4. The arrangement according to claim 1 , wherein the clamping element is a clamping sleeve which is cylindrical in an outer peripheral region and conical at an inner periphery, wherein an inner diameter of the inner periphery diminishes in a direction away from an axial interior of the first and second components toward an axial exterior of the first and second components.

5. The arrangement according to claim 4 , wherein a radially inner one of the first and second components includes, in an area of the clamping sleeve, a conical outer contour corresponding to the conical inner periphery of the clamping sleeve, while a radially outer one of the first and second components includes a cylindrical outer contour in an area of the clamping sleeve.

6. The arrangement according to claim 3 , wherein a distance between the housing-side stops corresponds at least to an axial length of a region of the clamping element by which the clamping element is insertable between the first and second components by the the actuating element and/or the actuator.

7. The arrangement according to claim 1 , and further comprising a first joint region between the clamping element and a radially inner one of the first and second components, wherein the radially inner one of the first and second components includes a conduit via which hydraulic fluid is conducted under pressure into the first joint region.

8. The arrangement according to claim 1 , and further comprising a first joint region between the clamping element and a radially inner one of the first and second components and a second joint region between the clamping element and a radially outer one of the first and second components, wherein the clamping element includes a conduit via which hydraulic fluid is guided between the first joint region and the second joint.

9. The arrangement according to claim 1 , and further comprising a further clamping element, with the clamping element and the further clamping element being displaceable in the axial direction between the first and second components by displacement of the actuating element and/or the actuator, starting from sides of the first and second components facing away from each other, to displace the clamping element and the further clamping element in a direction toward an axial interior of the first and second components.

10. The arrangement according to claim 1 , and further comprising a spacer element arranged in the axial direction between the cover element or the housing region of the actuator and at least one of the first and second components.

11. The arrangement according to claim 1 , wherein a radially inner one of the first and second components is a bearing bolt of a planet wheel and a radially outer one of the first and second components is a planet carrier of a planetary gear mechanism.
