Abstract

A joint system is provided that includes a dashed threaded fastener and a first fastener with a threaded aperture. The first fastener has at least one planetary gear with a second fastener on a surface thereof directed toward the dashed threaded fastener and a circumferential support rail. The planetary gear is disposed between the dashed threaded fastener and the circumferential support rail such that the planetary gear is rotatable round its axis. The dashed threaded fastener is configured to conduct a rotational movement such that the dashed threaded fastener moves along its axis through the first fastener. The planetary gear and the circumferential support rail rotate simultaneously in an opposite direction to the rotational movement of the dashed threaded fastener.

Claims (16)

1. A joint system for fastening or assembling components via a bolted joint, comprising:

a dashed threaded fastener having a dashed thread;

a first fastener with a threaded aperture into which the dashed threaded fastener is threaded, wherein the first fastener includes at least one planetary gear with a second fastener on a surface of the first fastener directed toward the dashed threaded fastener, the second fastener being screwed to at least one of the components, and the at least one planetary gear being meshed with the dashed thread; and

a circumferential support rail,

wherein the at least one planetary gear is disposed between the dashed threaded fastener and the circumferential support rail such that the at least one planetary gear is rotatable round an axis thereof,

wherein the dashed threaded fastener is configured to conduct a rotational movement to move the dashed threaded fastener along the axis through the first fastener, and

wherein the at least one planetary gear and the circumferential support rail are configured to rotate simultaneously in an opposite direction to the rotational movement of the dashed threaded fastener.

2. The joint system according to claim 1 , wherein a gear ratio between the dashed threaded fastener and the at least one planetary gear is such that the rotation in the opposite direction of the second fastener is greater than the rotational movement of the dashed threaded fastener.

3. The joint system according to claim 1 , wherein the first fastener includes at least two mirror-symmetrically arranged planetary gears wherein each of the planetary gears includes the second fastener.

4. The joint system according to claim 1 , wherein the second fastener includes a tip having an acute angle.

5. The joint system according to claim 1 , wherein the second fastener is formed as a helical shape.

6. The joint system according to claim 1 , wherein the first fastener includes an inner support rail having a projection and the projection fits in a groove of the threaded fastener.

7. The joint system according to claim 1 , wherein the first fastener includes a connecting element on which the at least one planetary gear with the second fastener is mounted and rotatable.

8. The joint system according to claim 1 , wherein the at least one planetary gear is formed of a different material than the dashed threaded fastener and the first fastener.

9. The joint system according to claim 1 , wherein the circumferential support rail is mounted on the surface of the first fastener.

10. The joint system according to claim 1 , wherein the circumferential support rail is formed integrally with a further support tool.
