Abstract

A clamping sleeve mounts a rotation sensor in a receiving opening which is provided in a receiving device and which has a longitudinal axis parallel to an intended mounting direction. The clamping sleeve is designed to be inserted at least partially into the receiving opening in the direction of the longitudinal axis and to be held therein by frictional engagement. The clamping sleeve is further designed corresponding to the rotation sensor to be mounted, such that, upon insertion of the rotation sensor into the clamping sleeve, a form-fit engagement between the rotation sensor and the clamping sleeve can be established.

First claim

The invention claimed is:

1 . A clamping sleeve for mounting a rotation sensor in a receiving opening which is provided in a receiving device and which has a longitudinal axis, comprising: a lateral surface of the clamping sleeve that extends in a direction of the longitudinal axis, at least in some section or sections, wherein the clamping sleeve is configured to be inserted at least partially into the receiving opening and to be held therein by frictional engagement, and the clamping sleeve is configured so as to correspond to the rotation sensor to be mounted, such that, upon insertion of the rotation sensor into the clamping sleeve, positive engagement is established between the rotation sensor and the clamping sleeve; wherein the clamping sleeve has a slot in the direction of the longitudinal axis, at least in some section or sections, and said slot is open at least on a side facing the rotation sensor during assembly; wherein the slot has a radially inwardly inclined end section on both sides of the slot extending in the direction of the longitudinal axis, and the end sections are configured such that the positive engagement is established between the rotation sensor projection of the rotation sensor when the rotation sensor is inserted into the clamping sleeve.

2 . The clamping sleeve as claimed in claim 1 , wherein the inwardly inclined end section is of elastic or resilient design.

3 . The clamping sleeve as claimed in claim 1 , wherein
the clamping sleeve has, at least in some section or sections, a clamping sleeve projection on an end section that is axial with respect to the longitudinal axis, said clamping sleeve projection projecting radially outward with respect to the longitudinal axis.

4 . The clamping sleeve as claimed in claim 1 , wherein the clamping sleeve has at least one spring element on a lateral surface thereof.

5 . The clamping sleeve as claimed in claim 1 , wherein
the clamping sleeve has a mounting aid for positionally oriented mounting in the receiving opening.

6 . The clamping sleeve as claimed in claim 5 , wherein
the mounting aid is formed from a mandrel, which protrudes out of the receiving opening in a position of use and has a spirit level attached thereto.

7 . The clamping sleeve as claimed in claim 5 , wherein the mounting aid is formed from a mandrel with a template attached thereto.

8 . The clamping sleeve as claimed in claim 5 , wherein the mounting aid establishes positive engagement with the receiving device.

9 . The clamping sleeve as claimed in claim 5 , wherein the mounting aid is detachably connected to the clamping sleeve.

10 . A sensor arrangement, comprising:
a rotation sensor; a clamping sleeve, wherein a lateral surface of the clamping sleeve extends in a direction of the longitudinal axis, at least in some section or sections, the clamping sleeve is configured to be insertable at least partially into a receiving opening and to be holdable therein by frictional engagement, the clamping sleeve is configured so as to correspond to the rotation sensor to be mounted, such that, upon insertion of the rotation sensor into the clamping sleeve, positive engagement is established between the rotation sensor and the clamping sleeve, the rotation sensor is insertable at least partially into the clamping sleeve in the direction of the longitudinal axis, and
the rotation sensor has, at least in some section or sections, a rotation sensor projection which projects radially outward with respect to the longitudinal axis, thus enabling positive engagement to be established between the rotation sensor and the clamping sleeve via the rotation sensor projection when the rotation sensor is inserted into the clamping sleeve, wherein
the slot has a radially inwardly inclined end section on both sides of the slot extending in the direction of the longitudinal axis, and
the end sections are configured such that the positive engagement is established between the rotation sensor and the clamping sleeve via a rotation sensor projection of the rotation sensor when the rotation sensor is inserted into the clamping sleeve.

11 . The sensor arrangement as claimed in claim 10 , wherein
the rotation sensor projection extends in the direction of the longitudinal axis at least over a section which establishes the positive engagement with the clamping sleeve in a predetermined position of use.

12 . A rotation sensor system, comprising:
a rotation sensor; a receiving device having at least one receiving opening extending in a direction of a longitudinal axis, a clamping sleeve, wherein a lateral surface of the clamping sleeve extends in a direction of the longitudinal axis, at least in some section or sections, the clamping sleeve is configured to be inserted at least partially into the receiving opening and to be held therein by frictional engagement, the clamping sleeve is configured so as to correspond to the rotation sensor to be mounted, such that, upon insertion of the rotation sensor into the clamping sleeve, positive engagement is established between the rotation sensor and the clamping sleeve, and the clamping sleeve is held secure against rotation in the receiving opening at least via frictional engagement, and the rotation sensor is held secure against rotation in the receiving opening at least via positive engagement with the clamping sleeve, wherein
the slot has a radially inwardly inclined end section on both sides of the slot extending in the direction of the longitudinal axis, and
the end sections are configured such that the positive engagement is established between the rotation sensor and the clamping sleeve via a rotation sensor projection of the rotation sensor when the rotation sensor is inserted into the clamping sleeve.

13 . The rotation sensor system as claimed in claim 12 , wherein the receiving opening is a through opening in the direction of the longitudinal axis.
