Abstract

An integration element including a shaft and a housing, wherein the housing includes a passage for the shaft and the shaft includes connecting elements on the shaft ends which are accessible from outside the housing, these elements providing a rotationally-fixed connection to connecting shafts. The housing has at least one connection for fastening to a connection structure and the shaft together with the housing delimits a measuring equipment space for receiving measuring equipment. The housing is formed by at least two housing parts detachably connected to each other, said housing parts being designed to be separated around the full extent of their circumference surrounding the shaft to allow access to the measuring equipment space. The housing has bearing seats for shaft bearings and these shaft bearings support the shaft in a rotatable manner with respect to the housing.

First claim

The invention claimed is:

1. An integration element, comprising:
a shaft and a housing,
the housing has a passage for the shaft,
the shaft has shaft ends that are accessible from outside the housing, and the shaft ends have connection elements for connection to connection shafts in a rotationally secure manner,
at least one connection on the housing for securing to a connection construction,
the shaft delimits together with the housing a measuring equipment space for receiving measuring equipment,
the housing is formed by at least two housing components which are releasably connected to each other,
the housing components are constructed so as to be separable over a periphery thereof over a full extent around the shaft in order to enable access to the measuring equipment space,
bearing seats in the housing and shaft bearings located in the bearing seats, and,
the shaft bearings rotatably movably support the shaft with respect to the housing,

wherein the housing components each have one of the bearing seats for one of the shaft bearings, and each of the shaft bearings comprises an inner ring and an outer ring and rolling or sliding members which are arranged between the inner ring and the outer ring, and the outer ring is supported in the bearing seat.

2. The integration element as claimed in claim 1 , wherein the shaft is formed by a measurement shaft, and measuring equipment is provided in the measuring equipment space for contactless detection of at least one physical measurement variable to be measured on the measurement shaft.

3. The integration element as claimed in claim 1 , wherein the at least two housing components are structurally identical.

4. The integration element as claimed in claim 1 , wherein the shaft bearing is sealed with respect to the housing environment by a seal.

5. The integration element as claimed in claim 1 , wherein the housing has at least one interface for connection to a sensor which is integrated in the measuring equipment space in order to transmit a physical measurement variable.

6. An integration element, comprising:
a shaft and a housing,
the housing has a passage for the shaft,
the shaft has shaft ends that are accessible from outside the housing, and the shaft ends have connection elements for connection to connection shafts in a rotationally secure manner,
at least one connection on the housing for securing to a connection construction,
the shaft delimits together with the housing a measuring equipment space for receiving measuring equipment,
the housing is formed by at least two housing components which are releasably connected to each other,
the housing components are constructed so as to be separable over a periphery thereof over a full extent around the shaft in order to enable access to the measuring equipment space,
bearing seats in the housing and shaft bearings located in the bearing seats, and,
the shaft bearings rotatably movably support the shaft with respect to the housing,
wherein the housing components each have a cylindrical cover, and the housing components are connected to each other at mutually facing end faces of the cylindrical covers.

7. The integration element as claimed in claim 1 , wherein at least one of the housing components has a radially outer securing flange for securing to the connection construction and the bearing seat in order to receive the shaft bearing.

8. The integration element as claimed in claim 5 , wherein the two housing components each have a securing flange and the at least one interface is arranged between the securing flanges.

9. The integration element as claimed in claim 1 , wherein the shaft together with the housing and together with the connection construction delimits the measuring equipment space for receiving measuring equipment.

10. The integration element as claimed in claim 1 , wherein at least one of the shaft bearings is secured by securing rings against axial displacement.

11. An integration element, comprising:
a shaft and a housing,
the housing has a passage for the shaft,
the shaft has shaft ends that are accessible from outside the housing, and the shaft ends have connection elements for connection to connection shafts in a rotationally secure manner,
at least one connection on the housing for securing to a connection construction,
the shaft delimits together with the housing a measuring equipment space for receiving measuring equipment,
the housing is formed by at least two housing components which are releasably connected to each other,
the housing components are constructed so as to be separable over a periphery thereof over a full extent around the shaft in order to enable access to the measuring equipment space,
bearing seats in the housing and shaft bearings located in the bearing seats, and,
the shaft bearings rotatably movably support the shaft with respect to the housing,
wherein a positioning element prevents the relative rotation of a housing component in relation to the releasably connected other housing component.

12. A drive train having the integration element as claimed in claim 1 , wherein the shaft is coupled to a shaft of the drive train in a rotationally secure manner.

13. The integration element as claimed in claim 6 , wherein the shaft is formed by a measurement shaft, and measuring equipment is provided in the measuring equipment space for contactless detection of at least one physical measurement variable to be measured on the measurement shaft.

14. The integration element as claimed in claim 11 , wherein the shaft is formed by a measurement shaft, and measuring equipment is provided in the measuring equipment space for contactless detection of at least one physical measurement variable to be measured on the measurement shaft.

15. The integration element as claimed in claim 6 , wherein the at least two housing components are structurally identical.

16. The integration element as claimed in claim 11 , wherein at least one of the shaft bearings is secured by securing rings against axial displacement.

17. The integration element as claimed in claim 6 , wherein at least one of the housing components has a radially outer securing flange for securing to the connection construction and the bearing seat in order to receive the shaft bearing.

18. The integration element as claimed in claim 6 , wherein the housing has at least one interface for connection to a sensor which is integrated in the measuring equipment space in order to transmit a physical measurement variable.

19. The integration element as claimed in claim 11 , wherein the housing has at least one interface for connection to a sensor which is integrated in the measuring equipment space in order to transmit a physical measurement variable.

20. The integration element as claimed in claim 11 , wherein the shaft together with the housing and together with the connection construction delimits the measuring equipment space for receiving measuring equipment.
