Abstract

A device for mounting a sensor on a device being subjected to torque such as a shaft or plate in the form of a retaining ring having an opening or chamber sized to hold the sensor. The ring has a first open end for insertion of the sensor into the chamber or opening and a second end having a lip for retaining the sensor in the opening. The second end has an opening for the sensor wires or other connecting elements. The ring has threads on the outer periphery of the retaining ring for engaging similar threads on the device being subjected to torque.

Claims

1. A device for mounting a sensor on a device being subjected to torque, comprising:

a sensor having a contact portion thereof for contact with a device subjected to torque;

a retaining ring having an opening sized to hold said sensor, said ring having a first open end for insertion of said sensor and a second end having a lip portion for retaining said sensor in said opening;

a threaded portion on the outer periphery of said retaining ring, said threaded portion being adapted to engage a threaded recess in said device being subjected to torque,

whereby said sensor is attached to said device by threading said retaining ring onto said threaded recess on said device to maintain contact between said sensor and said device.

2. The device of claim 1, where said device is a rotating shaft.

3. The device of claim 1, wherein said device is a plate subject to torque.

4. The device of claim 3, wherein said second end in said retaining ring includes an opening for access to connecting wires on said sensor.

5. The device of claim 1, wherein said retaining ring includes a fastener for tightening said ring in said recess.

6. The device of claim 1, which further includes an adhesive on said sensor contact portion.

7. A device for mounting a sensor on a device being subjected to torque, comprising:

a sensor having a contact portion thereof for contact with a device subjected to torque;

retaining ring means for mounting said sensor means and having an opening sized to hold said sensor, said ring means having a first open end for insertion of said sensor and a second end having lip means for retaining said sensor in said opening;

attachment means on the outer periphery of said retaining ring means for engaging said device being subjected to torque,

whereby said sensor is attached to said device to maintain contact between said sensor and said device.

8. The device of claim 7, where said device is a rotating shaft.

9. The device of claim 7, wherein said device is a plate subject to torque.

10. The device of claim 7, wherein said retaining ring means includes an opening for access to connecting wires on said sensor.

11. The device of claim 7, which further includes an adhesive on said sensor contact portion.

12. The device of claim 7, wherein said retaining ring means includes fastener means for tightening said ring means in said recess means.

13. A method for mounting a sensor on a device being subjected to torque, comprising the steps of:

placing a sensor having a contact portion thereof for contact with a device subjected to torque in a retaining ring having an opening sized to hold said sensor, said ring having a first open end for insertion of said sensor, a second end having a lip portion for retaining said sensor in said opening and a threaded portion on the outer periphery of said retaining ring,

forming a threaded recess in said device being subjected to torque; and

threading said retaining ring onto said threaded recess on said device to maintain contact between said sensor and said device.

14. The method of claim 13, where said device is a rotating shaft.

15. The method of claim 13, wherein said device is a plate subject to torque.

16. The method of claim 13, wherein said second opening in said retaining ring includes an opening for access to connecting wires on said sensor.

17. The method of claim 13, which further includes the additional step of placing an adhesive on said sensor contact portion.

18. The method of claim 123 wherein said retaining ring includes a fastener for tightening said ring in said recess.
