Abstract

A dielectric insulating assembly arranged to be positioned between a drive shaft and a driven shaft of a motorised drive assembly. The assembly includes dielectric insulation between the drive shaft and the driven shaft and plurality of electrically non-conductive fastener elements configured to connect the drive shaft to the driven shaft and the dielectric insulation therebetween, in torque transfer engagement, the fasteners located around an outer boundary of the dielectric insulation.

First claim

The invention claimed is:

1. A dielectric insulating assembly arranged to be positioned between a drive shaft and a driven shaft of a motorised drive assembly, the assembly comprising:
a disk of dielectric insulation between the drive shaft and the driven shaft;
a plurality of electrically non-conductive fastener elements configured to connect the drive shaft to the driven shaft and the dielectric insulation therebetween, in torque transfer engagement, the fasteners located around an outer boundary of the disk of dielectric insulation; and
fastener elements each comprise a tie having a loop at each end, the loop at one end configured to be attached and encircle, in use, to a pin on the drive shaft and the loop at the other end configured to be attached and surround a pin on the driven shaft.

2. The assembly of claim 1 , wherein the plurality of fasteners are joined into a single fastener unit to be mounted between the drive shaft and the driven shaft.

3. The assembly of claim 2 , wherein the fastener unit is in the form of a belt comprising a plurality of fastener ties connected together by one or more strings.

4. The assembly of claim 1 , wherein the disk is a disk of ceramic material.

5. The assembly of claim 1 , wherein the fasteners are aramid fiber fasteners.

6. The assembly of claim 1 , wherein the fasteners are arranged to provide a compressive force against the periphery of the dielectric disk.

7. A ball shaft assembly comprising:
a ball shaft as a driven shaft;
a cam shaft as a drive shaft, and
a dielectric assembly as claimed in claim 1 fitted between the ball shaft and the cam shaft.

8. The assembly of claim 7 , further comprising a motor arranged to drive the ball shaft via the cam shaft, the dielectric assembly located between and in torque transfer engagement with the ball shaft and the cam shaft.

9. The assembly of claim 7 , further comprising a handle to manually rotate the ball shaft.

10. The assembly of a claim 8 , wherein the motor is an electric motor.

11. A water supply system including:
the assembly of claim 7 .

12. The water supply system of claim 7 , wherein the water supply is an aircraft water supply system.
