Abstract

Rotary hydraulic actuators and other rotating devices very often have potentiometers connected to the rotating shaft output of the actuator to determine position. It has been found that premature wear occurs within the port mechanism due to the eccentricities found in the pot shaft, the actuator shaft, and the actuator bearings. The potentiometer internal rotating mechanism absorbs these eccentricities since the mounting bracket is inflexible.

Flexible Potentiometer Bracket

Rotary hydraulic actuators and other rotating devices very often have potentiometers connected to the rotating shaft output of the actuator to determine position. It has been found that premature wear occurs within the port mechanism due to the eccentricities found in the pot shaft, the actuator shaft, and the actuator bearings. The potentiometer internal rotating mechanism absorbs these eccentricities since the mounting bracket is inflexible.

The potentiometer mounting bracket 14, shown in the figures, clamps to the potentiometer 12 and to the actuator plate 13. The potentiometer holding bracket 14 consists of a cylindrical shaped member 16 which fits around the outside periphery of the port near the top end thereof. The cylindrical shaped member 16 has flanged end portions 18 which face one another through which a nut and bolt 20, for tightening the bracket around the port, is located. A further bracket member 22 extends down from the cylindrically shaped member 16 and is offset therefrom. This offset bracket member has a flange 24 at the bottom thereof by means of which the entire port mounting bracket 14 can be secured to the actuator plate 13. This bracket 14 holds the port with respect to any rotation with the actuator shaft; however, the offset mounting member 22 is of a sufficient design and thickness to allow small flexure in all axes to accommodate the eccentricities encountered.
