Abstract

A rotary motor with a counterbalanced torque arm adapted to be mounted within an auger housing. The torque arm is mounted on the stationary cylinder block of the motor which extends radially outwardly from the access of the cowling and is attached to the auger housing. The torque arm includes a pair of diametrically opposed torque arm members which support pairs of cylinders. The cylinders engage the housing and are interconnected such that diametrically opposed pairs of cylinders are in fluid communication. Accordingly, rotational torques exerted on the torque arm by the cylinder block, for auger screw rotation both in the clockwise and counterclockwise directions, are born equally by the opposing torque arm members.

Claims

1. For use with a rotary motor of a type having a rotating part for transmitting torque and a stationary part, a counterbalanced torque arm system comprising:

a counterbalanced torque arm mounted on said stationary part and including a first and a second arm means;

two pairs of discrete opposing cylinder means, each of said pairs being positioned in opposing relation within a different one of said arm means, and each of said cylinder means having a stub shaft protruding from an associated one of said arm means, said shafts being shaped to connect said arm means to associated stationary support structure, whereby reactive radial loads from said rotary motor are transmitted through said torque arm, said cylinders and said stub shafts to said associated stationary support structure.

2. The torque arm system of claim 1 wherein said arm means includes means for distributing said reactive radial loads evenly between said arm means.

3. The torque arm system of claim 2 wherein said distributing means includes means for interconnecting said cylinder means such that working fluid is exchanged between said cylinder means on different ones of said arm means.

4. The torque arm system of claim 3 wherein said arm means includes mounting blocks attached to said arm means;

and said cylinder means includes pairs of opposing cylinders mounted within said mounting block such that only stub shafts thereof protrude from said mounting blocks.

5. The torque arm system of claim 4 wherein said cylinder means of said first arm means are interconnected with diametrically opposite ones of said cylinder means on said second arm means, whereby reactive radial loads are equalized between said arm members.

6. The torque arm system of claim 5 wherein said arm means are positioned diametrically opposite to each other relative to a rotational axis of said motor.

7. The torque arm system of claim 1 further comprising means for fluid pressurizing said cylinder means such that said stub shafts independently extend to contact said associated support structure.
