Abstract
An adjustable stroke mechanism has a housing with a central axis and a wall enclosing a cavity. At least one counterweight is movably disposed within the cavity. A mounting assembly is disposed within the cavity. The mounting assembly has a workpiece attachment mechanism. A stroke adjustor couples the at least one counterweight with the mounting assembly. The stroke adjustor enables the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.

An adjustable stroke mechanism for a random orbital machine comprising:
- a housing having a central axis and a wall enclosing a cavity;
- at least one counterweight movably disposed within the cavity;
- a mounting assembly disposed within the cavity, the mounting assembly including a workpiece attachment mechanism;
- a stroke adjustor coupling the at least one counterweight with the mounting assembly, the stroke adjustor including an axially movable element that is rotatable around the central axis, the stroke adjustor enabling the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.
A method of adjusting a stroke of a random orbital machine comprising:
- coupling an adjustable stroke mechanism to a random orbital machine, the adjustable stroke mechanism comprising:
- a housing having a central axis and a wall enclosing a cavity;
- at least one counterweight movably disposed within the housing;
- a backing plate mount assembly disposed within the housing;
- the backing plate mount assembly including a mechanism for attaching to a workpiece;
- a stroke adjustor coupling the at least one counterweight with the mounting assembly, the stroke adjustor including an axially movable element that is rotatable around the central axis;
- adjusting the stroke adjustor;
- moving the counterweight and mounting assembly with respect to one another;
- variably adjusting a distance between the counterweight and the mounting assembly;
- and
- variably adjusting a stroke radius of the mechanism to attach the workpiece with respect to the central axis of the housing.
A random orbital machine comprising:
- a motor, a power source and a switch for activating and deactivating the power source;
- a housing having a central axis and a wall enclosing a cavity;
- at least one counterweight movably disposed within the cavity;
- a mounting assembly disposed within the cavity, the mounting assembly including a workpiece attachment mechanism;
- a stroke adjustor coupling the at least one counterweight with the mounting assembly, the stroke adjustor including an axially movable element that is rotatable around the central axis, the stroke adjustor enabling the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.
