Abstract
A machine for processing gears, such as by testing and lapping, which can accommodate a wide range of gear pair shaft angles (less than, equal to, and greater than ninety degrees) while providing improved machine stiffness and an enhanced arrangement of machine elements.
Claims22
A gear processing machine comprising:
- a base portion integral with a stationary column extending upward from said base portion;
- a first spindle movably mounted to said column, said first spindle having an axis of rotation;
- a stationary inclined bed portion located on said base portion, said inclined bed portion being attached to said column;
- a second spindle movably mounted to said inclined bed portion, said second spindle having an axis of rotation;
- said first spindle and said second spindle being translatable with respect to one another in up to three different directions.

A gear testing or lapping machine comprising:
- a base portion integral with a stationary column extending upward from said base portion;
- a first slide positioned on said column, said first slide being movable in a first vertical direction, Y;
- a first spindle movably positioned on said first slide, said first spindle being movable in a first horizontal direction, X, and having an axis of rotation, A;
- a stationary inclined bed portion located on said base portion, said inclined bed portion being attached to said column;
- a second slide positioned on said inclined bed portion, said second slide being movable in a second horizontal direction, Z;
- a second spindle movably mounted to said second slide, said second spindle having an axis of rotation, C;
- said second spindle being angularly movable around a pivot axis, B, whereby said first spindle axis, A, and said second spindle axis, C, are positionable with respect to one another to effect testing or lapping of gear pair members at predetermined angles with respect to one another, said angles being at least one of less than, equal to, and greater than ninety degrees with respect to one another.
