Abstract
A gauge for checking the quality (accuracy; tolerance: trueness) of gear teeth is provided with a set of gauging teeth which, when the gauge is used, mesh with the teeth to be checked. This effects automatic alignment of the actual contact pins relative to the teeth to be checked.
Claims16
A gauge, particularly for inspecting and indicating the quality of gear teeth on a workpiece, comprising
- a hollow elongated member having an axis and a leading end portion provided with inner and outer circumferential surfaces;
- a set of gauging teeth on at least one of said surfaces and shaped and dimensioned to mate precisely with the teeth to be inspected on a workpiece;
- a test element located within the confines of said one surface and having at least one component movable into and out of testing engagement with a tooth on the workpiece;
- said one surface having at least one slot extending in lengthwise as well as in radial direction of said axis;
- and
- means mounting said test element so that said component is located in said slot with freedom of movement in at least one of said directions.
A gauge, particularly for inspecting and indicating the quality of gear teeth on a workpiece, comprising a hollow member having an axis and including a circumferential wall having an outer surface, a discrete ring part surrounded by said wall, and an annular member surrounded by said ring part and having an inner surface;
- a set of gauging teeth provided on said inner surface and shaped and dimensioned to mate precisely with the teeth to be inspected on a workpiece;
- a test element located within the confines of said inner surface and having two components movable into and out of testing engagement with a tooth on the workpiece, said inner surface having two slots extending in lengthwise as well as in radial direction of said axis and being located opposite each other with reference to said axis;
- and means mounting said test element so that each of said components is located in a different one of said slots with freedom of movement in at least one of said directions.
