Double flank rolling test

The double flank rolling test is used for the simple and quick testing of gears . For this purpose, two gears, a master gear and the test specimen, are rolled without play, but with two flanks always in mesh. The basis of the test procedure is the fact that with perfect dimensional and shape accuracy of the gears, the center distance always remains the same during the generation. In order to measure fluctuations in the center distance, one axis of rotation is fixed and one is floating.

Both internal and external gears on gears and shafts can be checked with appropriate measuring devices . The advantage of the double flank rolling test is its simplicity, which allows it to be used in workshops and automatically integrated into production. However, the single-flank rolling test is more precisely and better adapted to practice .

Jump fi

The pitch jump is the greatest difference in pitch spacing that occurs during the duration of a tooth meshing.

Pitch error Fi "

The rolling error is the difference between the largest and smallest rolling center distance within a complete revolution. All individual errors are included in the result.
