ABSTRACT:
A correction device for the rolling tape tension on a gear grinding machine, especially a form grinding machine for spur and helical cylindrical gears, comprising tapes subjected to an initial basic tension at rest, the tapes being attached at one end to a rolling block, and there occurring between the rolling block and the tapes a relative rolling action. The tapes are attached at their other end to a tape stand which is movable to-and-fro. At the tape stand intermediate pieces or tape clamps are mounted on a device which imparts an additional torque on the rolling block. A gauging device measures the tension in the rolling tapes and compares it with the initial tension of the system at rest. In the event of a decrease in the tape tension relative to the initial tension on one side of the rolling block such gauging device actuates the device which produces an additional torque on the opposite side of the rolling block until the gauged tension on the one side of the rolling block again attains the level of the initial tension.
