    摘要: An intermittent drive for a single-element printing typewriter, calculator or similar machine. The drive comprises a drive shaft couplable via a cycle clutch to a driven shaft and a governor disposed on the driven shaft to couple it with and maintain it at the same speed as the drive shaft during the clutch cycle. The governor comprises a friction wheel having a generally circular cross-section provided with flattened portions. During the clutch cycle, when the clutch engages the driven shaft, the friction wheel contacts a roll fixed to the drive shaft preventing the driven shaft from leading the drive shaft in response to reflected forces. At the end of the clutch cycle, when the clutch is disengaged, the friction wheel has rotated so that a flattened portion of the friction wheel faces the roll, and driven shaft is free from the rotation of the drive shaft.
