Führungseinrichtung für zusammengesetzte Bewegungen

摘要

In a composite motion guide device comprising a drive shaft having a spiral screw groove grooved on the outer circumferential face and a linear spline groove grooved thereon in the axial direction to cross the screw groove, a rotatable screw-rotor covering the drive shaft and screwing the screw groove thereon, and a rotatable spline-rotor covering the drive shaft and engaging with the spline groove thereon, the screw-rotor and the spline-rotor can be selectively rotated by a single driving device with a clutch. Therefore, the structure of the device can be simpler, so that a light, small and economical composite motion guide device can be provided.
