Advance drive of slide units on machine tool - involves rapid movement and slow movement drive with drive and driven shafts aligned in common housing

摘要

All drives (2,3) run parallel to one another, and the drive and driven shafts (10,13,19) are aligned in a common housing (1). The slow movement drive shaft (19) is located in the rapid movement drive shaft (10). The gearwheel block (12) which is two-staged and is located on a crank pin in the first stage meshes with the inner toothing (11) of the hollow shaft (10), and in the second stage meshes with the inner toothing (14) of the driven shaft (13). The gearwheel block (12) in both stages has differing tooth counts. Both motors (4,15) work simultaneously in the rapid movement, both only one (15) works in the slow movement. USE/ADVANTAGE - For machine tools with advance drive for slide units, involving all drives running parallel to each other, with the drive and driven shafts aligned in a common housing.
