Gearing layout for machine tool - has single intermediate insert sleeve that fits between input gears and each output shaft

摘要

The layout is for one power input shaft with two or more output shafts running parallel to one another. The gears on the output shaft are removable so that the gear ratios can be changed. The output shafts (7, 7a) are connected to the input shaft (1) via a single piece gear unit that ca be detached from the machine housing. The gear unit has a casing (1) with a gearwheel pair (3, 4, 3a, 4a) running on each output shaft (7, 7a) with an insert sleeve (8) between each gearwheel and each output shaft. This has followers (8a, 8b) which couple with the gearwheels and output shafts and fits in through openings in the gear case.
