Page 30: Shaftmounted Gear Unit With Hollow Shaft And Shrink Disk
Shaftmounted gear unit with hollow shaft and shrink disk The end of the drivenmachine shaft (material C60+N or higher strength) should have a centring means to DIN 332 Form DS (with thread) in its end face (for connecting dimensions of the drivenmachine shaft, see dimensioned drawing in the gearunit documentation). -
Page 31: Shrink Disk
6.3.2 Shrink disk The shrink disk realizes a pressfit connection between a hollow shaft and a stub or drivenmachine shaft, in the following called "stub shaft". The interference fit can transfer torques, bending moments and forces. The jointing pressure between the hollow and stub shafts generated by the shrink disk is essential for the torque and/or force transmission. - Page 32 M 16 M 33 2650 The shrink disk has been identitymarked on the outer ring (4). In case of contacting Siemens this identification must be referred to. For safety reasons, a protective cover should be fitted to prevent contact! This cover must be applied after completion of all works on the shrink disk.

Page 33: Demounting The Shrink Disk
6.3.2.2 Demounting the shrink disk • Remove the protective cover. • Remove any rust deposits from the shaft and the hollow shaft. Under no circumstances must the tensioning bolts be unscrewed one after the other. • Undo all tensioning bolts one after the other by approx. 1/4 turn. The stored energy of the outer ring is slowly loosened during disassembly via the bolts to be loosened. -

Page 37: Alignment
The elements must be pulled smartly onto the shaft as far as stated on the dimensioned drawing prepared in accordance with the order. Fit the coupling with the aid of suitable fitting equipment (see item 6.7). The parts must not be driven on by abrupt force, as this may damage the gear unit. The shaftsealing rings and running surfaces of the shaft must not be damaged when pulling in the coupling parts. -
Page 38: Couplings, Clutches
For permissible alignment errors in case of couplings supplied by Siemens, please refer to the operating instructions manuals for the couplings. If you use couplings manufactured by other manufacturers, ask these manufacturers which alignment errors are permissible, stating the radial loads occurring. -
Page 39: Gear Unit With Addon Oilsupply System
Alignment has to be done in two axial planes arranged perpendicularly to each other. This can be done by means of a ruler (radial misalignment) and feeler gauge (angular misalignment), as shown in the illustration. The aligning accuracy can be increased by using a dial gauge or a laser alignment system. Fig. -
