7.4.2 Applications with a vertical direction of movement
For this model a tool is positioned by means of a toothed belt. A motor or geared motor with or with-
out a downstream speed-transforming gear travels along a fixedly clamped toothed belt. A tool or
payload m
L
is fastened to the motor. The drive is operated via guide (coefficient of friction μ
Gdn
).
• The positioning process can be carried out via time-controlled path generators (positioning soft-
ware) or via path-controlled path generators (electronic cams).
• The movement is carried out within one of the three dimensional axes (horizontally x, y, and
vertically z), or within a plane inclined to the horizontal by the angle β (0 ... 90°).
Beating of the belt pulley
The toothed belt either is mounted directly to the motor shaft/gearbox shaft, or by means of a
transmission gear (internal bearing support):
• In the case of arrangement A the bearing of the motor or gearbox has to be checked separately
with regard to radial forces at the output end (see the following section). This function currently
is not contained in the DSD yet.
