Belt drive

In linear units, toothed belts are used as the drive means for positioning and handling tasks. Compared
with conventional chain drives, the belt drive is zero maintenance and needs no lubricating. In a
circulating belt drive, there is a distinction betwee

n a stationary Ω-drive and a travelling Ω-drive for

large distances. In the linear units LEZ 1

– LEZ 2 – LEZ 3 – LEZ 9, only the recirculating belt drive

modus  operandi  is  used.  Linear  guide  rails  also  facilitate  support  for  the  top  trunk,  which  leads  to
improved positioning accuracy with large axis lengths.
On  the  inside  of  the  belt,  there  are  rubber  teeth  which  engage  in  a  gearwheel.  The  positive  fit  of  the
gearing means that high forces can be transferred. Because the teeth preclude slippage, toothed belts
are used to control or position the shaft slot/trolley.
The actual force is transferred by a rope under tension embedded in the toothed belt.
