4.2 ZRL graph of torque
Torque/speed graph for section selection of open-ended optibelt ZRL-M (z
emax
= 12)
and
optibelt ZRL-V joined endless timing belts (z
emax
= 6)
In each case, the maximum width from the combination of standard
timing belts and standard pulleys has been assumed (see
Table 4.2).
The speed of the ZRL-V timing belt should not exceed 2 m/s. Further
notes will be found on page 37.
