9.11 Transmission Definition
To avoid abnormal radial loads on the shaft and its related bearing, please comply with the following indications:
a) Use pulleys with race dimensions prescribed / recommended by the belt manufacturer. Should no
indications be supplied, please see fig. 9 and the table in fig. 10.
Dimensions (in mm)
b) Use high efficiency belts - for example XPB instead of SPB; this will allow to use a lower number of belts to
transmit the same power, and consequently a minor distance of the resultant from the shaft shoulder (PTO),
“a” in fig. 11.
The pulley’s minimum diameter must be respected.
Do not used banded v-belts.
