309...321 gear units - male output shaft motor execution
These gear units are fitted with two spigots. When machining the coupling flanges, one spigot may be suffi-
cient if the output shaft is not subject to overhung loads or loads are less than 60% of the permissible load.
For heavier loads, the mounting must use both spigots on the gear unit.
If the gear unit is instead required to transmit high torque or is subject to heavy shock loads and inversions in
the direction of rotation, the counterflange must be drilled to accept the spigots.
At the time of installation, move the spigots mounted on the gear unit forward into the counterflange by an
amount equal to their diameter. See diagram below:
