Gear Pump
Alignment of the driving shaft and motor unit
A major influence on the leakage at the pump head and also on the life time
of the gear pumps is the accurate alignment of the gear motor unit.
Every gear motor unit must be perfectly aligned with a suitable alignment
device prior to the mounting of the gear pumps.
Alignment must be carried out when the beam is heated up to normal
operation temperature!
When aligning, the following values must not be exceeded:
S
Angular deviation of the driving shaft of ± 0,1° (approx. 1,75 mm lateral
deviation per 1000 mm)
S
Radial displacement of 0,2--0,4 mm of the driving shaft away from the
centre of the drive plug or the extended shaft of the pump.
S
Parallelism of the motor unit towards the clamping surface up to
0,25mm.
S
A displacement of the driving shaft of 2 mm away from the slot end of
the drive plug or at the end of the driving arbor should be strived for.
This ensures that no axial force is applied to the drive plug or driving
arbor through the driving shaft, and that the drive tang is simultaneously
sufficiently deep embedded in the drive plug for efficient transfer of the
drive torque.
