4-3-3: DRIVELINE APPLICATION
When you cannot directly mount the pump/
PTO is not feasible, you may use an auxiliary
driveshaft. To select the auxiliary driveshaft for
your installation, consider the following:
1. The driveshaft must be able to transmit
the necessary torque and RPM required.
Applications operating at less than 1200 RPM
may use a driveshaft constructed of solid bar
stock. More demanding applications will
require tubular shafts.
2. Avoid auxiliary driveshaft breakage and
personal injury by not exceeding the critical
speed of the selected driveshaft. Critical
speed is calculated using operating RPM,
shaft material and diameter, and installed
centerline to centerline length. Consult the
driveshaft manufacturer’s instructions for
specific information.
Normally, if calculations indicate a problem,
the use of multiple shafts and support bear-
ings is recommended.
3. The careful installation of a driveshaft with
concern for recommended driveline angles
will minimize vibration and provide trouble-free
operation.
4. The driveshaft must be capable of absorb-
ing any shock loads which may develop.
5. The driveshaft must be capable of varying
its length during installation and while trans-
mitting torque. This is refered to as “slip
movement”.
6. NEVER exceed the torque, length, angu-
larity and RPM limits specified by the manu-
facturer.
7. Only trained personnel using driveshaft
assembly equipment should fabricate a
driveshaft.
8. Balance tubular driveshafts.
