An auxiliary power shaft transmits torque from the power source to the driven accessory.
The shaft must be capable of transmitting the maximum torque and R.P.M. required of the
accessory, plus any shock loads that develop.
An auxiliary power shaft operates through constantly relative angles between the power source
and the driven accessory, therefore, the length of the auxiliary power shaft must be capable of
changing while transmitting torque. This length change, commonly called “slip movement”, is
caused by movement of the power train due to torque reactions and chassis deflections.
Joint operating angles are very important in an auxiliary power joint application. In many cases,
the longevity of a joint is dependent on the operating angles. (See chart below)
This information is limited to 1000 through 1310 series applications. For applications requiring a series
larger than 1310, contact your local Chelsea distributor
.
Determining Shaft Type
1) Solid or tubular?
a) In applications requiring more than 1000 R.P.M. or where the application necessitates a highly
bal anced auxiliary power shaft, a tubular shaft should be used.
b) Spicer’s solid shafting auxiliary power joints are designed for 1000 or less R.P.M. intermittent
service such as:
Driving small hydraulic pumps
Driving winches
Driving low speed product pumps
2) Joint Series should be determined using the chart on the following page.
