Driveshaft Manufacturing

As a leading driveshaft manufacturer, our driveline department integrates certified machine welding with state of the art equipment to provide the highest quality driveshafts. Our OEM driveshaft manufacturing includes assisting engineering and project management teams during the R&D phase through production with minimal lead time.

Below you will find useful tools to guide you. Feel free to contact us by uploading any prints or specs for you application, we would love to partner with you on your next build.

Technical Requirements

Several calculations are required to verify the appropriate driveshaft(s) for your specific application. Most of these center around torque and RPM of the driveshaft itself. Below is an explanation of the torque calculation requirements:

Torque Calculations

• Low Gear Torque – Calculation takes the engine torque and converts to the torque on the driveshaft by multiplying the gear ratios of your transmission, torque converter, and transfer case.
• Wheel Slip – Calculates the torque from the wheels based on the inverse relationship between axle capacity * ratio and tire radius.
• Grade Torque – Calculates the torque on the driveshaft on a graded plane. This is the inverse relationship of (gross vehicle weight * tire radius) over the axle ratio.

RPM Calculation

• Critical Speed – Calculation of Critical RPM is based on the type of material of the driveshaft. It is the inverse relationship of tube diameter and length of the driveshaft.
• Adjusted Critical Speed – Corrects the critical speed to the maximum safe operating speed for safety and movement in the shaft. For assistance, please refer to Dana's Driveshaft Safe Operating RPM Calculator

The above calculations allow you to choose the series of the shaft needed for your application. It will also provide the number of shafts required. For the detailed calculations and additional variables to consider please review Dana's Application Guidelines.

Measuring the Driveline Angle

• You need to have a protractor or digital Angle Master.
• You must measure from a flat surface, the angle on both sides of each intersection from the transmission through the differential.
• Angles can be up or down. If slope descends from front to rear the angle would be down. If in ascends the angle would be up.
• If the angles on both sides of the coupling slope in the same direction (Up, Up or Down, Down), then subtract the lowest number from the highest number
• If the angles on both sides of the coupling slope in the opposite direction (Up, Down or Down, Up), then add the numbers together. For assistance, you can refer to Dana's Driveline Operating Angle Calculator
