Telescopic Drive Shafts

Custom Drive Shafts Compensate for Distance and Misalignment

Belden Universal offers telescopic drive shafts (also called cardan shafts) in a variety of design types, such as Heavy Duty, Stainless Steel and Leveler Strength.

Drive shaft u joints, also called articulated shafts, are shafts that include two universal joints. The simplest type of drive shaft contains a joint at each end. The configuration is essentially an extended double joint for overcoming distances and offsets between the drive and the driven load. Drive shaft joints also provide a solution for bridging angular misalignment.

Telescopic Drive Shafts

Cardan shafts can contain a telescopic middle element that enables quicker and simpler repositioning than possible with a rigid two-joint shaft. They allow for easy length adjustment in axial misalignments.

Spring-Loaded, Quick-Change Shafts for Reducing Downtime

Spring-loaded drive shaft joints consist of two back-to-back single universal joints connected with a spring-loaded intermediate shaft. It allows the drive shaft to be quickly removed and replaced without tools. Pinning of outer yokes is not required because the spring tension on the intermediate shafts holds the quick-change universal joint secure at each end.

Fail-Safe Stop Solution

Spring-loaded drive shaft joints can be customized to include a fail-safe solution. If the application seriously exceeds the joint's rated torque capacity, the drive shaft can be designed to fail and stop in a safe fashion, without damaging the motor.
