drive shaft coupling failure

Had to replace my factory rear driveshaft coupling recently has a few small cracks due to age. A coupling is a very useful component in industry.

7 Tube Yoke and Slip Yoke.

. Drive Shaft Coupling Failure - To avoid premature coupling failure it is critically important in design selection to match the correct coupling to the misalignment condition or. Most drive shaft manufacturers recommend that tube yoke circle welds be started in line with the tube. Noise at the coupling.

Therefore a shaft coupling must be used to absorb such mounting and. Coupling selection involves a number of design criteria including. It is a major component of the drive shaft and coupling shaft linked with the housing on the center bearings.

Thats because the failure typically provides strong clues to the type and magnitude of forces. Up to 50 of damage to rotating equipment is. Improper welding when the drive shaft is assembled can cause tube yoke failures.

Discussion Starter 1 Feb 6 2015. This is one of the most common causes of a coupling failure. It also increases wear and the risk of mechanical failure due to the induced stress of the misalignment.

Symptoms of misalignment include the following. Coupling flexibility for accommodating excessive mis-alignment as flexing of the coupling and the shaft will impose forces on the drive and driven equipment bearings. This is sometimes referred to as a fusible link function being.

Powdered rubber particles or leaking lubricant directly below the coupling depending upon. The flip side of this is the application where the user actually wants the coupling to disengage the drive if the element should fail. Component failure of the drive shaft or the motor and transmission mounts can cause vibration.

Misaligned pump or motor shafts lead to damage or breakage of the couplings. Joined Apr 20 2007. The shaft couplings will also need to be undone for the same reason.

At Crane Engineering we find the root cause of coupling failure ladders up to one of the following reasons. It is a device which is used to connect two shafts together at their ends with the aim of transmitting power. Install and remove these shaft couplings without disconnecting the shafts motors and other attached components theyre made in two pieces so you dont.

For most machine shafts however analysis should be relatively straightforward. Application torque misalignment stiffness inertia RPM shaft mounting environmental factors space limitations. In case of driveshaft failure you must.
