Causes of the Shaft Failure
The problem of failure of Gears and Shafts is not faced every day. But if it happens, it becomes very difficult to determine the cause of that failure. Here is the list of some of the causes of the failure and breaking of shafts.
- Transverse Vibrations: It is caused due to the unbalanced drive shaft which results in the damage to the shaft. Balance weights are also missed which results in a transverse vibration which will occur once in the drive shaft due to the revolution.
- Critical Speed Vibrations: When a drive shaft operates at an RPM which is too high in relation to the mass, diameter, and length, these type of vibrations are occured.
- Torsional Vibrations: These vibrations are caused because of a shaft which is not in phase along with its design specifications and due to excessive u-joint angles. Torsional vibration issues can be caused because of the yoke which is outside of the design and faced by a spline.
- Component Failure: This type of failure in the drive shaft can cause vibration. It is also due to the mounting of the transmission and the motor. The best example for this could be the failing of the u-joint.
While the processing of the shaft is going on, various stress raisers are created which hampers the successful operation of Gears and Shafts. It may be also caused due to many other situations like having an excessive load which may be imposed on the actual operating load. This unexpected load may be two or three times more than the actual one.
