Hollow Turbine shaft is a starting part for torque, revolutions or energy into another component of the transmission. It for a transverse mounted four speed automotive automatic transmission whenever were introduced to study its stresses. It has two splined parts at its ends and in between a bearing support mounting on the without splined part. The engine power has been transmitted by a drive link assembly to the input gear sets shaft. The study of stressed states of splined and without splined parts of hollow turbine shaft resulting in fatigue failure under two different working operating conditions of torque has been done. Also, hollow turbine shaft is loaded by two vertical loads which are coming from torque converter, friction viscous clutch and drive link and sprocket assemblies. From that, there are many critical combinations of forces (contact, normal, twist and shearing forces) applied on hollow input turbine shaft. The critical forces can be possibility exist many types of cracks for cross section of shaft they are: inclined (torsion stress), longitudinal and transverse (shear stress), and vertical (bending stress). The torsion, shear, bending, and compound stresses are studied theoretically in this article.
