Similar to structures under tension or compression, two important mechanical properties of shafts under torque loads are shear stress and shear strain. Stress is a material's resistance to an applied force, and strain is the deformation that results from stress. Shear stress and shear strain (which are caused by torsional loads) occur when a ...

Hydraulic roller lifters operate with an internal cushion of pressurized oil and camshaft contact occurs thru a precision bearing on end of the lifter. The bearing rides on the camshaft lobe eliminating much of the friction and allows for smoother lifter to lobe contact. Roller camshafts are available in a wide variety of profiles.

Abstract. Roller bearing failures in wind turbines' gearboxes lead to long downtimes and high repair costs, which could be reduced by the implementation of a predictive maintenance strategy. In this paper and within this context, an acoustic-emission-based condition monitoring system is applied to roller bearing test rigs with the aim of identifying critical operating conditions before …

As the bearing deteriorates further, 1 x rpm sidebands develop, especially around the inner race frequencies. This is due to amplitude modulation as the defect (s) passes in and out of the "load zone." They can occur at +/- 1 x rpm, +/- cage frequency, or +/- ball spin frequency, depending on the situation.
