Spiral bevel gear pairs (SBGs) play an important role in transferring power between non-parallel shafts in transmission systems. Their high contact ratio, makes SBGs smooth and quiet, allows them to withstand high levels of torque and power, however their complex geometry requires a careful consideration of the parameters that affect transmission efficiency and durability. Vibration is a major issue because it influences the stress distribution, contact pressure, and fatigue life of a geartrain. Several parameters, such as fluctuating mesh stiffness and transmission error in the gear mesh exert an important influence on vibration which is the major source of driveline noise.

The text provides an in-depth account of Stefano Odorizzi’s journey in founding and growing EnginSoft, our engineering company specializing in computer simulation and modelling. Established in 1984, EnginSoft overcame early challenges, such as the high cost of computing, to emerge as a leader in simulation services, particularly in the fields of mechanical engineering and computational fluid dynamics (CFD). The narrative highlights several key milestones in the company’s history.

CASE STUDY
Performing flow simulations to investigate the complex loss mechanisms caused by the interaction of the rotating oil ring within a piston in the inside of the roll of a calender, which is an important device of a paper machine. Hereby, the trends of the churning losses are determined for design improvement conducted by Voith Paper R&D.
