A drive shaft assembly includes a first shaft member, a second shaft member, and a ball member. The first shaft member has a base that radially extends from a first shaft that extends along a first axis, and a finger that extends from the base and defines a first ball track. The ...
Torque is measured in degrees and describes the shaft’s torsional stiffness, or resistance to twisting. A high-torque shaft rating means more twist occurs compared to a low-torque shaft which better resists twisting. Golfers with a smooth swing may encounter a harsh feel and trouble starting th...
Options with backlash or that “wind-up” (low torsional stiffness) with changing speeds and/or directions limit a machine’s operating speed and throughput. Primary considerations for selecting a Flexible-Shaft Coupling include torque capacity, torsional stiffness, motion profile, shaft sizes, and ...
The flexurally elastic shaft with a high torsional stiffness comprises an elastomer, plastic or light-metal matrix reinforced by fiber material in various forms. Its shear-to-elastic modulus ratio referred to the material density is greater than 0.2 cm<3>/g when the shaft is used as a drillin...
Effect of the shaft stiffness on the inertial response of the fixed speed wind turbines and its contribution to the system inertia Future power system faces several challenges; one of them is the high penetration level of intermittent wind power generation, which provide small or even ... GL Fr...
Shafts used in power transmissions will invariably be either solid or thick-walled tubes. In gearboxes and similar assemblies, the shafts will be comparatively short and the design objective will be for these to be made as stiff as possible. Torsional stresses are unlikely to be of major concer...
The torsional vibration inherent characteristics in the propulsion shaft system are mainly determined by the torsional stiffness and rotational inertia of the system. To ensure the consistency of inertia and stiffness before and after the simplification, the propulsion shaft system is simplified into the...
