A high torsional stiffness low axial deflection stiffness flexible drive shaft apparatus is provided for driving a magnetic tape cassette and includes a drive shaft having opposite ends, a device for engaging the magnetic tape cassette and a pair of flexible diaphragms. A device is connected to ...
The principal design parameters for a shaft are weight, bending stiffness, bend point and torsional stiffness. For a given head weight, lightening the shaft reputedly makes the swing faster and hence gives some increase in ball speed and distance. Figure 14.3 has already indicated the violent for...

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...
engine crankshafts, cam-shafts, compressors) the torsional natural frequencies of the shaft must be significantly different to the torsional input frequency. This can be achieved by providing sufficient torsional stiffness so that the shaft's lowest natural frequency is much higher than the highest ...
1. Large torsional rigidity, high torque 2. Dedicated technical personnel can be on the go to provide design solutions 3. Factory direct sales fine workmanship durable quality assurance 4. Product quality issues have a one-year warranty time,...
Abstract During stretching of heavy forged shafts, there are three major factors that affect the stretching efficiency, including the rotation mode, anvil gap and feed length. Based on the research...
Condition-monitoring couplingsTorsionally stiff membrane couplings have no wearing parts; they need no lubrication or adjustment; they have a predictable high torsional stiffness that does not alter over a period of time and they have accessible low-stressed spacer tubes. These features make such coup...
For an ensemble and a flexible shaft with the same torsional stiffnesses, the flexural stiffness will also be equal, because the torsional stiffness follows the same formula as the bending stiffness. Thus, the first term on the right side of equation (4) reduces to approximately 1. The result...
For such an arrangement the bearing does not engage with the driving shaft in a portion of reduced torsional stiffness due to the axial bore within the end portion of the shaft 101. It is a benefit of an “in shaft” placement of the (angular) sensing element 106 as disclosed herein to...
