What is torque in cylinder?
The torque on the rotating cylinder is symmetric with respect to eccentricity, and the torque increases with the magnitude of the eccentricity. The torque curves at different k can be collapsed onto one curve by the scaling factor (1/k − 1)1/2.
Is torquing important to spec?
When attaching a wheel to a vehicle, torque specifications are the amount of force recommended on the hardware to ensure proper installation. Following exact torque specifications matters for a number of reasons. Too much torque can result in overtightening, which has significant consequences.
How do you calculate the torque of a hollow cylinder?
To determine a fan or blowers horsepower when driving a hollow cylinder/shaft use the following equation….Motor Driving Hollow Cylinder Rotating Torque Equation and Calculator.
| T = | Required Torque, lb-ft |
|---|---|
| W = | Weight of object, lb |
| R1 = | Outside Radius of cylinder, ft |
| R2 = | Inside Radius of cylinder, ft |
Is the torque sequence?
Bolt tightening sequence or torque sequence is defined in the torque tightening procedure. Most company has their Flange bolt torque tightening procedure that used during construction and operation of the plant. Flange joints are torque tight with the help of a torque wrench (Manual or hydronic wrench).
What happens if you over torque a torque-to-yield bolt?
You can think of a bolt like a spring. As long as you don’t over-stretch the spring, it will always return to its original shape. If the bolt is over-torqued and stretched beyond its limit, this exceeds its yield strength which means it can no longer maintain the needed clamp load and must be replaced.
Should you reuse torque-to-yield bolts?
What is a torque-to-yield bolt? It is a one-time-use fastener that is designed to stretch during the torquing process (installation). Because of this stretching, the integrity of the bolt is compromised. These bolts cannot and should not be reused due to the stress caused to the bolt during its first installation.
What is the torque equation for the hollow shaft?
Torsion Resisting Moments from Shafts of Various Cross Sections
| Shaft Cross Section Area | Maximum Torsional Resisting Moment – Tmax – (Nm, lbf ft) |
|---|---|
| Hollow Cylinder Shaft | (π / 16) τmax ((2 R)4 – (2 r)4) / (2 R) = (π / 16) τmax (D4 – d4) / D |
| Ellipse Shaft | (π / 16) τmax b2 h |
| Rectangle Shaft | (2 / 9) τmax b2 h |
