How big is the friction on a flywheel?
The outer diameter, the area behind the friction surface, is cut to a thickness of .500″ The flywheel is resurfaced first, the friction surface is inspected, then the back side is cut to match. If the resurface requires too much material to be removed, then it is rejected for lightening.
What should be considered when designing a flywheel?
Flywheel design doesn’t stop with that. Its size, shape and material density / mass and maximum stresses are also to be taken into account while designing a flywheel. Which we will discuss in this part. The material of flywheel on most applications will be either cast iron or cast steel. The Density of the materials (d) is as follows.
Is it normal for a flywheel to crack?
If it was full thickness on the friction surface side, there is a 50/50 chance this crack would clean up. But you can see that the friction surface is already down below the cast surface. It is junk. This flywheel only has heat marks on it. This is normal for anyone having fun with their car. This is no problem.
How to calculate the mass of a flywheel?
Step-2: Calculation of the flywheel mass. We already know how to get the mass moment of inertia of a flywheel (I) required for a specific application. Another equation for calculating the mass moment of inertial (I) is: I = m* K 2. Or, I = m* (R1 2 + R2 2)/2………………..eq.2.1. R2 = 400 mm (assumption)
Which is the best specification for a flywheel?
The flywheel “step” specification is a very important factor for smooth and proper operation of any clutch. When having your existing flywheel machined please keep in mind there are normally 2 types of machines used.
What is life expectancy of Spec Clutch flywheels?
The Super Twin offers near-stock drivability, tremendous life expectancy, a no-shimming/setup bolt-in installation and maintenance free operation. Multi-disc clutch and flywheel assemblies for limited street, drag race and road race applications.
What’s the difference between flywheels 3921263 and 3906807?
The only difference in 3921263 & 3906807 is the position of the ring gear on the flywheel. This flywheel has very thick ring gear, that is it’s characteristic. Flat 160 tooth 4600320051 Bearing Spacer. 206 bearing.
Why are spec billet flywheels used in cars?
SPEC billet flywheels are manufactured and developed for specific driving environments and recommended based on how each car reacts to changes in rotating mass. Stock appearing aluminum pressure plates allow for quicker revs, more horsepower and increased engine reliability.
