AI Thread Summary
Suitable materials that can withstand 200°C while producing low noise when meshing with other parts are being sought. Polymers like cast nylon and HDPE are considered, but they do not possess similar properties to steel, particularly in tensile strength. The discussion suggests that a redesign of gear teeth engagement may be a more effective solution for noise reduction than solely focusing on material selection. Clarification on the specific application and noise sources is also requested to better address the issue. Overall, finding a balance between temperature resistance and noise reduction in materials remains a challenge.

Hi everyone,

Can anyone suggest a raw material that has the properties similar to steel and produce less noise when meshing with other part. I thought of polymers like Cast nylon, HDPE etc, but the issue is, it has to withstand a temp of around 200°C, during working condition.

Thanks,
r.murali

Depends what you mean by properties similar to steel, as polymers are in no way similar to steel. Especially Nylon, the very best Nylon I've seen has a Moly filled that has about 0.25- 0.3 the tensile strength of mild steel.

What application is this for? Why do yo want 'less noise'? What is causing the noise?

I assume this is a gear as you use the word mesh. If it's gears a redesgin of how the teeth engage is more likely to solve noise problems.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
