Hello,
I need to design an internal gear pump (the type with crescent) and I am looking for information regarding properties of different tooth profile (involute, cycloidal, truninger) and their effects on performance and costs.
Any suggestion will be appreciated.

Hi everyone,
I am dealing with fuel lines for racing application and I often find reference to "dash 4" or "dash 6" fittings; I cannot find any literature about this kind of threaded fitting series; I need some table or chart with dimensions and explanation.
Can anyone help?
It actually does not depends on the size of the system but only on fuel bulk modulus and fuel thermal expansion coefficient i.e. Dp/DV=B (bulk modulus) DV/DT=Ct (thermal expansion coefficient) therefore Dp=B*Ct*DT
You can simply calculate the Dp knowing the two parameters B and Ct
I am about to design a centrifugal pump and I wonder if there is available some freeware code to get some rough impeller sizing before buying a commercial code.
Any hints?
What are the best commercial codes for the purpose?
I need information on gasoline vapour pressure at different temperature, in particular in the 20°C to 80°C range.
I only find data at 100°F and that is not enough for my calculation purposes.
Any suggestion where I can find detailed abacus?
Hello all,
I am currently developing a solenoid actuator which has to fit onto a vessel; Vessel is about 1 liter volume and is filled with air/nitrogen at max 400 bar pressure. Maximum temperature is about 100°C. The fitting between actuator and vessel is about 14-18 mm diameter. Obviously the...
I am using a sheet of rubber to arrange diaphragms. The material is in sheets 0,7 mm thick and it is made of NBR with PA66 reinforcement cloth inside.
I would like to have suggestions about the tests which I should implement in order to ensure the stability and quality of the material as...
Hello guys,
Magneti Marelli has a Motorsport department which is extremely flexible and experienced in term of custom applications. They have or they can arrange for sure what you are looking for.
You can visit the homepage www.magnetimarelli.com and then enter motorsport section. I think to...
My application consists of an actuator where the moving element travels a relatively small distance of less then 0,3 mm.
The needing is to dampen the shock oscillation when the moving elements touches the stopper.
Actually I need some device which absorbs the kinetic energy.
I cannot implement...
Dear all, thank you for your help.
I would like to add some more info.
The application is quasi-static, i.e. the spring displacement is in the order of 0,1 mm therefore there is no friction at all with the plates. The spring is retained by two Ergal plates guided by inside diameter. Spring...
In an automotive application we have a spring made of OTEVA 70 (55SiCr6); the spring is clamped between two Ergal plates. During its life the component is subject to pressurized air up to 4 bar; there could be moisture in the air.
On a 30% basis we find that the spring terminals (were the spring...
