    Gearbox shaft material

    Thanks for your replies. I have repaired this shaft with a welding process from eutectic 680S rods and so far so good, done around 10 races wth it and so far so good. Thanks again

    Gearbox shaft material

    I am looking at doing a repair on a automotive gearbox output shaft. It is common practice within the sport to shorten the output shafts on this particular gearbox by cutting and welding the output shaft on the gearbox. I have a shaft to repair which has broken at the weld, This weld has been...

    Water brake dyno coupling

    Can you elaborate on the "this worries me" please After discussions with the manufacturers these items I am looking at can also be run with water for mining applications, And that is the reason I am posting a question here to try and find out why this cannot be used and what the fundemental...

    4-20ma to PC rs232 com port

    I think I will go down the route of a plc. I have a Seimens S5 PLC which I can aquire a Scada package for , Then I would have a few analouge inputs and outputs available and the system would be expandable. I can then use the graphics editing software to create my own graphics for displaying any...

    Water brake dyno coupling

    Your description is exactly what I am in the process of making at the moment, But how can you control the level of water within the brake/pump? By controlling the water flow on the output side/bottom of the pump? or controlling the pressure in? or controlling the flow in?. If the water flow was...

    4-20ma to PC rs232 com port

    Well done ,This is the type of unit I am looking for . May require 3-4 inputs and one output but should be on the right track now. Have you any experience with displaying these signals graphically on the PC eg through a scada type package?

    Water brake dyno coupling

    Its surely quite hard to control the amount of liquid that is in the coupling when it is rotating ? Any idea how they do it in a proper water brake dyno?

    4-20ma to PC rs232 com port

    I am looking for a way to read and manipulate some 4-20ma signals from my PC. ( Basically I am building a Engine Dyno and looking for a way to read and trend the signals from it). I presume there is a way to connect 4-20ma signals and convert them to RS232 which I can then analyse through my PC...

    Water brake dyno coupling

    Sorry should have made myself a bit clearer. What I am looking at is a fluid coupling which would normally be placed between a motor and a gearbox to reduce the strain on a gearbox during motor DOL startup.these are normally filled with oil and sealed with a solder cap which will blow if the...

    Water brake dyno coupling

    Just looking for some advie on an engine dyno I am trying to make. looking into alternative load devices, Water brake AC motor/invertor. Can anybody offer any advice on sourcing a water brake capable of around 170 HP ? Also can anybody offer some advice on the use of a fluid coupling converted...
