I have been trying to draw an accurate representation of a spline BS 3550 and have written a program to plot, from a given base circle, the involute between the major diameter and the minor diameter.
However is the spline form a true involute or does the cutter “modify” the involute as it...
We have upgraded to V15 however the QuickPick selection tool is un-usable. It is incredibly slow. Tried adjusting the setting but it is virtually impossible to select a part. Is it possible to revert to V14 or is there a fix for it.
I am interested in the efficiency of large transmissions - 6 x 6 12 tonne off road vehicles and buses /coaches. Form the engine output through to the wheels. Is the efficiency constant with speed or does it reduce at higher speeds?
Also what is the cost of a new transmission?
Thanks in advance
I am looking for a definitive text on heat transfer preferably one that covers the theoretical and the practical particularly for cooling of motor, gear boxes etc. I have tried various University texts however they seem to cover the theory and get you through the exam! I have been recommended:-...
We have a cylindrical shell that requires cooling by around 380 kW it is 380 mm outside dia with a .75 mm fluid film of gearbox oil. The pressure drop across it has to be minimal (i.e. preventing turbulent flow regime) with flow rate around 20 L/min. I have tried calculating it but is the...
