View Full Version : centrifugal Gears?

Why dont the manufacturers use double helical gears? Do some of them? and does anyone retrofit to them? Is the thrust from a single helix gear serving a purpose?
i'm guessing it serves no purpose and the double helixcal gear eigther dos'nt transmit the power in the same size as the single, like it needs to be bigger for the same torque, or its just too exspencive.

The Carrier "Dyna-Poise" transmission is a beutiful use of double-helical or "Herringbone" style gearbox.
It does in fact increase/decrease speed without transferring any thrust from either the prime over or the load itself.
The Single helical or Seerbathe cut gears can on the other hand be cut at a given angle so as to equal and therefore neutralize any given thrust load.
As the impeller therefore is trying to go towards Mecca, the angle cut on the gears are designed to pull impeller back to its home base....
Soooo.... Pick your favorite......Just do not bring back the Planetary speed increaser that was used on the old Worthington Sentry chillers....What a nightmare it was..

I agree, the planatary gears were a nightmare. Expensive little buggers too.

Man.. "Dyna Poise"
That's even better'n "Torqueflite"
