Harnessing rear wheel power

Harnessing rear wheel power

Harnessing rear wheel power

(OP)
Greetings  .  Pitcher a motorcycle with its rear wheel sitting in a  2 roller  dyno cradle.  The  object is to  bevel gear  the out put off one roller 90 degrees. Similarly  I want to  try to match  the  engine  rpm on this  shaft.( at least 3/4's) The  rear wheel to the  dyno  roller is  a speed increase  . However the roller needs to  be  large enough  to  provide  good contact  to  the tire. Figure  4 : 1   So  all the  reduction  cant happen  here . Which  leaves  the  rest of the rpm increase  to be made up in the bevel gears.  And this  is  where  things  start getting  fuzzy .  The  bevel gear out put shaft is  pulling  a axial flow jet pump which in most cases  are  direct  coupled to the motor. Using  the massive rear wheel torque  to  regain  RPM to power the pump is  what I'm after. Any ideas  on how to  track this  down ?

Just  a round about  way to get there  would be  grate.  Anyone ?

RE: Harnessing rear wheel power

You don't really say what you want to do. Are you trying to use your motorcycle to power a pump? Building a test stand? I don't think you are getting any responses because your question is hard to follow.

I  figured it out  ,  4 revs on the  drum roller off of  1 rev  from the wheel will work just  fine.  The  rest is  1 to 1.
 Thanks.
