My regards to all
I am current doing my thesis for my masters. I have completed my work, but i seemed to have taken one thing for granted.
lets assume there is a Single Row, Deep Groove Ball Bearing.
Here what i want to know is CAN the outer ring and inner ring move at two different constant rotations, in the same direction.
I know it might be quiet simple a question, but i am primarily concerned with the rate at which the balls will wear.
the specifications of the scenario are as follows
please refer this picture for nomenclature - http://www.reliance.com/mtr/images/befig4.gif
let us assume the outer ring to rotate at = x rads/sec
then inner ring is expected to rotate at = 2x rads/sec
[the rpm is not supposed to be very high, on the order or max 60 rpm, so its very less]
I really want to know if under these conditions how long would the ball last - I do agree there should be a great increase in wear as apposed to one of the rings being static, but will it excessive wear so as to make the device impractical.
SUMMARY - Can the outer and inner rings of a single Row, Deep Groove Ball Bearing rotate at TWO DIFFERENT CONSTANT speeds IN the SAME direction. If so, how bad is the increase in wear of the balls.
Thanks to all in advance
