Hello students, in this question we have a sperm neon gear which is given.
00:06
So, given that the diameter of the gear is equal to 120 millimeter, power transmitted is 5 kilowatts, pressure angle alpha is equal to 20 degrees and then rotational speed np is equal to 200 rpm and the velocity ratio vr is equal to 2 .50.
00:30
To find out the required parameters, first we need to calculate the diameter and the rotational speed.
00:37
The velocity ratio vr is defined as the ratio of the driven gear to the neon gear rotational speed.
00:50
So, that is given by the equation nd by np that is rotational factor.
00:57
So, with that we can find out the nd which is the rotational speed we can find out.
01:04
So, nd will be equal to vr times np.
01:08
So, that will be equal to vr is 2 .50 times np is 200...
