Question

Using Problem 1, Please prove Number 2 and 3, the answers are already given M and B. please only solve for 2 and 3. Thank you

1. The shaft rotating at 550 rpm carries a spur gear B having 96 teeth with a diametral pitch of 6
and a V-belt sheave with pitch diameter of 10 in. The teeth are of the 20°, full-depth, involute
form. The gear receives 30 hp from a pinion directly above it. Compute the torque delivered
to the shaft and the tangential and radial forces exerted on the shaft by the gear.
TB = 3437.75 in-lb, W₁ = 429.72 lb, W, = 156.4 lb
(a) Pictorial view of assembly
Gear Q
00-10.00-6.00
- Gear B
-V-belt sheave
Section B-B
Section A-A
(b) Detailed views of assembly and its components
2. Problem 1 - determine the maximum moment of the assembly. Hint: Obtain the moments for
vertical and horizontal planes, then compute for the resultant moments.
M = Mc = 6187.86 in-lb.
3. Problem 1 - If one of the bearings is located at the left of C whose bearing seat is made with
small fillet (K₁ = 2.5) and the shaft material is AISI B1113 (k) cold finished, determine the shaft
diameter. Use a size factor of 0.8 and reliability of 99%. Design factor N is 3.
D = 3.0 in.
