1 / 2
Calculations
Givens
T= 500
N.mD=20
cma =10
cmW=900
rpm
Where:
A: Center of the left bearing
B: Center of the shaft (Also center of the gear)
C: shoulder at the left of the gear
D: Groove at the right of the gear
E: shoulder at the left of the right bearing
Force Analysis
∑M=0
F*cos(20) * D/2 = T 🡺 F = 500
(0.1)∗cos(20) =5320.89 N = 5.32 KN
FT = 5000 N = 5 KN
Fr = 1819.85 N = 1.8 KN
Reactions
In Y-Direction
Ray = Rby = Fr / 2 = 0.9 KNPowered by TCPDF (www.tcpdf.org)
