@ Precision gears & sprocket ratio ...Geskovski
Dimitrije eng geskovski@yahoo.com
INFO: Program calculate four variable teeth of gear or
sprocket for precision gears ratio (technology speed )(m/min),(fp/s) or number
of revolution (rpm), used by foil traction e.t.c
Numeric example(inch value)
Input revolutions per minute of drive reducing n(r.p.m.)=
125
Input 1 for metric , -1 for inch measuring m=
-1
Input roll diameter d(inch)= 9.75
Input necessary track speed v(fps)= 0.3
necessary ratio r= 17.726
Input maximalrelative speed tolerance, Rv(%)=
.0005
Maximal tolerance of gear ratio, qr=
8.863E-05
Input the tolerance of ratio, q= 0.00008
Input the lowest limit of the teeth numbers C and
D{usually 12}, x2= 13
Input the lowest limit of the teeth numbers B(usually 13),
x1= 13
Input the highest limit of the teeth numbers B(us. 50 to
130), y2= 115
Input the highest limit of the teeth numbers C and D (us.
50 to 100), y3= 101
Input the increment (usually 1), s1= 1
Input the increment (usually 1 or 2), s2=
1
Type f for one existing (gear A) and three variable teeth
number,ANY for four variable teeth numbers ...any
Input starting value from teeth number A(usually 70 to
130), x0= 127
Input value of diapason for the teeth numbers A(us. 3 to
5), di= 4
gear ratio :
B(A) A
(B)
C(D) D(C)
17.72595

17.72595 = 128 * 95 / (49 * 14)
calculated speed v= 0.3000009 (fps)
speed tolerance Dv= -8.642673E - 07 (fps)
relative speed tolerance Rv(%)= -2.880891E -
04
