HONG'S BELT

A. Flat belt design points

1. K1% after running (suitable for drive belt)

K1% means the belt running on the machine, when the relaxation tend to the steady number.

K%(after running)(k% a.r.i)

2. Angle

a. when the F1 change to F2, the belt angle a1 changes to a2.

b. when the F2 change to F1, the belt angle a2 changes to a1.

c. the belt angle changes in the range of BG, the power transport apears in the range of BA.when the transport power bigger the BG will be bigger.

3. Explanation of "slip"

a. when the conveyor power bigger, the BG will be bigger.

b. if the BG replace for BA, it will slip.

c. if the F1 reaches to biggest, the F2 least, the system will be in the heavy transport power: Eytelwein F1/F2 ≦ e ^µβ

4. Anlistatig method

a. conductive surfaces
b. conductive layers-carbon coating
c. conductive thread inside the cloth

5. Drive belt design points

Pulley diameter[mm]	Height of crown h[mm]
40 , 50 , 63 , 71 , 80 , 90 , 100 , 112 125 , 140 160 , 180 200 , 224 150 , 280 , 315 , 335 400 , 450 , 500 560 , 630 , 710	0.3 0.4 0.5 0.6 0.8 1.0 1.2

B. conveyor belt design points

1. Conveyer belt and roller width cooperating suggestion

Expressions :
bo≤100mm b=b。+20mm
bo>100mm b=(1.08·b。)+12mm

2. Driver roller suggested to use cylindric-conical roller

Expressions :
bc=b。/2 for b。≤2000mm
bc=b。-1000 for b。>2000mm

Diameter d[mm]	≤ 50	100	150	200	250	300	350	400	450	500	> 500
Gradient h[mm]	0.25	0.35	0.45	0.55	0.65	0.75	0.85	0.95	1.05	1.15	1.15

The gradient too high will lead : The belt can't touch the both side of coniacl, the leading can't be well. The transverse power too stronge will make the belt pucker.

3. Belt leading methods

a. stronge shelf
b. roller and pulley must be set upright to the belt running direction.
c. more than one drived roller made cylindric-conical (axes distance more than 4-5mt.)
d. at the long distance convey or inverted drive status, the driver and passive pulley must made cylindric-conica
e. keeping the puller, roller, board clean any time.

4. The rollers designing

a. made cylindric as a rule

b. more than one drived roller made cylindric-conical (axes distance more than 4-5mt.)

5. Conveyer belt pattern

a. Static K1% Outlying of belt count, easy for measure.

b. After belt loosing K1% Usd for exact measure belt.
