Calculation of unit total tension - TWS
| FORMULA: | TW = TB × FA |
|
| TWS = 958.7 × 1.6 = 1533.9 Kg / M |
|
| |
| FORMULA: | TB = [ 2 × R0 × M + ( L1 + L2 ) ] ( WP + 2 WB ) × FBW + ( WP × H ) |
|
| TB = 2 × 3.1416 × 2 × 3 + ( 1 + 1 ) ] ( 50 + 2 × 5.9 ) × 0.35 + ( 50 × 2 ) |
| TB = 958.7 (Kg / M) |
- Kev suav ntawm chav tso cai nruj - TA
| FORMULA: | TA = BS × FS × FT |
| TA = 2118 × 1.0 × 0.95 = 2012 (Kg / M) | |
| Vim tus nqi TA loj dua TW;yog li ntawd, txais yuav Series 300B-HD siv yog ib qho kev nyab xeeb thiab xaiv kom raug. |
- Thov xa mus rau Sprocket qhov sib nrug ntawm HS-300 hauv Tsav Sprockets Tshooj;qhov siab tshaj plaws sprocket nrug yog kwv yees li 145mm.
- Deflection ratio ntawm tsav ncej - DS
| FORMULA: | SL = (TWS + SW) × BW |
| Luas = (1533.9 + 11.48) × 0.5 = 772.7 (Kg) | |
| FORMULA: | DS = 5 × 10-4 × [ ( SL × SB3 ) / ( E × I ) ] |
| DS = 5 × 10-4 × [ ( 772.7 × 6003 ) / ( 19700 × 174817 ) ] = 0.024 (mm) |
- Yog tias qhov txiaj ntsig ntawm kev suav me me dua tus qauv tus nqi uas tau teev tseg hauv Deflection Table;txais yuav ob lub pob bearings yog txaus rau lub kaw lus.
- Kev suav ntawm ncej torque - TS
| FORMULA: | TS = TWS × BW × R |
| TS = 1533.9 × 0.5 × 92.5 = 70942.8 (kg - mm) | |
| Nyob rau hauv kev sib piv nrog rau qhov Maximum Torque Factor hauv Shaft Selection unit, peb paub tias kev siv 38mm × 38mm square ncej muaj kev nyab xeeb thiab xaiv kom zoo. |
- Kev suav ntawm horsepower - HP
| FORMULA: | HP = 2.2 × 10-4 × [ ( TS × V ) / R ] |
| HP = 2.2 × 10-4 × [ ( 70942.8 × 4 ) / 60 = 1.04 (HP) | |
| Feem ntau, lub zog txhua yam ntawm qhov chaw tsav tsheb yuav poob li 40% thaum lub sijhawm ua haujlwm. | |
| MHP = [ 1.04 / ( 100 - 40 ) ] × 100 = 1.73 (HP) | |
| Txais yuav 2HP tsav lub cev muaj zog yog qhov kev xaiv zoo. |
