Imifanekiso ebonisa apha ngasentla ngumzekelo wenkqubo yokuhambisa ejikelezayo enamaleko amathathu. Iingubo zendlela yokuthwala kunye nendlela yokubuya zenziwe ngezinto ze-HDPE. Ububanzi bebhanti bubonke yi-500mm kwaye yamkele i-HS-300B-HD kunye ne-sprockets enamazinyo ayi-8. Ubude becandelo elithwele ngokuthe tye kwi-drive kunye ne-idler end yi-1 mitha ngokulandelanayo. I-radius yayo yangaphakathi yokujika yi-1.5M, kwaye izinto zokuthutha ziibhokisi zeposi kwi-50Kg/M2. Isantya sokusebenza somthumeli si-25M / min, sithambekele ekuphakameni kwe-4M kwaye sisebenze kwindawo eyomileyo. Ubalo olunxulumeneyo lulandelayo.

  1. Ukubalwa kweyunithi yoxinzelelo lulonke - TWS

IFOMU :

TW = TB × FA

TWS = 958.7 × 1.6 = 1533.9 ( Kg / M )

IFOMU :

TB = [ 2 × R0 × M + ( L1 + L2 ) ] ( WP + 2 WB ) × FBW + ( WP × H )

I-TB = [ 2 × 3.1416 × 2 × 3 + ( 1 + 1 )] ( 50 + 2 × 5.9 ) × 0.35 + ( 50 × 2 )
I-TB = 958.7 ( Kg / M )
  1. Ukubalwa kweyunithi yoxinzelelo oluvumelekileyo - TA

IFOMU :

TA = BS × FS × FT
TA = 2118 × 1.0 × 0.95 = 2012 ( Kg / M )
Ngenxa yexabiso i-TA inkulu kune-TW; ngoko ke, ukwamkela Series 300B-HD ibhanti lukhetho olukhuselekileyo nolufanelekileyo.
  1. Nceda ubhekisele kwisithuba seSprocket se-HS-300 kwiSahluko se-Drive Sprockets; isithuba esikhulu se-sprocket simalunga ne-145mm.
  2. I-Deflection ratio ye-drive shaft - i-DS

IFOMU :

SL = ( TWS + SW ) × BW
SL = ( 1533.9 + 11.48 ) × 0.5 = 772.7 ( Kg )

IFOMU :

DS = 5 × 10-4 × [ ( SL × SB3 ) / ( E × I )]
DS = 5 × 10-4 × [ ( 772.7 × 6003 ) / ( 19700 × 174817 )] = 0.024 ( mm)
  1. Ukuba isiphumo sobalo sincinci kunexabiso elisemgangathweni elidweliswe kwiTheyibhile yokuPhambuka; ukwamkela iibheringi ezimbini zebhola kwanele kwinkqubo.
  2. Ukubalwa kwe-shaft torque - TS

IFOMU :

TS = TWS × BW × R
TS = 1533.9 × 0.5 × 92.5 = 70942.8 (kg - mm)
Xa kuthelekiswa ne-Maximum Torque Factor kwiyunithi ye-Shaft Selection, siyazi ukuba ukusetyenziswa kwe-38mm × 38mm square shaft kukhuselekile kwaye kukhethwe ngokufanelekileyo.
  1. Ukubalwa kwamandla ehashe - HP

IFOMU :

HP = 2.2 × 10-4 × [ ( TS × V ) / R ]
I-HP = 2.2 × 10-4 × [ ( 70942.8 × 4 ) / 60 = 1.04 ( HP )
Ngokubanzi, amandla omatshini we-center drive conveyor anokulahlekelwa malunga ne-40% ngexesha lokusebenza.
MHP = [ 1.04 / ( 100 - 40 )] × 100 = 1.73 ( HP )
Ukwamkela i-2HP drive motor lukhetho olufanelekileyo.
