Pulley inogona kushandiswa yega kana musanganiswa kuendesa simba uye kufamba. Izvi zvakangogadzirwa, zvishandiso zvine simba zvinotsigira mafambiro uye redirect tension. Nenzira iyi, kuburikidza nesimba radzo diki, dzinogonesa kufamba kwezvinhu zvakakura.

 

A Pulley System

tambo

vhiri

an ekisi

Mapulley anoita mabasa senge kusimudza zvinorema uye kufamba nyore. Inoshandisa vhiri netambo kusimudza mitoro inorema. Vanogona kutenderedzwa. Plastic pulleys anowanikwawo pamusika uye ari kushandiswa kubatsira kutakura masumbu madiki nemitoro. Zvichienderana nekushanduka kwegwara uye ukuru hwesimba, vanoiswa mumhando dzakasiyana.

Kushanda Kushandisa Pulleys

Mapulley ainyanya kushandiswa kuita kuti basa rekusimudza zvinhu zvinorema rive nyore. Pulley inogona kushandiswa yega kana yakabatana nemamwe mapulley kutakura midziyo. Zvimwe zvekushandisa kwayo kwakawanda ndezvi:

Mapulley anoshandiswa kusimudza mvura kubva mumatsime.

Multiple pulleys anoshandiswa pakushanda kweelevator uye escalator.

Mapulleys anogara achishandiswa mumafuta derricks uye anogona kushandiswa kuwedzera manera.

Ivo vanowanzoshandiswa mukutumira uye marine application.

Inoshandiswa kuwedzera mechanic mukana kana ichishandiswa kumaindasitiri emidziyo uye inorema muchina.

Pulley system inoshandiswa nevanokwira matombo kufambisa kukwira. Iyo pulley mechanism inobatsira mukwiri kuenda kumusoro ivo vachidhonza tambo vachidzika.

Pulleys anoshandiswa mune yakawanda yezviyero zvekusimudza zvakagadzirirwa kurovedza muviri. Izvo zvinoshandiswa kudzora kona iyo zviremu zvinokwidziridzwa uchichengeta zviremu panzvimbo yakakodzera.
