Nzira yekusarudza Pulley

Pulley mudziyo unobatsira kufambisa kana kusimudza zvinhu zvinorema. Michina iyi iri nyore inoshandiswa mukushandisa kwakasiyana-siyana, kusanganisira kukwira matombo, zvikepe, uye zvivhariso zvegaraji. Vanoitawo kuti nzira yekufambisa zvinhu zvikuru zvive nyore. Iwo chishandiso chakakosha chinogona kukubatsira kufamba kana kusimudza zvinhu zvakakura.

First, it's important to know the size of the pulley's outside diameter. You can do this by placing a ruler on it and measuring across the middle of the pulley. The outside diameter is usually narrower than the overall width of the pulley. However, this measurement is sometimes difficult if the pulley has wide angle flanges. To avoid this problem, you can measure the diameter of the widest part of the , which will help you figure out the correct size of the pulley.

Another important measurement to make when choosing a pulley is the diameter of the cable. For example, if you have a cable that is three times wider than the pulley's diameter, you'll need to use a smaller pulley. A larger D:d ratio means that the cable will be able to withstand more tension when the pulley is lowered.

Huwandu hwemavhiri uye zvishwe zvine pulley inokanganisawo kuti inogona kusimudza sei. Nekuwedzera mamwe mavhiri kune pulley, unogona kuderedza huwandu hwekuedza hunodiwa kusimudza uremu. Semuenzaniso, pulley ine mavhiri maviri ichakwanisa kusimudza uremu mita imwe.

work very similarly to seesaws. They use rope to move a weight. You can pull it with a small force, which will move the weight over a large distance. But unlike seesaws, a pulley moves a larger weight if you exert more force.

Nheyo yakakosha kuseri kwechidzitiro ndechekuti tambo inomonererwa nevhiri. Kana tambo yadhonzwa, pulley iyi inotenderera, ichikubvumira kusimudza chinhu chinorema. Nemhaka yokuti huremu hwetambo hunotamiswa kuburikidza nevhiri, simba rekusimudza rinodzorerwa shure, izvo zvinoderedza simba rinodiwa kusimudza uremu humwe chete.

Mapulley anoshandiswa muzvishandiso zvakawanda, kubva pakusimudza zvinhu zvinorema kusvika pakusimudza mireza. Anoshandiswawo mutambo dzembatya uye zvekudyisa shiri. Kunyangwe ma crane nema bulldozer anoshandisa masisitimu aya kufamba nekusimudza zvinhu zvinorema. Mukuwedzera, ivo vanoshandiswa muinjini uye zvikepe zvezvikepe.

Pulley mudziyo wemuchina une vhiri rine mikoto yekubata tambo. Vanobatsira kufambisa simba pakati peshaft inotenderera neaxle. Kazhinji, mapulleys anoshandiswa mumaseti kuderedza huwandu hwesimba hunodiwa kufambisa mutoro. Iyo sisitimu yakagadzirirwa kutungamirazve simba kuitira kuti iwedzere kushanda zvakanaka.

Pulley inogona kugadzirwa kubva kune chero emhando dzakasiyana. A fixed pulley ndiyo yakareruka mhando. Simba rinoshandiswa paakisi yepulley yakaenzana nehuwandu hwemakakatanwa pamutsetse wega wega uchisiya. Imwe mhando ipulley inofambiswa, iyo inosanganisira mavhiri ari kufamba.

Kana iwe uine chero chikumbiro, ndapota zadza fomu iri uye isu tinokupindura mukati maawa makumi maviri nemana.
