Bhandi nemotokari: huru unhu

The mashandiro ayo anoita nokupfuuridzirwa majana achishandisa bhandi akatasva maviri miseve (pulleys) uye inopa kusanduka kubatana pakati pavo, rinonzi "bhandi hutachiwana". Izvi pezvakaitwa kuitika nokuda panowanikwa kukweshera mauto pakati pulleys uye bhandi ubvise akatambanudza therebetween. Izvi mhando kwemashoko ari kutyaira simba ndiyo imwe mhando mukuru traction simba.

Maererano mhando patepi kushandiswa, bhandi nemotokari anogona kuitwa tichibatsirwa rakatenderera, flat, rectangular giya kana V-bhandi. Zvinhu zviri bhandi ubvise ingangoumbwa, vano- siyana: matehwe, donje jira, rubberized jira , etc.

Nheyo yokuvhiyiwa sezvinotevera: pane mbiri miseve uye nebhanire rwakatambanudzwa pakati pavo. Chisimudziso, nako zvitange kwechirwere, yainzi nemotokari mugodhi, uye imwe chinouya kudhonza, nhapwa. Kuti chikamu tepi iyo runotungamirirwa kusvika nemotokari chisimudziso, ane simba mwero kusungika pane kuenda nemhepo chisimudziso. Somugumisiro, mashoko giya nhamba bhanhire kupfuudzwa - musiyano pakati mwero tensioning wemigove vaviri bhandi. Nokuda ichi nechiyero, zvinokwanisika kuti kuona traction coefficient yacho nemotokari mashandiro.

Zvisinei, pane dzinoverengeka mamiriro ayo. Somuenzaniso, kwakakura bhanhire makakatanwa anofanira kugara aine mukati akafanorongerwa chikuva, kubva kwazvo kukosha ichi angaguma breakage pamusoro bhandi bhandi uye zvakanyanyisa yakaderera makakatanwa, kusiyana, kwaizounza sagging pamusoro bhandi slippage kunogona kuitika. Huru basa anoitwa bhandi nemotokari, aida kuchinja richibatanidza miseve maviri actuator pasina vanachandagwinyira majoini. Panguva dzose nguva kuti kuparadzirwa zvakafanana zvikuru simba.

Kana pakati pulleys daro zvakakwana guru, bhandi nemotokari zvinogona pasi zvaikosha kupfuura kwakavharwa nenyama deformation. Izvi zvinosanganisira bhandi makakatanwa uye, sezvo zvakaguma kwayo sagging. Naizvozvo, mumamiriro ezvinhu akadaro, bhandi zvinogona kuitwa zvakawanda zvinoti, izvo (nokuda kwavo duku kukura) vachaona zvishoma makakatanwa.

V-bhandi yedzimudzangara kunyatsoshanda kunotsanangurwa sezvinotevera. Zvakafanira simba akagamuchira panguva goho yakakamurwa nesimba iro chasvika actuator, uye kunoguma nhamba kane 100%. Bhandi kutapukirwa inogona inozivikanwa se Nokurasikirwa kukosha, iro simba nemotokari nomubato kuti akadzingwa zvakananga kunoenderana.

Belting ane zvinotevera zvazvakanakira: yakaderera cost, pasi kusvibiswa ruzha, kumeso, kushaya lubrication, nyore naro uye nevamwe. Payakaipira - guru kukura, zvingangoita slippage, ari fragility uye vakaderera kubereka vanokwanisa.

Performance bhandi kutapukirwa kunowedzera kana kudzivirira kubata kutsvedza. parameter Izvi zvinoenderana rekona uye ukuru wrap yacho bhandi makakatanwa.

The angled pamusoro wrap - center angled iyo subtends ane chinhu chakakombama akaumba kubatana pfungwa pakati bhandi uye chisimudziso mukati.
