Dhiraivha bhandi tensioner yakakosha kune yakajairika kushanda kwesimba remagetsi, saka chikamu ichi chinofanira kuchinjwa kana paine kusashanda.Asi usati watenga roller itsva, unoda kunzwisisa marudzi ayo aripo, magadzirirwo uye nheyo yekushanda.
Mhando uye dhizaini yedhiraivha bhandi tensioners
Chero dhiraivha bhandi tensioner ine zvikamu zviviri: tensioning mudziyo unogadzira simba rinodiwa, uye roller inoendesa iyi simba kune bhandi.Kune zvakare zvishandiso zvinoshandisa tensioner-damper - hazvipi chete inodiwa bhandi kushushikana, asi zvakare kuderedza kusimba kwekupfeka kwebhanhire uye pulleys emayuniti mune zvenguva pfupi nzira dzekushanda kweiyo magetsi unit.
Iyo tensioner inogona kuva ne-roller imwe kana maviri, zvikamu izvi zvinogadzirwa nenzira yesimbi kana vhiri repurasitiki rine nzvimbo yekushanda yakatsetseka iyo bhanhire rinotenderera.Iyo roller inosungirirwa pane tensioning device kana pane yakakosha bracket kuburikidza ne rolling bearing (bhora kana roller, kazhinji mutsara mumwe chete, asi pane zvigadzirwa zvine mabheji maviri-mutsara).Sezvo mutemo, nzvimbo yekushanda ye roller yakatsetseka, asi pane zvingasarudzwa nemakorori kana zvakakosha protrusions zvinodzivirira bhanhire kuti rirege kutsvedza apo injini iri kushanda.
Iwo ma roller akaiswa akananga patensioning zvishandiso kana pane zvepakati zvikamu nenzira yemabhuraketi eakasiyana magadzirirwo.Zvishandiso zvekumanikidza zvinogona kukamurwa kuita mapoka maviri zvichienderana nenzira yekugadzirisa simba rekumanikidza rebhandi rekutyaira:
● Nekugadzirisa kwemaoko kwechiyero chekunetseka;
● Nekugadzirisa otomatiki kwedhigirii rekushushikana.
Boka rekutanga rinosanganisira nzira dzakareruka mukugadzira, dzinoshandisa eccentric uye slide tensioning zvishandiso.Iyo eccentric tensioner inogadzirwa nenzira ye roller ine offset axis, kana ichitenderedzwa iyo iyo roller inounzwa pedyo kana kure nebhanhire, iyo inopa shanduko musimba rekumanikidza.Slide tensioner inogadzirwa nenzira ye roller yakaiswa pane inofambiswa slide inogona kufamba nepakati pe groove yegwaro (bracket).Kufamba kwe roller pamwe chete negwaro uye kugadzirisa kwayo munzvimbo yakasarudzwa kunoitwa ne screw, giredhi pachayo inoiswa perpendicular kune bhanhire, saka, kana roller inofamba pairi, simba rekumanikidza rinoshanduka.
Zvishandiso zvine manyorero ekugadzirisa mabhanhire ebhanhire pazvinjini zvemazuva ano hazviwanzo kushandiswa, sezvo zvine zvakakosha drawback - kudikanwa kwekushandura kupindira panguva yekutanga kugadzwa kwechikamu ichi uye sezvo bhanhire rinotambanudza.Matsimba akadaro haagone kupa dhigirii inodiwa yekushushikana kwebhandi mukati mehupenyu hwese hwesevhisi, uye kugadziridzwa kwemanyorero hakuwanzo chengetedza mamiriro acho - zvese izvi zvinotungamira mukupfeka kwakanyanya kwezvikamu zvekutyaira.
Naizvozvo, mota dzemazuva ano dzinoshandisa tensioning zvishandiso zvine otomatiki kugadzirisa.Masimba akadaro akakamurwa kuita mapoka matatu zvichienderana nedhizaini uye musimboti wekushanda:
● Kubva pazvitubu zve torsion;
● Kubva pazvitubu zvekumanikidza;
● Nemadhamu.
Midziyo inonyanya kushandiswa yakavakirwa pazvitubu zve torsion - ivo vakanyatso compact uye vanoita mabasa avo nemazvo.Hwaro hwechigadzirwa ihombe-dhayamita yakakomberedzwa chitubu chakaiswa mukapu yecylindrical.Chitubu chine imwe yakanyanyisa coil inogadziriswa mugirazi, uye iyo yakatarisana nekoiri inogara pabhuraketi ine roller, girazi uye bhureki inogona kutenderedzwa pane imwe kona inoganhurwa neinomira.Mukugadzirwa kwechigadzirwa, girazi uye bracket zvinotenderedzwa pane imwe kona uye inogadziriswa munzvimbo iyi nemudziyo wekuchengetedza (cheki).Paunenge uchiisa tensioner pajini, cheki inobviswa uye bhuroketi inotaridzirwa pasi pechiito chechirimo - semugumisiro, roller inozorora kurwisana nebhanhire, ichipa dhigirii inodiwa yekupindira kwayo.Mune ramangwana, chitubu chichachengetedza kukakavara kwakaiswa, kuita kuti kugadzirisa kusingakoshi.
Midziyo yakavakirwa pazvitubu zvekumanikidza inoshandiswa zvishoma, sezvo inotora nzvimbo yakawanda uye isinganyanyi kushanda.Nheyo yemudziyo wekumanikidza ndeye bracket ine roller, iyo ine swivel yekubatanidza ine yakamonyoroka cylindrical spring.Kupera kwechipiri kwechitubu kwakasungirirwa pajini - izvi zvinovimbisa kupindira kwebhanhire rinodiwa.Sezvakaitika kare, simba rekunetsa kwechitubu rinoiswa pafekitari, saka mushure mekuisa chigadzirwa pajini, cheki kana fuse yeimwe dhizaini inobviswa.
Iko kuvandudzwa kwema tensioners ane compression spring chaive chigadziro chine dampers.Iyo tensioner ine dhizaini yakafanana neyakatsanangurwa pamusoro apa, asi chitubu chinotsiviwa nedamper, iyo inosungirirwa kune bracket ine roller uye mota nerubatsiro rweziso.Iyo damper ine compact hydraulic shock absorber uye yakakomberedzwa chitubu, uye iyo yekuvhundutsa inopinza inogona kuwanikwa mukati mechirimo uye kuita serutsigiro rwekupedzisira coil yechirimo.Iyo damper yeiyi dhizaini inopa inodiwa bhandi kupindira, uku ichitsvedzerera kunze kuzununguka kwebhanhire paunenge uchitanga injini uye mune zvenguva pfupi modes.Kuvapo kwe damper kunowedzera hupenyu hwekutyaira kwemayuniti akaiswa uye kunovimbisa kushanda kwayo kwakanyanya.
Mukupedzisa, zvinofanirwa kucherechedzwa kuti iyo yakatsanangurwa dhizaini ine tensioners ane maviri maviri rollers.Muchiitiko ichi, zvishandiso zvine maviri rollers zvinogona kuve neyakajairwa tensioning mudziyo, kana kupatsanura zvishandiso kune yega yega rollers.Kune dzimwe mhinduro dzinovaka, asi dzakagamuchira kugoverwa kushoma, saka hatizodzifunga pano.
Nyaya dzekusarudza, kutsiva uye kugadzirisa kwedhiraivha bhandi tensioner
Iyo tension roller yebhanhire rekutyaira, sebhandi pacharo, ine shongedzo shoma, iyo budiriro inofanirwa kutsiviwa.Mhando dzakasiyana dzetensioners dzine akasiyana sosi - mamwe acho (iyo yakareruka eccentric) anofanirwa kuchinjwa nguva nenguva uye pamwe nekutsiviwa kwebhanhire, uye zvishandiso zvinoenderana nezvitubu uye nemadhamu zvinogona kushanda munenge panguva yese yekushanda kwesimba remagetsi.Iyo nguva uye maitiro ekutsiva tensioning midziyo inoratidzwa nemugadziri weimwe simba remagetsi - izvi zvinongedzo zvinofanirwa kuteedzerwa zvakanyanya, zvikasadaro mhedzisiro yakaipa yemagetsi unit inogoneka, kusanganisira jamming yayo (nekuda kwekupisa nekuda kwekumisa pombi. )
Idzo chete mhando uye mhando dzetensioners dzinokurudzirwa nemugadziri wesimba remagetsi dzinofanirwa kutorwa kuti dzitsive, kunyanya kumota dziri pasi pewaranti."Zvisiri zvekuzvarwa" zvishandiso zvinogona kunge zvisingaenderane mune hunhu ne "yekuzvarwa", saka kuisirwa kwavo kunotungamirira kukuchinja kwesimba rekunetsa kwebhanhire uye kuderera kwemamiriro ekushanda ekutyaira kwemayuniti akaiswa.Nokudaro, kutsiva kwakadaro kunofanira kushandiswa chete mumamiriro ezvinhu akaoma.
Paunenge uchitenga tensioning device, unofanira kutenga zvinhu zvose zvinodiwa pairi (kana zvisingabatanidzwi) - fasteners, mabhuraketi, zvitubu, nezvimwewo. Mune zvimwe zviitiko, haugoni kutora tensioners yose, asi kugadzirisa kits - rollers chete ine yakaiswa. mabhengi, mabhuraketi, madhamu akaunganidzwa nezvitubu, nezvimwe.
Kutsiviwa kwedhiraivha bhandi tensioner kunofanirwa kuitwa zvinoenderana nemirairo yekugadzirisa nekugadzirisa mota.Iri basa rinogona kuitwa zvose nebhanhire rakaiswa uye nebhanhire rakabviswa - zvose zvinoenderana nekugadzirwa kwedhiraivha uye nzvimbo yekumanikidza mudziyo.Pasinei neizvi, kuiswa kwechitubu tensioners kunogara kuchiitwa nenzira imwecheteyo: chigadziro uye bhanhire zvinotanga kuiswa panzvimbo yavo, uye cheki inobviswa - izvi zvinotungamirira pakusunungurwa kwechirimo uye kushushikana kwemhepo. bhandi.Kana nokuda kwechikonzero chipi nechipi kuiswa kwetensioner yakadaro kunoitwa zvisizvo, zvino zvichange zvakaoma kuidzorera zvakare.
Kana iyo tensioning mudziyo yakanyatso kusarudzwa uye yakaiswa painjini, dhiraivha yemayuniti ichaita seyakajairwa, ichivimbisa kushanda kwakavimbika kweiyo yese simba unit.
