Linear Motion Guide ndi gawo lotumizira pamakina lomwe limatha kuwongolera zida zamakina kuti ziziyenda bwino komanso bwino panjira yokhazikika. Ndilo gawo lofunikira kwambiri pakukwaniritsa{1}}kuwongolera kolondola kwamayendedwe pamakina amakono. Imachepetsa kukangana koyenda, imakweza kuchuluka kwa katundu, ndikuwonetsetsa kuwongoka ndi malo olondola amayendedwe oyenda mwa kukhathamiritsa njira zolumikizirana ndi kapangidwe kake. Linear Motion Guide imagwiritsidwa ntchito kwambiri m'magawo ofunikira a zida zolondola monga zida zodzipangira okha, zida zamakina olondola, maloboti, ndi zida zamankhwala.
Linear Motion Guide ndi makina olondola kwambiri-oyenda kwambiri,{1}}liwiro kwambiri, ndiponso amayenda pang'onopang'ono podutsa m'makina okhotakhota, omwe amagwiritsidwa ntchito kuwongolera{2}}kuthamanga kwambiri, kocheperako kwa zinthu zomwe zili m'njira. Itha kulowa m'malo mwa maupangiri achikhalidwe, kukonza bwino kuyenda, kusasunthika, komanso kulondola kwa malo, ndipo imagwiritsidwa ntchito kwambiri pamakina amakono ndi makina olondola. Kuchita kwake kumakhudza mwachindunji kulondola kwa malo, moyo wautali, komanso mphamvu ya zida.
Kapangidwe kakalozera kamayendedwe kamene kamakhala ndi magawo anayi:
1) .Njanji: Chigawo chachitali, cholimba chokhazikika pazida zazida, zokhala ndi mizere yolondola kapena njanji zomangika pamwamba pake kuti zipereke njira yolozera kuyenda.
2) .Slider / Carriage: Chigawo chosunthika cholumikizidwa ku gawo losuntha, lomwe lili ndi zinthu zogudubuza kapena zotsetsereka mkati ndikuyenda motsatira njanji yowongolera.
3) .Chinthu chogudubuzika/chinthu chotsetsereka: Chigawo chotumizira mphamvu chomwe chili pakati pa njanji yowongolera ndi slider. Nthawi zambiri njanji zogudubuza zimakhala zomangira mipira, zodzigudubuza, kapena zodumphadumpha, zomwe zimachepetsa kulimba chifukwa cha kukangana;Njanji zotsetsereka zimapangidwa ndi zinthu zosagwira ntchito (monga polytetrafluoroethylene, alloys) kuti azitha kutsetsereka.
4) . Dongosolo lozungulira (losiyana ndi mtundu wogubuduza): Pamene chinthu chozungulira chimayenda ndi slider mpaka kumapeto, chimabwereranso kumalo oyambira kupyolera mu njira yozungulira (monga chipangizo chosinthira kapena chingwe), kukwaniritsa "stroko yopanda malire" kuyenda ndikuonetsetsa kuti kufalikira kosalekeza komanso kosasunthika.
Panthawi yogwira ntchito, slide imayendetsedwa kuti isunthire motsatira njanji yowongolera, ndipo katundu wazomwe amasuntha amatumizidwa ku gulu la njanji yowongolera kudzera muzinthu zogubuduza kapena zigawo zotsetsereka. Panthawi imodzimodziyo, kuwongoka kwa njira yoyendayenda kumatsimikiziridwa ndi mawonekedwe olondola a msewu wothamanga (monga Gothic arc, circular arc), ndipo kukhwima ndi kulondola kumakonzedwanso kupyolera mu mapangidwe a pretensioning (kukonza kusiyana pakati pa slider ndi njanji yowongolera).
Kutengera ndi mikangano komanso kusiyana kwamapangidwe, kalozera woyenda atha kugawidwa m'magulu akulu awa:

Sitima yapamtunda yotsetsereka |
Palibe zinthu zogubuduza, zomwe zimafalitsidwa kudzera pakulumikizana kotsetsereka pakati pa slider ndi njanji yowongolera, mawonekedwe osavuta, otsika mtengo, koma kukangana kwakukulu. |
Katundu wopepuka wochepera-zida zothamanga, makina otumizira osavuta |

Sitima yapamtunda yoyandama/maglev |
Kugwiritsa ntchito mpweya kapena mphamvu ya maginito kuti musadutse-kusuntha, kukangana kumafika pa ziro, osatha, oyenera kuwonetsetsa kulondola kwambiri |

Liniya zoyenda kalozera ndi "ogwirizana" wa zochita zokha mafakitale, ndi ntchito yake walowa pafupifupi pafupifupi zochitika zonse zimene zimafuna yolondola liniya zoyenda: kuchokera kayendedwe zopalira zida CNC makina zida, kutambasuka ndi kubweza manja loboti, kuti ❖ kuyanika yunifolomu ya lithiamu batire ❖ kuyanika makina ndi sikani mayendedwe bedi la zida CT, onse amadalira pa izo kukwaniritsa molondola.
Ndi kupita patsogolo kwa Industry 4.0 ndi kupanga mwanzeru, maupangiri oyenda akukula kupita ku nzeru (zomangidwa-mu masensa kuti aziyang'anira kavalidwe, kutentha, ndi zina), kulondola kwambiri (mawonekedwe a nanometer), kuphatikiza (mapangidwe ophatikizika okhala ndi ma mota ndi ma encoder), komanso kusintha kwapadera kwa chilengedwe (kukana kwa dzimbiri), kutulutsa mpweya wosasunthika, kutulutsa fumbi lochepa, m'magawo apamwamba-opanga ndi olondola aukadaulo.
Linear motion guide ndi mpira screw ndi zigawo zofunika kwambiri kuti mukwaniritse kuwongolera kwamakina olondola, koma ali ndi kusiyana kofunikira pakugwira ntchito, mfundo, ndi momwe amagwiritsira ntchito. Kusiyana kwakukulu kuli motere:

Ntchito zosiyanasiyana pachimake |
Ntchito yake yayikulu ndikuwongolera njira yoyendetsera, kuonetsetsa kuti zigawozo zikuyenda bwino pamzere wowongoka wokhazikika pomwe zikunyamula katundu (kuphatikiza ma radial, axial forces, ndi mphindi). Sichimapereka mwachindunji mphamvu yoyendetsera galimoto, koma imagwira ntchito ngati "njira yotsogolera" yoyenda. |
Ntchito yake yayikulu ndikukwaniritsa kutembenuka koyenda ndi kutulutsa mphamvu, kutembenuza kusuntha kwa mota kuti ikhale yozungulira pomwe ikutumiza mphamvu ndi kulondola kwamayendedwe (monga kuwongolera mtunda woyenda). Ndilo gawo la "power transmission + positioning". |

Mapangidwe osiyanasiyana ndi mfundo zogwirira ntchito |
wopangidwa ndi njanji yowongolera, slider, chinthu chogudubuza (mpira/rola) ndi makina ozungulira. Chotsetsereka chimayenda motsatira njanji yolondolera kupyola muzinthu zogudubuza, kudalira mayendedwe olondola opangidwa ndi makina kuti awongoke. Imakulitsa kukhazikika komanso kulondola mwa kukhwimitsa ndi kuwongolera zololeza. |
wopangidwa ndi screw shaft, nati, mpira, ndi makina ozungulira. Pamene injini ikuyendetsa wononga kuti izungulire, mpirawo umayenda pakati pa nsonga ya ulusi ndi nati, ndikuyendetsa natiyo kuti ikhale yozungulira. Mtunda woyenda umayendetsedwa ndi ulusi wotsogolera (ochepa kutsogolera, kumtunda kulondola). |

Kuchita kumayang'ana mbali zosiyanasiyana |
imayang'ana pa kulondola kowongolera (kuwongoka, kufanana), katundu-kuchulukira (makamaka katundu wa radial ndi mphindi yakugudubuzika), ndi kuyenda mosalala (kugunda kochepa, osakwawa). Mwachitsanzo, njanji zamakina olemera-ziyenera kupirira matani angapo amphamvu poonetsetsa kuti zida zayenda mowongoka. |
imayang'ana pa kulondola kwa kufalitsa (kulakwitsa kwa malo, cholakwika chobwerezabwereza), kuyendetsa bwino (mpaka 90% kapena kupitilira apo, kumtunda kwambiri kuposa 30% ya zomangira zotsetsereka), ndi kulumikizana koyenda. Mwachitsanzo, mbali ya chakudya ya chida cha makina a CNC imayendetsa bwino mtunda woyenda wa chida kudzera pa screw screw, ndipo cholakwikacho chiyenera kulamulidwa pamlingo wa micrometer. |

Zochitika zosiyanasiyana zogwiritsira ntchito |
Ikagwiritsidwa ntchito yokha, siyingayendetsedwe ndipo imayenera kulumikizidwa ndi zida zoyendetsera monga zomangira za mpira ndi ma injini amzere. Ntchito zofananira: chitsogozo cha omwe ali ndi zida zamakina, mayendedwe owonera ma telescopic a mikono ya loboti, chitsogozo cha tebulo la slide pazida zodzichitira, ndi zina. |
Monga poyambira, iyenera kugwiritsidwa ntchito ndi njanji yowongolera (kupanda kutero sikungatsimikizire kuyenda kwa mzere). Ntchito zofananira: makina odyetsera zida zamakina olondola, makina omangira makina omangira jakisoni, ma driver a nozzle a osindikiza a 3D, ndi zina zambiri. |
Zomangira za mpira zimayang'anira "kutumiza mphamvu ndi kuwongolera mtunda", pomwe maupangiri amzere ali ndi udindo wa "kuwongolera njira ndikuthandizira katundu". Pazida zolondola, nthawi zambiri zimagwiritsidwa ntchito mophatikizana (monga ma ax a X/Y a zida zamakina a CNC) kuti azitha kuyendetsa bwino kwambiri{1}}.
