Zodzigudubuza za Planetary: Korona wa Kutumiza Kwapamwamba Kwambiri

Planetary Roller Screw(mtundu wokhazikika) ndi njira yotumizira yomwe imaphatikiza kusuntha kwa helical ndikuyenda kwa mapulaneti kuti asinthe kusuntha kwa wononga kukhalakusuntha kwa mzerecha nati. Planetary Roller Screws ali ndi mawonekedwe amphamvu yonyamula katundu, kukhazikika kwakukulu, kulondola kwambiri, kukana kuvala, kukana kugwedezeka ndi moyo wautali, ndi zina zambiri, zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale ndi chitetezo ndi magulu ankhondo: 

Zolemba:zomangira mapulaneti odzigudubuza amapangidwa makamakazomangira, zodzigudubuza, mtedza, mphete zamkati zamkati, khola ndi mphete zotanuka;

Zoyenda:zomangira mapulaneti odzigudubuza mu ntchito, wononga nthawi zambiri ntchito monga athandizira mphamvu, kokha mozungulira olamulira ake kasinthasintha; nati nthawi zambiri imalumikizidwa ndi katundu, pokhapokha pamayendedwe ake; wodzigudubuza mu mtedza ndi kayendedwe ka mapulaneti pakati pa wononga ndi kusuntha kwa axial kwa mtedza wokhudzana ndi ziro, ndi mtedza pamodzi ndi kayendetsedwe ka axial.

Ndi pulaneti yodzigudubuza m'mafakitale osiyanasiyana ikupitirizabe kuzama, zochitika zake zogwiritsira ntchito zimabweranso mochulukira, kuti zigwirizane ndi malo osiyanasiyana ogwiritsira ntchito komanso kuyika, mawonekedwe a mawonekedwewo amakhalanso akutukuka kosalekeza. Standard, cyclic, reverse, differential ndi zina zomangira mapulaneti zimagwiritsidwa ntchito kwambiri:

(1) Mtundu wokhazikika: Nthawi zambiri, screw ndiye membala yogwira ndipo nati ndiye membala wotuluka. Ikhoza kukwaniritsa kupwetekedwa kwakukulu, koyenera kumadera ovuta, kulemedwa kwakukulu, kuthamanga kwambiri ndi zochitika zina, makamaka zomwe zimagwiritsidwa ntchito mwatsatanetsatane zida zamakina, ma robot, zida zankhondo ndi madera ena, pakali pano ndi mtundu wogwiritsidwa ntchito kwambiri;

(2) Mtundu wopindika: mawonekedwe ake amafanana ndi mtundu wamba, kusiyana kwake ndikuti ilibe mphete yamkati yamagetsi, mano owongoka kumapeto onse a ma screw mesh ndi magiya kumapeto onse a chodzigudubuza, ndi nati monga gawo logwira ntchito, lomwe kutalika kwake ndi lalikulu kwambiri kuposa la mtundu wokhazikika. Nthawi zambiri, mtedza wawononga pulaneti yozungulira screwndi membala yogwira, wononga ndi membala linanena bungwe, ndipo palibe wachibale axial kusamutsidwa pakati wodzigudubuza ndi wononga, amene makamaka ntchito katundu ang'onoang'ono ndi sing'anga-kakulidwe, zikwapu ang'onoang'ono ndi zochitika mkulu-liwiro ntchito, ndi waukulu kwambiri. ubwino ndi kuti mtedza wake angagwiritsidwe ntchito ngati galimoto rotor kukwaniritsa Integrated kamangidwe ka galimoto ndi wononga kupanga yaying'ono-chidutswa electro-mechanical actuator;

(3) Mtundu wobwerezabwereza: Poyerekeza ndi mtundu wamba, imachotsa mphete yamkati ya gear ndikuwonjezera mawonekedwe a mphete ya cam, yomwe ntchito yake imakhala yofanana ndi yobwezera mpira, kuti wodzigudubuza abwerere kumalo oyambirira pambuyo pozungulira. mu mtedza kwa sabata imodzi. The structural makhalidwe arecirculating pulaneti wodzigudubuza screwonjezerani chiwerengero cha ulusi wokhudzidwa ndi chinkhoswecho, kotero chimakhala ndi kuuma kwakukulu ndi katundu wambiri, ndipo chimagwiritsidwa ntchito makamaka pa ntchito zomwe zimafuna kuuma kwakukulu, kulemera kwakukulu, ndi kulondola kwakukulu, monga zida zachipatala, zida zowoneka bwino, ndi zina. . Choyipa ndichakuti mawonekedwe ake a mphete ya cam adzatulutsa kugwedezeka, pali vuto laphokoso;

(4) Mtundu wosiyana: Poyerekeza ndi mtundu wokhazikika, mphete yamkati ya gear imachotsedwa ndipo palibe gawo la gear pa roller. The structural makhalidwe a differential mapulaneti wodzigudubuza wononga kumapangitsa kupeza kutsogolera ang'onoang'ono, amene ali oyenera ntchito ndi zikuluzikulu kufala ziwerengero ndi apamwamba katundu katundu. Komabe, pakuyenda kwake, ulusiwo udzatulutsa chodabwitsa, chomwe chimakonda kuvala pansi pa katundu wolemetsa, zomwe zimayambitsa kutayika kolondola, kuchepetsa kudalirika ndi mavuto ena.

Chowotcha chozungulira chopindika mu cholumikizira cha mzere

Kulowera kwa mapulaneti ozungulira kumayembekezeredwa kuwonjezeka, m'malo mwa gawo la zomangira za mpira ndi ma hydraulic transmissions:

(1) Poyerekeza ndi kufala kwa zomangira mpira, zomangira mapulaneti wodzigudubuza ndi mphamvu kunyamula mphamvu, angagwiritsidwe ntchito mu zovuta ndi nkhanza zikhalidwe ntchito, moyo wautali ndi ubwino zina, akuyembekezeka ntchito m'munda wa zida makina, robotic magetsi. ma silinda ndi zochitika zina;

(2) Kutengera pulaneti wodzigudubuza wononga mwatsatanetsatane kufala kufala, kuti agonjetse chikhalidwe hayidiroliki kufala chipangizo chibadidwe chilengedwe kusinthasintha, kudalirika otsika, kugwiritsa ntchito bwino kukonza ndi zofooka zina, akuyembekezeka m'malo mbali ya chochitika hayidiroliki kufala chipangizo.
