Mapangidwe a multiplate friction clutch ndi ake ndi mfundo yogwirira ntchito

Multi-plate friction clutch ndi mtundu wa njira yotumizira ma torque yomwe imakhala ndi paketi ya friction ndi ma disc achitsulo. Mphindi imafalikira chifukwa cha mphamvu yothamanga yomwe imachitika pamene ma diski amapanikizidwa. Ma multiplate clutch amagwiritsidwa ntchito kwambiri pamagawo osiyanasiyana otumizira magalimoto. Ganizirani za chipangizocho, mfundo ya ntchito, komanso ubwino ndi kuipa kwa njirazi.

Mfundo yogwiritsira ntchito clutch

Ntchito yayikulu ya ma multiplate clutch ndikulumikiza bwino ndikuchotsa zolowetsa (drive) ndi zotulutsa (zoyendetsedwa) pa nthawi yoyenera chifukwa champhamvu yakukangana pakati pa ma disks. Pankhaniyi, torque imasamutsidwa kuchokera kutsinde limodzi kupita ku lina. The zimbale ndi wothinikizidwa ndi madzimadzi kuthamanga.

Chonde dziwani kuti mtengo wa torque wopatsirana ndiwokulirapo, kulimba kwa malo olumikizana ndi ma disc. Panthawi yogwira ntchito, clutch imatha kutsetsereka, ndipo shaft yoyendetsedwa imathamanga bwino popanda kugwedezeka kapena kugwedezeka.

Kusiyanitsa kwakukulu kwa makina opangira ma multi-disk kuchokera kwa ena ndikuti pakuwonjezeka kwa ma disks, kuchuluka kwa malo okhudzidwa kumawonjezeka, zomwe zimapangitsa kuti zitheke kufalitsa torque yambiri.

Maziko a ntchito yachibadwa ya mikangano clutch ndi kukhalapo kwa kusiyana chosinthika pakati pa zimbale. Nthawi imeneyi iyenera kugwirizana ndi mtengo wokhazikitsidwa ndi wopanga. Ngati kusiyana pakati pa ma clutch discs ndi ocheperapo mtengo womwe watchulidwa, ziwombankhangazo zimakhala mu "compressed" nthawi zonse ndipo zimatha mwachangu molingana. Ngati mtunda uli waukulu, kutsetsereka kwa clutch kumawonedwa panthawi yogwira ntchito. Ndipo pamenepa, kuvala mofulumira sikungapewedwe. Kusintha kolondola kwa mipata pakati pa zomangira pokonza kugwirizanitsa ndiko chinsinsi cha ntchito yake yolondola.

Zomangamanga ndi zigawo zikuluzikulu

Multi-plate friction clutch ndi paketi yachitsulo ndi ma alternating friction discs. Chiwerengero chawo mwachindunji zimatengera torque yomwe iyenera kufalikira pakati pa ma shafts.

Choncho, pali mitundu iwiri ya washers mu clutch - zitsulo ndi mikangano. Kodi pali kusiyana kotani pakati pawo Chowonadi ndi chakuti mtundu wachiwiri wa pulley uli ndi zokutira zapadera zotchedwa "kukangana". Zimapangidwa ndi zida zowotcha kwambiri: zoumba, zopangira kaboni, ulusi wa Kevlar, etc.

Ma disks omwe amapezeka kwambiri ndi ma disks achitsulo okhala ndi wosanjikiza. Komabe, sizikhala zachitsulo nthawi zonse; nthawi zina zida zophatikizirazi zimapangidwa ndi pulasitiki yolimba. Ma disks amamangiriridwa ku shaft hub ya drive.

Ma disks wamba osasunthika amayikidwa mu ng'oma yolumikizidwa ndi shaft yoyendetsedwa.

Clutch ilinso ndi pisitoni ndi kasupe wobwerera. Pansi pa kuthamanga kwamadzimadzi, pisitoni imakankhira pa disk pack, ndikupanga mphamvu yolimbana pakati pawo ndikutumiza torque. Kupanikizika kumatulutsidwa, kasupe amabwezeretsa pisitoni ndipo clutch imatulutsidwa.

Pali mitundu iwiri ya ma multiplate clutches: youma ndi yonyowa. Mtundu wachiwiri wa chipangizocho umadzazidwa pang'ono ndi mafuta. Kupaka mafuta ndikofunikira pa:

• kutentha kwabwino kwambiri;
• Kupaka ziwalo za clutch.

Clutch yonyowa yamitundu yambiri imakhala ndi vuto limodzi - kugundana kocheperako. Opanga amalipiritsa kuipa kumeneku powonjezera kukakamiza kwa ma diski ndikugwiritsa ntchito zida zaposachedwa kwambiri.

Ubwino ndi kuipa

Ubwino wa multiplate friction clutch:

• kuphatikiza;
• Mukamagwiritsa ntchito ma multiplate clutch, miyeso ya unit imachepetsedwa kwambiri;
• kufalitsa makokedwe ofunikira ndi miyeso yaying'ono yamakina (powonjezera kuchuluka kwa ma disks);
• kusalala kwa ntchito;
• kuthekera kolumikiza shaft yoyendetsa ndi shaft yoyendetsedwa ndi coaxially.

Komabe, makinawa ali ndi zovuta zake. Mwachitsanzo, zitsulo ndi mikangano zimbale akhoza kuwotcha pa ntchito. M'magulu onyowa amitundu yambiri, kugundana kwamphamvu kumasinthanso ngati kukhuthala kwamafuta kumasintha.

Lumikiza ntchito

Ma multiplate clutch amagwiritsidwa ntchito kwambiri pamagalimoto. Chipangizochi chimagwiritsidwa ntchito pamakina otsatirawa:

• clutch (mu CVTs popanda chosinthira makokedwe);
• Kutumiza kwa Automatic (kutumiza kwaotomatiki): Clutch yotumizira yodziwikiratu imagwiritsidwa ntchito kutumizira ma torque ku seti ya zida za pulaneti.
• Ma gearbox a robot: Paketi yapawiri clutch disc mu bokosi la roboti imagwiritsidwa ntchito posuntha pa liwiro lalikulu.
• Makina oyendetsa ma gudumu onse: chipangizo cholumikizira chimapangidwa muchotengera chosinthira (cholumikizira chimafunikira pano kuti chitsekeredwe chosiyana chapakati);
• Kusiyanitsa: chipangizo chamagetsi chimagwira ntchito yotsekereza kwathunthu kapena pang'ono.
