Isakhiwo esijwayelekile se-swing cylinder radial piston motor

Umfanekiso B ubonisa ukwakheka kwe-swing cylinder radial piston motor enokusabalalisa kobuso ekugcineni. Amafutha okucindezela angena ku-piston cylinder esuka ku-trunnion 13, futhi umzimba we-cylinder uzungeza i-trunnion ngesikhathi sokusebenza. Awekho amandla ahlangene phakathi kwe-plunger 12 nesilinda sokushwiba, futhi cishe akukho ukuguga phakathi kwakho. Iphansi le-plunger liklanywe njengebhalansi ye-static pressure, futhi amandla adluliselwa phakathi kwe-plunger ne-crankshaft 3 ngokusebenzisa i-rolling bear 11. Lezi zinyathelo zinciphisa ukulahlekelwa kwe-friction ohlelweni lokudlulisa amandla, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwemishini yenjini. Ukusebenza kahle kwe-hydraulic mechanical motor, ikakhulukazi esimweni sokuqala, kungafinyelela ku-90%, ngakho-ke i-torque yokuqala inkulu kakhulu. Ngaphezu kwalokho, ukuvuza kuncishisiwe kakhulu futhi ukuthembeka kuthuthukiswa ngokusebenzisa ubuchwepheshe bokusabalalisa ukugeleza kobuso bokuphela; i-plastic piston ring seal isetshenziswa phakathi kwepiston nesilinda sokushwibeka, esingafinyelela cishe ukungavuzi futhi kuthuthukise kakhulu ukusebenza kahle kwevolumu. Lolu hlobo lwemoto lunozinzo oluhle ngejubane eliphansi futhi lungasebenza kahle ngesivinini esiphansi kakhulu (ngaphansi kuka-1 R/min). Ibanga lokulawula isivinini nalo likhulu kakhulu, futhi isilinganiso sokulawulwa kwejubane (isilinganiso sejubane eliphezulu kakhulu nesiphansi kunazo zonke esizinzile) singafinyelela ku-1000. Ngenxa yesakhiwo sayo esilula, ukuklama okunengqondo nokuthwala umthamo omkhulu womthwalo, i-motor inezinzuzo zevolumu encane, isisindo esincane, ukusebenza okuthembekile, impilo ende nomsindo ophansi. Isibalo esingezansi sibonisa isimo somzimba we-swing cylinder fixed displacement radial piston motor.

③ I-Hydrostatic balance radial piston motor lolu hlobo lwenjini lubizwa nangokuthi i-hydrostatic balance motor, okungeyona ye-rod motor exhumayo, futhi ukwakheka kwayo kuboniswa kuMfanekiso C.

Kunamasilinda ama-plunger amahlanu (anenombolo IV) asatshalaliswe ngokulinganayo eduze kwesiqondiso se-radial endlini engu-4 yemoto, futhi ama-plunger amahlanu 2 afakwe ngokulandelana kwawo kumasilinda e-plunger endlu. Lolu hlobo lwemoto lukhansela induku yokuxhuma, kanti isondo lezinkanyezi ezinhlanu u-5, elifakwe ku-eccentric 1 ye-crankshaft 6, lisebenza njengenduku yokuxhuma. Imbobo ngayinye kweziyisihlanu ze-radial yesondo lezinkanyezi ezinhlanu ishunyekwe ngendandatho yokucindezela engu-7, futhi ubuso obungaphezulu besiphetho sendandatho yokucindezela kanye ne-plunger kunikezwa okuphakathi okuhambisanayo nezimbobo. I-Crankshaft 6 isekelwa i-pair of tapered roller bearings 8, enye ingxenye yayo i-shaft ephumayo eyandisiwe, kanti enye iphethe ihlinzekwa ngama-annular grooves (C kanye no-D) ngokulandelanayo axhunywe ne-oil inlet kanye namachweba okubuyisela u-A no-B kumqoqi wamanje 10. Imigqa emibili yenziwa ngomshini engxenyeni ephakathi nendawo, i-crank yesondo emibili. ngokulandelana okuxhunywe nendawo yokungena kawoyela kanye ne-outlet a no-B ngembobo ye-axial kanye ne-annular groove ku-crankshaft.

Lapho i-motor isebenza, uwoyela we-high-pressure ungena kumqoqi wamanje ongu-10 usuka echwebeni a, udlule endaweni eyi-annular groove D ye-crankshaft, imbobo ye-axial kanye negumbi lechweba ohlangothini lwesobunxele lwe-eccentric, lingena emgodini ophakathi kwegiya lezinkanyezi ezinhlanu, indandatho yokucindezela kanye ne-plunger, futhi ifinyelela ku-cypress IV ephezulu ku-V. Uwoyela wengcindezi ephezulu usebenza ngqo ku-eccentric ye-crankshaft, futhi amandla awo angumphumela enza i-torque enkabeni yokuzungezisa ye-crankshaft phakathi nendawo ye-eccentric (i-eccentricity ingu-e), ukuze i-crankshaft izungezise ngokwewashi. Ngemuva kokuguqula i-engeli, isilinda I nayo ixhunywe negumbi lokucindezela okuphezulu. Ngale ndlela, amasilinda amabili noma amathathu anikezwa uwoyela ocindezelayo ngokushintshana. Enqubweni yokusebenza yenjini, isondo lezinkanyezi ezinhlanu lihamba endizeni ngokuhlobene ne-plunger, kuyilapho i-plunger ihamba phezulu naphansi. Ngesikhathi sokuqalisa noma ukungalayishi, amandla okunwebeka entwasahlobo 3 ku-plunger engenalutho anqoba ukungqubuzana phakathi kwe-plunger nodonga lwesilinda, ukuze indawo engaphansi ye-plunger isondelene eduze nendandatho yokucindezela. Lapho ushintsha isiqondiso sokugeleza kwe-inlet ne-outlet, injini izohlehla. Lolu hlobo lwenjini lunakho kokubili uhlobo lokujikeleza kwe-crankshaft kanye nohlobo lokuzungezisa igobolondo. Ngenxa yokuthi i-crankshaft ilungisiwe, umkhono we-valve 9 ungashiywa, okwenza kube lula ukwakheka futhi kunciphise izindleko. I-motor ene-double extension shaft ingathwala umthwalo omningi kune-motor ene-extension shaft eyodwa. Ukuze kwandiswe i-torque, i-hydrostatic balancing motor ene-double row plunger (amasondo amabili eccentric) kwesinye isikhathi yenziwa. Ukuze wenze i-radial force kubhalansi ye-crankshaft enye nenye, izikhombisi-ndlela zamasondo amabili eccentric zihluke ngo-180 °.

Uma kuqhathaniswa ne-motor yohlobo lwe-rod yokuxhuma, i-hydrostatic balancing motor inezici ezilandelayo: i-crankshaft inomsebenzi wokudlulisa amandla nokusabalalisa shaft, ngakho-ke ubukhulu be-axial bemoto buncane; ukufaka esikhundleni senduku yokuxhuma ngesondo lezinkanyezi ezinhlanu kungenza kube lula ukwakheka kanye nenqubo, futhi kunciphise ubukhulu be-radial; kodwa-ke, ukukhanselwa kwenduku yokuxhuma kuholela ekwandeni kwamandla angemuva phakathi kwe-plunger ne-cylinder bore, kanye nokushelela phakathi kwesondo lezinkanyezi ezinhlanu kanye nendawo engezansi ye-plunger, naphakathi kwesondo lezinkanyezi ezinhlanu kanye nesondo le-eccentric Ukulahlekelwa kwe-friction yesihlobo phakathi kwezindawo ezihambayo kukhulu kakhulu, okuthinta ukusebenza kahle kwe-motor. Uwoyela ocindezelayo usebenza ngokuqondile esondweni le-eccentric le-crankshaft ukwenza i-torque futhi wenze i-crankshaft ijikeleze. Ngalesi sikhathi, ukucindezela kwe-hydraulic ku-plunger, indandatho yokucindezela kanye nesondo lezinkanyezi ezinhlanu kuseduze nebhalansi ye-static pressure. Ngakho-ke, emsebenzini, i-plunger, indandatho yokucindezela kanye nesondo lezinkanyezi ezinhlanu kuphela kudlala indima yokuvala yokungenzi ukuvuza kwamafutha okucindezela, ngakho kubizwa ngokuthi i-static pressure Pressure balance motor.
