Chinofambisa Rack nePinion
Chii chinonzi Rack and Pinion actuator?
Zvishandiso zvemhepo zvinofambisa mapuranga neminhenga, inonziwo ma cylinders ekutenderera akaganhurirwa, iactuator dzinotenderera dzinoshandiswa pakutendeudza, kuvhura, kuvhara, kusanganisa, kuzunguza, kuisa panzvimbo, kutungamira uye mamwe mabasa akawanda emakanika ane chekuita nekutenderera kwakaganhurirwa. Aya ma actuator anowanzo shandiswawo pakuita otomatiki mavharuvhu ekutenderera kwekota, senge mavharuvhu ebhora kana butterfly.
Zvishandiso zvepneumatic rack-and-pinionshandura simba remhepo yakamanikidzwa uchishandisa silinda yemhepo kuita kufamba kunotenderera kunotenderera. Gasi rakachena, rakaoma, uye rakagadziriswa rinodiwa neactuator iyi rinopihwa kuburikidza nechiteshi chemhepo chakamanikidzwa chepakati, icho chinowanzo tsigira michina yakasiyana-siyana yemhepo muhurongwa hwekuita.
Zvinhu zvikuru zveRack nePinion actuator
Zvichienzaniswa nezvikamu zvavo zvemagetsi,Zvishandiso zveRack nepinion Kazhinji dzinogara kwenguva refu, dzakakodzera nzvimbo dzine njodzi uye hadzidhuri zvakanyanya. Pamusoro pezvo, dzinowanzo da kugadziriswa kushoma uye dzinopa simba rakawanda kana tichienzanisa nehukuru hwadzo.
Tsanangudzo yehunyanzvi yeRack nePinion actuator
Dhizaini yeraki imwe chete kana kuti yeraki mbiri
Ma "rack-and-pinion actuators" anopa torque ne "rotation" yakakura kwazvo zvichienzaniswa nedzimwe nzira dzekushandura simba re "linear force" kuita "rotational torque". Ane simba repamusoro re "mechanical efficiency" uye ma "torque" avanokwanisa kugadzira anotangira paNm mbiri kusvika kuzviuru zvakawanda zveNm.
Zvisinei, chimwe chinhu chingave chakaipa pakugadzirwa kwe rack-and-pinion i backlash. Backlash inoitika kana ma rack ne pinion gear asina kunyatsoenderana uye paine mukaha mudiki pakati pekubatanidza kwega kwega kwe gear. Kusarongeka uku kunogona kukonzera kusakara kwemagiya panguva yehupenyu hwe actuator, izvo zvinowedzera backlash.
Chigadziko che double rack chinoshandisa ma racks maviri kumativi akasiyana e pinion. Izvi zvinobatsira kubvisa backlash nekuda kwe counter force uye zvinowedzerawo torque yekubuda kweyuniti kaviri uye zvinowedzera kushanda zvakanaka kwemuchina we system. Mu double acting actuator inoratidzwa muMufananidzo 3, makamuri maviri ari kumativi akazadzwa nemhepo ine pressurized, iyo inosundira ma piston pakati uye kuti ma piston adzoserwe panzvimbo yekutanga, kamuri riri pakati rinozomanikidzwawo.
Basa
Ma "rack-and-pinion pneumatic actuators" anogona kushanda kamwe chete kana kaviri. Zvinokwanisikawo kuti ma "actuators" aya agone kumira kakawanda.
Kutamba kwemunhu mumwe chete vs. kuita kwemunhu mumwe chete
Mumuchina wemagetsi unoshanda kamwe chete, mweya unongopihwa kune rumwe rutivi rwepiston uye ndiwo unotungamira kufamba kwepiston munzira imwe chete. Kufamba kwepiston nenzira yakatarisana kunoitwa nechitubu chemakanika. Magadzirirwo anoshanda kamwe chete anochengetedza mweya wakamanikidzwa, asi anoita basa nenzira imwe chete. Dambudziko remasilinda anoshanda kamwe chete isimba risingawirirane rinobuda kuburikidza nekumhanya kwakazara nekuda kwesimba rechitubu rinopikisana. Mufananidzo 4 unoratidza muchina wemagetsi unoshanda kamwe chete une rack mbiri.
Muchishandiso chemagetsi chinoshanda kaviri, mweya unoendeswa kumakamuri ari kumativi ese episton. Kumanikidzwa kwemhepo kwakanyanya kune rumwe rutivi kunogona kuendesa piston kune rumwe rutivi. Mashandiso emagetsi anoshandiswa kaviri anoshandiswa kana basa richida kuitwa kumativi ese ari maviri. Mufananidzo 5 unoratidza chishandiso chemagetsi chinotenderera chine simba remagetsi chinobata kaviri.
Chimwe chezvakanakira zvemasirinda anoshanda kaviri isimba rinobuda nguva dzose kuburikidza nekutenderera kwakazara. Zvakaipa zvemasirinda anoshanda kaviri ndekuda kwavo mweya wakamanikidzwa kuti ufambe munzira dzese uye kushaya nzvimbo yakatarwa kana simba kana kumanikidzwa kukakundikana.
Nzvimbo dzakawanda
Mamwe ma "rack-and-pinion actuators" anokwanisa kumira panzvimbo dzakasiyana-siyana kuburikidza nekudzora kumanikidzwa pama "ports". Nzvimbo dzekumira dzinogona kuva mune chero kutevedzana, zvichiita kuti actuator ikwanise kupfuura nepakati pe "inter-mediate stop position".
Mabhaudhi ekumira kufamba
Mabhaudhi ekumira kufamba ari padivi pemuviri weactuator (sezvinoonekwa paMufananidzo 6) uye anobvumira kugadziriswa kwenzvimbo dzekupedzisira dzemapiston nekuderedza kutenderera kwegiya repinion kubva mukati. Paunenge uchiisa actuator, tyaira mabhaudhi ese ari maviri ekumira kufamba kusvika abatana nekavha yekumira kufamba. Ramba uchikwesha bhaudhi rekumira kuruboshwe kusvika nzvimbo yepinion inoonekwa pamusoro yatenderera kuenda kunzvimbo yakafanana nehurefu hwemuviri weactuator.
Chikumbiro Chechigadzirwa: chikamu chinoshandura magetsi
Nekuda kwesimba ravo remagetsi risingaperi,Zvishandiso zveRack nepinionanoshandiswa kakawanda uye kazhinji ndiwo maitiro anonyanya kufarirwa ezvishandiso zvepneumatic zvemavharuvhu. Anoshandiswa pakusanganisa, kurasa marara, kupa chikafu nguva nenguva, kutenderera nguva dzose, kutenderedza, kuisa panzvimbo, kuzunguza, kusimudza, kuvhura nekuvhara nekutenderedza. Aya maactuator anoshandiswa pamabasa akasiyana-siyana emakanika muindasitiri yesimbi, kubata zvinhu, mabasa egungwa, michina yekuvaka, michina yekuchera migodhi, uye hydraulic power steering.
