Rigid Universal Joint Ib qho kev sib koom ua ke thoob ntiaj teb yog ib hom kev sib koom ua ke thoob ntiaj teb uas tsis muaj qhov elasticity tseem ceeb hauv cov kev taw qhia torsional. Nws tuaj yeem muab faib ua cov tsis yog - qhov nrawm nrawm universal pob qij txha thiab quasi - qhov nrawm nrawm universal pob qij txha.
① Tsis yog - tsis tu ncua kev sib tw universal sib koom. Thaum lub kaum sab xis nyob nruab nrab ntawm ob lub shafts txuas los ntawm kev sib koom ua ke thoob ntiaj teb yog ntau dua li xoom, cov zis ncej thiab cov khoom siv nkag mus xa cov lus tsa suab nrog qhov sib txawv ntawm qhov sib txawv ntawm qhov nrawm nrawm, tab sis qhov nruab nrab angular tshaj tawm yog sib npaug.
Ib tug ntoo khaub lig- ncej hom nruj universal sib koom tes muaj ib tug universal sib koom diav rawg, ib tug ntoo khaub lig ncej, rab koob rau cov menyuam bearings, roj foob, lub tes tsho, thiab cov kabmob caps. Nws txoj haujlwm ua haujlwm yog raws li hauv qab no: tig ib qho ntawm rab rawg tsav lwm rab diav rawg kom tig los ntawm tus ntoo khaub lig ncej, thaum tib lub sijhawm tso cai rau nws mus oscillate nyob rau hauv ib qho kev taw qhia nyob ib ncig ntawm qhov chaw ntawm tus ntoo khaub lig ncej. Thaum lub sij hawm kev sib hloov, cov koob chais rau hauv rab koob rau cov menyuam bearings tuaj yeem tig ntawm lawv tus kheej kom tsis txhob muaj kev sib txhuam. Cov ncej txuas nrog lub zog hluav taws xob yog hu ua input ncej (tseem hu ua lub tshuab tsav tsheb), thiab cov ncej tawm los ntawm kev sib koom ua ke thoob ntiaj teb yog hu ua cov zis ncej (tseem hu ua cov ncej tsav). Thaum ua haujlwm nyob rau hauv cov xwm txheej uas muaj lub kaum sab xis ntawm cov tswv yim thiab cov zis tawm, lub kaum sab xis ntawm ob lub shafts tsis sib npaug, uas yuav ua rau torsional vibration hauv cov zis ncej thiab nws cov khoom sib txuas, cuam tshuam rau lub neej ntawm cov khoom no.
② Quasi- qhov nrawm nrawm universal sib koom. Qhov no yog hais txog kev sib koom ua ke thoob ntiaj teb uas xa cov lus tsa suab nrog qhov sib npaug ntawm qhov nrawm nrawm ntawm lub kaum sab xis tsim, thiab nrog kwv yees li qhov sib npaug ntawm qhov nrawm nrawm ntawm lwm lub kaum. Nws tau muab faib ntxiv rau hauv: a) Ob npaug -jointed quasi- qhov nrawm nrawm universal sib koom. Qhov no yog hais txog kev sib koom ua ke thoob ntiaj teb uas tus tsav ncej ntev nyob rau hauv qhov tsis tu ncua kev sib kis ntaus ntawv yog luv luv rau nws qhov tsawg kawg nkaus. b) Protrusion- hom quasi- qhov nrawm nrawm universal sib koom. Qhov no muaj ob lub universal pob qij txha thiab ob lub protrusions ntawm cov duab sib txawv. Ob lub protrusions yog sib npaug rau nruab nrab tsav ncej thiab ob tug ntoo khaub lig pins nyob rau hauv ib tug ob -kos universal sib koom ntaus ntawv. c) Peb-pin hom quasi- qhov nrawm nrawm universal sib koom. Qhov no muaj ob peb -pin shafts, ib tug tsav tsheb eccentric ncej diav rawg, thiab ib tug tsav eccentric ncej diav rawg. d) Spherical roller type quasi- qhov nrawm nrawm universal sib koom. Qhov no muaj cov pins, spherical rollers, universal joint ncej, thiab lub tog raj kheej. Cov rollers tuaj yeem txav axially hauv qhov zawj, ua raws li lub telescopic spline. Kev sib cuag ntawm cov yob thiab cov phab ntsa zawj kis torque.
Flexible Universal Joint
Ib qho yooj yim universal sib koom ua ke yog universal sib koom ua ke uas nthuav tawm qhov elasticity tseem ceeb hauv kev taw qhia torsional.
Ib qho yooj yim universal sib koom ua ke feem ntau muaj cov roj hmab elastic (cov roj hmab disc, roj hmab thaiv, roj hmab nplhaib, roj hmab- tes tsho hlau, thiab lwm yam), bushings, bolts, thiab cov cuab yeej nruab nrab kom ntseeg tau tias muaj kev sib npaug ntawm kev kub ceev. Nws lub hauv paus ntsiab lus ua haujlwm yog tias thaum lub zog ua haujlwm ntawm cov khoom siv nkag, lub torque kis tau los ntawm cov khoom siv nkag, peb lub flanges ntawm lub universal sib koom diav rawg, thiab cov bolts txuas, ces mus rau cov roj hmab thaiv. Lub torque ces ua rau universal sib koom flange ntawm cov zis ncej los ntawm cov roj hmab thaiv. Vim tias cov roj hmab thaiv yog elastic, qee lub kaum sab xis raug tso cai ntawm ob lub shafts.
