Khoom Taw qhia

Bolt lub tes tsho rau hlau yog cov khoom tseem ceeb los txhim kho qhov zoo ntawm kev sib txuas bolted. Cov kev ntsuam xyuas tiag tiag qhia tau tias tom qab kev txhim kho carbon steel casing nrog phab ntsa thickness ntawm 1.5 hli, lub torque fluctuation amplitude yog txo los ntawm ± 18% mus rau ± 6%. Qhov no ho txhim kho preload tswj raug. Lub cylindricity kam rau ua ntawm siab - zoo casing tuaj yeem tswj tau li ntawm 0.1 hli. Qhov no xyuas kom meej concentricity ntawm lub bolt rau lub qhov phab ntsa. Qhov no tuaj yeem zam kev puas tsuaj los ntawm kev thauj khoom tsis sib npaug. Yog li ntawd, lub tes tsho hlau txhim kho kev sib dhos thiab kev ntseeg tau.

Kev ntsuam xyuas tau pom tias tsis muaj lub casing, thawj xov dais 35% ntawm tag nrho cov axial load. Tom qab txhim kho lub tes tsho nrog qhov ntev ntawm peb npaug ntawm txoj kab uas hla, qhov sib piv no poob mus rau 24%. Qhov no tsis txhob qaug zog tawg ntawm cov xov hauv paus. Qhov sib txawv ntawm thermal expansion coefficient ntawm lub tes tsho carbon steel thiab steel bolt yog 0.5 × 10⁻⁶ ib Kelvin. Ntawm qhov sib txawv ntawm qhov kub ntawm 50 degrees Celsius, qhov thermal stress tsawg dua 2 MPa. Yog li ntawd, lub preload quab yuam tsis hloov pauv loj.

Qhov zoo

Qhov chaw yooj yim

Cov pa roj carbon steel lossis stainless hlau casings tuaj yeem ua qhov chaw welded ncaj qha rau cov qauv hlau kom ua tiav ua ntej - qhov chaw, thiab vuam lub zog tuaj yeem ncav cuag ntau dua 70% ntawm lub zog tensile ntawm cov khoom siv hauv paus. Piv txwv li, rau lub casing nrog lub thickness ntawm 2 hli, lub rub- tawm quab yuam tom qab qhov chaw vuam tshaj 5 kN. Cov yam ntxwv no ua kom yooj yim tso rau ntawm lub tes tsho ntawm cov kab sib dhos, txo cov nqi ntxiv, thiab ua kom cov khoom ua tau zoo li ntawm 25%.

High hardness thiab anti-indentation

Qhov tawv tawv ntawm cov cua sov-kho stainless hlau casing tuaj yeem ncav cuag 250 HB, uas yog ntau dua 40% siab dua li cov hlau me me. Nyob rau hauv siab -lub zog bolted kev sib txuas, txawm tias lub preload quab yuam ua rau kev sib cuag kev nyuaj siab tshaj 300 MPa, yuav tsis muaj qhov pom tseeb indentation ntawm lub casing nto. Qhov no ua kom lub tiaj tus ntawm lub taub hau ntsia liaj qhov rooj los yog cov txiv ntoo bearing nto, tswj lub siab tsis sib xws ntawm lub gasket, thiab tiv thaiv kom tsis txhob tawm.

Cov khoom siv tiv thaiv

Nyob rau hauv ib puag ncig kev co, fretting hnav ntawm bolts thiab lub qhov phab ntsa yuav ua rau lub hauv paus ntawm lub cev puas. Lub stainless hlau casing yog ib qho nyuaj tshaj li cov aluminium-magnesium alloy puag (250 HB vs 80 HB), uas concentrates hnav ntawm lub casing hloov tau. Cov kev ntsuam xyuas qhia tau hais tias tom qab 2 lab micro- lub voj voog ncig, qhov hnyav ntawm cov khoom siv hauv paus tsuas yog 5% ntawm qhov tsis muaj lub casing. Qhov no cuam tshuam rau lub neej kev pab cuam ntawm cov khoom tseem ceeb xws li cov cav cav.

Tiv thaiv kev nkag mus

Thaum txuas cov phaj nyias (thickness Tsawg dua los yog sib npaug li 2 hli), lub bolt pretightening quab yuam tau yooj yim ua rau cov phaj nyias nyias los yog cov txiv ntseej rau hauv dej. Lub tes tsho hlau tuaj yeem ua rau thaj tsam kev ntxhov siab thiab cuam tshuam kev sib cuag compressive kev ntxhov siab los ntawm 500 MPa mus rau tsawg dua 50 MPa. Cov kev sim qhia tau hais tias tom qab siv lub casing nrog ib tug ntev ob zaug lub thickness ntawm lub phaj, lub deformation ntawm nyias phaj yog txo los ntawm 85%, thiab lub bolt torque yuav xyuam xim siv rau lub hom phiaj tus nqi, tag nrho cov kev daws teeb meem "kev nkag mus" ntawm nyias phaj kev twb kev txuas.

vim li cas xaiv peb

►Functional txheej muaj

Lub tes tsho hlau tuaj yeem ua electroplated nrog nyiaj, tin, cadmium thiab lwm yam txheej. Kev tiv thaiv kev tiv thaiv ntawm cov nyiaj -plated bushing yog tsawg dua 0.5 mΩ thiab tsim nyog rau kev sib txuas loj tam sim no; lub tin -plated bushing muaj zoo heev solderability thiab yog yooj yim rau vuam thiab kho cov av xaim.

►Tau tshaj tus qauv fasteners

Sab hauv txoj kab uas hla ntawm cov hlau casing yog tsim raws li GB / T, DIN, thiab ISO cov qauv thiab tuaj yeem ncaj qha rau cov khoom lag luam muaj cov qauv bolts. Cov nqi yuav khoom tuaj yeem txuag tau ntau dua 30%.

►Muaj peev xwm tiv taus siab preload torques

Lub pretightening torque exerted los ntawm hluav taws xob torque wrench tuaj yeem ncav cuag ntau tshaj 500 N·m. Lub tes tsho hlau yuav tsis plam los yog nti zoo li cov yas, kom ntseeg tau tias kev sib kis ntawm torque mus rau lub bolt thiab tsis txhob sib dhos ua haujlwm.

►Yooj yim rau ntawm - hloov kho qhov chaw

Yog tias qhov ntev yuav tsum tau hloov kho thaum lub sijhawm ntawm - qhov chaw teeb tsa, cov hlau casing tuaj yeem raug txiav nrog lub tes pom zoo tib yam lossis lub kaum sab xis. Qhov kawg nto tom qab txiav yog tiaj tus thiab tsis cuam tshuam rau kev siv. Txiav yas casing yog nquag burrs los yog tawg, thiab kev hloov dua siab tshiab yog tsawg.
