Trust screw xaiv txoj kev:
1. Paub tej yam kev mob: UPH, workbench zoo M1, itinerary ntev LS, siab tshaj plaws ceev VMAX, acceleration lub sij hawm T1 thiab T3, positioning raug ntxiv rau -0.3mm/1000mm, reciprocating ce voj voog, sib txawv 0.15 mm
Thib ob, xaiv cov khoom: ntsia hlau txoj kab uas hla, phau ntawv qhia, txiv ntseej qauv, qhov tseeb, axial kis, ntsia hlau kev txhawb nqa txoj kev, lub cev muaj zog
Thib peb, suav:
1. qhov tseeb thiab hom.
(Kev ncig mus ncig, axial gap) {{0}}.15mm, xaiv cov ntsia hlau nrog qhov sib txawv hauv qab no 0.15, kos lub rooj nrog cov ntsia hlau nrog txoj kab uas hla tsawg dua 32mm. 32mm clearance yog 0.14mm.
Yuav kom ua tau raws li qhov ntxiv rau -0.3mm/1000mm, ntxiv rau -0.3mm/1000=x/300
X {{0}} plus -0.09mm. Koj yuav tsum xaiv cov lus qhia qhov tseeb ntawm ± 0.090mm / 300mm lossis ntau dua. Pom qhov tseeb ntawm tus scioner, xaiv C7 ntsia hlau. Hom Aflery: Raws li lub koom haum, hom screws yog: dov los yog sib tsoo screws, positioning los yog kis tau tus mob
2. Qhia. (Xaiv cov hlaws dov thiab kev sib hloov ceev ntawm txoj kab ncaj nraim thiab kev sib hloov ceev)
The maximum speed of the guide and the motor pH> = 60*1000*v/(n/a)
(1.) pH: ntsia hlau qws qhia mm
(2.) V: Qhov siab tshaj plaws pub ceev M / s yog predetermined
() N: Tsav siv ceev RPM
() A: deceleration piv
3. Txoj kab uas hla. (Txiav txoj kab uas hla ntawm lub load) dynamic load thiab static load; xam thrust, feem ntau tsuas yog saib cov dynamic load
Kev suav ntawm axial load: U kev sib txhuam coefficient; ib=vmax/t acceleration; T kom ceev lub sij hawm deceleration;
Kab rov tav lub sij hawm: Ua qhov siab tshaj plaws axial load thaum lub sij hawm acceleration, kom tiv taus qhov tsawg kawg nkaus load thaum lub sij hawm deceleration; thaum ntsug: kom dais qhov siab tshaj plaws axial load thaum nce, qhov tsawg kawg nkaus load thaum txo; yam tsawg kawg nkaus load;
1. Thaum lub sij hawm acceleration (ascending) n: FMAX=u*m*g plus fm*A
2. Thaum lub sij hawm deceleration (txo) n: fmin=u*m*m*g plus fm*A
3. Nyob rau hauv qhov ceev tsis tu ncua, n: f txawm=u*m*g plus fu
Vim lub thinner txoj kab uas hla ntawm cov ntsia hlau ncej, qhov me me axial load ntawm cov ntsia hlau ncej
4. ntev. (Tag nrho ntev=ua hauj lwm stroke ntxiv txiv ntseej ntev ntxiv rau kev nyab xeeb tshuav nyiaj li cas ntxiv rau qhov ntev ntawm kev sib txuas ntxiv rau qhov ntev thiab qhov sib npaug). Yog tias qhov kev tiv thaiv tau nce ntxiv, xws li kev tiv thaiv npog, lub telescopic piv ntawm lub npog tiv thaiv (feem ntau yog 1: 8. Qhov siab tshaj plaws ntawm kev tiv thaiv npog yog muab faib ua 8).
5. Kev them nyiaj yug txoj kev. Tsau fixation-txhawb txhawb-txhawb fixation-kev ywj pheej
6. Kev xaiv ntawm txiv ntseej:
7. Siv ceev xam: ntsia hlau ncej inch 20mm, qhia pH=20mm siab tshaj ceev vmax=1m/s
Tom qab ntawd: qhov ceev tshaj plaws NMAX=vmax60/pH. Motoring ceev (tseem ceeb ceev) n1=r (d1/)*
Tus coefficient txiav txim los ntawm R installation txoj kev; D1=txhob lo lo ntxhuav groove txoj kab; L=nruab qhov sib nrug yog li: qhov siab tshaj plaws
8. Kev xaiv nruj
9. Xaiv qhov kev kuaj xyuas lub cev muaj zog: kev kuaj xyuas nruj, kev txheeb xyuas qib raug, kev xaiv lub neej, kev xaiv tsav torque
Cov menyuam ntsia hlau yog pre-tightened:
1. Txoj kev: Muab ob npaug rau txiv ntseej ntxuav, ua ntej-tightening, ua ntej-tightening ntawm ib tug txiv ntseej, thiab ua ntej-tightening ntawm txoj kab uas hla ntawm ib tug txiv ntseej kom nce txoj kab uas hla;
2. Lub Hom Phiaj: Tshem tawm qhov sib txawv ntawm qhov sib txawv ntawm lub nruas ntsia hlau sab, ua kom cov rigidity thiab DN tus nqi ntawm lub nruas ntsia hlau pawg: D: lub nominal txoj kab uas hla ntawm lub laum ntsia hlau sab, thiab txoj kab uas hla (mm) nyob rau hauv nruab nrab ntawm lub pob; Kev nrawm nrawm (RPM) kev taw qhia raug, qhov tseeb qhov chaw, rov ua qhov tseeb
Cov lus qhia raug:
1. Qhov nruab nrab itinerary deviation E (um) nyob rau hauv qhov zoo itinerary LU, EP=2*(lu/300)*v300<= c;
2. Ib qho 300mm stroke Virgin V300 (UM), V300<=
positioning precision:
(1.) Qhov tseeb ncaj qha
(2.) Axial qhov sib txawv
(3.) Lub axial rigidity ntawm cov kis tau tus mob
(4.) Thaum tshav kub kub deformation
(5.) Lub cev txav ntawm cov ntsia hlau
Rov ua dua qhov tseeb qhov tseeb: Qhov rov ua dua qhov tseeb qhov tseeb zoo li xoom.
