Cov ntsiab lus "snap nplhaib" thiab " tuav lub nplhaib" muaj kev sib raug zoo heev, but there's a hierarchical distinction:
- "Lub nplhaib tuav" yog qhov dav, qeb generic. Nws hais txog ib yam tivthaiv tsim los kom ruaj ntseg qhov chaw axially ntawm ib tug ncej los yog nyob rau hauv ib tug bore los ntawm haum rau hauv ib tug zawj.
- "Snap nplhaib" yog ib qho tshwj xeeb hom ntawm tuav lub nplhaib. It's perhaps the most common and recognizable type, characterized los ntawm nws "C" puab thiab qhov me me (pob ntseg los yog lugs) rau tshwj xeeb snap nplhaib pliers.
Here's a breakdown of the difference:
Ntiv nplhaib vs. Snap Ntiv: Qhov Distinction
Lub sij hawm Generic: Ntiv nplhaib
A tuav lub nplhaib yog lub kaus lub sij hawm rau txhua tus neeg kho tshuab fastener uas haum rau hauv lub tshuab ua zawv zawg ntawm tus ncej lossis hauv qhov tho, tsim los tiv thaiv axial txav ntawm ib qho kev sib dhos. Lawv lub hom phiaj tseem ceeb yog axial tuav.
- Lub hom phiaj: Txhawm rau tuav cov khoom (zoo li bearings, iav, pulleys, lub shims) nyob rau hauv qhov chaw raws ib axis, tiv thaiv lawv los ntawm zawv zawg tawm ntawm ib lub ncej lossis tawm ntawm lub tsev.
- Nws ua haujlwm li cas: Nws siv lub zog radial caij nplooj ntoos hlav tawm tsam phab ntsa zawj, thiab nws lub xub pwg nyom tiv thaiv cov khoom tiv thaiv los ntawm kev txav mus los ntawm nws txoj hauj lwm.
- Hom Kev Ruaj Ntseg Rings: Pawg no suav nrog ntau yam qauv tsim:
- Snap Rings (Circlips): Hom ntau tshaj plaws, nrog "pob ntseg."
- Kauv Retaining Rings: Coiled los ntawm flat wire, pob ntseg, 360-degree tiv tauj.
- E- Clips / C- Clips: Sab nraud-tsuas yog rings uas haum rau hauv grooves ntawm peb lub ntsiab lus.
- Heavy Duty Retaining Rings: Thicker versions rau siab dua thrust loads.
- Self-Locking Retaining Rings: Tej zaum yuav muaj cov hniav los yog lwm yam nta los tuav lub ncej ncaj nraim tsis muaj qhov zawj (rau cov khoom sib dua thiab kev sib dhos ib zaug).
- Push-On Retaining Rings: Zoo ib yam li kev xauv tus kheej, feem ntau siv tsis muaj groove, tso siab rau kev sib txhuam thiab cov hniav.
Analogy: Xav txog "kev tuav lub nplhaib" raws li qeb "txiv hmab txiv ntoo."
Yam tshwj xeeb: Snap Ntiv (los yog Circlip)
A snap ntiv nplhaib (kuj feem ntau hu ua a circlip, tshwj xeeb tshaj yog nyob rau hauv British English, lossis a C-ntiv nplhaib) yog ib tug dav siv thiab recognizable hom ntawm tuav lub nplhaib.
- Kev tsim kho: Feem ntau stamped los yog txiav los ntawm cov ntawv hlau (feem ntau yog caij nplooj ntoos hlav steel).
- Cov duab: Characterized los ntawm nws "C" los yog qhib lub nplhaib puab thiab, qhov tseem ceeb tshaj plaws, tus qhov me me los yog "pob ntseg" (lug) ntawm nws cov lus qhia.
- Installation / Tshem tawm: Cov pob ntseg no yog tsim los kom haum rau tshwj xeeb snap nplhaib pliers (sab hauv lossis sab nraud) uas yog siv los nthuav lossis compress lub nplhaib rau kev teeb tsa rau hauv lossis tshem tawm ntawm qhov zawj.
- Internal Snap Nplhaib: Tsim kom haum rau hauv ib lub bore, it's compressed to fit through the opening, ces nthuav mus rau hauv qhov zawj.
- Sab Nraud Snap Ring: Tsim kom haum rau ib lub ncej, it's expanded to fit over the shaft, ces snaps rau hauv qhov zawj.
- Gap: Snap rings inherently muaj qhov sib txawv ntawm lawv qhov ncig.
Analogy: Yog tias " tuav lub nplhaib" yog "txiv hmab txiv ntoo," ces "snap nplhaib" yog "apple." Kua txiv yog ib hom txiv hmab txiv ntoo.
Qhov tseem ceeb sib txawv
| Feature | Ntiv nplhaib (Generic Term) | Snap Ntiv (Hom tshwj xeeb) |
|---|---|---|
| Hierarchy | Cov qeb dav; encompasses ntau hom. | Ib hom tshwj xeeb hauv qeb tuav lub nplhaib. |
| Kev tsim kho | Nws txawv (stamped, coiled hlau, xuas nrig ntaus, lwm.). | Feem ntau stamped los ntawm cov ntawv hlau. |
| Cov duab | Ntau yam (C-puab, helical / kauv, E-clips, lwm.). | Tshwj xeeb "C" puab nrog txhais qhov sib txawv. |
| " Pob ntseg" / Lus | Tej zaum los tsis muaj lawv (E.G., spiral rings yog "earless"). | Ib txwm muaj lawv (qhov rau pliers). |
| Installation Tool | Nws txawv nyob ntawm hom (pliers, winding ntawm tes, tshwj xeeb jigs). | Yuav tsum tau tshwj xeeb snap nplhaib pliers. |
| Lub voj voog | Yuav ua tau tas mus li (E.G., kauv nplhaib) los yog gapped. | Ib txwm muaj qhov sib txawv. |
| 360° Tiv tauj | Qee hom (E.G., kauv) muab tag nrho 360 ° groove tiv tauj. | Txwv rau cov ntsiab lus sib cuag ntawm "C" puab thiab tswv yim. |
| Kev zoo nkauj / Profile | Ib txhia (E.G., kauv) muab dej yaug, earless profile. | Pob ntseg protrude, tuaj yeem pom qhov tsis txaus ntseeg lossis snag-nrhiav. |
| Kev siv RPM siab | Earless hom (kauv) zoo dua rau siab RPM vim qhov sib npaug. | Pob ntseg tuaj yeem ua rau qhov tsis sib xws ntawm kev sib hloov ceev. |

Hauv essence, tag nrho cov snap rings yog khaws cov nplhaib, tab sis tsis yog txhua lub nplhaib tuav yog snap rings. Thaum ib tug hais tias " tuav lub nplhaib," lawv tuaj yeem xa mus rau lub nplhaib snap, ib tug kauv tuav nplhaib, ib e-clip, los yog lwm daim ntawv ntawm axial retainer. Thaum ib tug neeg hais tias "snap nplhaib," lawv tab tom tham txog qhov sib txawv C-zoo li, pob ntseg-nrawm retainer uas neeg feem coob paub txog thiab uas yuav tsum tau tshwj xeeb pliers rau installation.
