Dab tsi yog auxiliary fasteners?

"Fasteners" yog ib lo lus dav dav rau cov khoom siv kho tshuab siv kom ruaj ntseg koom nrog ob lossis ntau qhov chaw rau hauv ib lub rooj sib txoos. Txij li feem ntau cov fasteners yog standardized, lawv feem ntau hu ua "standard parts". Standard fasteners feem ntau yog categorized rau hauv 12 pawg hauv qab no:

1. Bolts: muaj ib lub taub hau thiab ib tug threaded shank; used in conjunction with a nut to fasten two parts with through-holes, forming a detachable connection (eg, high-strength bolt assemblies used in steel structures).

2. Studs: Tsis muaj lub taub hau thiab muaj cov xov sab nraud ntawm ob qho kawg; ib kawg yog ntsia hlau rau hauv ib feem, thaum lwm qhov hla dhau los ntawm - qhov kom tau txais cov txiv ntoo. Siv nyob rau hauv daim ntawv thov yuav tsum tau compact tsim los yog nquag disassembly.

3. Screws: Muaj lub taub hau thiab lub shank; feem ntau screwed ncaj qha mus rau hauv ib tug threaded qhov nyob rau hauv ib feem yam tsis tas yuav tsum tau ib tug txiv ntseej. Muab faib los ntawm kev ua haujlwm rau hauv lub tshuab ntsia hlau, teeb tsa cov ntsia hlau, thiab cov ntsia hlau tshwj xeeb (xws li lub qhov muag bolts).

4. Cov txiv ntseej: Feature ib lub qhov threaded thiab feem ntau zoo li lub tiaj hexagonal prism; siv nrog bolts, studs, lossis tshuab screws kom ruaj ntseg kev sib txuas.

5. Tus kheej-tapping Screws: Zoo ib yam li tshuab screws tab sis feature tshwj xeeb rau tus kheej-tapping threads; lawv tuaj yeem ntsia tau ncaj qha mus rau hauv lub pre-drilled qhov los txiav lawv tus kheej threads. Feem ntau siv los koom nrog cov khoom siv hlau nyias.

6. Ntoo Screws: Zoo ib yam li tshuab screws tab sis feature tshwj xeeb ntoo threads; lawv tuaj yeem ntsia tau ncaj qha rau hauv cov khoom ntoo kom ceev cov hlau los yog tsis yog- hlau qhov chaw rau ntoo.

7. Cov tshuab ntxhua khaub ncaws: Muab tso rau ntawm lub fastener thiab cov khoom ua haujlwm kom muaj kev sib cuag, txo qhov siab, thiab tiv thaiv qhov chaw ntawm qhov chaw; caij nplooj ntoos hlav washers kuj pab tiv thaiv kom loosening.

8. Retaining Rings: Muab tso rau hauv grooves ntawm shafts los yog nyob rau hauv lub bores ntawm machinery thiab khoom siv los tiv thaiv lub axial txav ntawm qhov chaw mounted ntawm lub ncej los yog nyob rau hauv lub bore.

9. Pins: Feem ntau yog siv rau qhov chaw, tab sis kuj rau kev sib txuas, xauv, los yog ua raws li cov khoom siv overload shear hauv kev nyab xeeb; Cov hom muaj xws li cylindrical pins, tapered pins, thiab cotter pins.

10. Rivets (Rivets): Muaj lub taub hau thiab lub shank; lawv koom nrog cov txheej txheem los ntawm cov txheej txheem riveting, tsim kom muaj kev sib txuas mus tas li (tsis yog-detachable).

11. Kev sib dhos thiab kev sib txuas ua ke: Hais txog cov fasteners muab los ua ib chav ua ke-piv txwv li, screws, bolts, los yog tus kheej -tapping screws muab ua ke nrog washers.

12. Lwm yam: Feem ntau suav nrog cov khoom xws li weld studs.

Tsis tas li ntawd, fasteners tuaj yeem raug cais raws li tus qauv lossis tsis yog- tus qauv raws li seb lawv ua raws li cov qauv tsim; Cov khoom siv xws li carbon steel, stainless hlau, thiab tooj liab. Lawv tuaj nyob rau hauv ib tug loj array ntawm specifications, nrog tag nrho cov naj npawb ntawm ntau yam thoob ntiaj teb no ntau tshaj 500,000.
