VIOSHA VYA SPRING

Pete iligawanyika kwa hatua moja na kuinama kwa sura ya helical. Hii husababisha washer kutumia nguvu ya spring kati ya kichwa cha kufunga na substrate, ambayo hudumisha washer kwa nguvu dhidi ya substrate na thread ya bolt kwa nguvu dhidi ya nut au substrate thread, na kujenga msuguano zaidi na upinzani dhidi ya mzunguko. Viwango vinavyotumika ni ASME B18.21.1, KUTOKA 127 B, na Kiwango cha Kijeshi cha Marekani NASM 35338 (zamani MS 35338 na AN-935).

 

Washers wa spring ni helix ya mkono wa kushoto na kuruhusu thread kuimarishwa katika mwelekeo wa mkono wa kulia tu, yaani mwelekeo wa saa. Wakati mwendo wa kugeuza mkono wa kushoto unatumiwa, makali yaliyoinuliwa huuma kwenye sehemu ya chini ya bolt au nut na sehemu ambayo imefungwa, hivyo kupinga kugeuka. Kwa hiyo, washers wa spring hawana ufanisi kwenye nyuzi za mkono wa kushoto na nyuso ngumu. Pia, hazipaswi kutumiwa kwa kushirikiana na washer wa gorofa chini ya washer wa spring, kwa kuwa hii hutenganisha washer wa spring kutoka kwa kuuma kwenye sehemu ambayo itapinga kugeuka.

 

Faida ya washers wa kufuli ya spring iko katika sura ya trapezoidal ya washer. Inapobanwa kwa mizigo karibu na uthabiti wa uthibitisho wa bolt, itasokota na kubapa. Hii inapunguza kasi ya chemchemi ya kiungo kilichofungwa ambayo inaruhusu kudumisha nguvu zaidi chini ya viwango sawa vya mtetemo. Hii inazuia kulegea.

The spring washer prevents nuts and bolts from turning, slipping and coming loose because of vibration and torque. Different spring washers perform this function in slightly different ways, but the basic concept is to hold the nut and bolt in place. Some spring washers achieve this function by biting into the base material (bolt) and the nut with their ends.

 

Spring washers are commonly used in applications involving vibration and possible slippage of fasteners. Industries that commonly use spring washers are transportation related (automotive, aircraft, marine). Spring washers may also be used in household appliances such as air handlers and clothes washers (washing machines).
