ZOTSWATSA NTCHITO

Mphete inagawanika pamalo amodzi ndikupindika mu mawonekedwe a helical. Izi zimapangitsa kuti makina ochapira agwiritse ntchito mphamvu ya masika pakati pa mutu wa fastener ndi gawo lapansi, zomwe zimasunga makina ochapira molimba pa gawo lapansi ndi ulusi wa bawuti molimbana ndi nati kapena ulusi wa gawo lapansi, kupangitsa kukangana kwambiri ndi kukana kuzungulira. Miyezo yovomerezeka ndi ASME B18.21.1, KUCHOKERA 127 B, ndi United States Military Standard NASM 35338 (yomwe kale inali MS 35338 ndi AN-935).

 

Makina ochapira masika ndi helix ya kumanzere ndipo amalola ulusi kumangika kumanja kokha, mwachitsanzo, kuwongolera kozungulira. Pamene kutembenuka kwa dzanja lamanzere kukugwiritsidwa ntchito, m'mphepete mwake mumaluma pansi pa bawuti kapena nati ndi gawo lomwe latsekeredwa, motero kukana kutembenuka. Chifukwa chake, ochapira masika sagwira ntchito pa ulusi wakumanzere ndi malo olimba. Komanso, sayenera kugwiritsidwa ntchito pamodzi ndi chotsuka chophwanyika pansi pa makina ochapira kasupe, chifukwa izi zimalekanitsa kasupe wa kasupe kuluma mu chigawo chomwe chidzakana kutembenuka.

 

Ubwino wa makina ochapira masika ali mu mawonekedwe a trapezoidal a washer. Ikakanikizidwa ku katundu pafupi ndi mphamvu yaumboni wa bawuti, imapindika ndikuphwanyidwa. Izi zimachepetsa kuthamanga kwa kasupe kwa mgwirizano wa bolt womwe umalola kuti ukhalebe ndi mphamvu zambiri pansi pa milingo yogwedezeka yofanana. Izi zimalepheretsa kumasuka.

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).
