Ama-washers entwasahlobo

Incazelo emfushane:

Indandatho ihlukaniswe ngesinye isikhathi futhi yagoqeka yaba yindilinga. Lokhu kubangela ukuthi i-washer isebenzise amandla entwasahlobo phakathi kwekhanda le-fastener ne-substrate, egcina i-washer kanzima ngokumelene ne-substrate nentambo ye-bolt kanzima ngokumelene ne-nut noma i-substrate intambo, okwenza ukungqubuzana okwengeziwe nokumelana nokuzungeza. Izindinganiso ezisebenzayo yi-ASME B18.21.1, i-DIN 127 B, ne-United States Military Standard NASM 35338 (phambilini eyi-MS 35338 ne-AN-935).

Incazelo

Indandatho ihlukaniswe ngesinye isikhathi futhi yagoqeka yaba yindilinga. Lokhu kubangela ukuthi i-washer isebenzise amandla entwasahlobo phakathi kwekhanda le-fastener ne-substrate, egcina i-washer kanzima ngokumelene ne-substrate nentambo ye-bolt kanzima ngokumelene ne-nut noma i-substrate intambo, okwenza ukungqubuzana okwengeziwe nokumelana nokuzungeza. Izindinganiso ezisebenzayo yi-ASME B18.21.1, i-DIN 127 B, ne-United States Military Standard NASM 35338 (phambilini eyi-MS 35338 ne-AN-935).

Ama-washer entwasahlobo ayi-helix yesandla sangakwesobunxele futhi avumela intambo ukuthi iqiniswe ohlangothini lwesokunene kuphela, isb ohlangothini lwewashi. Lapho kusetshenziswa ukunyakaza kwesandla sokunxele, umphetho ophakanyisiwe uluma ungene ngaphansi kwebhawodi noma kwenadi nengxenye eboshelwe kuyo, ngaleyo ndlela umelane nokujika. Ngakho-ke, ama-washer entwasahlobo awasebenzi ezintanjeni zesandla sobunxele nasezindaweni ezilukhuni. Futhi, akufanele zisetshenziswe ngokuhlanganyela ne-washer eyisicaba ngaphansi kwe-washer yasentwasahlobo, njengoba lokhu kwehlukanisa isher wasentwasahlobo ekulungeni entweni ezomelana nokujika.

Inzuzo yama-washer yokukhiya entwasahlobo ilele esimweni se-trapezoidal ye-washer. Lapho icindezelwe ukulayisha eduze namandla obufakazi bomshudo, izosonta futhi isicabale. Lokhu kunciphisa izinga lentwasahlobo lejoyinti eliboshiwe elilivumela ukuthi ligcine amandla amaningi ngaphansi kwamazinga afanayo okudlidliza. Lokhu kuvimbela ukukhululeka.

Izicelo

Isher washer ivimbela amantongomane namabhawodi ekuphendukeni, ekushibilikeni nasekuphumeni ngenxa yokudlidliza ne-torque. Ama-washer entwasahlobo ahlukile enza lo msebenzi ngezindlela ezihluke kancane, kepha umqondo oyisisekelo ukubamba inothi nebhawodi endaweni yalo. Amanye ama-washer entwasahlobo afeza lo msebenzi ngokuluma ezintweni eziyisisekelo (umshudo) ne-nut eneziphetho zazo.

Ama-washer entwasahlobo asetshenziswa kakhulu kuzinhlelo zokusebenza ezibandakanya ukudlidlizela kanye nokushelela okungenzeka kokuqina. Izimboni ezivame ukusebenzisa ama-washer entwasahlobo zihlobene nokuhamba (okwezimoto, izindiza, olwandle). Ama-washer asentwasahlobo angasetshenziswa futhi ezintweni zasendlini ezifana nezinto zokuphatha umoya nezokuwasha izingubo (imishini yokuwasha).
