Yintoni injongo yeeWasher zaseNtwasahlobo?
Iiwasha zaseNtwasahlobo vs iiwasha eziFlethi
Kwiinkqubo ze-fastener, i-washers zizinto ezincinci kodwa ezibalulekileyo ezenzelwe ukuhambisa umthwalo, ukukhusela ukukhulula, okanye ukukhusela umphezulu. Phakathi kwabo, i-spring washers kunye ne-flat washers zisebenza indima eyahlukileyo. Iiwasha ezisicaba, ezikwabizwa ngokuba ziiwasha ezingenanto, zilula, iidiski ezisicaba ezinomngxuma osembindini. Injongo yabo ephambili kukusasaza ngokulinganayo amandla okubamba phantsi kwebholithi okanye i-nut, ukunciphisa ukukhuhlana ngexesha lokuqinisa, kunye nokukhusela iindawo ezithambileyo emonakalweni.Iiwasha zasentwasahlobo, kwelinye icala, zenziwe ngobunjineli obufana ne-helical okanye i-wave-like shape ukuba isebenze njengomthombo ocinezelekayo. Umsebenzi wabo ophambili kukugcina uxinzelelo kumalungu adityanisiweyo, ukuhlawulela ukukhulula okubangelwa kukungcangcazela okanye ukwandiswa kwe-thermal/contraction. Ngelixa iiwasha ezisicaba zijolise ekusasazeni umthwalo kunye nokukhuselwa komphezulu, iiwasha zasentwasahlobo zijongana nemingeni eguqukayo efana nokungcangcazela kunye nokuhamba.
Yintoni injongo yeeWasher zaseNtwasahlobo?
Iiwasha zasentwasahlobo zizizisombululo zokuqina eziguquguqukayo ezenzelwe ukuchasana nokukhulula kwiindawo ezinoxinzelelo oluphezulu. Xa zixinzelelwe phakathi kwe-nut / bolt kunye nomphezulu, i-deformation yabo ye-elastic yenza i-axial force eqhubekayo. Olu xinzelelo "luvala" umdibaniso ngokuchasana namandla ajikelezayo okubangelwa kukungcangcazela, ukothuka, okanye ukuguquguquka kobushushu. Iindidi eziqhelekileyo zibandakanya i-helical spring washers (i-coil-shaped) kunye ne-wash washers (amakhonkco e-sinusoidal). Ii washers ze-helical zisetyenziswa ngokubanzi koomatshini kunye nezicelo zeemoto, ngelixa iiwashi zamaza zihambelana nomthwalo ophantsi, iindibano ezixinzelelekileyo. Ngokucacileyo, iiwasha zasentwasahlobo azikho izilungiso zendalo yonke; ukuqiniswa kakhulu kunokubenza mcaba, kungakhathaleli umphumo wabo wasentwasahlobo, kwaye baqhube kakubi kwiimeko ezimileyo okanye eziphantsi. Ukukhethwa kwezinto ezifanelekileyo (umzekelo, intsimbi engatyiwayo, intsimbi yekhabhoni) nako kubalulekile ukungqamanisa neemeko zokusingqongileyo ezifana nomhlwa okanye ubushushu obugqithisileyo.
Ukudityaniswa kweWasher eFlethi kunye nezasentwasahlobo
Kwiinkqubo ezininzi zemizi-mveliso, ukudibanisa i-flat kunye ne-spring washers kwandisa ingqibelelo edibeneyo. Iwasha eflethi ibekwe ngokuthe ngqo kwindawo yokusebenza ukuze isasaze ngokulinganayo ibholiti/i-nut yamandla okubamba, ukuthintela ukonakala komphezulu kunye nokunciphisa uxinzelelo loxinzelelo. Iwasha yasentwasahlobo ke ngoko ibekwe phakathi kwewasha esicaba kunye nesiqhoboshi (intongomane okanye intloko yebholiti). Olu lungelelwaniso luvumela iwasha yasentwasahlobo ukuba isebenzise i-axial tension yayo ngelixa iwasha eflethi ikhusela izixhobo zokusebenza kunye newasha yasentwasahlobo ukusuka kuguquko okanye ukunxiba. Ngokomzekelo, kwiinkqubo zokuxhoma iimoto okanye oomatshini abanzima, oku kubhanqa kuqinisekisa ukuxhathisa ukungcangcazela ngelixa ugcina ukuhanjiswa komthwalo. Iinjineli kufuneka zilandele umyalelo wofakelo olufanelekileyo: iiwasha zasentwasahlobo zilahlekelwa ukusebenza kakuhle xa zibekwe ngokungalunganga okanye zixinaniswe kakhulu. Ukongeza, iikhompawundi zokutshixa intambo zinokongeza olu seto kwiindawo zokungcangcazela.
