A locknut, makwaara dị ka a mkpọchi nut, kpochidoro nut, onwe-kpochidoro nut, na-emeri torque nut, ikwesi nutor agbanwe stop nut, bụ a nut na-eguzogide echikwapụ n'okpuru vibrations na torque. Na-agbanwe stop mkpụrụ na-enwe mmeri torque mkpụrụ nke ụdị ebe akụkụ ụfọdụ nke aku deforms elastically inye a kpochidoro action.The mbụ ụdị eji eriri kama naịlọn na echepụta na 1931.

Atọ uru nke mkpọchi mkpụrụ:

First, elu mgbochi vibration arụmọrụ: Mgbe na eri na-tightened, na eri nke ịghasa crest nke bolt tightly abatakwa 30 Celsius nkpirikpi-ekara ná mkpọda nke aku na clamped. The axis bụ na ihe gụnyere n'akuku nke 60 Celsius, kama gụnyere n'akuku nke 30 Celsius. Ya mere, ndị nkịtị ike site mgbe mkpọchi nut na-tightened bụ nnọọ ukwuu karịa nke a ọkọlọtọ nut, na ya nwere oké ike iji gbochie looseness na vibration.

Second, wear resistance and shear resistance are strong: the 30 ° bevel of the thread of the nut thread can evenly distribute the nut's locking force on the threads of all the teeth. Because the pressing force on the thread surface of each tooth is evenly distributed, The nut can better solve the problems of thread wear and shear deformation.

Nke atọ, ezi re-eji arụmọrụ: A ọnụ ọgụgụ buru ibu nke iji na-egosi na kpochidoro ike nke mkpọchi nut na-adịghị ebelata mgbe ugboro ugboro ugboro ugboro tightening na disassembly, na mbụ kpochidoro mmetụta pụrụ nọgidere na-enwe.
