Screws kubwa za kubeba mzigo mkubwa

Utangulizi wa muundo wa bidhaa na utengenezaji:

Urefu na mzigo mzito daima imekuwa shida katika utengenezaji wa screws kubwa na nzito za mpira. Mfululizo huu wa bidhaa umeshinda teknolojia ya kubuni, matibabu ya joto, upatanishi, njia za mbio kutengeneza usindikaji na kugundua nguvu. Inayo muundo wa kitanzi cha mzunguko wa mpira wa kiwango kikubwa, kiwango cha juu cha nguvu cha bidhaa ni tani 126, na kiwango cha juu kilichokadiriwa kuwa tani 595. KGG sasa imetumia safu ya vifaa kama vile lathe kubwa ya mita 10, mashine ya kuzungusha vifaa vya mita 10, mashine kubwa ya kusaga mita 10, zana ya mashine ya kuzima ya mita 10 ya kati, mashine kubwa ya kunyoosha mita 10, na chombo cha kupima kiharusi cha mita 10. Chukua risasi katika kuanzisha safu ya kwanza ya uzalishaji wa mpira wa miguu ya mita 10 nchini China, ambayo chombo cha kupima cha laser cha laser cha mita 10 kimepitisha hesabu ya Taasisi ya Jiangsu ya Metrology na imetumika, kutatua shida ya screw ya mpira wa mita 10. Teknolojia muhimu katika mchakato wa kugundua nguvu wa jozi ya screw.

Kumbuka:

1) K ni thamani ya hesabu ya nadharia wakati nguvu ya upakiaji F ni 0.1ca na mzigo wa axial F ni 0.3c;

2) Wakati mzigo wa axial f sio sawa na 0.3c, k katika formula ni thamani ya ugumu kwenye meza

3) Inafaa kwa matumizi katika hali ya joto ya juu
