skrubu kubwa za Mpira wa Kupakia Mzito
Utangulizi wa muundo na utengenezaji wa bidhaa:
Urefu na mzigo mkubwa daima imekuwa tatizo muhimu katika utengenezaji wa screws kubwa na nzito-wajibu wa mpira. Msururu huu wa bidhaa umeshinda teknolojia ya muundo, matibabu ya joto, upatanishi, usindikaji wa kutengeneza barabara na ugunduzi wa nguvu. Inayo muundo wa muundo wa kitanzi cha mzunguko wa mpira wa kipenyo cha njia nyingi, kiwango cha juu cha mzigo wa nguvu wa bidhaa ni tani 126, na kiwango cha juu cha mzigo wa tuli ni tani 595. KGG sasa imetumia mfululizo wa vifaa kama vile lathe kubwa ya mita 10, mashine ya kusaga ya vifaa vya mita 10, mashine kubwa ya kusaga yenye urefu wa mita 10, zana ya kati ya mita 10 ya kuzima masafa ya kati, mita 10. mashine kubwa ya kunyoosha, na kifaa cha kupima skrubu ya leza ya mita 10. Chukua nafasi ya kwanza katika kuanzisha njia ya kwanza ya kuzalisha skrubu za mpira wa mita 10 nchini China, ambayo chombo cha kupima hitilafu ya kusafiri ya skrubu ya mita 10 imepitisha urekebishaji wa Taasisi ya Jiangsu ya Metrology na imeanza kutumika, kutatua tatizo la screw moja ya mpira wa mita 10. Teknolojia muhimu katika mchakato wa ugunduzi wa nguvu wa jozi ya skrubu.

Kumbuka:
1) K ni thamani ya hesabu ya kinadharia wakati nguvu ya upakiaji mapema 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 fomula ni dhamana ya ugumu kwenye jedwali.
3) Inafaa kwa matumizi katika hali ya joto la juu
