《Д》型连结环容易拆卸,强度高,它用于连结浅截深联合采煤机和铇煤机给进装置的牵引机构上18×64和23×28毫米圆环焊接链的25—28米部分.连结环用高强度合金钢制成,它是用圆形轴连结起来的工作时受剪力的两个半环.为了牢固起见环的连结件用了两个钩环.技术特征标准尺寸 19×64 23×86负荷 吨力破坏负荷 48 70试验负荷 38 63尺寸 毫米
The “Д” type coupling ring is easy to disassemble and has high strength. It is used to connect 25-28 of 18 × 64 and 23 × 28mm toroidal welding chains on the traction mechanism of the shallow cutoff shearer and coal feeder M section. The coupling ring is made of high-strength alloy steel and is a half-ring half-ring subjected to work-load when connected by a circular shaft. For the sake of firmness, the ring coupling uses two hooks. Size 19 × 64 23 × 86 Load Tonnage Breaking Load 48 70 Test Load 38 63 Dimensions mm
