static stress 静态应力 reversed stress 反向应力 repeated stress 重复性应力 axles 短轴 Spring A spring is a load-sensitive, energy-storing device, the chief characteristics of which are an ability to tolerate large deflections without failure and to recover its initial size and shape when loads are removed. energy-storing 蓄能的 tolerate 承受 deflections 变形 recover 恢复 Although most springs are mechanical and derive their effectiveness from the flexibility inherent in metallic elements, hydraulic springs and air springs are also obtainable. derive their effectiveness from the flexibility inherent in metallic elements 利用金属部件本身所固有的弹性 Springs are used for a variety of purposes, such as supplying the motive power in clocks and watches, cushioning transport vehicles, measuring weights, restraining machine elements, mitigating the transmission of periodic disturbing forces motive power 原动力 restraining 约束 mitigating 减轻 from unbalanced rotating machines to the supporting structure, and providing shock protection for delicate instruments during shipment. delicate 精密的 Ｐart　２Couplings, Clutches, Shafts and Springs 1. coupling n.联轴节 2.?????? clutch n.离合器 3.?????? shaft n.轴 4.?????? spring n.弹簧 5.?????? line shaft 天轴 6.?????? propeller n.推进器 7.?????? rigid coupling 刚性联接 8.?????? mate v.匹配 9.?flange n. 法兰、凸缘 10.?? key n.键 11.?? hub n.轴毂 12.?? bolt v. 螺栓联接 13.?? alignment n.对中 14.?? rabbet joint n. 槽舌接合, 嵌接 15. electric motor 电动机 16. gearbox n. 齿轮箱 17. flexible coupling 弹性联接 18. misalignment n. 偏移 19. deflect v.
