What'sTorque什么是转矩

What is torqueandtension?什么是扭矩和紧张？

Torque = T转矩=Ť
Force = F**=F的
Torque = Force by TurningorTwisting.转矩=**转向或扭曲。
Tension = Power by CreatingofStraight-Pull.张力=国通过建立直拉。
(but, differs fromTorque)（但不同于转矩）
so that: Torque is usedforcreating Tension.这样：扭矩是用于制造紧张局势。

How to MakeTorqueEvaluation如何使扭矩评价

Torque (T) = Force (F) xDistance(L)转矩（吨） =力（女） ×距离（长）
so that:这样：
T1 = F1 x L1 = 10 lbs x 2 ft =20ft·lbs表＃ t1 = F1的x母语=十磅× 2英尺= 20英尺磅
T2 = F2 x L2 = 20 lbs x 1 ft =20ft·lbs时刻= F2代x的L2 =二○磅× 1英尺= 20英尺磅
T1 = T2表＃ t1 =时刻

Why IsTorqueNecessary?为什么转矩有必要吗？

(A) In case ofthreadedobjects: Example: Bolts ofcar-wheel（ a）在案件线索物体：例如：螺栓汽车轮

• Lightly tightened (lackoftorque)轻轻收紧（缺乏扭矩） Bolts will be loosened gradually and car accident might occur.螺栓将逐步放宽，可能会发生车祸。
• Strongly tightened(overtorque)大力加强（超过扭矩） Bolts are tightened just before breaking point, so bolts might be suddenly broken, due to highter tension caused by temperature or shocks.螺栓是收紧突破点之前，所以螺栓可能突然破裂，由于高于造成的紧张局势温度或冲击。
• Properly tightened(suitabletorque)适当收紧（适合扭矩） OK.确定。
• （ b）在案件unthreaded物体：例如：频道的电视集
  • Lightly tightened (lackoftorque)轻轻收紧（缺乏扭矩） Easy to turn/ bad contact / unstable picture.方便地将/坏接触/不稳定的图片。
  • Strongly tightened(overtorque)大力加强（超过扭矩） Difficult to turn / large friction / short life, difficult to use.很难打开/大摩/寿命短，难以利用。
  • Properly tightened(suitabletorque)适当收紧（适合扭矩） OK.确定。

   

  What IsSuitableTorque什么适合转矩

  (A) When the joint doesnotreceive external force orvibration（甲）当关节没有收到外部武力或振动
  Q = (0.5 to 0.7) P为Q =（0.5至0.7 ）芘
  (B) When the jointreceivesexternal force or vibration（乙）当联合接收外部武力或振动
  Q = (0.5 to 0.6) P为Q =（0.5至0.6 ）芘
  Note: Q = SuitableTorque  P = Breaking Torque注：为Q =适合扭矩P值突破转矩

   

  BoltTighteningMethod螺栓拧紧方法

  There are three ways to makesurethat tightening is correct.有三种方式，以确保加息是正确的。

  (A) Torquecontrolmethod（一）转矩控制方法
  Using hand torque tool (wrenchordriver), or power operated torque tool (screwdriver ornutrunner) totighten screws, nuts andbolts.用手提扭矩工具（扳手或驱动程序），或动力操作扭矩工具（螺丝刀或nutrunner）收紧螺丝，螺母和螺栓。
  (B)Part-turnmethod （b）**部分转法
  Bolts are tightened untiljointsurfaces are in closecontact.螺栓是收紧，直至联合表面有密切接触。At thatpoint, just before solid tightening starts, nut and protruding boltthreads are marked to show their relativepositions.在这一点，就在坚实的紧缩开始，螺母，螺栓螺纹凸起标记，以表明其相对位置。Then, correct tightening is completed by turning the nut a half or 3/4 turn.那么，正确的紧缩完成转动螺母半或3月4日关闭。
  (C) Boltelongationmeasuringmethod（丙）螺栓伸长率测量方法
  When bolts are tightened atthesame time, the elongation of the boltsaremeasured.当螺栓被收紧的同时，延长螺栓测量。
