- Q:The difference between a ratchet wrench and a torque wrench
- Torque wrench. - also called torque wrench or torque wrench, torque force and distance is the product of the need to control the torque exerted on the fastening screw bolt and nut threaded fasteners, to ensure that the thread fastening torque is too large and does not damage due to threads, so use the torque wrench to operate. The first set a torque limit when the applied torque reaches the set value, the wrench will be issued a "Kata" sound or a wrench bend at the joint point of this representative has not the fastening force.
- Q:What is the torque tolerance of a wrench?
- Torque (Torque, also known as torque) in physics is a special moment, is the product of the force and force arm, the international unit is Nm nm, also can see the KGM lb-ft, such as G=mg, torque, when g=9.8 1kg, the weight is 9.8N, so 1kgm= 9.8Nm, while the pound feet lb-ft is the imperial torque unit, 1lb=0.4536kg; 1ft=0.3048m, 1lb-ft=0.13826kgm can be calculated. In everyday expression, torque is often referred to as torque (in physics, these are 2 different concepts). For example, the torque of the 8 generation Civic 1.8 is 173.5Nm@4300rpm, which means that the output torque of the engine at 4300 revolutions per minute is 173.5Nm. How can the force of 173.5N drive 1 tons of cars? In fact, the engine torque will be magnified (at the same time reduce the speed), this will depend on the transmission, the final transmission and the tire. The release of the first engine torque through the transmission "adjustable" to end transmission torque amplification (for further amplification in the year-end party) (at the same time, to further reduce the speed) finally released the driving force of tire. If a car 1 speed gear ratio (the number of teeth of the gear ratio, is the essence of gear radius ratio) is 3, year-end party 4, tire radius of 0.3 meters, the original torque is 200Nm, the last in the axle torque to 200 x 3 x 4=2400Nm, divided by the tire radius of 0.3 meters, friction the tire and the ground part is 2400Nm/0.3m=8000N, that is the driving force of 800 kg, which is enough to drive a car.
- Q:How to distinguish movable spanner and adjustable spanner?
- Different name only, layman called "active wrench", the expert is called "adjustable wrench"
- Q:Generally use the adjustable wrench how many inches bike repaired?
- 12 inch adjustable wrench can.Ring wrenches and open spanners are commonly used in bicycle maintenance.Screws are usually No. 10, No. 12, No. 13, No. 14, No. 15, No. 17, No. 8 wrench.Fork nut axis bowl screw, with 12 inch barrel wrench completely enough.
- Q:What problems do sleeve wrenches use?
- Caution with torque wrench:1., pay attention to waterproof, mud, sand and other debris into the wrench handle, torque wrench is strictly prohibited when the use of hammer.2. when using the wrench head to be leveled, force should be uniform, not too hard or exert impact force.3. when the torque wrench issued a "click" sound, to immediately stop the wrench, wrench force to prevent damage to the part of the 4 set to zero in the wrench is strictly prohibited to use, because in this state after no sound signal, easy to overload damage wrenchWhen the 5. wrench is not suitable for a long time, the wrench scale shall be set on the zero position so as to avoid the fatigue failure of the force measuring element.6. during the process of use, if the wrench does not sound, the signal should be stopped immediately for maintenance. After maintenance, the wrench needs to be calibrated and can be used before calibration.
- Q:How do you adjust the pressure on the pressure gauge and the tightening torque of the bolt on the hydraulic wrench?
- According to the type and torque range of the wrench, the pressure set by each model is different.There are corresponding torque and pressure control tables.
- Q:How many types of torque wrenches are there? How do you distinguish them?
- Then the manual torque wrench, in the current Chinese, or more commonly used, I use this brand a strong SVETRUCK (I learned today, I doubt today is also a similar problem), they are: preset type torque wrench, digital type torque wrench, torque dial wrench, constant torque wrench these categories.
- Q:What is a stall type hydraulic pulse pneumatic tool?
- Stall type hydraulic pulse wrench is different from the percussive start wrench, percussive pneumatic wrench, pneumatic motor driven hammer strike block rotation, easy to cause harm to the bolts, the torque fluctuation is relatively large, but not easy to set twisting speed.The stall type wrench is relatively accurate through constant rotation and constant torque.
- Q:Inside the six angle wrench, if required to black appearance, generally do what processing, wear and rust prevention effect will be better? How about the cost?
- In addition, the plating black nickel or black chromium can also achieve your appearance and wear-resistant effect, but the cost is very high, I have not seen such products.
- Q:Which kind of material is good for inner six angle spanner?
- In the name of "wrench" means "twisting" action, it embodies the inner six angle wrench and other common tools (such as: slotted screwdriver and screwdriver) between the most important difference, it exerts a force on the screw torque, greatly reduces the user's hard strength. It can be said that in the modern furniture industry involved in the installation of tools, the six angle wrench is not the most commonly used, but it is the best use.
