Q:What are the main failure modes of belt drives?

The main failure modes of belt drive are skid and fatigue failure.1, with fatigue fracture:The stresses on any cross section of the band will change as the belt moves. When the stress cycle reached a certain number, that is, after running for a certain period of time, the belt appeared in the local fatigue crack delamination, and then appeared loose or even fracture, resulting in fatigue damage, loss of transmission capacity.

Q:Is the belt of the engine also called timing belt?

2, ordinary belt: ordinary, is used to pass the engine mechanical power, such as generator belt, water pump belt, booster pump belt. The power of the engine is transmitted to the corresponding components.

Q:Why is the rubber belt of the tape recorder made in China very easy to break?

There is no such manufacturer to make this. Are some small manufacturers, technical ability is poor, the material ratio is not very accurate, so there is such a phenomenon.

Q:How are belts, belts, and V belts produced? What process and equipment do they need?

This method is not absolute, but also the kind of extruder, most of China's small enterprises have extruder to do so. Because he can save a lot of money. You don't have to buy a professional molding machine. And then, it's on the molding machine. (forgot to say, the glue is compound, not natural glue, press out the thickness.). There is also a special layer of glue into the adhesive, China's three small workshops that can not care about these Continue - set it on the molding machine and then expand to a certain extent, winding the core line, also called Xian Sheng (this is the core), just like the human skeleton

Q:What are the commonly used rubber drives?

Formal classificationIt can be divided into corrugated belt, conveyor belt, pattern conveyor belt, apron conveyor belt and clapboard conveyer belt.Usage classificationDivided into: heat resistance, high temperature, burning resistance, acid, alkali, cold resistant, wear-resistant, oil resistant, flame retardant, anti tear, anti puncture.

Q:What are the factors that influence the maximum effective circumferential force transmitted by a single V belt in belt transmission?

Now, let's say the minimum initial tension, the critical friction force, the friction coefficient, the angle of the package, the relation between them. Under the influence of the minimum Flali (F_0) _min, the maximum total friction between the belt and the pulley is the frictional force that drives the belt to be slipping. It is called the critical friction force F_fc or the critical effective tension F_ec. According to the theoretical deduction, the relation between them is...

Q:An object with a relatively 4m per second speed transmission belt, acceleration is 1m/s^2, the speed belt is 1m/s, and the motion in the opposite direction, now has a fixed point in the transmission A belt, A belt with mobile A, known distance of objects into the belt where the distance is 4m, for objects time to AIt's 4*T+0.5*1*t^2=4, but it really surprised me. Why is the speed 4? The relative speed of the belt is 3?But the teacher also said that this type of questions just to see, do not look at the transmission belt objects to relative 4 speed transmission belt, is calculated to 4? But always felt very contradictory? If so, then the people on the treadmill but practical and relatively static movement in motion

The object and the drive belt is back to the line, the sports department is actually the muzzle velocity of uniformly accelerated motion, S = V + a - t / integrant.

Q:Some of the machines use belts and some use the transmission chain. They want to ask what conditions they use

The flat belt can mainly deliver the function of the goods and has the function of conveying; the synchronous belt transmits the power more accurately, and is suitable for the precise transmission when the space position is large

Q:Drive a women's motorcycle is bad, can be repaired or replaced, how much is the price

Sure to change, and the belt may be gone, the general price between 25--50

Q:Do I need to add grease to the V belt or belt?

No, the belt is part of the transmission that is designed to transmit power,
