The V -- belt Drive system of long lifespan, so as to meet the market demand, tool has great significance.But common V-belt is using
Shi Rongyi skids, and not only reducing transmission efficiency can also cause the abrasion of V-belt.There is patent to propose three for these problems
Angle is improved the method for coefficient of friction and prevents belt slippage with both sides by increasing side projection, although these utility models are increasing
Also increasing the frictional force of radial frictional force, i.e. V-belt when belt wheel is entered and left while big circumference frictional force also increases
, not only consumed energy, and heat and the abrasion of V-belt are accelerated, the projection of side is also easily worn away.
Equlvalent coefficient of friction reflects the integration capability of belt transmission, in the case of the more big identical tensile force of equlvalent coefficient of friction
The power of transmission is bigger.According to V-belt equlvalent coefficient of friction computing formula
μ ' in formula --- equlvalent coefficient of friction
