What is the friction principle of rubber driving belt

The friction principle of the rubber driving belt is one of the keys to its ordinary operation, related to the touch and interplay among the rubber and the steel wheel.

Contact surface and material choice

The friction principle of a rubber force belt begins with the contact between its rubber floor and the steel wheel floor. Rubber is commonly an elastic and gentle fabric with exact friction houses. In the manufacture of transmission belts, the selection of rubber desires to do not forget elements which includes its friction coefficient, wear resistance and high temperature resistance. Metal rollers generally use excessive-electricity, put on-resistant substances, together with metal or aluminum alloy, to make sure the lengthy-term strong operation of the transmission system.

Surface houses and friction coefficient

The friction precept of rubber driving belts entails the concept of friction coefficient, that is a bodily amount that represents the diploma of friction between  noticeably moving surfaces. The friction coefficient is normally divided into static friction coefficient and kinetic friction coefficient. The coefficient of static friction is the coefficient of friction while two surfaces are highly desk bound, at the same time as the coefficient of kinetic friction is the coefficient of friction when two surfaces are moving relative to each other. The rubber transmission belt wishes to preserve an appropriate friction coefficient below one-of-a-kind running conditions to make sure the reliability of the transmission effect.

Elastic deformation and contact area

When the rubber driving belt is operating, the rubber will elastically deform due to its elasticity. This deformation allows the rubber to higher adhere to the metal wheel surface, growing the touch region. A larger contact place facilitates enhance friction transmission performance. At the identical time, the pliability of rubber can also alleviate the impact and vibration of the transmission belt throughout operation, supporting to guard the stable operation of the transmission machine.

Lubrication and warmth era

A positive amount of heat is generated at some point of the friction of the rubber driving belt. In order to keep away from overheating due to friction when working at excessive pace or excessive load, some transmission structures may additionally use lubricants or cooling systems. However, in a few packages, interest desires to be paid to the impact of lubricants on rubber houses, as well as issues such as lubricant volatilization that may be brought about in excessive temperature environments.

Factors affecting friction

The friction effect of the rubber driving belt is tormented by many elements, consisting of the hardness of the rubber, surface remedy manner, shape and surface circumstance of the wheel, etc. In practical applications, those factors want to be taken into consideration comprehensively to attain the high-quality friction overall performance via reasonable design and fabric choice.
