The difference between Hawa chain and ordinary chain：

（1) The speed of the toothed chain is 16 meters per second, and the speed of the Hawa chain is 30-50 meters per second

（2) Small error: Ordinary chains use single axis circular shafts, while Haval chains use double axis flat shafts

A.Having good qualitiesgoodThe permeability of
For chains, lubricating the rollers and sprockets is relatively easy, but lubricating the chain shaft and sleeve is more difficult. Due to the very small gap between the shaft and the sleeve, and the fact that it is completely open environmental conditions. If lubricating oil does not have good permeability, it cannot penetrate into the interior of the shaft and shaft sleeve, and therefore cannot lubricate the shaft and shaft sleeve.
B. There must begoodGood adhesion
During the operation of the chain, the lubricating oil will be thrown off due to the high-speed effect. At low speeds, lubricating oil will drip due to the force of gravity. All of these not only pollute the environment and products, but also cause a lot of waste. Therefore, it is required that lubricating oil has good adhesion and can firmly adhere to the friction surface without falling off due to various effects.
C. HavinggoodLubrication performance
One of the functions of lubricating oil is lubrication, but chains require higher lubrication performance due to different effects during operation, especially for chains under heavy loads and impact conditions, which require higher extreme pressure and anti-wear properties. Therefore, most chain lubricants pay great attention to this requirement.
D. Has outstanding oxidation stability
Usually, chain drives work in exposed environments, so chain lubricants are required to havegoodThe oxidative stability.
E. HavingcompareSmall evaporation loss rate
F. Has good resistance to external forces
G. Has the characteristic of being less susceptible to pollution
H. Has the smallest tendency to accumulate carbon

The above are the basic requirements for lubricants in chain drives, and of course, there are many other requirements that may vary in emphasis depending on the scope of use, environment, equipment requirements, and other factors of the transmission chain.
