Gear lubricant related questions

1. What is the principle of gear lubrication?
(1) Determine categories according to the particularity of the application, such as open gear lubricants, closed gear lubricants, worm gear lubricants, etc.
(2) Determine the grade according to the contact stress of the tooth surface, such as anti-oxidation rust gear lubricant, heavy duty industrial gear lubricant, etc.
(3) Determine the viscosity selection lubricant according to factors such as the gear line speed and the use temperature.
2. The main form of gear failure and the effect of lubrication on gear failure
The main forms of gear failure are broken teeth, wear, pitting, and gluing. The failure of the gear pair at work is directly related to the traits of the transmitted motion and power. Lubrication is an indispensable part of the surface science of studying the relative motion and interaction of gears.
3. Why can't open gear lubricants be replaced by closed gear lubricants?
Over the years, in the cement, metallurgy, mining and other industries, open gear devices are commonly used in large rotating equipment, such as dryers, grinders, mine shovel, etc., but the lubrication of their equipment is not enough, leading to accidents. happens sometimes. China has developed specifications for ordinary open gear lubricants, and extreme pressure type open gear lubricants (L-CKJ) are also available. Users can select the corresponding lubricants according to their needs. Some people used closed industrial gear lubricating oil instead of open gear lubricating oil. As a result, not only oil leakage, lubrication failure, but also serious splashing of oil, environmental pollution, and waste, so the lubricant can not be used for a long time.
