Grease lubrication is a commonly used lubrication method for ring gears. Grease is applied regularly to the friction surface of the ring gear through a manual or automatic lubrication system. This method is suitable for low-speed, low-load ring gears and has the advantages of easy operation and low cost. However, it should be noted that grease may deteriorate or run off under high temperature or high speed conditions, thus affecting the lubrication effect.
Oil bath lubrication is to immerse the ring gear in a lubricating oil pool and use the rotation of the gear to bring the lubricating oil to the friction surface. This method is suitable for medium-speed, medium-load ring gears and has good heat dissipation and lubrication effects. However, it should be noted that the oil level should be controlled within an appropriate range. Too high or too low may affect the lubrication performance.
Oil spray lubrication uses a nozzle to spray pressurized oil onto the friction surface of the ring gear to form an oil film for lubrication. This method is suitable for high-speed, high-load ring gears and can effectively reduce friction and wear. Oil injection lubrication systems are usually more complicated, but the lubrication effect is significant.
Oil mist lubrication is to mix lubricating oil with compressed air to form oil mist, which is then sprayed onto the friction surface of the ring gear. This method has the dual functions of lubrication and cooling and is suitable for high-speed running ring gears. However, oil mist lubrication may cause certain pollution to the environment.
Drip lubrication is to drip lubricating oil onto the friction surface of the ring gear through an oil pump. This method is suitable for low-speed, light-load ring gears and has the advantages of simple structure and easy maintenance. But the amount of oil dripping needs to be precisely controlled to avoid waste and pollution of the environment.
Circulating lubrication is to circulate the lubricating oil to the friction surface of the ring gear through the lubrication system, and collect the return oil for filtration and cooling before reuse. This method is suitable for ring gears that require continuous and stable lubrication, and has good heat dissipation and lubrication effects.
In some special cases, solid lubricants can also be used to lubricate the ring gear. Solid lubricants are generally resistant to high temperatures and wear, and can provide effective lubrication protection under extreme conditions.
