High speed lubricator using felt gear

The present invention relates to a high speed lubricator using felt gears. More specifically, as a contact lubrication device of a rack / pinion gear, a felt gear made of wool, which receives and stores lubricating oil from inside, meshes with the rack or pinion gear to rotate at a high speed, and forms an oil film on the rack or pinion gear. This eliminates the need to stop the rack / pinion gear unit for lubrication, and can be easily replaced with felt gears suitable for the shape and dimensions of the rack or pinion gear, making it compatible with rack / pinion gears of various shapes and dimensions. The present invention relates to a high speed lubricator using felt gears.

Rack and pinion gears are a type of power train that converts rotary motion into linear motion or linear motion into rotary motion.

Racks and pinion gears are widely used in a variety of industrial machinery, including automotive steering and machine tool feeders.

On the other hand, these power trains have greases on the tooth surface for the purpose of preventing the tooth surface from melting due to contact friction under extended load conditions, extending the life through wear protection, removing the heat generated by the cooling effect, and preventing dust or foreign substances from entering the environment. Lubrication should be performed to form a protective oil film using lubricating oil.

However, rack / pinion gears used in high-speed feed systems, including robot carriages and gantry conveying systems, do not have adequate lubrication, and the operator manually applies lubricating oils such as grease to the rack / pinion gears. It was taking a way of doing it.

However, this manual method does not provide smooth and reliable grease supply to the rack / pinion gear, resulting in poor film formation, resulting in poor component integrity, and also stops the rack / pinion gear from running for grease supply. As a result, the working efficiency is lowered as a result, and the use of excessive lubricating grease causes environmental pollution.

Therefore, the lubrication can be performed smoothly without stopping the gear driving state for lubrication of the rack / pinion gear, and the life of the device can be extended by using a small amount of lubricant, and the rack / There is a need for a new lubricator that can be applied to pinion gears.
