Worm gear and worm are a type of gear, often used to transmit motion and power between two interlocking shafts, and are widely applied in various motion and power transmission devices, such as worm gear and worm reducers.
Types of Lubricating Oil for Worm Gears and Worms
At present, the lubricating oils used for worm gears and worms include the following types:
Mineral-based gear oil:
One type is the special lubricating oil for worm gears and worm wheels. This type of gear oil is added with fat additives to provide lubrication for the sliding between the teeth of worm gears and worm wheels, reducing the friction between the tooth surfaces.
Another common type is mineral extreme pressure gear oil (EP), which contains sulfur and phosphorus extreme pressure additives. However, if this type of gear oil comes into contact with copper-containing components, it may cause corrosion. If this type of gear oil is used, it is fine when the temperature is low, but when the temperature is high, it will cause corrosion of copper-containing components. If the gears in contact with the oil do not contain copper, this type of gear oil can be used.
Synthetic gear oils: Mainly include PAO and PAG.
PAO (Polyalphaolefin), also known as polyalphaolefin, has excellent lubricity and is therefore very suitable for applications involving a lot of sliding friction, such as worm gears and worm gears. Similarly, when choosing this type of synthetic oil, remember to check if there are sulfur-phosphorus type extreme pressure additives in the composition.
- PAG (Polyalkylene glycols) polyether synthetic oil also has excellent performance and is gradually becoming popular. The characteristic of PAG is that it is particularly lubricated and completely free of paraffin. At low temperatures, paraffin wax solidifies. The poor flu
