Information About Worm Gear Lubrication

To reduce the speed and to increase the torque, worm gears play a crucial role. These gears are quite compact and can achieve very high-speed ration, in general, 60:1 or more than that. But because of the high speed, these gears generate too much heat. That's why special kind of lubrication is required. You can easily find chain lube in UAE for your worm gears. Because of the high demand, the suppliers of lubricants are increasing day by day. So they can be easily available nearby your areas. 

The connection between worm gears and worms take place with the help of sliding rather than rolling. Because of this high amount of friction takes place and that generates high temperature. Worm gears may operate to almost double the temperature compared to other gear configurations such as spur gears.

 

Worm gears work with the sliding motion, and at the same time the worm rubs off the lubricant film while working with the worm wheel. After disengaging, the worm surface takes a high amount of lubricant, but it's really difficult to measure that it will have a lubricant film that is thick enough to last through the load zone. That's why worm drives require high viscosity lubricants. They must have good lubricity to come out of the high-load metal-to-metal contact.

Here Are The Main Four Types Of Lubricant Used With Worm Gears:

• Compounded mineral oils
• Extreme pressure (EP) mineral oils
• Polyalphaolefin (PAO) lubricants
• Polyalkylene glycols (PAG) 

If the no brass components are present in the material, at that time you can use mineral-based extreme pressure gear oils. This lubricant is not suitable with brass because it reacts with the sulfur-phosphorous additives found in these oils. If you are working with steel gears, then EP oil is the best lubricant. To prevent sliding wear, you can go with PAO gear lubricants because of its good lubricity properties. The checking of the additive is required to make sure that the oil is compatible with the gear materials. 

PAG lubricants are new in the industry but most of the people are currently using this lubricant because of its amazing lubricity. This lubricant also contains high viscosity. You can choose it for low or high-temperature operation. But, keep in mind that his lubricant is not compatible with some mineral oils, seals and paints.
