Lubrication of Non-Lubricated Gear and Roller Drives
A typical non-lubricated gear and roller drive is made of metal-to-metal helical gearing. The problem with this type of drive is that it is not very reliable due to the high level of friction and endangered race geometry. This is where the lubrication comes in. While oil bath lubrication can be effective in some applications, it can be expensive and harmful. The non-lubricated gear and roller drive offers some advantages.

To measure the lubrication levels, the researchers used a twin-disk tribometer to record the contact voltage and tooth bulk temperatures. The results were then repeated on the same gear at FZG Gear Efficiency Test Gear. Figure 12 shows the comprehensive results of the experiment. The measured failure torques are a function of pitch factor and the Hertzian stress at the pitch factor. The failure torques differ for different speeds and depending on the life of the product and its seal. Proper lubrication prevents premature failure and extends the life of equipment.
The fluid-film lubrication used in the tests had a very small influence on the coefficient of friction. Its thickness increased gradually with increasing pitch line velocities. At a high pitch line, the coefficient of friction was 0.008 and 0.060 respectively. The water-containing gear fluids, however, had a large impact on this value. In general, fluid lubrication results in the lowest coefficient of friction.
Using the wrong type of oil for a gearbox can cause several problems. Choosing the wrong lubricant can lead to a shorter life span of the lubricant and reduce reliability. A professional should be consulted for these matters if you are unsure which type of lubricant to use. But if you are unsure about the type of oil, do not hesitate to contact a gearbox expert.
When applied to the gear shaft of a non-lubricated gear, water-containing gear fluids exhibit similar losses as conventional gear oils. However, water-containing gear fluids suffer more loss when they are subjected to high pitch line velocities. As such, gear fluids with a water-based composition may be more advantageous for non-lubricated gears. They show similar load-dependent losses compared to conventional gear oils.

The recommended lubricant table for worm gears provides specific information on which lubricants are suitable for this type of equipment. Some of these additives have non-corrosive effects, while others are toxic. They should not be used in a toxic environment or in machines where they could potentially harm other parts. If possible, consult the owner's manual or service manual to ensure your worm gears are lubricated properly.
When performing an efficiency test, it is important to evaluate the efficiency of the gears. In a test rig, you can assess the power loss and temperature behavior of gears. The rig uses back-to-back configuration with a center distance of 91.5 mm. In addition, it is very easy to operate and requires no external lubrication. This enables the user to increase the life span of a gear while reducing expensive downtime. Check out this post that has expounded more on this topic: https://en.wikipedia.org/wiki/Gear.
