What is the difference between oil lubrication and grease lubrication for slewing drives?

In the slewing drive design process, U-TRSM often encounter customers using oil lubrication conditions. In our standard design, many solutions are designed and manufactured in accordance with the grease lubrication, oil lubrication needs to improve the overall protection level of the slewing drive, this article will discuss the difference between oil lubrication and grease lubrication.

Oil lubrication is mainly suitable for slewing drive applications in high speed, heavy duty and high temperature occasions, has a better cooling effect, can take away the heat generated by the friction of the gears, and can better to improve the anti-corrosion and anti-wear performance. For example, our product 2 series 0411 is oil-lubricated and specially designed so that the speed of this slewing drive can reach more than 100 rpm. The cost of oil lubrication is high, and customers need to have a complete set of oil circulation system and auxiliary workpieces to ensure the quality of oil.

Grease lubrication is simple, convenient and economical. Suitable for use in occasions that are not easy to maintain or difficult to fill grease, grease can form a protective film on the tooth surface to reduce friction and wear, but the cooling effect of grease lubrication is very poor, is not conducive to take away the heat generated by tooth friction, and is more susceptible to contamination and oxidation, the slewing drive designed by U-TRSM is a fully protected design, used under the conditions of the technical requirements, maintenance and grease filling time is generally half a year to once a year, and even once every 2 years for the better working conditions of the environment.

The lubrication way mainly depends on the application scenario and needs, we should deal with problems case by case. the U-TRSM design engineers will provide customers with more quality solutions, as long as you can think of it, the U-TRSM can boldly try, continuous innovation, and constantly learn new technologies.
