What are the effects of extreme temperature environments on the transmission performance of slewing drives?

The U-TRSM design engineers often encounter high or low temperature environment in the process of discussing solutions with the customers, so in these extreme temperature environments, what will be the impact on the transmission performance of the slewing drive? Here is a brief analysis:

Tempered and quenched gears can usually be operated properly in the temperature range of -40°C to 250°C. The material is suitable for most industrial applications. In this temperature range, the mechanical properties and dimensional stability of the material are good enough to meet the requirements of most industrial applications.

At higher temperatures (over 250°C), although the tempering treatment improves the heat resistance of the material, there is still a gradual decrease in the hardness and strength of the material, which may lead to a reduction in the load carrying capacity and wear resistance of the gear. Therefore, if it is necessary to use it in a high-temperature environment, it is recommended that appropriate cooling measures be taken or that a more heat-resistant material be selected.

At very low temperatures (below -40°C), the toughness of gears decreases and their brittleness increases, making them susceptible to brittle fracture. Therefore, if it is necessary to use in a low-temperature environment, it is recommended to take appropriate heating measures or choose a material that is more resistant to low temperatures.

In high-temperature environments (over 150°C), a synthetic lubricant or grease that is resistant to high temperatures should be selected to ensure lubrication.

At low temperatures (below -40°C), a low viscosity lubricant or low temperature grease should be selected to ensure lubrication at start-up.

Design effective cooling system such as air-cooled, water-cooled or oil-cooled to control the temperature of the gearbox in high temperature environment. Installation of temperature sensors to monitor the temperature of the gearbox in real time to ensure that the temperature does not exceed the safe range.

Design effective heating system in low temperature environment, such as electric heating or hot air heating to increase the temperature of the gearbox. Install temperature sensors to ensure that the temperature is within the safe range. Regularly check the wear of gears, the state of the lubrication system and the accuracy of temperature sensors to find and solve problems in time. Ensure the normal operation of the lubrication system and replace worn parts in time.

U-TRSM designs and manufactures gear slewing drives, which are generally material tempered and tooth hardened, and gear transmission is suitable for operation in temperatures ranging from -40°C to 250°C. The reliability and service life of gear transmission system in different temperature environments can be ensured by proper lubricant selection, cooling and heating system design, as well as regular maintenance and inspection.
