When the working environment temperature of the reducer exceeds 60°C, what cooling measures should be taken?

When the working environment temperature of the reducer is higher than 60 ℃, the following cooling measures can be taken:

Improve ventilation conditions

Increase air circulation: Ensure sufficient space around the reducer to avoid being surrounded by debris accumulation, and reserve at least 50cm of heat dissipation space. Exhaust fans or ventilation ducts can be installed in the workshop to enhance air flow and remove the heat emitted by the gearbox. For reducers installed in enclosed spaces, such as in control cabinets, it may be considered to add heat dissipation holes or ventilation fans to promote air circulation.

Install heat dissipation fins: Install heat dissipation fins on the gearbox housing to increase the heat dissipation area and improve heat dissipation efficiency. The heat dissipation fins are usually made of metal materials with good thermal conductivity, such as aluminum or copper, which can effectively transfer the heat inside the gearbox to the outside air.

Using forced air cooling: Install a fan near the reducer or its casing to remove heat from the surface of the equipment through forced airflow. You can choose between axial flow fans or centrifugal fans, and determine the specifications and quantity of fans based on the size and heat dissipation requirements of the reducer. The installation position of the fan should ensure that the airflow can effectively cover the heating parts of the reducer, such as the motor, gearbox, etc. In addition, a temperature control switch can be used to control the operation of the fan. When the temperature of the gearbox reaches a certain threshold, the fan automatically starts to dissipate heat.

Using a liquid cooling system: The liquid cooling system uses a dedicated coolant, such as water or specific cooling oil, to flow through the gearbox housing or internal cooling channels, and remove heat through a heat exchanger. This method has good cooling ability and is suitable for environments with high loads and harsh working conditions. A dedicated water cooling circulation system can be set up to transport the coolant through pipelines to the cooling channel of the gearbox, and then reflux back to the cooling device for cooling and recycling. When designing a liquid cooling system, it is necessary to consider parameters such as coolant flow rate, temperature, and pressure to ensure cooling effectiveness and system stability.

Optimize lubrication system

Choose the appropriate lubricating oil: Based on the working conditions and requirements of the gearbox, choose lubricating oil with good heat dissipation performance and high temperature stability. High quality lubricating oil can form a good oil film on the surface of components such as gears and bearings, reducing friction and wear, while also helping with heat dissipation. For example, some synthetic lubricants have lower viscosity and higher flash point, which can maintain good lubrication performance and heat dissipation effect at high temperatures.

Regularly replace lubricating oil: maintain the cleanliness and good performance of lubricating oil, regularly check the quality and oil level of lubricating oil, and replace lubricating oil according to the prescribed cycle. As the usage time increases, the lubricating oil will gradually age and become contaminated, and its heat dissipation and lubrication performance will decrease. Timely replacement of new lubricating oil can effectively reduce the temperature of the gearbox
