Heat Dissipation Methods for Cycloidal Pinwheel Reducers

Heat Dissipation Methods for Cycloidal Pinwheel Reducers. In normal operation, the working temperature of the lubricating oil inside a cycloidal pinwheel reducer should not exceed 90°C. If the temperature becomes too high, it can alter the physical and chemical properties of the oil. For instance, it can reduce the oil’s viscosity, decreasing the load-bearing capacity of the oil film, which may eventually lead to direct contact between the working gear surfaces and cause gear surface welding.

There are three main heat dissipation methods for cycloidal pinwheel reducers, as outlined below:

1. Natural Cooling

• Description: When the standard casing does not provide sufficient heat dissipation, additional heat dissipation fins can be added to the exterior of the casing. The design of these fins should ensure that air can circulate naturally, helping to dissipate the heat from the reducer.

2. Fan Cooling

• Description: If natural cooling alone is insufficient, Using a fan cooling. A fan is used to force air over the surface of the reducer, enhancing heat transfer and improving cooling performance.

3. Water Cooling

• Description: Equipped with serpentine water pipes, typically made from copper or brass. Cold water circulates through these pipes, absorbing heat from the lubricating oil and effectively reducing the oil temperature.

These cooling methods are essential for maintaining the proper working temperature of the reducer, ensuring optimal performance and extending the lifespan of the components.
