What are the changes in the working efficiency of ZQD400-100-81.7 gear reducer under different humidity environments

At present, there is no specific research or data on the efficiency changes of ZQD400-100-81.7 gear reducer under different humidity environments. However, the general principles and characteristics of gear reducer can be used to analyze its efficiency changes under different humidity environments.
Low humidity environment

In low humidity environments, the impact on the efficiency of the gearbox is generally relatively small. If the humidity is below a certain level, such as below 20%, it may slightly increase the viscosity of the lubricating oil, but within the normal operating temperature range, this change usually does not have a significant negative impact on the lubrication effect and transmission efficiency. At the same time, a low humidity environment is also beneficial for the heat dissipation of the gearbox, as dry air is more conducive to heat conduction and dissipation, which can keep the gearbox at a relatively low temperature during operation, helping to maintain the performance of lubricating oil and the normal working state of components such as gears and bearings, thereby maintaining a high working efficiency of the gearbox, usually within its rated efficiency range. For example, the average efficiency of ZQD series gearboxes can be maintained at over 90%.

High humidity environment

Decreased lubrication performance: When the humidity is high, such as exceeding 80% or even approaching saturation, water vapor in the air may mix into the lubricating oil of the gearbox. This will cause changes in the performance of the lubricating oil, such as a decrease in viscosity and a thinning of the lubricating film thickness, resulting in increased friction between moving parts such as gears and bearings, increased energy loss, and decreased work efficiency. In severe cases, the lubricating oil may experience emulsification, greatly affecting the lubrication effect and significantly reducing the efficiency of the gearbox.

Increased risk of electrical component failure: If ZQD400-100-81.7 gear reducer contains electrical components, high humidity environment will reduce the insulation performance of electrical components, increasing the risk of short circuit and electrical failure. Once there is a problem with the electrical components, it will directly affect the operation of the gearbox, leading to a decrease in work efficiency or even shutdown.

Poor heat dissipation effect: In high humidity environments, the thermal conductivity of the air will change, and moisture will to some extent hinder the transfer of heat from the inside of the gearbox to the outside, making it difficult for the gearbox to dissipate heat. This will cause an increase in the internal temperature of the gearbox, which in turn affects the performance of the lubricating oil and the thermal stability of the components, resulting in a decrease in efficiency.

Corrosion of metal components: High humidity environments can easily cause rusting and corrosion of metal components in gearboxes, especially in critical areas such as gear teeth and bearing surfaces. Corrosion can damage the surface accuracy and smoothness of components, increase friction losses, reduce transmission efficiency, and also affect the strength and service life of components.

In order to reduce the impact of humidity on the working efficiency of ZQD400-100-81.7 gear reducer, some measures can be taken, such as ensuring good sealing performance of the reducer to prevent moisture from entering; Choose lubricants suitable for high humidity environments; Regularly inspect and maintain the gearbox, promptly identify and address issues such as rust, corrosion, or lubrication.
