What are the effects of excessive lubricating oil on WPS40-30:1-A worm gear reducer

Excessive lubricating oil has the following effects on the WPS40-30:1-A worm gear reducer:

Poor heat dissipation: Excessive lubricating oil will occupy the limited space inside the gearbox, hinder air circulation, and affect heat dissipation. At the same time, when the lubricating oil is stirred, more heat is generated, and the heat dissipation space is relatively reduced, which will cause the oil temperature to rise. Long term high temperature can reduce the viscosity of lubricating oil, leading to poor lubrication and exacerbating the wear of bearings and gears.

Increased risk of leakage: Excessive lubricating oil can increase the internal pressure of the gearbox. For labyrinth oil seals, excessive oil level can cause seal failure and oil leakage; If it is a skeleton seal, an increase in oil temperature will cause changes in the original seal design parameters, deteriorate the working environment of the inner lip of the skeleton seal, intensify aging, and ultimately lead to oil leakage. This not only causes waste of lubricating oil, but also pollutes the working environment. If it leaks to critical parts of the equipment, it may cause other malfunctions.

Power loss and efficiency reduction: During the operation of the gearbox, excessive lubricating oil will be violently stirred by gears and other components, increasing oil stirring loss and increasing frictional resistance inside the gearbox, resulting in power loss, decreased equipment operating efficiency, and increased energy consumption.

Poor lubrication effect: too much lubricating oil is prone to produce foam when moving, and foam will reduce the viscosity and bearing capacity of the lubricating oil, reduce the thickness of the lubricating oil film, affect its effective lubrication effect, and even cause direct metal contact, increasing wear. In the long run, it may also cause failure modes such as pitting corrosion in bearings and gears that rely on lubricating oil lubrication.

Impact on operational stability: In some situations where high positioning accuracy is required, without closed-loop control, excessive lubricating oil may cause unstable speed of the gearbox. In addition, abnormal noise and vibration may also be caused by uneven thickness of the lubricating oil film.
