stay jiangmen ceiling fan Various types of smooth oil are widely used in equipment, including smooth oil for connecting parts, smooth oil for fan blades, and smooth oil for reducer gears. The most important among them is smooth oil for gears, as it directly affects the operation of Jiangmen ceiling fans. For many years, improper selection of smooth oil products has often caused failure of the tooth surface of electric fans, resulting in a considerable amount of gear scrap. Improper smoothness increases the cost of accessories, increases operating costs, and results in the loss of suitable fans. Reasonable selection of smooth oil has important economic significance.

In the gear transmission of the Jiangmen ceiling fan motor, the meshing time of the two corresponding mating surfaces of the gears is very short, and sliding and rolling occur intermittently during meshing. The active role of forming a liquid oil film is very weak, and due to processing and installation errors, the actual contact area is very small. Therefore, the pressure received per unit area is large, resulting in high angular stress on the tooth surface. This stress is the root cause of tooth surface failure (tooth surface abrasion, pitting, ripple, detachment). Whether smooth oil can act as an elastic medium to separate two contact tooth surfaces and fulfill the mission of maintaining tooth surfaces is crucial.

Tooth surface failure (commonly known as tooth shape distortion) leads to a decrease in transmission stability, increased oscillation and noise, accelerated tooth surface wear, and earlier failure cycles, resulting in Jiangmen ceiling fan users having to repair and replace the motor early.

In order to adapt to different contact stresses and maintain the gear tooth surface from damage, in addition to improving the accuracy of tooth surface processing and installation, it is necessary for smooth oil to have the required load capacity, namely wear resistance and extreme pressure resistance. Load capacity is the most important basic function of gear smooth oil. How can gear smooth oil have this function? This relies on additives to achieve this requirement. The additives that can improve the load capacity of smooth oil now mainly include sulfides, phosphides, chlorides, borides, lead soaps, etc. Sulfides and phosphides are currently the most commonly used additives. When the above-mentioned additives and auxiliary additives are added to the smooth oil, the following effects can be achieved in gear smoothness:

(1) Avoid or reduce the wear of gears and related moving parts;

(2) Reduce friction and power loss;

(3) Reduce noise, reduce oscillations, and mitigate impacts between gears;

(4) Avoid corrosion and rust.

In the past, we only considered the smoothness of gears in terms of viscosity, oily working conditions, environmental temperature, etc., and gave little comprehensive consideration to factors such as extreme pressure resistance, oxidation resistance, emulsification resistance, and corrosion resistance. Even in some product manuals, the selection of smooth oil is not appropriate, so it does not work well in gear smoothness. In recent years, with the advancement of equipment skills, new requirements have also been put forward in terms of smoothness. Now, China has made significant progress in gear smoothness, with its own new series of specifications that can rival the same types of advanced industrial countries in terms of functional parameters. Through trial use, gear oil has improved by two to five times compared to previous mechanical oils in terms of extending gear life and oil change period.
