The purchase of a coal washing machine is definitely aimed at achieving better results and increasing efficiency, and the smoothness of the gears directly affects its production efficiency. This requires us to delve deeper into what factors affect gear smoothness? Next, I will give you a detailed explanation.

　　1. Temperature

　　When the temperature drops, the smooth oil will thicken. When the temperature rises, it will become thinner. Therefore, low viscosity smooth oil is required under low temperature conditions, while heavy oil is required under high temperature conditions to prevent dry contact between metals.

　　2. Load

　　High viscosity oil is more resistant to heavy loads and prevents collisions between metals than thin oil. Therefore, light loads require low viscosity smooth oil, while high loads require high viscosity smooth oil.

　　3. Speed

　　The faster the sliding and rotating speed, the less time the smoothing agent is squeezed between the gears. At the same time, smooth oil is more prone to clumping and thickening during high-speed operation. Therefore, use high viscosity and heavy oil at low speeds, low viscosity oil and thin oil at high speeds.

　　4. Gear category

　　When using straight teeth, helical teeth, herringbone teeth, and bevel gear pairs, sliding and rotation will generate a useful oil film to slow down the direct contact between the meshing teeth. The purpose of relative sliding operation is not conducive to adhering to the oil film in the installation of non equiaxed transmissions such as turbine vortex rods and hyperbolic gears in coal washing machines. In this transmission installation, there is often a large amount of smooth border. Therefore, heavy oil is still required for the installation of turbine rods and large eccentricity hyperbolic gear transmissions. When these transmission installations are subjected to heavy loads and high pressures, it is necessary to choose smooth oils with high viscosity, smoothness, smoothness, or even extreme pressure enhancers that possess high-strength oil film characteristics.

　　5. Instantaneous pressure

　　The rhythmic force emitted by the engine requires a smooth border compared to the thick oil to prevent the instantaneous consolidation of the oil film, as only a small amount of smooth oil can be left behind. In this case, a smoothing oil containing an extreme pressure booster is required.

　　In summary, these are the factors that affect the smoothness of the coal washing machine gears. Seeing this, I believe you have gained some understanding of it, and we can refer to the above knowledge to avoid gear rust.
