How to choose open gear lubricant in autumn and winter

The weather is slowly turning cold. The temperature difference between the whole country and the country is large. The load per unit area of the open gear tooth surface is high, and the tooth surface is in line contact, which is easy to generate noise and vibration. Therefore, it is necessary to choose a suitable open gear lubricant. important.
According to the analysis of professionals, the temperature drop in the autumn and winter seasons is more obvious. The ordinary open gear lubricants have lower fluidity at lower temperatures, and the lubrication time of the open gears takes longer. Therefore, it is recommended to choose open gear lubricants, which should be considered seasonally.
We know that the characteristics of the open gear transmission are that the gear diameter is large, and there is no closed gear box, the lubricating oil is easy to be lost, and it is difficult to form a liquid oil film;
These require oils that are extremely viscous, highly adherent, and extremely resistant to extreme pressure. There are several open gear lubricants available on the market today:
1. Spray type, which has good adhesion and can be applied to the gear meshing position through the automatic spray device. It is solvent-free, environmentally friendly and energy-saving. It is a good lubricant for modern open gear transmission.
2, asphalt type, the price is cheap, but the viscosity is not good, the summer is easy to lose, the winter is difficult to flow.
3, fat type, strong adhesion, oil film thickness at high temperature, but it is not convenient to add and change oil, it needs to be applied manually.
4, solvent type, due to the dilution of the solvent, easy to apply, but must be used up as soon as possible after opening, and the solvent volatilization is not good for the environment and the health of workers.
