Lubricating oil = base oil + thickener + additive, in which base oil is the main component of grease. The role of thickener is like sponge, and lubrication is based on base oil. In the process of use, we should pay attention to the condition of grease. If there is oil leakage, we should deal with it in time. The loss of base oil causes the grease to fail to provide sufficient lubrication protection, and the equipment is prone to wear. The main reasons for the loss of grease in use are chemical reasons, physical factors and impurities.
Due to the influence of heat and surrounding gas in the friction and lubrication area, the base oil and thickener are oxidized resulting in the destruction of the soap structure of the grease and the loss of softening in use. Therefore, we should check the surrounding environment of the grease. whether it is close to the heat source, and whether the presence of special chemicals causes the grease to be affected.
The environment of the lubricating part and the medium it contacts have a great influence on the performance of the grease. So we should carefully consider when selecting the grease.

( 1 ) The amount of grease should be appropriate Too much grease will increase the friction torque, temperature and fat consumption. If the amount of fatliquoring is too small, the reliable lubrication cannot be obtained and dry friction occurs. Generally speaking, the appropriate amount of grease is 1 / 3 ~ 1 / 2…
1.Excessive bearing grease will not only fail to lubricate, but also have many negative effects. – – Taking bearings as an example,add excessive bearing grease, which will lead to increased bearing rotation resistance, increased temperature and energy consumption, and increased temperature will also cause grease oxidation，Speed up ( early deterioration, oil service life is shortened…
