Characteristics of open gear lubricants

Open gear machinery has special characteristics for its equipment transmission due to its use conditions and special use. The lubricant used in the application has a different performance than the closed gear oil. Conventional asphalt open gear lubricants will be difficult to meet the lubrication requirements of modern open gear machines and the needs of users. The recyclable, sprayable open gear oil will be the leading lubricant for open gear equipment.
In the process of open gear lubrication, the gear surfaces are only covered by a thin layer, they are often under boundary lubrication conditions. Because the new film or grease added to the tooth surface is squeezed out due to the pressure of the tooth surface, combined with the centrifugal force during the rotation of the gear, only a thin oil film can be left on the tooth surface. Considering the grinding cooperation of the gears, the open gear lubricating oil must have good adhesion and viscosity to ensure that a continuous oil film is kept on the gear surface, which provides enough for the tooth surface running under low speed and heavy load. The oil film thickness is not easily washed away.
The operation characteristics of the open gear are low speed, heavy load and continuous operation, which causes the lubrication of the gear to be in the boundary lubrication state. Therefore, it has good extreme pressure performance and wear resistance to ensure the strength of the oil film. It is the open gear oil of today. The main features that must be available.
In addition, according to the characteristics of open gears, open gear lubricants should also have good rust resistance, oxidation resistance, low temperature pumpability and so on.
