details Gear oil is a low viscosity lubricating oil, dedicated to maintaining the driving force components of the transmission system, generally accompanied by a clear smell。Vehicle gear oil is used in two ways: characteristic classification and viscosity classification。At this stage, the classification of British Petroleum's (API) characteristics and the British military gear oil specifications have been widely used around the world。Most of the lubrication fluids and distinctions used for manual transmissions depend on quasi-single lobe hyperboloid gear oils。They include fire resistant hydraulic oil (EP) preservatives and wear resistant preservatives to be directed towards the drive of a single blade hyperboloid bevel gear。
When the vehicle gear oil is working, because the working surface of the gear continues to change and the temperature does not rise significantly, its operating temperature is generally 10 ° C ~ 80 ° C。Second, gear oil should bear high pressure。When the gear transmission system is used, the working pressure of the interlip tooth combination part reaches (196 ~ 245) ×10kPa, and the working pressure of the hyperbolic gear reaches (294 ~ 392) ×10kPa。In addition, the gear oil works under the standard of large rate transformation and many revolutions, so the gear oil is very easy to squeeze from the gap in the middle of the teeth, resulting in semi-liquid friction。
Vehicle gear oil regulations：
The key requirement of vehicle gear oil is the ability to produce a continuous and firm oil film on the surface in the middle of the teeth，It has a high oil content，And maintain a hard boundary oil layer in the middle of the transmission system components to ensure that the transmission system components reduce wear and scratch;besides，Gear oil should also have excellent viscous-temperature characteristics，To ensure minimal friction damage to the drive transfer tissue，Increase transmission speed and ensure easy starting of the car (especially in winter)。
