Transmission should not use hypoid gear oil

Some car owners and car maintenance sbb key programmer personnel, lack of understanding of the characteristics of hypoid gear oil, one-sided hypoid gear oil performance than conventional gear oil, therefore, no off-the-shelf conventional gear oil, or to "care for" vehicle hypoid gear oil instead of conventional gear oil added auto gearbox. Little did he know that it will not only bring unnecessary economic losses (hypoid gear oil more expensive), but will also cause the the transmission gears corrosive wear is not conducive to the normal work of the transmission.
Hyperbolic gear meshing ride comfort, reduction ratio and other characteristics, widely used in automobile rear axle main reducer gear. However, hyperbolic gear meshing transmission process, passing the pressure is very high (up to 4000MPa), the relative sliding speed up to 400m/min, resulting in high instantaneous temperature (600 to 800 ° C), and general oily additives desorption from the friction surface is about 100 ℃, the film was destroyed. Under such extreme pressure conditions, in order to prevent wear and tear, scratches and adhesive, it is necessary to reduce the friction of the metal contact surface, and the hypoid gear oil chlorine, sulfur, phosphorus and other 
AUTOCOM CDP Pro  elements of the organic compound is added as an extreme pressure additive.
For ordinary gear (often involute line gear), the tooth surface units lower pressure (2001 to the modulus of elasticity is 3,000 MPa or), and the working temperature is not high, generally lower than 90 ° C, so the film is not easily broken, better lubrication conditions, do not have to use a very pressure additive. Hypoid gear oil, from the extreme pressure additive mechanism that is bound to have some additive effect, so that the gear unnecessary corrosion and wear.
So simple that hypoid gear oil performance, can replace conventional gear oil, this view is not correct, but should be in accordance with the characteristics of the gear, the choice of a suitable performance gear oil.
