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.
