Abstract
The present invention relates to gear oil fields, especially noise reduction type gear oil.The gear oil all the components mass percent is as follows: naphthenic base oils 76-80%, sodium naphthenate 1~5%, sodium tetraborate 1~9%, rust resistance and corrosion resistance additive 1~3%, matal deactivator 1~5%, anti-foaming agent 1~4%, surplus are oleamide.The invention is more more mute than conventional gear oil.
Description
Technical field
The present invention relates to gear oil fields, especially noise reduction type gear oil.
Background technique
Gear oil based on petroleum oil base oil or synthetic lubricant fluid, be added extreme pressure anti-wear additives and oiliness improver modulation and
At the important lubricating oil of one kind.For various gear assemblies, to prevent tooth surface abrasion, scratch, sintering etc., extending it makes
With the service life, transmitting power efficiency is improved.Gear oil should have good wear-resistant, load resistance energy and suitable viscosity.In addition, also
Should have good thermal oxidation stability, anti-foaming property, water separable performance energy and rustless property.Since gear loading is generally all 490
More than megapascal (MPa), and hyperbola flank of tooth load is more up to 2942MPa, to prevent rupture of oil film from causing tooth surface abrasion and scratch,
It is commonly incorporated into extreme pressure anti-wear additives in gear oil, generallys use sulphur-phosphorus or sulphur-phosphor-nitrogen type additive.But existing gear oil
It is not mute.
Summary of the invention
In order to overcome the shortcomings of that existing gear oil is not mute enough, the present invention provides noise reduction type gear oils.
The technical solution adopted by the present invention to solve the technical problems is: a kind of noise reduction type gear oil, all the components quality
Percentage is as follows: naphthenic base oils 66-80%, sodium naphthenate 1~5%, sodium tetraborate 1~9%, rust resistance and corrosion resistance addition
Agent 1~3%, matal deactivator 1~5%, anti-foaming agent 1~4%, surplus are oleamide.
Specifically, the naphthenic base oils 66%, sodium naphthenate 5%, sodium tetraborate 9%, rust resistance and corrosion resistance additive 3%,
Matal deactivator 5%, anti-foaming agent 4%, surplus are oleamide.
Specifically, the naphthenic base oils 76%, sodium naphthenate 2%, sodium tetraborate 3%, rust resistance and corrosion resistance additive 2%,
Matal deactivator 3%, anti-foaming agent 2%, surplus are oleamide.
The invention has the advantages that the invention is more more mute than conventional gear oil.
