Description

A kind of multifunctional industrial gear lubricating oil composition
Technical field
The present invention relates to a kind of a kind of industrial gear used under the conditions of lubricant oil composite, more particularly to varying environment dress Put (gear-box, reduction box and other gear transmission systems) lubricant oil composite.
Technical background
Gear in various mechanical transmission mechanisms, broad categories, purposes are different.According to its axis mutual alignment relation not Together, the driving of parallel axes, driving of intersecting axes and crossed-axes gear drive can be divided into.Bu Tong have again by the shape of gear and tooth in transmission per class The different kind of drive, such as the straight spur gear of the driving of parallel axes, helical gears, double helical tooth roller gear；Concurrent aces Transmission has straight bevel gear, helical bevel gear, spiral bevel gear；Crossed-axes gear drive has hypoid gear, worm and gear, spiral shell Rotation transmission.Industrial gear oil is the special lube required for industrial gear drives, mainly includes exposed gear oil, enclosed Gear oil and worm and worm wheel oil.On the whole, the states for being in mixed lubrication, existing fluid moves the lubrication feature of industrial gear more Hydrodynamic lubrication, and flexible fluid lubrication, also boundary lubrication.Industrial gear oil should have suitable viscosity, relatively light negative to ensure Lotus moment forms fluid dynamic film and elastohydrodynamic film, requires have suitable additive component to ensure in higher load again Moment (period) forms boundary lubricant film.In general, gear-driven efficiency is high, compared with bearing, the equivalent curve half of gear Footpath is small, and its surface is not easy to form oily contract in relative motion.When gear enters boundary lubrication condition, the activity member in gear oil Element can react with metal, and dispersed formation boundary lubricant film, so as to reduce the abrasion of the flank of tooth；Geared teeth and tooth Between be linear contact lay, therefore, contact area is small, and contact unit stress is big, gear in engagement process, while exist slide and roll Two kinds of forms of motion, and sliding speed size and Orientation drastically changes using position as boundary.Because friction produces substantial amounts of heat, Gear oil needs to take away heat, to prevent flank of tooth temperature from raising；The lubrication of gear is discontinuity, when two gears engage every time It is required for re-establishing oil film, the covering of oil film can not only reduce abrasion, can also completely cut off air and water, prevent the corruption of the flank of tooth Lose and get rusty；Due to machining accuracy limit, flank of tooth finish is poor, and oil film is easily rupturable under high loads, occur flank engagement or Abrasion, therefore gear oil should play a part of the abrasive particle or impurity on the flushing flank of tooth, so as to mitigate the vibration of gear, reduction is made an uproar Sound, it is gear drive even running；Gear drive not only Line Contacts, also sliding contact, particularly hypoid gear, Wheel between cog has higher relative sliding velocity.This can make oil film thinning or even partial fracture under big loading condiction at a high speed, cause Friction and wear aggravates, or even causes scratch and occlusion.
In view of gear structure is different, operating mode is different, therefore distinct device is often selected specifically for the equipment in specific work Suitable oil product under the conditions of condition carries out gear lubrication, and be difficult with general oil product come meet different structure, distinct device, Gear lubrication under different operating modes.Multifunctional gear fluid composition of the present invention, it can meet that multi-form (open type, is closed Formula), different load (light, in, heavy load), distinct device (gear-box, reduction box and other gear transmission systems) and not The lubrication needs of equipment under same environmental condition (very big etc. specific condition of temperature change under indoor and various severe outdoor environments).This The composition of invention is also resisted in addition to base oil using specific multifunctional lubricant, a variety of ashless oxidation inhibitor optimum organizations, extreme pressure Grinding agent combines, and compounds suitable detergent-dispersant additive, gives full play to the cooperative effect between additive.The lubricant oil composite has There are good mobility, extreme pressure anti-wear, an anti-oxidative stability, certain anti-rust and corrosionproperties, resistance to emulsion, water resistance, from And meet the lubrication needs that gear-box and reduction box use under various special environment conditions.
