It is shown in Table 1 by the property indices of the gearbox lubrication agent prepared by said gear case lubricant compositions I-IX：
The property indices of gearbox lubrication agent prepared by 1 gearbox lubrication agent composition of table
From the gearbox lubrication agent I- that can be seen that in the property indices of 1 gearbox lubrication agent of table in embodiment 1-4
IV has excellent extreme pressure and antiwear behavior so that gear-box is in operation process using gearbox lubrication agent of the present invention
Reduce the damage that gear is brought by friction；Have excellent anti-micro- pitting corrosion, the gear that can be effectively prevent inside because of gear-box
Surface micro- point corrosion in metal surface caused by gear material itself, operating condition of gear etc.；Has smaller friction system
Number, not only substantially prolongs the service life of gear, and can save driving force, reaches energy-saving excellent properties.
As can be seen that adding since comparative example 1 is not added with anti-microdot erosion from the property indices of 1 gearbox lubrication agent of table
Add agent, embodies defects of the gearbox lubrication agent V on resisting micro- pitting corrosion, be easy to cause rippling, reduce the work of gear
Make the service life.
From the property indices of 1 gearbox lubrication agent of table as can be seen that since comparative example 2 is not added with reduction gear-box
The friction improver of friction coefficient between internal gear, so the friction obtained in the Test of Friction of gearbox lubrication agent VI
Factor v is larger, and gearbox lubrication agent VI cannot be energy-saving to realize by reducing the friction coefficient operated between gear.
As can be seen that comparative example 3 has selected range of the present invention from the property indices of 1 gearbox lubrication agent of table
Friction improver in addition, gearbox lubrication agent VII friction coefficient is larger, equally cannot be by reducing the friction operated between gear
Coefficient is energy-saving to realize.
From each component that can be seen that in the property indices of 1 gearbox lubrication agent of table in comparative example 4 all in the present invention
Other than the range, the cone penetration numerical value of gearbox lubrication agent VIII is larger, and tooth is be easy to cause after being added in gear-box
Roller box lubricant is leaked out from from gearbox seals or in pilot hole；Extreme pressure and antiwear behavior is poor, cannot be the gear in gear-box
Excellent wear-resistant protection is provided when operating under high loads；Friction coefficient numerical value is larger, and microdot erosion bearing capacity is low, and showing cannot
It is realized by reducing the friction coefficient operated between gear energy-saving and easily causes rippling inside gear-box
Damage.
As can be seen that comparative example 5 has selected range of the present invention from the property indices of 1 gearbox lubrication agent of table
Antioxidant, base oil and extreme pressure anti-wear additives in addition, four ball milling spot diameters, four-ball test index performance are poor, especially in pole
Safe extreme-pressure anti-wear can not be provided using lubricant to protect, so that friction coefficient is increased, cause tooth in the gear-box of ballast load
Surface wear, and cause the erosion agent of anti-microdot that can not effectively prevent the spot corrosion of metal surface.
