The property indices of the gearbox lubrication agent prepared by said gear case lubricant compositions I-IX is in table 1:
The property indices of the gearbox lubrication agent prepared by table 1 gearbox lubrication agent composition
As can be seen from the property indices of table 1 gearbox lubrication agent, gearbox lubrication agent I-IV in embodiment 1-4 possesses excellent extreme pressure and antiwear behavior, makes wheel casing that gearbox lubrication agent of the present invention can be utilized in operation process to reduce gear because of the infringement brought that rubs; Possess excellent anti-micro-pitting corrosion, effectively can prevent the micro-point corrosion in metallic surface that the gear surface because of wheel casing inside causes because of the operational condition etc. of the material of gear own, gear; Possess less frictional coefficient, not only substantially prolongs the life-span of gear, and can motivating force be saved, reach energy-saving and cost-reducing excellent properties.
As can be seen from the property indices of table 1 gearbox lubrication agent, because comparative example 1 does not add anti-micro-spot corrosion additive, embody the defect of gearbox lubrication agent V on anti-micro-pitting corrosion, easily cause rippling, reduce the working life of gear.
As can be seen from the property indices of table 1 gearbox lubrication agent, because comparative example 2 does not add the friction improver of the frictional coefficient reduced between wheel casing internal gear, so the frictional coefficient numerical value obtained in the Test of Friction of gearbox lubrication agent VI is comparatively large, gearbox lubrication agent VI does not realize saving energy and reduce the cost by reducing the frictional coefficient operated between gear.
As can be seen from the property indices of table 1 gearbox lubrication agent, comparative example 3 have selected the friction improver beyond scope of the present invention, gearbox lubrication agent VII frictional coefficient is comparatively large, does not realize saving energy and reduce the cost equally by reducing the frictional coefficient operated between gear.
As can be seen from the property indices of table 1 gearbox lubrication agent, each component in comparative example 4 is all beyond scope of the present invention, the cone penetration numerical value of gearbox lubrication agent VIII is comparatively large, easily causes gearbox lubrication agent to spill from gearbox seals or pilot hole after adding in wheel casing; Extreme pressure and antiwear behavior is poor, provides excellent wear-resistant protection when can not operate under high loads for the gear in wheel casing; Frictional coefficient numerical value is comparatively large, and micro-spot corrosion supporting capacity is low, shows not realize saving energy and reduce the cost and the infringement being easy to cause the inner rippling of wheel casing by reducing the frictional coefficient operated between gear.
As can be seen from the property indices of table 1 gearbox lubrication agent; comparative example 5 have selected oxidation inhibitor, base oil and extreme pressure anti-wear additives beyond scope of the present invention; its four ball millings spot diameter, four-ball test index poor-performing; in the wheel casing of extreme pressure heavy loading, make with lubricator cannot provide safe extreme-pressure anti-wear protection especially; frictional coefficient is increased; cause tooth surface abrasion, and cause anti-micro-spot corrosion agent effectively cannot prevent the spot corrosion of metallic surface.
