Gear Oil Additive Good Oxidation Stability And Thermal Stability Jul 13, 2017

Gear Oil Additive transmission is an important form of mechanical transmission. There are a variety of transmission methods, more commonly used are: mechanical transmission, gas compression drive, electric drive and hydraulic drive. Although the mechanical transmission exists: the speed is difficult, the operation is not easy, the structure is complex, the movement inertia big, there are pulse and other shortcomings, but as the traditional transmission mode has its irreplaceable position, so far in the industrial machinery equipment is still indispensable。

Industrial Gear Oil Additive oil, according to ISO 6743.6 GB / T 7631.7 industrial Gear Oil Additive lubricant classification standards: industrial Gear Oil Additive oil for Gear Oil Additive or turbine worm lubrication, product symbol CK, in which the role of Gear Oil Additive transmission is to change the number of rotating parts (Speed), the transmission of the turbine worm is to change the direction of the rotating parts.

The Gear Oil Additive part is divided into closed Gear Oil Additive oil and open Gear Oil Additive oil. Closed Gear Oil Additive oil with closed Gear Oil Additive box, respectively, light load CKB, the load CKC, heavy load CKD, synthetic heavy duty CKT, synthetic light load anti-friction CKS and other models. Open Gear Oil Additive oil without Gear Oil Additive box and semi-immersion open type, respectively, in the temperature light load CKH / CKJ, high temperature and heavy load CKL.

Turbine worm parts have non-extreme pressure CKE and extreme pressure CKE (EP).

1, with different occasions. The former is used for fixed industrial Gear Oil Additivebox lubrication, which is used to move the vehicle Gear Oil Additivebox to lubricate. In other words, the latter with the oil environment temperature changes, but also the flow of equipment, high and low temperature requirements are relatively high. So the vehicle Gear Oil Additive oil to be multi-level and single-level points.

2, the load, heavy load of the vehicle Gear Oil Additive is generally hyperbolic Gear Oil Additive, compared with the often cylindrical or tapered industrial Gear Oil Additive bearing requirements are higher. Therefore, the load capacity of medium load vehicle Gear Oil Additive oil is equivalent to heavy load industrial Gear Oil Additive oil. So the equivalent viscosity of the medium load of the vehicle Gear Oil Additive oil can replace the heavy load industrial Gear Oil Additive oil such as 90 GL-4 or 85W / 90 GL-4 can replace 220CKD.

3, the vehicle Gear Oil Additive oil viscosity grade is according to the American Society of Automotive Engineers SAE classification, measured at 100 ℃ when the kinematic viscosity. The industrial Gear Oil Additive oil is in accordance with the provisions of the International Organization for Standardization ISO classification, measured at 40 ℃ when the kinematic viscosity. So the substitution must be converted.

4, classification, ISO only provides the industrial Gear Oil Additive oil classification symbol C, and no special provisions of the vehicle Gear Oil Additive oil group symbol. China uses API to use GL-3, GL-4, GL-5 classification. This relationship is described in Appendix B of the Industrial Gear Oil Additive Oil Standard.

3 difference between industrial Gear Oil Additive oil and vehicle Gear Oil Additive oil

1, with different occasions. The former is used for fixed industrial Gear Oil Additivebox lubrication, which is used to move the vehicle Gear Oil Additivebox to lubricate. In other words, the latter with the oil environment temperature changes, but also the flow of equipment, high and low temperature requirements are relatively high. So the vehicle Gear Oil Additive oil to be multi-level and single-level points.

2, the load, heavy load of the vehicle Gear Oil Additive is generally hyperbolic Gear Oil Additive, compared with the often cylindrical or tapered industrial Gear Oil Additive bearing requirements are higher. Therefore, the load capacity of medium load vehicle Gear Oil Additive oil is equivalent to heavy load industrial Gear Oil Additive oil. So the medium of gravity medium load medium Gear Oil Additive oil can replace heavy duty industrial Gear Oil Additive oil such as 90 GL-4 or 85W / 90 GL-4 can replace 220 CKD.

3, the vehicle Gear Oil Additive oil viscosity grade is according to the American Society of Automotive Engineers SAE classification, measured at 100 ℃ when the kinematic viscosity. The industrial Gear Oil Additive oil is in accordance with the provisions of the International Organization for Standardization ISO classification, measured at 40 ℃ when the kinematic viscosity. So the substitution must be converted.

4, classification, ISO only provides the industrial Gear Oil Additive oil classification symbol C, and no special provisions of the vehicle Gear Oil Additive oil group symbol. China uses API to use GL-3, GL-4, GL-5 classification. This relationship is described in Appendix B of the Industrial Gear Oil Additive Oil Standard.

In addition, the industrial Gear Oil Additive oil in the friction and wear of the special assessment means are mainly reflected in: four-ball test, Timken test and Gear Oil Additive test. And the vehicle Gear Oil Additive oil must be assessed by CRC L-37 (high speed low torque, low speed high torque) and CRC L42 (high speed impact load) to assess its carrying capacity.

4 characteristics of industrial Gear Oil Additive oil

1, the appropriate viscosity and good viscosity temperature. Viscosity is the most basic nature of Gear Oil Additive oil. The formation of fluid dynamic membrane and elastic fluid lubricating film is closely related to the viscosity of Gear Oil Additive oil, the viscosity of oil is large, the oil film is thick and the anti-load capacity is large. Viscosity is good, the viscosity changes with the temperature changes in the degree of small. Oil film thickness changes are also small.

2, enough extreme pressure anti-wear. Extremely strong wear resistance of the oil in the Gear Oil Additive mechanism at high speed, low speed heavy load or impact load, the formation of boundary adsorption film or chemical reaction film. Can prevent tooth surface wear, abrasion and gluing.

3, good oxidation stability and thermal stability. Gear Oil Additive oil work, and air, metal, impurities in contact, in the case of high temperature, easy to oxidative deterioration, so that oil life shortened.
