Problems solved by technology

However, since traction oil is liquid, oxygen is dissolved in the oil, so there are problems in extending the life of the mechanical system such as oxidative deterioration, evaporation due to temperature rise, and leakage from the seal.
On the other hand, compared with the case of using lubricating oil, the system does not need to adopt a closed structure, but the oil and thickener are separated at high temperature, and the once separated oil and thickener will not recover, which may cause damage to the sliding part. Insufficient oil to perform initial performance or separated oil contaminates the surrounding area

Embodiment

[0058] Hereinafter, the present invention will be described in more detail using examples, but the present invention is not limited thereto.

[0059] [Liquid base oil]

[0060] In order to prepare the lubricant compositions used in Examples and Comparative Examples, the following three types of liquid base oils were used.

[0061] Base oil A: Synthetic naphthalene (Techtrac M3Conc manufactured by Techchem Corporation)

[0062]Base oil B: soft alkylbenzene (kinematic viscosity (40°C): 32mm 2 / s)

[0063] Base oil C: α-olefin oligomer (SHF-400 manufactured by Mobil Corporation)

[0064] Table 1 shows the physical properties of these three liquid base oils. In addition, these liquid lubricating base oils contain predetermined amounts of additives such as antioxidants and anti-wear agents in advance, and have basic properties (anti-oxidation, anti-wear, etc.) as lubricating oils.

Abstract

The invention provides a lubricant composition in a semisolid state at constant temperature displaying highly dynamic friction coefficient beneficial to transmission and coating little oil solution on a lubricate slippery section with high lubricity in a thin film state and a lubrication system using the same. The lubricant composition comprises hydrocarbon-based oil of 10 mass% to 98.9 mass% with %Cp less than 70, at least one of organic phosphate and polysiloxane, alkaline-earth metal salts of 1 mass% to 20 mass% and amide compound of 0.1 mass% to 89 mass% as well as lubricant composition in semisolid state at constant temperature. The lubricant composition is used for the lubrication system for transmission of key mechanisms.

Description

technical field [0001] The present invention relates to a semi-solid lubricant composition at normal temperature, and particularly relates to a lubricant composition having good wear resistance and extreme pressure properties and a high coefficient of dynamic friction. The invention also relates to the use of the lubricant composition in a lubrication system for transmission key mechanisms. Background technique [0002] In recent years, among various industrial technologies, multifunctionality, high performance, environmental response, energy saving, and long life have become important key technologies. Examples of environmental issues include reduction of carbon dioxide emissions, power saving, energy saving, effective use of resources, and the like. Therefore, various mechanical systems such as small precision machinery, industrial machinery, and transportation systems are not only improved to be environmentally friendly, but also have features such as longer life, improv...
