Description
本発明は、潤滑油組成物に関し、さらに詳しくは、耐焼付性及び耐疲労性に優れる上、酸化試験でスラッジの生成が抑制された潤滑油組成物であって、特に風力発電用増速機油組成物として好適な潤滑油組成物に関する。 The present invention relates to a lubricating oil composition, and more particularly, is a lubricating oil composition that is excellent in seizure resistance and fatigue resistance, and in which sludge generation is suppressed in an oxidation test, and particularly a speed increasing oil for wind power generation The present invention relates to a lubricating oil composition suitable as a composition.
近年の環境負荷軽減及び化石燃料の枯渇などの観点から、再生可能なエネルギーを活用した風力発電は、今後さらなる需要の増加が予想されている。
風力を利用した風力発電は、風を受けて回転するプロペラその他のロータを
使用して風の運動エネルギーを動力に変換し、この動力で発電機を駆動して電気エネルギーに変換する。
このような風力発電においては、ロータの回転速度が遅いため、発電機の発電効率を考慮し、増速機が使用される。この増速機としては、様々なものが知られているが、その中で遊星歯車式動力伝達装置が多用されている。
このような遊星歯車式動力伝達装置などに使用される風力発電用増速機油組成物に対しては、優れた耐焼付性及び耐ＦＺＧマイクロピッチング性等の耐疲労性を有し、かつ酸化安定性試験において、スラッジの発生が少ないことが要求される。
風力発電用増速機に用いられる潤滑油組成物としては、例えば（ａ）硫黄化合物を含む極圧化合物、（ｂ）ヒドロカルビルアミン化合物とアルキルホスホロチオエート化合物との混合物、（ｃ）摩擦調整用化合物及び（ｄ）基油を含有する潤滑油組成物が提案されている（例えば、特許文献１参照）。
しかしながら、この潤滑油組成物は、風力発電用増速機油組成物に要求される前記要求性能の全てを十分に満足しているとは言えない。From the viewpoint of reducing environmental impacts in recent years and the depletion of fossil fuels, wind power generation using renewable energy is expected to increase further in the future.
Wind power generation using wind power uses a propeller or other rotor that rotates in response to wind to convert wind kinetic energy into power, which drives the generator to convert it into electrical energy.
In such wind power generation, since the rotational speed of the rotor is slow, a speed increaser is used in consideration of the power generation efficiency of the generator. Various types of speed increasers are known, and planetary gear type power transmission devices are frequently used.
It has excellent seizure resistance and fatigue resistance such as FZG micropitting resistance, and oxidation stability for the speed increasing gear oil composition used for such planetary gear type power transmission devices. In the property test, the generation of sludge is required to be small.
Examples of the lubricating oil composition used in the wind power booster include (a) an extreme pressure compound containing a sulfur compound, (b) a mixture of a hydrocarbylamine compound and an alkyl phosphorothioate compound, (c) a compound for friction adjustment, and (D) A lubricating oil composition containing a base oil has been proposed (see, for example, Patent Document 1).
However, it cannot be said that this lubricating oil composition sufficiently satisfies all of the required performances required for the wind power booster oil composition.
本発明は、このような状況下で、耐焼付性及び耐疲労性に優れる上、酸化試験でスラッジの生成が抑制された風力発電用増速機油組成物として好適な潤滑油組成物を提供することを目的とするものである。 Under such circumstances, the present invention provides a lubricating oil composition that is suitable as a speed-up gear oil composition for wind power generation that is excellent in seizure resistance and fatigue resistance and in which sludge generation is suppressed in an oxidation test. It is for the purpose.

実施例１〜８及び比較例１〜７
第１表に示す配合組成の潤滑油組成物を調製し、該組成物の諸特性を求めた。結果を第１表に示す。Examples 1-8 and Comparative Examples 1-7
A lubricating oil composition having the composition shown in Table 1 was prepared, and various properties of the composition were determined. The results are shown in Table 1.
第１表から分かるように、実施例１〜５は、チムケン試験、ＦＺＧ焼付き試験、ＦＺＧマイクロピッチンク試験及びインディアナ酸化試験のいずれも合格である。実施例６はポリオール部分エステルが添加されておらず、また実施例7はポリオール完全エステルが添加されており、いずれもインディアナ酸化試験において、スラッジの生成が若干多い。実施例８は酸性リン酸エステルとして、アルキル基の炭素数が８である酸性リン酸２−エチルヘキシルエステルが用いられており、インディアナ酸化試験において、スラッジの生成が少し多くなっている。
比較例１〜６は、いずれも本発明における規定要件のいずれかが外れており、したがって、性能が実施例のものに比べて劣る。
市販品(比較例７)は、インディアナ酸化試験において、スラッジの生成が著しく多い。As can be seen from Table 1, in Examples 1 to 5, all of the Timken test, FZG seizure test, FZG micropitch test, and Indiana oxidation test passed. In Example 6, the polyol partial ester was not added, and in Example 7, the polyol complete ester was added. In both cases, sludge generation was slightly higher in the Indiana oxidation test. In Example 8, acidic 2-ethylhexyl phosphate having an alkyl group having 8 carbon atoms is used as the acidic phosphate, and sludge generation is slightly increased in the Indiana oxidation test.
Each of Comparative Examples 1 to 6 is out of any of the defined requirements in the present invention, and therefore the performance is inferior to that of the example.
The commercially available product (Comparative Example 7) has significantly more sludge produced in the Indiana oxidation test.
本発明の潤滑油組成物は、耐焼付性及び耐ＦＺＧマイクロピッチング性等の耐疲労性に優れる上、酸化試験でスラッジの生成が少なく、歯車油、軸受油などの各種潤滑油、特に風力発電機に用いられる遊星歯車式動力伝達装置などの増速機に使用される潤滑油として好適である。 The lubricating oil composition of the present invention is excellent in seizure resistance and FZG micropitting resistance and other fatigue resistance, and generates little sludge in an oxidation test, and various lubricating oils such as gear oil and bearing oil, especially wind power generation. It is suitable as a lubricating oil used in a speed increaser such as a planetary gear type power transmission device used in a machine.
