Description

【発明の名称】グリース組成物及び工作機械の主軸支持用転がり軸受 Patent application title: Grease composition and rolling bearing for supporting a spindle of a machine tool

【０００１】
【発明の属する技術分野】
本発明は、例えば旋盤、ボール盤、中ぐり盤、フライス盤、研削盤、ホーニング盤、超仕上盤、ラップ盤等で代表される、高速で摺動、回転する工作機械の主軸支持部に組み込まれる転がり軸受、並びに前記軸受に封入されるグリース組成物に関する。[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is, for example, a lathe, a drilling machine, a boring machine, a milling machine, a grinding machine, a honing machine, a super-finishing machine, a rolling machine incorporated in a spindle support portion of a machine tool that slides and rotates at a high speed, such as a lapping machine. The present invention relates to a bearing and a grease composition sealed in the bearing .

【０００５】
【発明が解決しようとする課題】
本発明はこのような状況に鑑みてなされたものであり、高速回転に充分に対応でき、工作機械のコンパクト化や運転経費の削減を可能にするグリース組成物、並びに前記グリース組成物を封入してなる工作機械の主軸支持用転がり軸受を提供することを目的とする。[0005]
[Problems to be solved by the invention]
The present invention has been made in view of such a situation, is capable of sufficiently coping with high-speed rotation, a grease composition capable of reducing the size and operating costs of a machine tool, and encapsulating the grease composition. It is an object of the present invention to provide a rolling bearing for supporting a main shaft of a machine tool .

【０００６】
【課題を解決するための手段】
本発明に係る上記目的は、工作機械の主軸支持用転がり軸受に封入されるグリース組成物であって、モノスルフィド化合物、ジスルフィド化合物、スルホキシド化合物及びチオールスルフィネート化合物から選ばれる少なくとも１種を、グリース組成物全量に対して、イオウ換算で０．００１重量％以上５重量％以下の割合で含有することを特徴とするグリース組成物、及び前記グリース組成物を封入してなることを特徴とする工作機械の主軸支持用転がり軸受により達成される。[0006]
[Means for Solving the Problems]
The above object according to the present invention is a grease composition sealed in a main shaft supporting rolling bearing of a machine tool, a monosulfide compound, a disulfide compound, at least one selected from a sulfoxide compound and a thiol sulfinate compound, A grease composition characterized by being contained at a ratio of 0.001% by weight or more and 5% by weight or less in terms of sulfur with respect to the total amount of the grease composition , and the grease composition being encapsulated. This is achieved by a rolling bearing for supporting a spindle of a machine tool .
