リニアガイドにおける電食とその損傷形態

（1.0 A 以下の場合）

抄録

In recent years, due to the demand for energy conservation, rolling guides that can be driven with less force are being replaced. Among these, a mechanical element called a linear guide is used for linear motion guidance. This linear guide has a short history compared to rolling bearings used for rotational guides, and much remains unknown. Future research is expected. In this study, we applied voltages of 0.1 A, 0.5 A, and 1.0 A to the rail side of the linear guide and positive voltage to the carriage side, respectively, and operated for 1000 h. As a result, under all current conditions, there were no discharge marks on the rail, discharge marks were formed on the rolling surface on the carriage side, and discharge marks were formed all around the ball. Furthermore, the area where discharge marks are formed on the carriage side becomes wider as the applied current increases, and at an applied current of 0.5 A, discharge marks with a striped pattern at the pitch of the rolling elements were formed.
