Motion guide device, table apparatus, and damping method for motion guide device |
摘要 |
A motion guide device that has a novel damping structure different from the conventional damping structure is provided. The present invention comprises a raceway member (1) having a rolling-element rolling part (1a); a moving member (2) having a loaded rolling-element rolling part (2a) facing the rolling-element rolling part (1a) and being allowed to make a linear or curved movement relatively to the raceway member (1); and a plurality of rolling elements (3) intervening between the rolling-element rolling part (1a) of the raceway member (1) and the loaded rolling-element rolling part (2a) of the moving part (2). A gap (16) between the raceway member (1) and the moving member (2) is filled with a layer of oil contacting the raceway member (1) and the moving member (2). Viscosity resistance of the oil is utilized to apply a braking force to the moving member (2) or the raceway member (1) in proportion to a speed. |
