Title:
回流の異常な状況を検知できるリニアレール
Document Type and Number:
Japanese Patent JP6806813
Kind Code:
B2
Abstract:
To provide a linear rail.SOLUTION: A linear rail comprises a rail and a slide section. The slide section is attached to the rail so as to form a loading path between the rail and the slide section. The slide section has first and second side caps arranged at both non-loading paths and edge faces opposite to each other. The first side cap has two first circumfluence grooves. The second side cap has a circumfluence member, a flake sealing section and a force sensor. The circumfluence member has two second circumfluence grooves. The loading path, the non-loading paths, the first circumfluence grooves and the second circumfluence grooves integrally form a circulation path where balls roll along the same. The force sensor is arranged between the circumfluence member and the flake sealing section. With aforementioned structural characteristics, the linear rail can determine abnormality in rolling motion of the balls through the first side cap and the second side cap respectively having different stiffness and the force sensor.SELECTED DRAWING: Figure 2
