Linear guide rail

Abstract

The invention provides a linear guide rail. The linear guide rail comprises a lubricating oil box; a dustproof piece is arranged on one side of the lubricating oil box; a bracket is arranged above themiddle part of the other side of the lubricating oil box; sleeves sleeve two ends of the other side of the lubricating oil box; slide blocks are arranged at the other ends of the bracket and the sleeves; lubricating pieces are arranged on one sides of the slide blocks; ball chains and guide rails are arranged in the slide blocks; four ball chains are provided and inserted in the slide blocks; andoil storage boxes are arranged on the other sides of the slide blocks. Through the ball chains, the slide blocks enables steel balls to circulate through maintenance by the ball chains, so that the friction between the steel balls is eliminated, and the steel balls are arranged at equal intervals to circularly move; in space between the steel ball circulating parts and the ball chains, lubricating grease stored in the lubricating oil boxes and lubricating pieces is applied to the surfaces of the steel balls along with rotation of the steel balls, so that the surfaces of the steel balls are always lubricated by oil films; and the linear guide rail is suitable for the field of mechanical automation, and achieves excellent development prospect.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, in particular to a linear guide rail. Background technique [0002] Mechanical automation refers to the process in which machines or devices are automatically operated or controlled according to predetermined procedures or instructions without human intervention, and mechanical automation is the process in which machines or devices are automatically controlled by mechanical means. Linear guides are included in automation equipment. [0003] Linear guides are mainly used in mechanical structures with relatively high precision requirements. There is no intermediate medium between the moving element and the fixed element of the linear guide, but rolling steel balls are used. However, the existing linear guides will rub when the steel balls are in operation. Noise is produced, and the friction between each other generates heat, causing serious wear and tear, resulting in the need for c...
