Description

The present invention relates to a lubrication holding device used in a linear system, and in particular, using a principle of magnetic force, even if a linear guideway is operated and a lubricant-containing element is worn, the lubricant-containing element rails the lubricant. The present invention relates to a lubrication holding device that can be continuously supplied to the ball groove.

  At present, commercially available linear guideways have a lubricating oil tank with a sponge containing lubricating oil installed at both ends of the block. There are three types of new products that have improved on the above-mentioned problems because a gap is generated when rubbed, and the lubricating oil in the sponge cannot reach the rail due to the gap.

  One of them is that a spring mechanism is installed in the lubricating oil tank, and a sponge containing lubricating oil is pushed by the spring mechanism to make effective contact with the rail. The disadvantage is that the structure is complicated and the assembly is extremely inconvenient, and The spring's elasticity becomes weaker as it wears, and when used for a long period of time, the spring is elastically fatigued, causing the pressure on the sponge to be unstable (US Pat. No. 5,547,285).

  Second, a U-shaped spring piece is mounted in the lubricating oil tank, and the sponge is pressed from the outside to the inside by this U-shaped spring piece, thereby effectively bringing the sponge containing the lubricating oil into contact with the rail. Disadvantages are that the pressing force becomes weaker as the sponge is worn, and the spring piece has a problem of elastic fatigue (US Pat. No. 6,667,764).

Third, a rubber having elasticity is installed in the lubricating oil tank, and the sponge is pressed from the outside to the inside by the rubber, thereby effectively bringing the sponge containing the lubricating oil into contact with the rail. The pressing force becomes weaker as the sponge is worn, and the spring piece also has a problem of elastic fatigue, and the weather resistance of the rubber is not good, so it is easily altered (US Pat. No. 6,667,764).
