Abstract
A lubricating device for a linear guideway, used at either side of the slide block of a linear guideway, comprises: a housing, oil-containing member, magnets and metallic magnetic members. Using a magnetic force to push the oil-containing member against the rail, the magnetic force will not fatigue but will increase with the reduction in distance between the magnets and the metallic magnetic members, therefore, the oil-containing member can be kept in a good contact with the rolling passage of the rail, and the lubricating oil can be continuously transmitted from the oil-containing member to the surface of the rail, thus lubricating the linear guideway automatically without disassembling it.
