  • Motion guiding device and lubrication path component used in motion guiding device
    Patent number: 11905990
    Abstract: A motion guiding device includes a supporting body and a moving body. The moving body includes a moving body main body, a cover body and a circulation component. The cover body includes a first lubrication groove. The motion guiding device is further provided with a lubrication path component, the lubrication path component including a second lubrication groove having a cross-sectional area less than that of the first lubrication groove. When a lubricating oil is used as the lubricant, the lubricant is supplied by a lubricating oil lubrication path formed by the first lubrication groove and the second lubrication groove. In this way, in the motion guiding device, the lubrication path may be widened when the lubricating grease is used to lubricate, while the lubrication path may be narrowed when the lubricating oil is used to lubricate, so that a good lubrication may be easily achieved.
