Abstract
A lubricant supply device for a linear guide apparatus is configured to include an end cap 5, and a container 7 retaining lubricant and disposed adjacent to the end cap 5. The end cap 5 is formed with a through-hole 16 extending toward the container 7 from a direction change path 5a. The container 7 is formed with an aperture communicating with the through-hole 16 of the end cap 5. The lubricant is supplied into the direction change path 5a via the aperture of the container 7 and the through-hole 16 of the end cap 5. The slider can be thereby lubricated while preventing damage to a rolling element and the direction change path of the end cap.
Claims7
A lubricant supply device for a linear guide apparatus, comprising:
- an end cap disposed at an end portion of a slider in a longitudinal direction, and having a direction change path for changing over a rolling direction of rolling elements within the slider;
- and
- a container retaining lubricant and disposed adjacent to the end cap,
- the end cap being formed with a through-hole extending toward the container from the direction change path,
- the container being formed with an aperture communicating with the through-hole of the end cap,
- the lubricant being supplied into the direction change path via the through-hole of the end cap,
- wherein the container retains a lubricating member having a protruded portion composed of porous molding impregnated with the lubricant,
- the protruded portion of the lubricating member protrudes from the aperture of the container, is inserted into the through-hole of the end cap and is exposed into the direction change path, and
- a front end of the protruded portion of the lubricating member forms a curved surface along a rolling groove of the direction change path.
