Title:
LUBRICATING OIL SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/098978
Kind Code:
A1
Abstract:
A lubricating oil supply device (5) that can be reduced in size while sufficiently ensuring a housing space for an occluding body. The lubricating oil supply device (5) is mounted to a slide member (2) that engages with a raceway shaft (4) via a rolling body (3). The lubricating oil supply device (5) supplies lubricating oil to a rolling body rolling surface (4a) of the raceway shaft in association with relative movement between the slide member and the raceway shaft. The lubricating oil supply device (5) is provided with: an occluding body (51), which includes multiple gaps therein and which holds lubricating oil in those gaps; a casing (50), which has a housing chamber (50c) of the occluding body and an opening (55) that faces the raceway shaft and opens up the housing chamber, and which is fixed to the slide member; and a coated body (52), which is disposed in the opening of the casing in contact with the raceway shaft and to which lubricating oil is supplied from the occluding body. A notch portion (57) is arranged corresponding to the opening of the casing in the occluding body. The coated body has a lower porosity than the occluding body, and is sandwiched by the notch portion of the occluding body, thereby expanding the notch portion.
