WIPO Patent Application WO/2015/098896
Kind Code:
A1
Abstract:
The present invention pertains to a bearing device which is more compact than the prior art and does not require complicated machining, and with which lubricating oil can be supplied in an appropriate amount and in a stable manner to a bearing, even when the peripheral speed of a rotary shaft is increased to a high speed. In addition, the present invention pertains to a pump equipped with such a bearing device. The bearing device is equipped with: a bearing (32) that receives the load of a rotary shaft (1); a lubricating oil reservoir (10) arranged below the bearing (32); an oil disk (11) that is affixed to and rotates integrally with the rotary shaft (1), thereby scooping up the lubricating oil stored in the lubricating oil reservoir (10); a lubricating oil passage (17) extending to the bearing (32); and a guide casing (15) that guides the lubricating oil scooped up by the oil disk (11) to the lubricating oil passage (17). The guide casing (15) has an inner surface that faces the side surface and the outer peripheral surface of the oil disk (11).
