Abstract
In a lubrication mechanism including a rotating shaft, the rotating shaft includes an external member and an internal member housed inside the external member, the internal member having an internal space extending in an axial direction, a horizontal hole is formed in the internal member, the horizontal hole for communicating between the internal space and an outer peripheral surface of the internal member, the horizontal hole communicates with a lubrication flow passage for communicating with a prescribed lubrication target portion, and the external member and the internal member are made of materials with a different hardness.
Claims10
A lubrication mechanism comprising a rotating shaft that includes an external member and an internal member, wherein
- the external member has a first internal space inside the external member, and is disposed so that an axial direction of the external member extends along a vertical direction,
- the internal member has a second internal space inside the internal member, and is disposed so that an axial direction of the internal member extends along the vertical direction, the internal member is housed inside the first internal space of the external member, wherein
- a plurality of lateral holes are formed in the internal member, each of the plurality of lateral holes extending in a direction perpendicular to the axial direction and communicating between the second internal space and an outer peripheral surface of the internal member,
- the plurality of lateral holes are arranged at positions spaced apart from each other along the axial direction of the internal member, and each of the plurality of lateral holes communicates with a lubrication flow passage for communicating with a predetermined lubrication target portion, and
- the external member and the internal member are made of materials with different hardnesses.
