Abstract:
A bearing device includes a thrust bearing. The thrust bearing has a bearing surface in a half-split ring shape, and a plurality of oil grooves formed to cross the bearing surface from an inner circumferential side to an outer circumferential side. Further, the thrust bearing includes a first thrust bearing that is disposed on a side surface facing a side of a transmission, and a second thrust bearing that is disposed on a side surface facing an opposite side to the transmission. In the first thrust bearing, a bearing surface between the plurality of oil grooves is configured by including a taper surface formed so that a wall thickness becomes thicker toward a rotation direction of the crankshaft. Further, in the second thrust bearing, a bearing surface between the plurality of oil grooves is configured by a plane in which a wall thickness is constant.

Claim (Index 1):
A bearing device for a crankshaft, which supports the crankshaft having one end to which a transmission is connected,\n the bearing device comprising: a bearing support portion that has a bearing hole penetrating between two side surfaces facing each other, and supports a journal of the crankshaft by the bearing hole; and a thrust bearing that has a bearing surface in a half-split ring shape, and a plurality of oil grooves formed to cross the bearing surface from an inner circumferential side to an outer circumferential side, and receives a force in an axial direction of the crankshaft by being disposed at a circumferential edge of the bearing hole in each of the two side surfaces, wherein the thrust bearing includes a first thrust bearing that is disposed on a side surface facing a side of the transmission out of the two side surfaces, and a second thrust bearing that is disposed on a side surface facing an opposite side from the transmission out of the two side surfaces, in the first thrust bearing, a bearing surface between the plurality of oil grooves is configured by including a taper surface formed so that a wall thickness becomes thicker toward a rotation direction of the crankshaft, and in the second thrust bearing, a bearing surface between the plurality of oil grooves is configured by a plane in which a wall thickness is constant.
