Title:
POWER TRANSMISSION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2014228065
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve lubricating performance of a bearing around an input shaft of a crank-type transmission unit of a power transmission device for a vehicle.SOLUTION: As a first space S1 accommodating a first bearing 20 and a second space S2 accommodating a second bearing 16 communicate with each other, an input shaft 12 is provided with a lead-in hole 12d for making the second space S2 communicate with the external, and an eccentric cam 18 is provided with a cutout 18e to make the first space S1 communicate with the external, the air including oil mist flowing into the second space S2 from the lead-in hole 12d, flows into the first space S1 to lubricate the first bearing 20 after lubricating the second bearing 16, and is discharged to the external from the cutout 18e. Here, a distance from an axis L to the lead-in hole 12d is shorter than a distance from the axis L to the cutout 18e, pressure difference is generated in the first space S1 and the second space S2 by centrifugal force in accompany with rotations of the input shaft 12 and the eccentric cam 18, so that the air including the oil mist can flow from the lead-in hole 12d toward the cutout 18e by the pressure difference.
