<p>The present invention relates to a lubricating oil supply structure of an idle gear for transmitting torque, including the idle gear (30) arranged between a driving gear (10) and a driven gear (20) and arranging contact lines engaged with the gears (10, 20) to not be parallel and having an equivalent load point (31), on which a load caused by the transmission of the torque by the gears (10, 20) is applied, on one side; a fixed shaft (40) penetrated through a central axis of the idle gear (30), supporting the axial rotation of the idle gear (30), and including a passage (41) connected to the outer periphery on the one side; a bearing (50) arranged between the fixed shaft (40) and the inner circumference of the idle gear (30), integrally rotating with the idle gear (30) around the axis, and forming an oil film (55) between the fixed shaft (40) and the bearing (50); and a lubricating oil supply unit (42) for sufficiently supplying lubricating oil passing through the passage (41) to the oil film (55) between the fixed shaft (40) and the bearing (50). The lubricating oil supply structure of the idle gear for transmitting torque basically enables the smooth supply of the lubricating oil for forming the oil film and the improvement of the performance of lubricating the fixed shaft and bearing at the same time by forming the lubricating oil supply unit for sufficiently supplying the lubricating oil to the oil film between the fixed shaft and bearing, especially at the position away from the equivalent load point of the idle gear, whereupon an effect such as the improvement of the reliability of a lubricating device is obtained.</p> |
