BEARING STRUCTURE
Document Type and Number:
Japanese Patent JPH06294413
Kind Code:
A
Abstract:

PURPOSE: To set an adequate amount of oil-relief, improve the startability at low temperatures, and reduce vibration and noise.

CONSTITUTION: The cross-sectional shape of bearing members 21, 22, 23, 24 is made truly round, and the cross-sectional shape of journals J1, J2, J3, J4 is made in a specified elliptic shape. These journals J1, J2, J3, J4 are respectively journalled to the bearing members 21, 22, 23, 24 to form oil-reliefs 31, 32, 33, 34 respectively having a specified amount (d) of oil-relief between the journals J1, J2, J3, J4 and the bearing members 21, 22, 23, 24 respectively. The relative positions between the journals J1 to J4 and the bearing members 21 to 24 are set so that the major axes of the elliptic cross-section of the journals J1, J2, J3, J4 are located in the direction of loads which are applied from either of the respective journals and the bearing members of the journals to the other side.
