Abstract

PURPOSE:To improve the spray penetration of lubricating oil in a bearing, by deciding the direction of an injection hole, jetting the lubricating oil, in relation to rotary speed of a rolling element and allowing the lubricating oil to collide against the rolling element at relative speed with a suitable direction. CONSTITUTION:A lubricating oil injection hole 21 is diagonally drilled from a lubricating oil passage 10 toward the rotary direction (as shown by an arrow head 22) of a bearing 1. The bearing fitted to a rotary shaft 6 is fit mounted to an engine housing 7. The lubricating oil passage 10 is arranged to an adaptor 8 protrusively provided from the housing 7. The rotary shaft 6 is rotated by operation of an engine at its rated maximum speed to reach the rated maximum rotation, then lubricating oil press fed from an oil pump goes into the injection hole 21 from the lubricating oil passage 10, here its speed is increased, thus the oil is injected toward the direction at an angle with a direction 22 of rolling elements 4. The lubricating oil collides against just beside of the rolling element 4.
