Bearing device

Abstract

Abstract PURPOSE:To prevent an occurrence of damage by burning in the bearing at starting by a method wherein a pair of upper and lower oil vessels are connected by a cooler pipe, and a lubricant is circulated by a centrifugal pump provided on a rotary shaft so that the bearing is dipped into the lubricant when the rotary shaft is being stopped. CONSTITUTION:When the rotary shaft 1 is inoperative, the level of the lubricant is at ''A'' and the ball bearing 4 is dipped into the lubricant 8. Accordingly, when the rotary shaft 1 starts, the ball bearing is lubricated sufficiently not to cause a trouble of burning. When the rotary shaft 1 rotates, the centrifugal pump 6 is operated to feed the lubricant 8 in the lower oil vessel 20 from a low pressure side oil vessel 25 into a high pressure side oil vessel 24. As a result of this, the pressure of the lubricant in the high pressure side oil vessel 24 increases, so that a part of the lubricant enters the upper oil vessel 19. Accordingly, the oil level on the ball bearing 4 side descends, therefore the ball bearing never stirs the lubricant and also the bearing damage can be minimized.
