High-power high-speed sliding bearing

Abstract

The utility model discloses a high-power high-speed sliding bearing, and overcomes the defect in the conventional high-power high-speed sliding bearing that the lubricating oil carried by an oil slinger cannot enter the gap between a shaft and a bearing bush for lubrication. An oil baffle plate corresponding to an oil slinger and positioned on the inner side of the oil slinger is arranged on a lower bearing bush and on one side opposite to the rotation direction of a shaft, and lubricating oil carried to the shaft by the oil slinger when the shaft rotates is collected on the edge of the lower bearing bush after being blocked by the oil baffle plate when being thrown under the action of centrifugal force, and can well enter the gap between the shaft and the bearing bush for lubrication, so that the lubricating effect is improved; an axially extending oil wedge groove is formed at the abutting joint between the edges of the inner surfaces of an upper bearing bush and the lower bearing bush, and has the effect of guiding the collected lubricating oil to enter in the gap between the shaft and the bearing bush, so as to further improve the lubricating effect; and drain channels communicated with the oil wedge groove and an oil chamber are manufactured at two ends of the oil wedge groove, and the lubricating oil can enter the lubricating part from the oil wedge groove and then is drained through the drain tanks during the lubricating process, so as to form cycling regeneration.

Description

technical field [0001] The invention belongs to sliding bearings, in particular to a high-power and high-speed sliding bearing with large bearing load, small operating temperature rise and short working temperature stabilization time. Background technique [0002] The applicant's invention patent No. ZL201020576782.0 discloses a technical solution of "high-power high-speed sliding bearing" (authorized announcement number: CN201818650U), the upper bearing bush and the lower bearing bush are inserted on the joint surface of the two by positioning pins The positioning of the two is realized in the positioning hole on the top, and the bolts passing through the joint surface of the two are connected and fastened to form a bearing bush assembly; the upper bearing body and the lower bearing body are also positioned by positioning pins and fastened by bolts. The bearing body and the lower bearing body are provided with an oil chamber; the bearing bush assembly is assembled in the up...
