Self-lubricating bearing for hydraulic steel gate

Abstract

The invention discloses a self-lubricating bearing for a hydraulic steel gate, and the self-lubricating bearing comprises a tubular base body which is arranged on the neck of a shaft in a cup joint way, wherein a plurality of pre-openings are distributed on the tubular base body, each pre-opening is sequentially provided with a solid lubricant and a thrust spring from inside to outside, the solid lubricant is in clearance fit with the pre-openings, the tubular base body is externally provided with a bearing bush type fixed shell fixed on the tubular base body by sunk screws, and the inner wall of the bearing bush type fixed shell leans against the outer ends of the thrust springs. The lubricating mode provided by the self-lubricating bearing is active lubricating, i.e., the solid lubricant is in clearance fit with the pre-openings of the tubular base body, the pre-openings are gradually exposed under the effect of the thrust springs, and the pre-openings can be well contacted with the neck of the shaft, so that the lubricant can be continuously provided due to the 'active wear' of the solid lubricant, therefore, the wear of the base body can be reduced, and the service life of the bearing can be prolonged; and when lubricating blocks taken as the solid lubricant are exhausted, the self-lubricating bearing can be continuously used only by changing the lubricating blocks, so that the maintenance cost can be reduced.

Description

technical field [0001] The present invention relates to a bearing structure, in particular to a bearing structure related to lubrication. Background technique [0002] With the construction of some high dams in my country, the water pressure on the working gates and maintenance gates of the bottom hole is increasing, and as the structure that transmits these water pressures to the dam body, the walking support and arc shape The rotating mechanism such as the rotating hinge of the steel gate mainly works under the condition of low speed and heavy load. This working condition determines that the sliding bearings of these rotating parts cannot form a complete and dense oil film. If the traditional grease lubrication is applied, the sliding bearing will work under the condition of boundary friction, which will cause rapid wear and even seizure between the journal and the bearing. Since ordinary liquid lubricated bearings cannot meet the requirements of this special working condi...

Problems solved by technology

[0006] The present invention aims to solve the technical problem that the solid lubricant embedded in the substrate cannot be "actively worn" to continuously provide lubricant. It provides a self-lubricating bearing for hydraulic steel gates, which can make the substrate of the self-lubricating bearing itself The material does not wear or wears very little, but allows the solid lubricant itself to "actively wear" to continuously provide lubricant to meet the lubrication needs
