Problems solved by technology

When the excavator is working, the horse head does not rotate, and the bucket ear and the bucket pin rotate together. Severe dry friction will inevitably occur between the horse head and the flat washer, and between the bucket ear and the flat washer, resulting in serious wear of the horse head and the bucket ear. Severe dry friction is bound to consume a lot of engine power

Abstract

The invention discloses a thrust ball bearing with the good sealing performance and an application thereof. The thrust ball bearing comprises a flange-shaped base and a flange-shaped shaft ring, wherein the flange-shaped base comprises a base flange plate and a base flange tube, and the flange-shaped shaft ring comprises a shaft ring flange plate and a shaft ring flange tube; the base flange tubeis provided with a groove, and the groove is used for dividing the base flange tube into a base flange inner tube and a base flange outer tube, and a bearing base is installed at the bottom part of the groove; two ends of retainer rolling bodies are arranged in a bearing base rolling way and a shaft ring flange tube end surface rolling way respectively; oil permeation holes are formed in the baseflange outer tube, a left reinforcing rib and a right reinforcing rib are arranged on the base flange outer tube, and an outer sleeve is arranged on the outer periphery of the base flange outer tube;and a cavity formed among the outer wall of the base flange outer tube, the inner wall of the outer sleeve, an end plate and the inner wall of the base flange plate is an oil storage cavity. The invention further discloses the application of the thrust ball bearing on an excavator. According to the thrust ball bearing with the good sealing performance and the application thereof, the oil storage cavity is adopted, so that the oil storage capacity is increased, the lubricating effect is good, the sealing performance is good, and maintenance is not needed in years.

Description

technical field [0001] The invention relates to a thrust ball bearing and an excavator including the thrust ball bearing. Background technique [0002] When the bucket of an existing excavator is connected to the horse head through the bucket pin, there will inevitably be a gap between the horse head and the bucket lug. The common practice in the industry is to install a flat washer between the horse head and the bucket ear to eliminate the gap. When the excavator is working, the horse head does not rotate, and the bucket ear and the bucket pin rotate together. Severe dry friction will inevitably occur between the horse head and the flat washer, and between the bucket ear and the flat washer, resulting in serious wear of the horse head and the bucket ear. Severe dry friction is bound to consume a lot of engine power. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art, a...
