Bearing capable of preventing oil from being sucked back

Abstract

The invention discloses a bearing capable of preventing oil from being sucked back. The bearing capable of preventing the oil from being sucked back comprises an outer ring of the bearing and an innerring of the bearing, wherein a plurality of rolling balls are mounted between the outer ring of the bearing and the inner ring of the bearing, and the rolling balls sleeve a holder; adjacent rollingballs are connected through the holder; rolling ball grooves for mounting the rolling balls are formed in the inner ring of the bearing; a lubricating oil channel with a trapezoidal section is formedin the inner ring of the bearing; the end with large diameter of the lubricating oil channel is provided with an oil inlet, and the end with small diameter of the lubricating oil channel is provided with an oil outlet; a filtering plate is arranged in the lubricating oil channel; a spring is mounted on the inner wall of the filtering plate, and one end of the spring is connected to a steel ball. According to the bearing capable of preventing the oil from being sucked back, the lubricating oil channel is arranged, and the filtering plate is mounted in the lubricating oil channel and is capableof filtering lubricating oil, so that the abrasion of the impurity in the lubricating oil to the rolling balls can be prevented; the spring is arranged and is connected to the steel ball, the small-diameter end of the lubricating oil channel can be sealed through the steel ball, and thus the lubricating oil is prevented from flowing out from the lubricating oil channel to be sucked back.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an oil-sucking-proof bearing. Background technique [0002] Bearings are used to determine the relative movement position of the rotating shaft and other parts, and play a supporting or guiding role. The main function of the bearing is to support the rotating shaft or other moving body, guide the rotation or movement and bear the load transmitted by the shaft or parts on the shaft. Bearings are an indispensable basic component in contemporary machinery and equipment, and are widely used in various industries of the national economy. Its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine. . [0003] According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings are generally comp...

Problems solved by technology

Bearings with this structure are provided with lubricating passages, although the lubrication effect can be improved, but when the oil enters the cavity of the bearing through the lubricating passages, the oil is prone to suck back, resulting in a decrease in the lubricating effect and heat dissipation performance.
