Self-lubricating bearing pedestal

Abstract

The invention relates to the technical field of bearing pedestals, in particular to a self-lubricating bearing pedestal. The self-lubricating bearing pedestal comprises a bearing pedestal main body and a bearing bush arranged in a center axial hole of the bearing pedestal main body. A lubricating ring filled with lubricating oil is arranged inside the bearing bush. The lubricating ring communicates through the outside world through balls arranged on the inner wall of the bearing bush and used for guiding liquid. The inner wall of the bearing bush is provided with a notch for installation of the balls. The upper edge of the notch is provided with a bearing wall matched with the balls. The notch communicates with the lubricating ring through a corresponding oil conveying channel, the inner wall of the lubricating ring is coated with protection paint, the lubricating ring is provided with an oil injection hole, a sealing plug is arranged in the oil injection hole, traditional opening typeself-lubricating agent filling holes are replaced with the balls for guiding liquid, and lubricating agent is prevented from flowing out. Self lubrication for a rotating shaft is achieved through theballs making rolling contact with the outer surface of the rotating shaft, therefore, friction force between the rotating shaft and the bearing bush is reduced, and the transmission efficiency is improved during self lubricating.

Description

technical field [0001] The invention relates to the technical field of bearing seats, in particular to a self-lubricating bearing seat. Background technique [0002] The bearing seat is a large and extra-large bearing seat that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, and convenient maintenance of the device. Where there is a bearing, there must be a support point. The inner support point of the bearing is The shaft and the outer support are often referred to as bearing housings. The inner bearing bush and the rotating shaft in the existing bearing seat are prone to heat and wear due to rotation, so a lubricating oil outlet is added on the inner wall of the bearing bush. For example, the application number is CN201220287583.7, and the application date is June 19, 2012. Lubricated Sliding Bearing Housing" patent, the bearing housing through the self-lubricating agent filling hole filled w...

Problems solved by technology

[0003] In order to overcome the deficiency that the existing self-lubricating agent cannot be evenly coated on the surface of the rotating shaft, the present invention provides a self-lubricating bearing seat, which solves the problem by filling lubricating oil inside the bearing pad and setting balls on the inner wall of the bearing pad
