Sealed bearing seat suitable for severe working environment

Abstract

The invention relates to the technical field of bearing seats, in particular to a sealed bearing seat suitable for a severe working environment. The sealed bearing seat suitable for the severe workingenvironment comprises a seat body, an end cover, a shaft, a supporting ring, a bearing fixing ring, a sealing ring, a sealed bearing, a floating oil seal and a pressure relief oil nozzle. The sealedbearing seat suitable for the severe working environment has the advantages that two independent oil paths are arranged, the oil paths in the sealed bearing seat are divided into two by the sealing ring, the uncertainty is reduced, old lubricating grease can be directionally discharged, the lubricating quality is improved, and the service life of the bearing seat is prolonged; multiple sealing protection is achieved by combining floating oil seal, a labyrinth structure and the sealed bearing, and the reliability of the bearing seat is improved; a centralized oil supply system is used for supplying oil to the sealed bearing seat, so that the bearing seat is convenient to operate; and parts of the sealed bearing seat can be detached from the end of a shaft, and are convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of bearing seats, in particular to a sealed bearing seat adapted to harsh working environments. Background technique [0002] During mining operations, low-speed and heavy-duty mining equipment such as scraper feeders are often buried under minerals or in harsh working environments such as dust and sand, which is inconvenient to maintain and easily damaged if the bearing housing is not well sealed. Therefore, The sealing requirements and maintenance requirements for bearing seats are further improved, and a sealed bearing seat suitable for harsh working environments is urgently needed. Contents of the invention [0003] In order to solve the problems mentioned in the background technology, the present invention provides a sealed bearing seat adapted to harsh working environments, including a seat body and an end cover, and is characterized in that it also includes a shaft, a support ring, a bearing fixing ...
