Simple method for reducing temperature of bearing block and air-cooled bearing structure

Abstract

The invention discloses a simple method for reducing the temperature of a bearing block and an air-cooled bearing structure. According to the simple method for reducing the temperature of the bearing block and the air-cooled bearing structure, the air-cooled bearing structure comprises a bearing block, a bearing frame and an oil seal drum which is connected with the bottom of the bearing frame and arranged around a pump shaft; the center of the bearing block is provided with the pump shaft and a journal around the pump shaft; a bearing cap is arranged on the bearing frame, a bearing is arranged among the journal, the bearing frame and the bearing block, the upper end of the journal extends from the bearing cap, and a fan frame is arranged above the bearing cap, mounted on the pump shaft in a sleeve mode and fixed to the top of the journal; a fan blade for generating axial air flow is arranged around the pump shaft on the fan frame; the bearing frame is a hollow cylindrical housing and provided with a bottom surface, and one or more cooling fins are arranged on the side wall and the bottom surface of the bearing block. The simple method for reducing the temperature of the bearing block and the air-cooled bearing structure have the advantages that the bearing structure is not prone to oil leakage, simple and compact in structure, and small in size, good in cooling effects due to the fact that the air flow can be directly generated above the bearing and the cooling fins are arranged for auxiliary, good in practicability and easy to popularize.

Description

technical field [0001] The invention relates to a bearing refrigeration structure, in particular to a simple method for reducing the temperature of a bearing seat and an air-cooled bearing structure. Background technique [0002] At present, the bearing temperature of vertical long-shaft pumps operating under normal oil lubrication is required to be kept within a range that is not too high; the heat dissipation of heat generated by the friction of this bearing structure can only be achieved through its own heat dissipation and lubricating oil. Circular heat transfer to complete. [0003] In the case that the temperature of the inner ring of the bearing is very high due to the high temperature of the medium itself, the existing bearing structure is to add a water-cooled jacket structure on the periphery of the bearing seat, and use cold flowing water, that is, water cooling. Cool the bearing seat to complete the transfer of bearing heat to the outside and ensure that the bea...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a simple method for lowering the temperature of the bearing seat and an air-cooled bearing structure. The cooling of the bearing is realized by setting a fan on the bearing member, which overcomes the need for continuous external cooling water and inconvenient operation and maintenance in the existing water-cooling method. Shortcoming, thereby realizes the purpose of the present invention
