Immersion type cooling press bearing shell

Abstract

The present invention provides a immersion type cooling press bearing shell, the inner surface and two ends with flanges of the existing semicircular column shaped bearing shell will not be changed, the back of the bearing shell is provided with several cooling water tanks along the circumference or axial direction, and the tanks are connected to form a continuous water transfer tank, after assembling the bearing shell with corresponding bearing block, a closed, single and uninterrupted cooling water transfer channel will be obtained by matching a water outlet and a water inlet. A back reinforcing rod of the bearing shell is formed between two neighboring water tanks of the bearing shell. The outer surface of the bearing shell is provided with a water transfer cooling tank, thereby the cooling area of the bearing shell is larger, the external cylindrical surface and the reinforcing rod of the whole bearing shell are all immersed in the cooling water of the water transfer cooling channel, the cooling effect is good without heat distortion; secondly, the reinforcing rod reinforces the strength and the steel degree of the bearing shell, when reloading to operate, there is non mechanical deformation, thereby the service life of the bearing shell is prolonged, and the production cost is reduced.

Description

technical field [0001] The invention relates to a sugar cane press bearing bush of a sugar making machine, in particular to a press bearing bush with cooling water delivery grooves arranged on the back of the bearing bush. Background technique [0002] In the sugar cane sugar industry, the two-roll or three-roll presses usually used are made of bronze bearing bushes, which are placed on the steel bearing shell, and the joint between the two is sealed with a rubber strip, and the lubricating oil channel enters through the bearing shell. Bearing bush, when the press is working, the heat generated by the friction between the journal of the pressing roller and the bearing bush is cooled by the cooling water jacket in the bearing shell to the back of the bearing bush to keep the bearing bush in the normal temperature range. Due to the limitation of the structure of the bearing shell, the water cooling area of ​​this kind of bearing bush is small. When the press machine works cont...

AI Technical Summary

Problems solved by technology

Due to the limitation of the structure of the bearing shell, the water cooling area of ​​this kind of bearing bush is small. When the press machine works continuously and the daily crushing capacity increases, or due to problems in production management, such as poor quality of lubricating oil, contact with the journal Due to poor cooling water supply and other reasons, the bearing pads running under low-speed heavy-duty vehicles, especially the top roller bearing pads of the press, often increase the heat generated by friction, resulting in an increase in the temperature of the bearing pads, resulting in overheating deformation, and then occurrence Water leakage, interruption of lubricating oil circuit, and even smoking and cracking of bearing pads, resulting in production shutdown accidents

For this reason, the emergency measures of pouring cooling water directly to the bearing bush are often adopted at the production site. cost
