High-temperature-resistance bearing base

Abstract

The invention discloses a high-temperature-resistance bearing base. The high-temperature-resistance bearing base comprises a bearing base body, a through cover and a sealing cover, wherein the through cover and the sealing cover are respectively arranged on the two ends of the bearing base body, and the bearing base body, the through cover and the sealing cover can form a bearing base cavity body which can contain a bearing. The high-temperature-resistance bearing base is characterized by comprising a shaft sleeve fixedly sleeved on a main shaft, wherein the shaft sleeve is matched with the bearing in the bearing base cavity body and can support the main shaft to rotate; and the bearing base body, the through cover and the sealing cover are sleeved on the shaft sleeve, and the shaft sleeve is provided with a shaft sleeve groove for the passing of a cooling medium, and a liquid inlet and a liquid outlet, wherein the liquid inlet and the liquid outlet are used for the feeding and discharging of the cooling medium. Multiple cooling is adopted, and an inner ring of the bearing, an outer ring of the bearing base body and an inner cavity of the bearing base can carry out full cooling protection on the bearing.

Description

technical field [0001] The invention relates to a high temperature resistant bearing seat. Background technique [0002] Bearing housings are used in many equipment, such as crushers and so on. When the crusher works in a high-temperature working environment or crushes high-temperature materials, the heat will be transferred to the bearing seat through the connecting surface of the main shaft and the bearing seat, causing the temperature of the bearing to rise. The temperature will directly affect the service life of the bearing. If the temperature is too high, the bearing will even be scrapped, and the replacement of the bearing will be troublesome; it will make the equipment unable to operate normally. Therefore, when working in a high temperature working environment or when crushing high temperature materials, it is necessary for It is also necessary to take cooling measures for the bearings, especially in the structural design of the bearing seat of the super-large crus...

AI Technical Summary

Problems solved by technology

The temperature will directly affect the service life of the bearing. If the temperature is too high, the bearing will even be scrapped, and the replacement of the bearing will be troublesome; it will make the equipment unable to operate normally. Therefore, when working in a high temperature working environment or when crushing high temperature materials, it is necessary for It is also necessary to take cooling measures for the bearings, especially in the structural design of the bearing seat of the extra-large crusher.

[0003] There are deficiencies in the existing measures to solve the temperature problem of the bearing seat: the cooling effect of the thin oil circulation cooling in the inner cavity of the bearing is not sufficient; the cost of using high-temperature bearings is high, and it is difficult to purchase extra-large bearings; the independent form of bearing seat (bearing seat and crushing cavity) will greatly increase the length of the working pair, and the heat insulation effect is not obvious
