Dustproof cooling bearing seat

Abstract

The invention discloses a dustproof cooling bearing seat. The dustproof cooling bearing seat is characterized in that upper half shaft holes and an upper bearing cavity with outer diameter the same as that of a to-be-mounted bearing outer ring are formed in an upper seat body, lower half shaft holes and a lower bearing cavity with outer diameter the same as that of the to-be-mounted bearing outer ring are formed in a lower seat body, the upper bearing cavity and the lower bearing cavity are matched to form a bearing cavity with the outer diameter the same as that of the to-be-mounted bearing outer ring, and bolt holes for connection are formed on flanges of the upper seat body and the lower seat body; upper half sealing grooves are formed in the upper half shaft holes in two sides of the upper bearing cavity of the upper seat body respectively, lower half sealing grooves are formed in the lower half shaft holes in two sides of the lower bearing cavity of the lower seat body, and the upper half sealing grooves and the lower half sealing grooves are matched to form a complete sealing groove. The dustproof cooling bearing seat has the advantages as follows: dust can be prevented from entering the bearing through addition of sealing strips; an oil filling hole is added, so that lubricating oil in the bearing seat cannot be in shortage; a flowing groove is formed in the lower bearing seat, and heat produced by the bearing rotating at a high speed is discharged accordingly.

Description

technical field [0001] The invention belongs to the technical field of bearing seats, and in particular relates to a dust-proof and cooling bearing seat. Background technique [0002] In industrial production, equipment often works in an environment with a lot of dust, and when the bearing works in such an environment, it is bound to have an impact on it. Therefore, whether the bearing seat design of this type of equipment can reduce or even isolate dust from entering the bearing will directly affect the wear degree and service life of the bearing. Design puts forward higher requirements. At present, most of the bearing housings on the market are not designed and manufactured to prevent dust, and they do not take into account that a large amount of heat will be generated when the equipment is running at high speed.

AI Technical Summary

Problems solved by technology

[0003] The bearing seat introduced in the invention patent "a bearing seat" (authorized announcement number: CN 103089826 B) realizes dust isolation through gas, but the disadvantages of this solution are: first, the processing of the annular outlet is relatively difficult. Difficult, and the air passage is a straight passage, which will only blow out from one point when ventilating, and will not form a circular air curtain; second, the annular outlet is in the middle of the shaft hole, which can prevent external dust from entering the bearing. But it will blow the dust left inside the annular outlet on both sides into the bearing
