Abstract
The invention discloses a corncob crusher bearing sealing device comprising a bearing. The part, connected with a spindle, of a crusher body, and the part, connected with the spindle, of a fan shell are provided with two sealing discs on the left and right sides of the bearing. The sealing discs are characterized in that sleeves match with the parts, connected with the crusher body, of the spindle, one end of each sleeve is fixedly connected with a nut on the spindle, the other end of each sleeve is provided with a circular disc facing the left end face of the bearing, and the sealing disc at the part, connected with the spindle, of the fan shell and the sealing disc at the part, connected with the spindle, of the crusher body are the same in structure; the other sealing disc is also provided with a sleeve and a circular disc, the sealing disc is press-fitted between a step face of the spindle and the fan shell, and the circular disc of the sealing disc faces the right end face of the bearing. The corncob crusher bearing sealing device has the advantages that powder never enters a bearing chamber and the service life of the bearing is prolonged accordingly.
Description
Technical field:
The present invention relates to a kind of sealing technique, particularly a kind of breaking machine for cobs associated sealing arrangement for bearings.
Background technique:
Breaking machine for cobs is a large amount of powder that produces in the time of work, the blast producing due to the High Rotation Speed of rotor mill and fan rotor makes part powder from the gap of main shaft and body junction and produce by boasting in the gap of main shaft and blower fan junction enters bearing chamber, causes bearing Rapid Damage.
Summary of the invention:
The technical issues that need to address of the present invention are not enter bearing chamber from the gap of main shaft and body junction and the gap of main shaft and blower fan junction powder out, thereby improve the working life of bearing.
The technological scheme that solves the defect of above-mentioned prior art existence is, a kind of breaking machine for cobs associated sealing arrangement for bearings, comprise bearing, it is characterized in that: on a described bearing left side, the body of right both sides and main shaft junction and Blower Housing and main shaft junction are respectively provided with a seal disc, the structure of described seal disc is, the sleeve pipe matching with the main shaft of body and main shaft junction, nut on one end and the main shaft of this sleeve pipe is connected, it is relative with the left side of described bearing that the other end of this sleeve pipe is provided with annular disk, Blower Housing is identical with the structure of the structure of the seal disc of main shaft junction and the seal disc of above-mentioned body and main shaft junction, also there is a sleeve pipe and annular disk, this seal disc press fit between the step surface and Fan casing of main shaft, the annular disk of this seal disc is relative with the right side of described bearing.
Thereby having powder compared with the prior art, the present invention can not enter the bearing chamber raising bearing remarkable advantage in working life.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Embodiment:
In conjunction with following embodiment, the present invention is elaborated, the defect that adopts seal disc to be overcome powder and enter bearing chamber, described seal disc is the sleeve pipe matching with main shaft and blocks the annular disk in the gap of bearing and main shaft junction, described sleeve pipe and annular disk are structure as a whole, the casing pipe sleeve of seal disc 4 is located on the main shaft 1 of body 3 and main shaft junction, nut 2 on this sleeve pipe and main shaft is connected by welding, the annular disk of this seal disc 4 is relative with the left side of bearing 5, another seal disc 7 is set in Blower Housing 6 and combines with main shaft on the main shaft of locating, this seal disc is pressed on by Blower Housing 6 on the step surface of main shaft, seal disc 7 and main shaft and Blower Housing are connected, the annular disk of this seal disc 7 is relative with the right side of described bearing, the structure of seal disc 7 is identical with seal disc 4.
The principle that the present invention stops powder to enter bearing chamber is, shredder in the time of work, when powder is from shredder and main shaft junction and blower fan and main shaft junction out time, the blocking of two seal discs, dust can not enter bearing chamber, therefore, the long service life of bearing.Seal disc of the present invention is simple in structure than adopting low many of the cost of stuffing box bearing, has advantages of that cost is low.
