Abstract
The utility model discloses a bearing sealing structure of a cob crusher. The bearing sealing structure of the cob crusher comprises a bearing, wherein the combined position of the machine body at the left side and the right side of the bearing and a main shaft and the combined position of a fan shell body and the main shaft are respectively provided with a sealing disc. According to the structure of each sealing disc, one end of a sleeve pipe matched with the main shaft in the combined position of the machine body and the main shaft is fixedly connected with a nut on the main shaft, the other end of the sleeve pipe is provided with an annular disc opposite to the left end surface of the bearing, the structure of the sealing disc in the combined position of the fan shell body and the main shaft is the same as the structure of the sealing disc in the combined position of the machine body and the main shaft and is also provided with a sleeve pipe and an annular disc, the sealing disc is pressed between a step surface of the main shaft and the fan shell body in a matched mode, and the annular disc of the sealing disc is opposite to the right end surface of the bearing. The bearing sealing structure of the cob crusher has the obvious advantages that powder materials will not enter a bearing chamber and the service life of the bearing is prolonged.
Description
Technical field:
The utility model 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 when 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 utility model technical issues that need to address are from the gap of main shaft and body junction and the gap of main shaft and blower fan junction powder out, not enter bearing chamber, 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 utility model can not enter the bearing chamber raising bearing remarkable advantage in working life.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
In conjunction with following embodiment, the utility model 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 utility model stops powder to enter bearing chamber is, shredder is when work, when powder is from shredder and main shaft junction and blower fan and main shaft junction out time, blocking of two seal discs, dust can not enter bearing chamber, therefore, and the long service life of bearing.Seal disc of the present utility model is simple in structure than adopting low many of the cost of stuffing box bearing, has advantages of that cost is low.
