Problems solved by technology
[0003] The corn cob grinder produces a large amount of powder when it is working. Due to the wind pressure generated by the high-speed rotation of the grinder rotor and the fan rotor, part of the powder is blown from the gap between the main shaft and the machine body and the gap between the main shaft and the fan. Come out and enter the bearing chamber, causing rapid damage to the bearing

Embodiment Construction
[0008] The present invention will be described in detail in conjunction with the following examples, and the defect that powder enters the bearing chamber is overcome by adopting a sealing disc. The sealing disc is a bushing matched with the main shaft and an annular disc that blocks the gap between the bearing and the main shaft. The casing and the annular disk are integrated. The casing of the sealing disk 4 is set on the main shaft 1 at the junction of the body 3 and the main shaft. The casing and the nut 2 on the main shaft are fixedly connected by welding. The disc is opposite to the left end face of the bearing 5, and another sealing disc 7 is set on the main shaft where the fan housing 6 and the main shaft are combined, and the sealing disc is pressed against the step surface of the main shaft by the fan housing 6 , the sealing disc 7 is fixedly connected with the main shaft and the fan casing, the annular disc of the sealing disc 7 is opposite to the right end face of t...

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
[0001] Technical field: [0002] The invention relates to a sealing technology, in particular to a bearing sealing device of a corn cob pulverizer. Background technique: [0003] The corn cob grinder produces a large amount of powder when it is working. Due to the wind pressure generated by the high-speed rotation of the grinder rotor and the fan rotor, part of the powder is blown from the gap between the main shaft and the machine body and the gap between the main shaft and the fan. Come out and enter the bearing chamber, causing rapid damage to the bearing. Invention content: [0004] The technical problem to be solved in the present invention is that the powder coming out from the gap between the main shaft and the body and the gap between the main shaft and the fan does not enter the bearing chamber, thereby improving the service life of the bearing. [0005] The technical solution to solve the above-mentioned defects in the prior art is a bearing sealing device for c...
