Abstract
The utility model discloses a grinding roller structure of a vertical mill, which comprises a roller sleeve on a spindle. A roller sheet is fastened on the roller sleeve through hold-down iron wedges, the roller sleeve, the roller sheet and the iron wedges are fastened integrally through long bolts, two bearings are arranged in a bearing chamber, a spacer bush is arranged between the two bearings, seal caps are arranged at two ends of the bearing chamber, and the grinding roller can be pressurized by the aid of the seal caps acting onto the bearing chamber.
Description
Technical field
The utility model relates to a kind of grinding roller structure of Vertical Mill, especially adapts on the Burnisher apparatus of medium-sized Vertical Mill.
Background technology
Well-known Vertical Mill has abrasive dust efficient height, simple in structure, reliable operation, keep in repair easyly, many characteristics such as operating cost is low are widely used in cement, electric power, metallurgical, industrial departments such as nonmetallic ore, but exist the grinding roller bearing replacing frequent, drawbacks such as bearing life is short have a strong impact on production, in conjunction with explanation shown in Figure 1, the roller skin 1 of grinding roller is installed in the outer rim of bearing chamber 2, roller is worked in grinding chamber, and the temperature in the grinding chamber is quite high, and one is higher from the hot blast self-temperature of hot-blast stove, the temperature that produces during its two improved grinding, in the environment of high temperature, even thin oil lubricant is arranged, the life cycle of bearing 3 is still very short fully for whole bearing 3.
Summary of the invention
The purpose of this utility model provides a kind of grinding roller structure of Vertical Mill at above-mentioned the deficiencies in the prior art.
For achieving the above object, the utility model can be taked following technical proposals:
The grinding roller structure of a kind of Vertical Mill described in the utility model, it comprises the roller shell that is positioned on the main shaft, the roller skin is fastened on the roller shell by dog wedge iron, stay bolt fastens as one roller shell, roller skin, drift, two bearings in the bearing chamber, in the middle of it spacer is arranged, there is seal cover at two ends, by can realize the pressurization to grinding roller to the bearing chamber effect.
Described grinding roller bearing chamber is in the outside of work mill chamber.
Positive progressive effect of the present utility model is, the grinding roller structure of the utility model Vertical Mill simple and reasonable away from high operating temperature in the mill chamber, reduced bearing use temp beyond doubt, improves its service life, improves the operating rate of equipment.
Description of drawings
Fig. 1 is the front view of the existing vertical mill roll structure of this practicality.
Fig. 2 is the front view of the utility model vertical mill roll structure.
The specific embodiment
As shown in Figure 2, the grinding roller structure of a kind of Vertical Mill described in the utility model, it comprises the roller shell 1 on the main shaft 5, roller skin 3 is fastened on the roller shell 1 by compressing drift 2, stay bolt 4 fastens as one roller shell 1, roller skin 3, drift 2, and two bearings 9 in the bearing chamber 7 have a spacer 8 in the middle of it, there is seal cover 6 at two ends, by bearing chamber 7 is acted on the pressurization that can realize grinding roller.
Described grinding roller bearing chamber 7 is in the outside of work mill chamber.
Though more than described the specific embodiment of this programme, it should be appreciated by those skilled in the art that this only illustrates, all should be in protection domain in principle of the present utility model and essence, concrete embodiment can change to some extent.
Claims (2)
