Abstract
The utility model relates to a novel grinding roller structure of a vertical grinder. The novel grinding roller structure of the vertical grinder comprises a roller sleeve, a roller core and a pressing structure, wherein the roller core is sleeved with the roller sleeve; the roller sleeve is pressed and fixed on the roller core by virtue of the pressing structure; the pressing structure comprises a pressing ring; a contact surface between the roller sleeve and the pressing structure is a cylindrical surface. By virtue of the design of the cylindrical surface of the roller sleeve, the processing difficulty and the processing cost are reduced. The pressing structure also comprises an expanding sleeve; the expanding sleeve has a conical surface which is matched with the pressing ring; the expanding sleeve is arranged between the pressing ring and the roller sleeve. The conical surface is not required to be processed on the roller sleeve, but the conical surface is processed on the expanding sleeve and the pressing ring and subsequently pressed into the expanding sleeve and the pressing ring, so that the processing difficulty and the processing cost are reduced. Once the roller sleeve is out of service, only is the roller sleeve processed independently; the expanding sleeve and the pressing ring can be reused, so that the reusability can be achieved after processing for one time. The roller sleeve is of a symmetric structure; when one end of the roller sleeve is excessively abraded, the roller sleeve can be inverted, so that the purpose of secondary use is achieved.
Description
Technical field
The utility model relates to a kind of vertical roller grinder technical field, relates in particular to a kind of Novel vertical mill grinding roller structure.
Background technology
Present Domestic grinding roller of vertical mill structure takes to process the conical surface on roller shell, the mode then compressing with the same pressure ring of processing the conical surface.Under prior art, processing roller shell conical surface difficulty is larger, and the very difficult assurance of precision, once roller shell is scrapped, needs again to process, and manufacturing cost and working service cost are all higher.
Utility model content
For above problem the utility model, a kind of easy processing, maintenance cost is low, utilization rate is high Novel vertical mill grinding roller structure are provided.
In order to overcome the above problems the utility model, provide a kind of Novel vertical mill grinding roller structure, comprise roller shell, roller core, compressing structure, roller shell is enclosed within on roller core, and by compressing structure, roller shell is pressed abd fixed on roller core, described compressing structure comprises pressure ring, it is characterized in that: described roller shell and the contact-making surface of compressing structure are the face of cylinder.The design on the roller shell face of cylinder has reduced difficulty of processing and processing cost.
Described compressing structure also comprises expansion set, and expansion set has the conical surface matching with pressure ring, and expansion set is arranged between pressure ring and roller shell.This grinding roller roller shell does not need to process the conical surface, but process the conical surface on expansion set and pressure ring, then be pressed into expansion set and pressure ring, reduce difficulty of processing and processing cost, once roller shell is scrapped, only needed processing roller shell separately, expansion set and pressure ring are reusable, accomplished that time processing repeatedly utilizes, realized reduction manufacturing cost and working service cost, significantly improved its economy.
Described roller shell is symmetrical structure.When roller shell one end, wear and tear when excessive, roller shell can also be overturn, reach the object that secondary is used.
Described pressure ring is fixed by studs and self-locking nut.Dismantle, install more convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1: 1-roller shell; 2-roller core; 3-expansion set; 4-pressure ring; 5-studs; 6-face of cylinder; 7-conical surface.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model provides a kind of Novel vertical mill grinding roller structure, comprises roller shell 1, roller core 2, expansion set 3,
Pressure ring 4; Roller shell 1 is symmetrical structure.Roller shell 1 is enclosed within on roller core 2, and by compressing structure (expansion set 3, pressure ring 4), roller shell 1 is pressed abd fixed on roller core 2; Expansion set 3 is arranged between pressure ring 4 and roller shell 1, and expansion set 3 is the conical surface 7 with the contact-making surface of pressure ring 4, and expansion set 3 is the face of cylinder 6 with the contact-making surface of roller shell 1, and pressure ring 4 is fixed by studs 5 and self-locking nut.
The foregoing is only preferred embodiment of the present utility model, be not restricted to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
