A kind of Roller of High structure
Technical field
This hair utility model is related to high-pressure roller mill field, specifically a kind of Roller of High structure.
Background technique
Extensive use with high-pressure roller mill in each field, the abrasion and replacement roll body bring of Roller of High
Maintenance cost Upgrade Problem is gradually paid attention to by everybody.Existing Roller of High material is mainly rich chromium cast iron, itself
Material characteristic determines that there is production and processing higher cost, roll surface biggish magnitude of interference cannot be used to be pacified during installation
The defects of filling, being easy to produce crackle after stress at the seamed edge of keyway or even be broken.
The utility model patent novel high-pressure roller mill surface structure just can solve this problem, on roll body surface
The roller set of installation is process by wear-resistant material, and can choose wear-resisting steel plate is preferred material, and material structure is stablized, price
Cheaply, easy to process, material tensile property is excellent, and the mounting means of larger magnitude of interference can be used when installing with roll body.Using
This structure can substantially reduce the processing of Roller of High, maintenance cost.
Summary of the invention
The purpose of this utility model is that ensuring service life and height by this novel high-pressure roller mill surface structure
In chrome cast iron roll body service life approximate situation, the processing and maintenance cost of Roller of High are greatly reduced, shortens processing
Period, assembling structure are also more stable.
In order to achieve the above objectives, the technical solution adopted in the utility model are as follows: a kind of Roller of High structure, including
There is high-pressure roller mill main shaft, be characterized in that: being provided with high-pressure roller mill roller on the outside of position among high-pressure roller mill main shaft
Body, the both ends of high-pressure roller mill roll body are equipped with roller end baffle, and roller end baffle is fixed by screws on high-pressure roller mill roll body,
Roller set is installed, roller end baffle is used to play position-limiting action, the material of roller set when mounted roller covers on the outside of high-pressure roller mill roll body
Wear-resisting steel plate is selected, the quantity of roller set is several.
The advantages of the utility model and beneficial effect are: comparable with existing cast iron class high-pressure roller mill roll body service life
Under the premise of, this Roller of High structure can reduce the high-pressure roller mill roll body processing duration, reduce processing cost, reduce and use
Family use cost.

Specific embodiment
As shown in Fig. 1, Fig. 2, it to include high pressure roller mill owner that the utility model relates to a kind of Roller of High structures
Axis 1, in which: it is provided with high-pressure roller mill roll body among high-pressure roller mill main shaft on the outside of position, the two of 3 high-pressure roller mill roll bodies
End is equipped with roller end baffle 2, and roller end baffle is fixed on high-pressure roller mill roll body by screw 5, outside high-pressure roller mill roll body
Side is equipped with roller set 4, and roller end baffle is used to play position-limiting action, the material selection wear-resisting steel plate of roller set, roller set when mounted roller covers
Quantity be several.
Embodiment one: the outside at the intermediate position of high-pressure roller mill main shaft 1 is high-pressure roller mill roll body 3, and roller end baffle 2 is installed
At the both ends of high-pressure roller mill roll body 3, position-limiting action is played in mounted roller set 4, roller end baffle 2 is fixed to high pressure by screw 5
On roller mill roll body 3.The outsides that roller set 4 is mounted on high-pressure roller mill roll body 3, the thicker wear-resisting steel plate of the material selection of roller set 4,
Wear-resisting steel plate itself has many advantages, such as that material properties is stable, cheap, easy to process, and material itself is again with higher anti-
Tensile strength is relatively suitble to the assembly mode using big magnitude of interference.By roller cover 4 overall dimensions after processing is completed, again by its inner ring ruler
It is very little to be machined to pass through hot charging or the side of cold charge with the size section for according to 3 outer diameter of high-pressure roller mill roll body being interference fit
Roller set 4 is mounted on the corresponding position of high-pressure roller mill roll body 3 by formula.It, can basis due to the limitation of wear-resisting steel plate thickness itself
The wide size of practical roller of roll body is processed several roller sets and is co-mounted on high-pressure roller mill roll body 3.
The roller set of this novel high-pressure roller mill surface structure is process by wear-resistant material, according to high pressure roller roll surface institute
Need width that one or more roller sets is selected to be installed on the body of roll.
The material of roller set can be to be process by materials such as wear-resisting steel plate, wear-resisting steel.
According to the of different size of Roller of High, the quantity of roller set can be one, two or more.
Fixed form between roller set and the body of roll can be the hot charging of interference fit or cold charge mode is fixed, and is also possible to key
It is fixed with the mode that axial baffle is used cooperatively.
Roller set on roll surface can select wear-resisting steel plate to be process, according to the width of high-pressure roller mill roll body, processing one
A or multiple roller sets, using the characteristic of wear-resisting steel plate high-tensile, the matching model using big magnitude of interference is connected with roll body,
Keep overall structure more stable.
