Description
Technical field
The utility model relates to and belongs to mining machinery manufacture field, especially belongs to high-pressure roller mill and manufactures field, particularly a kind of roller of high-pressure roller mill with potassium steel roll surface.
Background technology
High-pressure roller mill is building stones and mineral manufacture field common equipment, and the working face of current roller mainly contains two kinds of forms: the steel alloy roll surface of tungsten carbide button's stud and potassium steel roll surface.Wherein the service life of the steel alloy roll surface of tungsten carbide button's stud is longer, but its to change part cost very expensive; The service life of potassium steel roll surface is short compared with the steel alloy roll surface of tungsten carbide button's stud, but its alternate maintenance cost is low.The high-pressure roller mill therefore with potassium steel roll surface has larger use amount at Medium and smaller mines and sandstone field.Potassium steel roll surface in the market passes through at potassium steel roll surface endoporus machined keyway, directly be assembled on main shaft by key type of attachment, it is loosening that this assembly structure can prevent roll surface from use producing, rotation phenomenon, but because potassium steel hardness is high, toughness is large, machined difficulty is very large, and the roll surface of this form can cause the using rate of metal of potassium steel low, when alternate maintenance, still there is greater weight potassium steel roll surface can directly be replaced by new accessory, greatly cause the waste of metals resources and fund.
Utility model content
The purpose of this utility model is just to provide a kind of roller of high-pressure roller mill with potassium steel roll surface, and the high-pressure roller mill roller stable performance of this band potassium steel roll surface, easy for installation, using rate of metal is high, and use cost is low.
The technical solution of the utility model is: a kind of roller of high-pressure roller mill with potassium steel roll surface, comprise main shaft, carbon structure steel bowl and potassium steel roll surface, described carbon structure steel bowl is connected with described main shaft by a flat key, described carbon structure steel bowl inner surface is provided with roller positioning step, the described outerface of spindle is provided with the main shaft step corresponding with roller positioning step, described carbon structure steel bowl is by described roller positioning step and described main shaft step axial location.
Compared with prior art, the beneficial effects of the utility model are:
In the utility model, carbon structure steel bowl connects elastic conjunction on main shaft by key, and with the rotation preventing roller from producing circumferencial direction, on roller, machined has roller positioning step, by with respective step assembling and positioning on main shaft, with prevent its produce axial motion.
In the utility model, potassium steel roll surface is axially positioned on roller by its roll surface step, bracing ring is assembled between potassium steel roll surface and roller by hexagon socket cap head screw, support that circle and roller are Cylindrical Surfaces Contact, be taper-face contact with potassium steel roller, by tightening hexagon socket cap head screw locking cone match, prevent potassium steel roll surface from producing rotation.Bracing ring is semicircle, it is processed with fixed thread hole, when part is changed in maintenance, does not need dismounting bearing, bearing block and end cap etc. can realize the quick alternate maintenance of potassium steel roll surface.
The utility model helpfulness, the installation and maintenance of the utility model potassium steel roll surface assembly structure are convenient, and using rate of metal is high, reduces the use cost of the main consumable accessory of high-pressure roller mill, improves the productivity effect of high-pressure roller mill.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figs. 1-7, a kind of roller of high-pressure roller mill with potassium steel roll surface, comprises main shaft 1, carbon structure steel bowl 2 and potassium steel roll surface 4.
Main shaft 1 outer cylinder surface 1b is processed with main shaft step 1a.
Carbon structure steel bowl 2 is made up of roller endoporus 2b and roll body, and roll body is made up of roller termination section and roller interlude, and roller interlude diameter is greater than roller termination section.Roller termination section external cylindrical surface 2d and roller interlude external cylindrical surface 2e forms.Roll body inner surface is processed with roller positioning step 2a, roller interlude external cylindrical surface 2e is processed with roll surface positioning step 2c.
Potassium steel roll surface 4 is made up of potassium steel roll surface endoporus 4a and potassium steel roll surface wall, and potassium steel roll surface wall inwall is potassium steel roll surface taper surface 4b, and potassium steel roll surface taper surface 4b is processed with roll surface step 4c.
Carbon structure steel bowl 2, by mode flat key 5 and main shaft 1 assembly connection of heating roller endoporus 2b, prevents carbon structure steel bowl 2 from producing the rotation of circumferencial direction.
Carbon structure steel bowl 2, by roller positioning step 2a and main shaft step 1a axial location, prevents carbon structure steel bowl 2 axial motion.
Potassium steel roll surface 4 is axially positioned on the roll surface positioning step 2c of carbon structure steel bowl 2 by roll surface step 4c, and the potassium steel roll surface endoporus 4a of potassium steel the roll surface 4 and external cylindrical surface 2e of carbon structure steel bowl roller 2 is elastic conjunction, assembling mode hot charging.
Bracing ring 3 is semicircular structure, and inner ring surface is bracing ring face of cylinder 3a, and outer ring surface is bracing ring taper surface 3b, on bracing ring 3 circumferentially on have a circle countersunk head through hole.
In the space that the potassium steel roll surface taper surface 4b of roller termination section external cylindrical surface 2d and potassium steel roll surface 4 that bracing ring 3 is assemblied in carbon structure steel bowl 2 is formed, the bracing ring face of cylinder 3a of bracing ring 3 contacts with the roller termination section external cylindrical surface 2d of carbon structure steel bowl 2, and the bracing ring taper surface 3b of bracing ring 3 contacts with the potassium steel roll surface taper surface 4b of potassium steel roll surface 4.
Hexagon socket cap head screw 6 and self-locking packing ring 7 are assemblied in the counter sink on bracing ring 3, by the potassium steel roll surface taper surface 4b cone match part of the bracing ring taper surface 3b and potassium steel roll surface 4 that tighten hexagon socket cap head screw 6 locking support circle 3.
Because bracing ring 3 is semicircular structure, during maintain and replace potassium steel roll surface 4, do not need other parts such as dismounting bearing, i.e. replaceable wearing parts potassium steel roll surface 4.
In figure, " K " can utilize thickness for the monolateral metal of potassium steel roll surface, and the using rate of metal of the potassium steel roll surface consumable accessory of this kind of structure is very high as can be seen here.
The installation and maintenance of potassium steel roll surface assembly structure are convenient, and using rate of metal is high, reduces the use cost of the main consumable accessory of high-pressure roller mill, improves the productivity effect of high-pressure roller mill.
