Description
Technical field
The present invention relates to and belong to mining machinery manufacture field, especially belong to high-pressure roller mill and manufacture field, particularly to 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 work surface of current roller mainly has 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 much more 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. Therefore there is the high-pressure roller mill of potassium steel roll surface have at Medium and smaller mines and sandstone field and bigger make consumption. Potassium steel roll surface in the market is by machining keyway at potassium steel roll surface endoporus, it is directly assembled on main shaft by key type of attachment, this assembling structure can prevent roll surface from use producing to loosen, rotation phenomenon, but owing to potassium steel hardness is high, toughness is big, machining difficulty is very big, 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, significantly cause the waste of metals resources and fund.
Summary of the invention
The purpose of the present invention is that a kind of roller of high-pressure roller mill with potassium steel roll surface of offer, and this roller of high-pressure roller mill stable performance with potassium steel roll surface, easy for installation, using rate of metal is high, and use cost is low.
The technical scheme is that a kind of roller of high-pressure roller mill with potassium steel roll surface, including 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 main shaft orientation step, being provided with the main shaft step corresponding with roller positioning step on the described outerface of spindle, described carbon structure steel bowl is axially positioned by described roller positioning step and described main shaft step.
Compared with prior art, the beneficial effects of the present invention is:
In the present invention, carbon structure steel bowl connects elastic conjunction to main shaft by key, to prevent roller from producing the rotation of circumferencial direction, roller is machined with roller positioning step, by positioning with respective step assembling on main shaft, to prevent it from producing axial motion.
In the present invention, potassium steel roll surface is axially positioned on roller by its roll surface step, bracing ring is assembled to by hexagon socket cap head screw between potassium steel roll surface and roller, bracing ring and roller are Cylindrical Surfaces Contact, it is taper-face contact with potassium steel roller, by tightening hexagon socket cap head screw locking cone match, it is prevented that potassium steel roll surface produces rotation. Bracing ring is semicircle, and on it, processing has fixed thread hole, when part is changed in maintenance, it is not necessary to dismounting bearing, bearing block and end cap etc. can realize the quick alternate maintenance of potassium steel roll surface.
Helpfulness of the present invention, potassium steel roll surface of the present invention assembling structure is convenient to install and maintain, 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 invention will be further described.
As shown in figs. 1-7, a kind of roller of high-pressure roller mill with potassium steel roll surface, including main shaft 1, carbon structure steel bowl 2 and potassium steel roll surface 4.
On main shaft 1 outer cylinder surface 1b, processing has 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 more than roller termination section. Roller termination section external cylindrical surface 2d and roller interlude external cylindrical surface 2e composition. On roll body inner surface, processing has roller positioning step 2a, and on roller interlude external cylindrical surface 2e, processing has 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 on potassium steel roll surface taper surface 4b, processing has roll surface step 4c.
Carbon structure steel bowl 2 is by heating mode flat key 5 and main shaft 1 assembly connection of roller endoporus 2b, it is prevented that carbon structure steel bowl 2 produces the rotation of circumferencial direction.
Carbon structure steel bowl 2 is axially positioned by roller positioning step 2a and main shaft step 1a, it is prevented that 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, assembles 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, the potassium steel roll surface taper surface 4b cone match part of bracing ring taper surface 3b Yu potassium steel roll surface 4 by tightening hexagon socket cap head screw 6 locking support circle 3.
Because bracing ring 3 is semicircular structure, when potassium steel roll surface 4 is changed in maintenance, do not need other parts such as dismounting bearing, i.e. replaceable wearing parts potassium steel roll surface 4.
In figure, " K " is the available thickness of the monolateral metal of potassium steel roll surface, it can be seen that the using rate of metal of the potassium steel roll surface consumable accessory of this kind of structure is very high.
Potassium steel roll surface assembling structure is convenient to install and maintain, 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.
