Abstract
The utility model discloses the diamond major axis drive mechanism of a kind of high speed mill, comprise emery wheel support and be arranged on the transmission main shaft on emery wheel support, described transmission main shaft is regular prism, the cross section of described regular prism is regular polygon, the limit number of described regular polygon is more than or equal to 4, and the endoporus for placing transmission main shaft on described emery wheel support is also set to the regular polygon hole adapted with transmission main shaft.The diamond major axis drive mechanism of high speed mill (ring roller mill) of the present utility model is by spindle processing diamondwise, and trepanning in the middle of emery wheel support is also processed into corresponding rhombus, this shape and structure is compared with traditional keyway arrangements, and it is comparatively easy to manufacture, thus saves processing cost.When assembling, only emery wheel support directly need be inserted in and can complete; During dismounting, need not specific purpose tool, layer can be pressed like a cork from top to bottom and take out emery wheel support, need not integral demounting.
Description
Technical field
The utility model belongs to high speed mill field, is specifically related to the diamond major axis drive mechanism of a kind of high speed mill.
Background technology
Rotatable parts at a high speed in mill (ring roller mill) and the critical piece of crushing auxiliary are emery wheel support, and in the middle of emery wheel support, inserting main shaft as transmission mechanism.When driven by motor main axis, main shaft drives emery wheel support to rotate together, thus realizes the effect of pulverizing.The effect of main shaft is that support rotary parts and emery wheel support also turn round to transmit motion, moment of torsion or moment of flexure therewith.In the utilization of pulverizer, it is shaft-like that main shaft is generally round metal, and each section can have different diameters.And grind at a high speed (ring roller mill) as the high speed running apparatus in pulverizer in recent years; its main shaft still inherits the mentality of designing of pulverizer usually; for cylindrical object or the cylindrical object for band tapering; and adopt key-way shape structure, utilize the interlocking of protruding key and recessed groove to carry out joint transmission.And in actual use, when needs keep in repair crushing auxiliary, or when needing to change consumable accessory, the existing high speed mill main shaft run up of (ring roller mill) and the parts of gyration due to weight comparatively greatly, and must cross tight fit, this key slot type structure causes that to dismantle difficulty large, add the workload of plant maintenance and maintenance, the labour intensity of workman is large, and the time of equipment maintenance is long, thus affects the economic benefit of enterprise.
Utility model content
Large in order to overcome existing main shaft driving structure dismounting difficulty, the deficiency that maintenance time is long, the utility model provides a kind of novel diamond major axis drive mechanism, this structure not only reduces manufacture difficulty, and when needs keep in repair crushing auxiliary or need to change crushing auxiliary consumable accessory, be more prone to dismounting, the difficulty greatly reducing maintenance or safeguard, saves the time greatly.
The purpose of this utility model is achieved through the following technical solutions:
A kind of diamond major axis drive mechanism of high speed mill, comprise emery wheel support and be arranged on the transmission main shaft on emery wheel support, described transmission main shaft is regular prism, the cross section of described regular prism is regular polygon, the limit number of described regular polygon is more than or equal to 4, and the endoporus for placing transmission main shaft on described emery wheel support is also set to the regular polygon hole adapted with transmission main shaft.
Further, the regular polygon hole on described emery wheel support and be matched in clearance between transmission main shaft, the cross section of described transmission main shaft is set to positive 4-10 limit shape.
The beneficial effects of the utility model are: the diamond major axis drive mechanism of high speed mill (ring roller mill) of the present utility model is by spindle processing diamondwise, and trepanning in the middle of emery wheel support is also processed into corresponding rhombus, this shape and structure is compared with traditional keyway arrangements, it is comparatively easy to manufacture, thus saves processing cost.When assembling, only emery wheel support directly need be inserted in and can complete; During dismounting, need not specific purpose tool, layer can be pressed like a cork from top to bottom and take out emery wheel support, need not integral demounting.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by description below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is diamond major axis schematic perspective view of the present utility model.
Fig. 2 is emery wheel support top view of the present utility model.
Fig. 3 is the sectional view of Fig. 2.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in the figure, a kind of diamond major axis drive mechanism of high speed mill, the transmission main shaft 1 comprising emery wheel support 2 and be arranged on emery wheel support, described transmission main shaft 1 is regular prism, the cross section of described regular prism is regular polygon, the limit number of described regular polygon is more than or equal to 4, and the endoporus for placing transmission main shaft on described emery wheel support is also set to the regular polygon hole adapted with transmission main shaft.
The diamond major axis drive mechanism of high speed mill (ring roller mill) of the present embodiment is by spindle processing diamondwise, and trepanning in the middle of emery wheel support is also processed into corresponding rhombus, this shape and structure is compared with traditional keyway arrangements, and it is comparatively easy to manufacture, thus saves processing cost.When assembling, only emery wheel support directly need be inserted in and can complete; During dismounting, need not specific purpose tool, layer can be pressed like a cork from top to bottom and take out emery wheel support, need not integral demounting.
As further improvement of this embodiment, the regular polygon hole on described emery wheel support and be matched in clearance between transmission main shaft, the cross section of described transmission main shaft is set to positive 4-10 limit shape.When overall processing main shaft, main shaft portion structure is processed as regular prism, and regular prism cross section can be regular polygon, and regular polygon limit number can be 4-10 bar limit.Emery wheel support endoporus is processed into corresponding regular polygon.Main shaft and emery wheel support need not cross tight fit, convenient applicable on assembly and disassembly wheel disc emery wheel support.Do not affect the working strength of main shaft when transmission on moment of torsion simultaneously.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
