Description
One, technical field
The utility model belongs to size reduction machinery.Relate in particular to a kind of vertical-type planetary propellers grinding machine.
Two, background technology
Planet propellers grinding machine [Sun Chunbao, Li Ruihua, Lu Shouci.The operation principle and the characteristics thereof of Szego mill.Mining machinery, 1998, (7)] be a kind of ultra-fine grinding equipment that develops in recent years, can directly produce superfine powder, have efficient height, energy consumption is low, automaticity is high characteristics.But because planet propellers grinding machine is a kind of high speed and high pressure disintegrating apparatus that hard material is pulverized that is used for, its major part damages easily, influences its service life:
The one, grinding ring bears high-frequency and high-voltage alternation fatigue load, is easy to generate fatigue crack, causes grinding ring to break, and its is shortened in service life, and sometimes even can only turn round tens hours, this situation has had a strong impact on the normal operation of grinding machine and applied;
The 2nd, in mill running,, cause the stuck or eccentric wear of propellers easily and cause propellers to damage too early because that thickness of feed layer changes is excessive, have greatly difficult-to-grind materials particle or material to distribute inconsistently along the grinding ring axial width.
For above-mentioned reasons, had a strong impact on grinding machine ordinary production, its life-span is shortened greatly, strengthened production cost.
Three, summary of the invention
The vertical-type planetary propellers grinding machine that the utility model aims to provide a kind of energy ordinary production, improves service life, reduces production costs.Mainly be the grinding ring mechanical characteristic that improves vertical-type planetary propellers grinding machine, the generation that stops or slow down fatigue crack, prolong grinding ring service life, prevent that the stuck or inhomogeneous eccentric wear that causes of stand under load of propellers is to prolong propellers service life.
To achieve these goals, the technical solution adopted in the utility model is: by the motor belt kind of drive or hydraulic transmission mode drive shaft, main shaft vertically is installed in the middle of grinding ring, the grinding ring cover, propellers are installed in the main shaft channeled disks by bearing block, and upper and lower bearing block connects with the grinding ring cover respectively.
Propellers are solid roll, and bearing block is installed in the two ends of propellers, and bearing block moves in the main shaft channeled disks with propellers.
Adopt the conical surface to connect between grinding ring and the grinding ring cover, the lower surface of top chock is pressed on the upper surface of grinding ring, by the compressive pre-stress of bolt adjusting grinding ring.
The left and right sides two side faces of bearing block matches with the guide groove side of main shaft channeled disks, and the lower surface of bearing block radially is pressed on the rubber spring along the main shaft channeled disks.The end face that bearing block matches with the guide groove end face of main shaft channeled disks vertically is an arc surface.
Owing to adopt technique scheme, the characteristics that the utlity model has the energy ordinary production, improve service life, reduce production costs.Be in particular between grinding ring and the grinding ring cover and adopt the conical surface to connect, grinding ring is applied adjustable compressive pre-stress, improved the mechanical characteristic of grinding ring, stop or slow down the generation of fatigue crack, prolonged grinding ring service life by top chock and bolt; In addition,, improved the influence of thickness of feed layer variation and difficult-to-grind materials particle, can prevent the stuck and eccentric wear of propellers, prolonged the service life of propellers propellers because propellers can produce three degrees of freedom of movement in the main shaft channeled disks.
Four, description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the A-A partial sectional view of Fig. 1.
Five, the specific embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is described further:
A kind of specific embodiment of the present utility model as shown in Figure 1, pass through belt pulley drive shaft [8] by motor, main shaft [8] vertically is installed in the middle of grinding ring [3], the grinding ring cover [4], propellers [5] are installed in the main shaft channeled disks [10] by bearing block [7], and grinding ring cover [4] connects with upper and lower bearing block [1], [9] respectively.
Adopt the conical surface to connect between grinding ring [3] and the grinding ring cover [4], the lower surface of top chock [1] is pressed on the upper surface of grinding ring [3], by the compressive pre-stress of bolt [2] adjusting grinding ring [3].
Propellers [5] are solid roll, and bearing block [7] is installed in the two ends of propellers [5], and bearing block [7] moves in main shaft channeled disks [10] with propellers [5].The left and right sides two side faces of bearing block [7] matches with the guide groove side of main shaft [8] channeled disks, and the lower surface of bearing block [7] radially is pressed on the rubber spring [6] along main shaft channeled disks [10].Bearing block [7] is an arc surface with the end face that the guide groove end face of main shaft channeled disks [10] matches vertically.
When main shaft [8] produces the rotation of diagram clockwise direction, propellers [5] also will be done the clockwise direction revolution with main shaft [8], simultaneously in the torque of main shaft [8] and grinding ring [3] under the frictional resistance effect of grinding charge material, produce illustrated anticlockwise rotation along self axis.The end face that bearing block [7] matches with main shaft channeled disks [10] vertically is an arc surface; when bigger difficult-to-grind materials particle or material being arranged when grinding ring [3] axial distribution variable thickness causes in the grinding machine, propellers [5] can be done illustrated oscillating motion around himself symmetrical centre.The lower surface of bearing block [7] radially is pressed on the rubber spring [6] along the guide groove end face of main shaft channeled disks [10], when thickness of feed layer in the grinding machine changes, propellers [5] can along main shaft channeled disks [10] radially do illustrated radial motion, to adapt to the variation of thickness of feed layer in the grinding machine.Therefore, propellers [5] can produce above-mentioned three degrees of freedom of movement in grinding machine.
In the grinding machine course of work, propellers [5] contact with grinding ring [3] all the time owing to action of centrifugal force, after the grinding charge material entered grinding machine along grinding machine top diagram B direction, the main shaft channeled disks [10] of being rotated was at a high speed got rid of to the inwall of grinding ring [3] and is distributed more even.When material moved downward under the gravity effect, the centrifugal force of the propellers [5] of rotation generation produced extruding, shearing and abrasive action to material at a high speed, thereby material is pulverized.Under the helicla flute of propellers [5] promoted, the grinding charge material moved downward along grinding ring [3] inwall, then outside illustrated C direction discharge machine.
Because the employing conical surface connects between grinding ring [3] and the grinding ring cover [4], by top chock [1] and bolt [2] grinding ring [3] is applied adjustable compressive pre-stress, stops or has slowed down the generation of fatigue crack, thereby can prolong the service life of grinding ring [3]; In addition, because propellers [5] can produce three degrees of freedom of movement to adapt to thickness of feed layer variation and to prevent the eccentric wear of the stuck or inhomogeneous generation of stand under load of propellers [5] main shaft channeled disks [10] in, can prolong the service life of propellers [5].Thereby make grinding machine energy ordinary production, improve service life, reduce production costs.
