Abstract
The utility model discloses a grinding roller device of a vertical swing type grinding mill, which is characterized by consisting of a grinding roller, a lock nut, a sealing gasket, a grinding roller shaft, an upper gland, a tight washer, a spindle nut, an upper radial thrust cylindrical roller bearing, a vertical shaft, a grinding roller left sleeve, a grinding roller right sleeve and a lower radial thrust cylindrical roller bearing, wherein the lock nut and the sealing gasket are fixedly connected on the grinding roller shaft; the upper gland is arranged on the grinding roller right sleeve; the vertical shaft is arranged in the grinding roller left sleeve by the upper radial thrust cylindrical roller bearing and the lower radial thrust cylindrical roller bearing; and the upper radial thrust cylindrical roller bearing and the lower radial thrust cylindrical roller bearing are fixedly connected at both ends of the vertical shaft by the spindle nut and the tight washer. The grinding roller device can completely convert the centrifugal force into the grinding force, makes a grinding zone constant, improves the working efficiency and has a simple structure.
Description
Technical field
The utility model relates to a kind of abrasive dust part of appliance of nonmetallic ore, specifically is a kind of Burnisher apparatus of upright pendulum type ring roll pulverizer.
Background technology
In the formula that the dangles flour mill: grinding roller in Burnisher apparatus cover is for the monotubular formula, and the grinding roller axle is contained in the monotubular grinding roller cover through two bearings, and a grinding roller is equipped with in the lower end of grinding roller axle.There is lateral aperture side, grinding roller set upper side; Horizontal axis tam is contained in the lateral aperture; And be fixed on grinding roller with a tight fixed bolt and put; Each Burnisher apparatus is horizontally hinged on two yokes of plum blossom rack device through two rubber sleeves on horizontal axis tam and the horizontal axis tam, and the plum blossom frame can divide 2,3,4,5,6 groups according to the difference of type.Two yokes are arranged on every group.This structure has the defective one of which of following two aspects: centrifugal force can not 100% change into abrasive power (because of Burnisher apparatus when pin joint is swung; Overcome the frictional force on horizontal axis tam and the rubber sleeve, thereby the abrasive power of passing to Burnisher apparatus by central shaft is less than centrifugal force).Its two: milling zone non-constant (not parallel because of grinding roller axle and central shaft, grinding roller and bull ring have an angle).
The utility model content
The purpose of the utility model is for overcoming the deficiency of prior art, and a kind of Burnisher apparatus of upright pendulum type ring roll pulverizer is provided, and this device can be converted into abrasive power with centrifugal force 100%, makes milling zone constant.
The technical scheme that realizes the utility model purpose is:
A kind of Burnisher apparatus of upright pendulum type ring roll pulverizer; By grinding roller, locking nut, seal receptacle, grinding roller axle, upper press cover, tight packing ring, mainshaft nut, go up centripetal thrust force cylinder roller bearing, vertical shaft, grinding roller left side cover, the right cover of grinding roller, the centripetal thrust force cylinder roller bearing is formed down; Locking nut and sealing gasket are connected in grinding roller on the grinding roller axle; Upper press cover is arranged on the grinding roller right side and puts; Vertical shaft is arranged on a grinding roller left side through last centripetal thrust force cylinder roller bearing and following centripetal thrust force cylinder roller bearing and puts, and last centripetal thrust force cylinder roller bearing and following centripetal thrust force cylinder roller bearing are fixed in the two ends of vertical shaft by mainshaft nut and tight packing ring.
Described grinding roller cover is left and right bitubular grinding roller cover, and the interior two bearings up and down of the left side cover in the bitubular grinding roller cover is the centripetal thrust force cylinder roller bearing of particular design.This bearing comprise get on the right track, lower railway and cylindrical roller.Last lower railway is corresponding each other arc surface.Type groove baffle plate is colluded in the arc surface lower end of getting on the right track, and its effect is to prevent the cylindrical roller landing.Be uniform-distribution with many cylindrical rollers on the arc surface of lower railway, cylindrical roller upper end is close on the arc surface that gets on the right track, and moves along fixed track colluding under the type groove baffle effect.
When can bearing very big axial load, said centripetal thrust force cylinder roller bearing also can bear big radial load.Roller does not have retainer, and the lower end of roller is exposed, and orbital plane is an open type outside, is convenient to the extraneous dust that gets into bearing and discharges with the roller rotation, and bearing need not to lubricate and also need not seal.
Described vertical shaft is fixed, with the equipped upper end bearing of vertical shaft go up circle and with the following circle of the equipped bottom end bearing of vertical shaft be friction tight.
When the host center axle rotated, Burnisher apparatus rotated around vertical shaft under action of centrifugal force, makes grinding roller act directly on the bull ring, and promptly centrifugal force 100% changes into abrasive power.Because of grinding roller rotates around vertical shaft, grinding roller contacts with bull ring is parallel again, and milling zone is constant.
The utility model has the advantages that: this Burnisher apparatus can be converted into abrasive power with centrifugal force 100%, makes milling zone constant, has improved operating efficiency, and simple in structure.
Description of drawings
A kind of Burnisher apparatus structural representation of Fig. 1 the utility model;
Among the figure: 1. 12. times centripetal thrust force cylinder roller bearings are overlapped on centripetal thrust force cylinder roller bearing 10. vertical shafts 11. a grinding rollers left side on the right cover of grinding roller 2. locking nuts 3. sealing gaskets 4. grinding roller axles 5. grinding rollers 6. upper press covers 7. tight packing ring 8. mainshaft nuts 9..
The specific embodiment
Consult Fig. 1; The Burnisher apparatus of a kind of upright pendulum type ring roll pulverizer of the utility model; By the right cover of grinding roller 1, locking nut 2, seal receptacle 3, grinding roller axle 4, grinding roller 5, upper press cover 6, tight packing ring 7, mainshaft nut 8, go up centripetal thrust force cylinder roller bearing 9, vertical shaft 10, grinding roller left side cover 11, centripetal thrust force cylinder roller bearing 12 is formed down; Locking nut 2 is connected in grinding roller 1 on the grinding roller axle 4 with sealing gasket 3; Upper press cover 6 is arranged on the right cover 5 of grinding roller; Vertical shaft 10 is arranged in the grinding roller left side cover 11 through last centripetal thrust force cylinder roller bearing 9 and following centripetal thrust force cylinder roller bearing 12, and last centripetal thrust force cylinder roller bearing 9 and following centripetal thrust force cylinder roller bearing 12 are fixed in the two ends of vertical shaft 10 by mainshaft nut 8 and tight packing ring 7.
