Abstract
A ball mill comprises an upper and a lower box, the upper cover of the upper box is provided with a refueling checking hole, the lower box is provided with an oil discharging hole, a supporting roller, a bearing and a shaft which are provided together on the supporting roller and are located within the box, the hollow shaft is supported by the supporting roller, with a supporting angle of 60-80 degree; the surface of the hollow shaft is provided with wear resistant sleeve; the outer layer of the supporting roller is provided with a wear resistant layer. The utility model is free from refueling constantly and has a reasonable structure and a low oil temperature; the utility model is convenient to produce and maintain and has advantages of high rigidity, wearing resistance, low noise and long service life.
Description
The utility model relates to a kind of ball mill, belongs to mine grinding machinery technical field.
The ball mill that China produces mostly is Soviet Union's technology of introducing the fifties, the product structure complexity, and its carrying roller and hollow diameter of axle extexine are not done surface treatment, hardness is low, and service life is short, temperature rise, oil consumption height, power consumption is big, cost of repairs height, the needs of incompatibility manufacturer.Shandong Yantai Metallurgy Mine Machinery Factory uses heavy caliber rolling bearing replacement sliding bearing for many years instead, and its weak point is: the limited output of bore is low, and cost is too high not susceptible to user acceptance.
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of hollow diameter of axle and carrying roller skin that wear-resistant sleeve or wearing layer are housed, and is rational in infrastructure, the ball mill of long service life.
The purpose of this utility model is achieved in that and comprises upper and lower casing, cover on the upper box to be provided with and refuel and inspection opening, lower box is provided with drain oil, carrying roller, bearing and axle are installed on the carrier roller frame together, place in the casing, its structural feature is: quill shaft supports by carrying roller, and the support angle of carrying roller general name and quill shaft is 60-80 °; Wear-resistant sleeve is equipped with on the surface of quill shaft; The skin of carrying roller is provided with wearing layer.
Described carrying roller is set to 2-4, and carrying roller general name and carrying roller overcoat fit together.
Described wear-resistant sleeve also can be the wearing layer of cure process.
Adopt said structure, added wearing layer, improved the surface hardness and the abrasion resistance of ball mill quill shaft and carrying roller, and then prolonged its service life to quill shaft and carrying roller.
Compared to existing technology, the utlity model has following advantage:
1, do not need frequent oiling, rational in infrastructure, the oil temperature is low, makes simple, easy to maintenance.
2, the hardness height, wear-resisting, noise is low, long service life.
3, power consumption is little, and 20-30% can economize on electricity.
The explanation of accompanying drawing drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model 4 idler structure schematic diagrames
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is the improvement of existing ball mill, has developed wearing layer quill shaft and carrying roller, is the alloy tile structure that a ball mill Idler bearing replaces sliding bearing, makes abrasion resistance and hardness obtain the reliable technique assurance.It is by last lower box 2,3, and carrying roller general name, carrier roller frame 9 are formed.The skin of the diameter of axle of its quill shaft 4 is equipped with wear-resistant sleeve 5, and wear-resistant sleeve 5 also can be the cure process layer.The carrying roller general name is made up of roller carrier shaft 10, carrying roller 7,2-4 cover bearing.Carrying roller 7 can be established 2-4, and Fig. 1 of the present utility model is 2 carrying roller support hollow axle 4 schematic diagrames.When ball mill is large scale structure, need to use structure as four carrying roller support hollow of Fig. 2 axle 4.The skin of its carrying roller 7 also is with wear-resistant sleeve or wearing layer 6.Described wearing layer 5,6 is through cure process, also bearing steel overcoat.It mainly acts on is protection quill shaft 4 and carrying roller 7, to prolong its service life.Two carrying rollers 7 are installed on the carrier roller frame 9 in the casing together with roller carrier shaft 10, bearing, and two carrying roller general name together support quill shafts, 4 its strut angles are the 60-80 degree.Carrying roller general name and carrying roller shell fit together, and wherein, bearing is fixed on axle and the shell with locknut or jump ring.Casing is by upper box 2, and lower box 3 is formed, and lubricating oil is housed in the casing.Cover on the upper box 2 to be provided with and refuel and inspection opening 1.The bottom of lower box 3 is provided with drain oil 8.
During work, 4 rotations of carrying roller general name support hollow axle realize goal of the invention.
Claims (4)
1, a kind of ball mill comprises upper and lower casing, covers on the upper box and is provided with the oiling inspection opening, and lower box is provided with drain oil, and carrying roller, bearing and axle are installed on the carrier roller frame together, place in the casing, it is characterized in that:
A, quill shaft support by carrying roller, and the support angle of carrying roller general name and quill shaft is 60-80 °;
