Abstract
The utility model relates to a center driving ball mill which comprises a base, a barrel and a driving device for driving the barrel to rotate, wherein two ends of the barrel are respectively a feeding end and a discharging end; the feeding end is provided with a support shaft; the discharging end is provided with a driving shaft; the support shaft and the driving shaft are respectively installed on the base by a bearing; the driving device comprises a motor and a reducer; the output shaft of the motor and the input shaft of the reducer are connected by a first coupler; and the output shaft of the reducer is connected with the driving shaft in a driving mode by a second coupler. The center driving ball mill adopts the center driving mode instead of the edge driving mode, so that a driving system is improved, the energy-saving effect is remarkable, and the situation that a gearwheel and a pinion are difficult to keep better lubrication under the opened overall situation is avoided. The center driving ball mill has long service life and is convenient to overhaul and maintain.
Description
Technical field
The utility model relates to a kind of center transmission ball mill.
Background technology
Ball mill is after material is broken, the key equipment of pulverizing again, be widely used in industry grinding industries such as ore dressing, building materials, chemical industry, ball mill comprises cylindrical shell, input and output material hollow shaft and the bistrique of level, and cylindrical shell is microscler cylinder, in the tube abrasive body is housed, cylindrical shell is the steel plate manufacturing, and inwall is fixed by steel abrasion-proof backing block and cylindrical shell, and abrasive body is generally the steel ball, and pack in the tube middle-size and small-size ball mill into by different-diameter and certain proportion.Existing ball mill adopts the edge transmission of open gear pair, the ball mill end is provided with gear wheel, also has the drive unit that the drive ball grinding mill barrel rotates, this structural volume is big, mechanical efficiency η=0.86～0.90, center transmission η=0.92～0.95 that mechanical transmission fields is commonly used, both differ 5%, therefore adopt the energy consumption of edge transmission higher.The exposed gear of edge transmission is in and is difficult to the strict gear cover that seals, and is difficult to keep good lubrication, and dust intrusion wearing and tearing are quite violent, and its life-span is shorter, and the dispersion of the part of edge transmission, and fuel feeding point and checkpoint are bigger, operation, inspection difficulty etc.
The utility model content
The technical problems to be solved in the utility model is: for the deficiencies in the prior art, the utility model provides a kind of center transmission ball mill, adopts the center kind of drive to avoid edge transmission energy consumption height, inefficient technical problem.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of center transmission ball mill, comprise the drive unit that base, cylindrical shell and driving cylindrical shell rotate, the two ends of cylindrical shell are respectively feed end and exhaust end, feed end has back shaft, exhaust end has driving shaft, back shaft and driving shaft are installed on the base by bearing respectively, described drive unit comprises motor and decelerator, the output shaft of motor is connected by first shaft coupling with input shaft of speed reducer, and the output shaft of described decelerator is in transmission connection by second shaft coupling and driving shaft.
The beneficial effects of the utility model are, transmission ball mill in center of the present utility model changes original edge kind of drive, the employing center kind of drive, improve transmission system, mechanical efficiency is higher, and energy-saving effect is remarkable, has avoided large and small gear to be difficult to keep the situation of good lubrication under open overall situation, long service life, repair and maintenance is convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of center transmission ball mill most preferred embodiment of the present utility model.
Among the figure: 1. base, 2. cylindrical shell, 21. feed ends, 22. exhaust ends, 3. back shaft, 4. driving shaft, 5. motor, 6. decelerator, 7. first shaft coupling, 8. second shaft coupling.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Figure 1, the most preferred embodiment of transmission ball mill in center of the present utility model, comprise base 1, cylindrical shell 2 and drive the drive unit that cylindrical shell 2 rotates, the two ends of cylindrical shell 2 are respectively feed end 21 and exhaust end 22, feed end 21 has back shaft 3, exhaust end 22 has driving shaft 4, back shaft 3 and driving shaft 4 are installed on the base 1 by bearing respectively, drive unit comprises motor 5 and decelerator 6, the output shaft of motor 5 is connected by first shaft coupling 7 with the power shaft of decelerator 6, and the output shaft of decelerator 6 is in transmission connection with driving shaft 4 by second shaft coupling 8.
The utility model replaces the transmission of conventional ball mill size gear edge with the center transmission, and all parts all are positioned on same axle or same the paralleling to the axis.Mechanical efficiency is higher, and energy consumption is lower.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
