Abstract

The utility model discloses a rolling bearing type ball mill which is used for industrial departments, such as building material, metallurgy, ore dressing, thermoelectricity, etc. An outwards adjusting mandrel toward a movable bearing 5 and an outwards adjusting mandrel toward an immovable rolling bearing 10 are used for replacing an alloy tile of an original ball mill. Because of the reduction of frictional resistance and the improvement of a lubricating method, the utility model has obvious energy-saving effect in the operation of the utility model.

Description

The rolling bearing ball mill

The utility model relates to a kind of ball mill, particularly a kind of rolling bearing ball mill.

Disclosed ball mill in the prior art, be with alloy watt supporting hollow shaft, because of its operating environment temperature height, dust concentration is big, poor lubrication, and the tile kilning accident happens occasionally, also because ball mill is the heavy load machine, the shock and vibration that produce in the running are transmitted to the caused resonance of transmission system, have aggravated the damaged of driving member and even (as wearing pin, foundation bolt etc.) fracture.This ball mill is complex structure, unreasonable not only, and power consumption is higher, and maintenance rate is higher.

The purpose of this utility model is to want to provide a kind of improved ball mill, and this ball milling function overcomes above-mentioned the deficiencies in the prior art, and is simple and reasonable, and long service life can be saved power consumption.

The technical solution adopted in the utility model is for achieving the above object, the utility model comprises feed arrangement of the prior art, charging and discharging quill shaft, cylindrical shell, two bearing blocks, gear wheel, transmission device and drawing mechanisms, its design feature is: removed water-cooling system of the prior art, one investigation mission outside the city or town axle is installed to mobile bearing on the charging quill shaft, an investigation mission outside the city or town axle is installed on the discharging quill shaft holds to movable axle not.

The utility model is owing to removed the water cooling in prior technology system, outer aligning rolling bearing has been installed on the charging and discharging quill shaft, make it simple and reasonable for structure, and can reduce vibration, reduce part mill (breaking) and decrease, improve running efficiency, its maintenance rate reduces, prolong service life, and power savings is more obvious, generally can reduce power consumption 20%.

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is that the investigation mission outside the city or town axle is to removable rolling bearing structure schematic diagram.

Fig. 3 is that the investigation mission outside the city or town axle is to not removable rolling bearing structure schematic diagram.

Following structure the drawings and specific embodiments are done further detailed description to the utility model.

The utility model embodiment is suitable for the rolling bearing ball mill of 2.4-3.2m specification, because adopt the ball mill of big specification, its economic benefit is more remarkable, about 200,000 yuan of general every Tai Niankejiezhi.

As shown in Figure 1, the rolling bearing ball mill comprises base 1 and 14, feed arrangement 2, bearing block 3, charging quill shaft 4, the investigation mission outside the city or town axle is to mobile bearing 5, cylindrical shell 7, transmission device 8, gear wheel 9, the investigation mission outside the city or town axle holds 10 to movable axle not, drawing mechanism 12, bearing block 13, discharging quill shaft 11, aligning antifriction bearing 5 and 10 top are equipped with lubricating cup 6 outside, the investigation mission outside the city or town axle is installed on the charging quill shaft 4 to removable rolling bearing 5, and with bearing block 3 supporting, the removable rolling bearing 10 of outer aligning is installed on the discharging quill shaft 11, and with bearing block 13 supporting, quill shaft 4,11 with outer aligning rolling bearing 5, ring can axially freely stretch to satisfy axial location in 10, bearing block 3 is fixed on the base 1, and bearing block 13 is fixed on the base 14.Removable rolling bearing of outer aligning 5 and outer aligning can not mobile rolling bearing 10 outer shroud 18 be spherical curve, as Fig. 2, shown in Figure 3,15 is ball; Interior ring 17 can move axially, and the cylindrical trough of belt of interior ring 16 can not move axially, to guarantee the gear normal engaged.

Claims

1, a kind of rolling bearing ball mill, comprise that feed arrangement (2), bearing block (3), charging quill shaft (4), investigation mission outside the city or town axle hold (10), discharging quill shaft (11), drawing mechanism (12), bearing block (13) to mobile bearing (5), cylindrical shell (7), transmission device (8), gear wheel (9), investigation mission outside the city or town axle to movable axle not, it is characterized in that: an investigation mission outside the city or town axle go up to be installed to mobile bearing (5) at charging quill shaft (4), to go up at discharging quill shaft (11) and an investigation mission outside the city or town axle is installed holds (10) to movable axle not.
