Abstract
The invention relates to a press roller of a water-cooling electric road roller driven directly by a brushless and toothless direct current motor. The press roller is connected with end covers of the two ends so as to form a shell of the press roller, a rotor is arranged at the inner side of the roller wall, a central shaft is arranged on the end covers of the two ends by bearings, and an inner stator is arranged on the central shaft; the inner stator includes a skeleton and a coil winding, and a water inlet and a water outlet are arranged on the end cover and is screwed tightly by a seal plug; a hollow shaft with a hole is arranged at one side of the central shaft, a wire passes the hollow hole to supply power to the stator and the structure is sealed with glue to prevent the invasion ofwater. The invention has the advantages that the press roller consumes electric energy and is low in price; the adopted electric motor is simple in structure, long in service life and is maintenance-free and highly efficient; the inside of the press roller is injected with water, therefore, the inertia is small for startup or stop and the water can be drained during the transportation to considerably reduce the weight of the press roller, and the water in the press roller can cool the electric motor.
Description
Technical field
The present invention relates to a kind of ballastroller roller, relate in particular to a kind of water cooled electrodynamic ballastroller roller that directly drives based on brushless gearless motor, this nip drum can be used to be installed on power-actuated road roller.
Background technology
The road roller that is generally used for flattening the road surface uses the solid nip drum of fuel engines, and there is following defective in this technology:
1, because petroleum resources are limited, fuel price goes up, and diesel oil puts on short allowance, and uses diesel-fuel price higher.
2, it is more expensive to compare the diesel engine price with motor.
3, diesel engine and motor structure compared complexity, the life-span is short, and maintenance is big, and efficient is low.
4, the diesel emission amount is big, contaminated environment.
Noise was very big when 5, diesel engine was worked.
6, solid nip drum weight is big, and the inconvenience transportation is not easy to start and stop.
Summary of the invention
The objective of the invention is to, solve above-mentioned existing existing problem, provide a kind of operating noise low, the life-span is long, the water cooled electrodynamic ballastroller roller that a kind of brushless gearless direct current generator of convenient transportation directly drives.
The present invention is achieved in that the nip drum 1 and the end cap 2 at two ends connect and compose the housing of nip drum, roll the installed inside rotor of wall, the end cap at two ends is installed axis by bearing, inner stator is installed on axis, inner stator comprises skeleton and coil windings, on end cap, be provided with paddle hole, and screw by sealing-plug; One side of axis is provided with hollow shaft with holes, seals with glue after penetrating lead.
Advantage of the present invention is:
1, use electric energy, electric energy is the secondary energy sources wide material sources, and is cheap.
2, the moving price of motor is comparatively cheap.
3, electric motor structure is simple, and the life-span is long, and is non-maintaining, the efficient height.
4, use electric energy can accomplish zero-emission, electric energy is a clean energy resource.
5, the motor operating noise is extremely low.
6, nip drum internal water flooding, it is little that startup stops inertia, and during transportation water being emitted weight can greatly alleviate, and the water in the nip drum can also cool off motor.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
The specific embodiment
Describe in detail below in conjunction with accompanying drawing: as shown in the figure, the end cap 2 at nip drum 1 and two ends connects and composes the housing of nip drum, the installed inside rotor 7 of nip drum 1, the end cap 2 at two ends is installed axis 4 by bearing 3, on axis 4, inner stator is installed, inner stator comprises skeleton 5 and coil windings 6, is provided with paddle hole on end cap 2, and screws by sealing-plug 8.One side of axis 4 is provided with hollow shaft 4a with holes, seals with glue after penetrating lead.
The coil windings 6 of stator uses waterproof paint envelope curve coiled everywhere joint all to be waterproof construction.
The nip drum of rotor and road roller links together and rotates synchronously with the nip drum of road roller, this kind mode directly drives transmission mechanism-free, reduce transmission loss, eliminated the mechanical wear and the mechanical breakdown that produce by transmission mechanism, promoted the application life and the reliability of equipment greatly.
During use, whole nip drum the inside all is water-filled, and stator core just is immersed in the water.Winding above the stator core all is to use the water-proof wire coiled, and stator core and magnet piece all adopt preservative treatment.It is that motor is cooled off two is that nip drum is loaded that water in the nip drum has two effects one.The problem that motor faced under the general situation is exactly the problem of magnetic bobbin core heating, because the existence of this problem is restricting the raising of motor efficiency, the increasing of power, life-time dilatation all the time.The present invention uses this mode of water-cooled to solve all problems of puzzlement slow-speed motor development at one stroke.
During transportation water is emitted, weight can greatly alleviate, and can save the fuel cost of haulage vehicle; Reduced the use cost of this kind road roller.Electronic road roller carries water pump, can fetch water nearby.
