Abstract
The utility model provides a magnetic powder brake with circulation water cooling structure, which is composed of a still rotor, a moving rotor, an excitation coil, a magnetic yoke, and magnetic powder, which is mainly characterized in that the utility model adopts a still and moving rotor structure, the still rotor and the moving rotor butt joint, the still rotor is arranged in the inner of the moving rotor, the magnetic powder is arranged in the working gap between the still and the moving rotor, and a circulation water cooling structure is arranged in the inner of the still rotor. The utility model has the advantages of large cooling water room and good cooling effect on the circulation water cooling structure is arranged in the inner of the still rotor.
Description
The utility model relates to a kind of magnetic powder brake.Magnetic powder brake heats up owing to the magnetic that is magnetized glues to rub mutually when work, influences service life of a machine.In order to guarantee the normal operation of machine, life-saving must be taked effective cooling method.It is the best way that method commonly used has natural cooling, forced air cooling method and water cooling, water cooling.A kind of water-cooled magnetic powder brake of domestic manufacturer's production at present is that the yoke design that will comprise field coil becomes full-closed structure (as Fig. 1), and a tank is set at the middle part, and cooling water enters from a side, discharges from opposite side along tank.This design is very narrow because of its tank, and cooling range only is a very narrow area around the tank, and cooling effect is not good, and the appearance temperature is still higher.In addition, also have the cooling water channel complex process, difficulty of processing is big, and water-stop is difficult to guarantee shortcomings such as moment instability.
The purpose of this utility model is to provide a kind of magnetic powder brake of rational in infrastructure, good cooling results.
The purpose of this utility model is realized by following technological scheme: change exchange structural type, adopt quiet, moving rotor structure, with quiet rotor and the butt joint of moving rotor, quiet rotor places in the moving rotor, magnetic places the working clearance between the quiet moving rotor, and circulating water cooling structure is set in the quiet rotor.
The utlity model has following advantage:
1, owing to adopt quiet, moving rotor structure, dismounting is easy to maintenance, and quiet rotor places in the moving rotor, and magnetic structure is reasonable, can guarantee the linearity of product electric current-torque factor curve;
2, the setting of quiet, moving rotor makes the yoke that comprises field coil separate fully with the heating working surface, the phenomenon of high temperature scaling loss coil can not occur;
3, magnetic is held in the moving rotor, and moving rotor can be uniformly distributed in working surface with magnetic when rotating, and guarantees the moment stability of product;
4, circulating water cooling structure is set in the quiet rotor, cooling water chamber is big, good heat dissipation.

Fig. 2 is the utility model structural drawing;
Fig. 3 is circulating water cooling structural drawing;
Fig. 4 is a dividing plate A planimetric map;
Fig. 5 is a dividing plate B planimetric map.
Among the figure: the 15-overflow hole of 14-water inlet
Embodiment:
The utility model mainly is made up of quiet rotor (3), field coil (7), moving rotor (8), yoke (6) and magnetic, and quiet rotor (3) and moving rotor (8) adopt docking mode, and quiet rotor places in the moving rotor.Quiet rotor is by being bolted on the end cap (4), and moving rotor (8) is assemblied on the input end cap (10) by bearing (11,12).That magnetic places is quiet, the working clearance (9) between the moving rotor, and by sealing cover (5) sealing, when input shaft was driven, magnetic can be uniformly distributed in working surface, and after the energising, bonding state is stable, thereby guarantees that product performance are stable.
The utility model is provided with circulating water cooling structure in quiet rotor (3).As shown in Figure 3, the right of quiet rotor steel plate (13) welded seal, inner chamber is a hydroecium, communicate with hydroecium by spiral marking connection inlet tube and outlet tube (1,2) on the quiet rotor left side, in order to form circulating water, hydroecium is separated by some disk spacers, has the overflow hole of diverse location on the dividing plate, cooling water is guided to by intake pipe to press behind the water-dividing chamber on the limit of keeping right and is flowed to circulation shown in the arrow from the water outlet venting, takes away heat.
Claims (2)
1, a kind of magnetic powder brake with circulating water cooling structure, mainly form by quiet rotor, moving rotor, field coil, yoke, magnetic etc., it is characterized in that this break adopts quiet, moving rotor structure, described quiet rotor and the butt joint of moving rotor, quiet rotor places in the moving rotor, that magnetic places is quiet, the working clearance between the moving rotor, is provided with circulating water cooling structure in the quiet rotor.
2, break according to claim 1, it is characterized in that circulating water cooling structure is that inner chamber by quiet rotor welds the hydroecium that surrounds with steel plate, hydroecium is separated by some disk spacers, has overflow hole on the dividing plate, also has inlet tube and outlet tube to communicate with hydroecium on the left side of quiet rotor.
