Two, run

(1), open end can door 102, washing clothes etc. is put into and puts into rolling cylindrical shell 108, close cylinder door 102;

(2), on control manipulation box 130 panel set washing procedure, open water intaking valve 132, running water through outer water supply pipe 123 and interior antidetonation water inlet pipe 133, is injected in steel ladle 103 successively;

(3), when the motor is energized, the moment of torsion that electromagnetic force produces is by the axle head spline 49 on machine shaft 40, and the hub splined hole 94 that turns turned on hub 90 through cylinder passes to cylinder rear board 181, drives whole rolling cylindrical shell 108 to rotate;

(4), the shape of washing clothes and volume be irregular caused vibrations, and part vibrations obtain weakening because rolling cylindrical shell 108 inwall bilateral symmetry is configured with counterweigh ring 199; Another part vibrations obtain weakening by union piston in combination weakening part;

(5), stage wash is complete, can open or close draining control valve 127 by draining control line 135.

Three, the utility model has following substantive distinguishing features and progressive effect:

(1), the squirrel-cage water-cooled machine assembly 110 of the utility model core component and the syndeton of rolling cylindrical shell 108 are: have 1.22 to 1.24 millimeters of gaps between the member through-hole 804 of described wheel frame member 80 and the rotating shaft of described machine shaft 40 overhanging section 46, organic sealing assembly 48 between the component stepped hole 84 of described wheel frame member 80 and the rotating shaft of described machine shaft 40 overhanging section 46, between described component stepped hole 84 and described member through-hole 804, organic envelope dismantles groove 808, is convenient to the machine sealing assembly 48 described in specific purpose tool dismounting and change.

Front shroud 20 among among squirrel-cage water-cooled machine assembly 110 is arranged wheel frame member 80, shared all moment of flexure loads, made machine shaft 40 only bear pure torsion.Prop up to hold round between 89 and component for adjusting ring 82 cylindrical have high accuracy axiality in order to ensure the outer bearing on wheel frame member 80, outer bearing outside component flange 87 being propped up the axiality held round between 89 and component for adjusting ring 82 cylindrical is that the error of 100 millimeters of unit sizes is less than or equal to 0.001 millimeter.Said structure achieves machine shaft 40 and fore bearing 25 and rear bearing 35 need and bears pure torsion, and the radial load that self imbalance of rolling cylindrical shell 108 produces react to cylinder turn hub 90 be can completely bear by no inner-ring bearing 60, only act on wheel frame member 80, the rotating shaft on completely isolated machine shaft 40 bears radial load for overhanging section 46; Meanwhile, because wheel frame member 80 global shape belongs to hollow short tube, therefore structural rigidity is superpower, can bear larger radial load.Both combine, and the utility model achieves and can do compact by whole motor size, can bear larger radial load again, run more reliable, thus extend the service life of motor.

(2), have employed in squirrel-cage water-cooled machine assembly 110 between motor housing 10 and front shroud 20 and rear end cap 30 has to link up a part 17 respectively, make the sealing of cooling water channel no longer too rely on end face to be close to, thus reduce the planarity requirements to the inner side end of end cap, the end face of support, thus reduce difficulty of processing and to quality of motors requirement.

(3), weakening assembly is arranged on the rear back side of the rotary parts such as steel ladle, reduces the center of gravity of the rotary parts such as steel ladle; Tension and compression union piston dashpot 161 and pressure draw the double-piston chamber compound action of union piston dashpot 169, alternately bearing pressure or pulling force; Vibration amplitude reduces.

The pressure that motor perforation less than 185 on upright plate 180 has intersection dislocation to arrange draws flap seat 167 and tension and compression base 163; There is vertical flanged plate 196 on rear side of bedplate 190, have inside vertical flanged plate 196 and intersect the pressure that dislocation arranges and to undercut seat 168 and tension and compression flap seat 162,

Pressure to undercut on seat 168 and rotation can be fixed wtih pressure and draw union piston dashpot 169 1 termination, and tension and compression flap seat 162 rotation can be fixed wtih tension and compression union piston dashpot 161 1 termination; Pressure draws another termination of union piston dashpot 169 rotation can be fixed on pressure and to draw on flap seat 167, and another termination of tension and compression union piston dashpot 161 can rotation be fixed on tension and compression base 163;

Above-mentioned Vibration eliminating structure makes to reduce as the disk rotor frame electric machine assembly 110 of vibration source and the overall center of gravity of steel ladle 103 and rolling cylindrical shell 108, save the upper lower spring weakening space of the rotation focus in conventional washer, show through Experimental comparison: height of C.G. reduces 88.5 millimeters than similar type;

Union piston in combination weakening part stress is divided into two kinds:

The first state: when being cavity in steel ladle 103 and rolling cylindrical shell 108, the load center of gravity on upright plate 180 presses close to upright plate 180 or deflection disk rotor frame electric machine assembly 110.At this moment, tension and compression union piston dashpot 161 subjects tensile load, and the closed gas in tension and compression first chamber 111 in tension and compression union piston dashpot 161 expands, the closed gas compression in tension and compression second chamber 112 in tension and compression union piston dashpot 161; Pressure draws union piston dashpot 169 to subject pressure load, and pressure draws the pressure in union piston dashpot 169 to draw the closed gas in the first chamber 911 to compress, and pressure draws the pressure in union piston dashpot 169 to draw the closed gas in the second chamber 912 to expand.

The second state: when loading onto washing clothes in steel ladle 103 and rolling cylindrical shell 108 and filling water, load center of gravity on upright plate 180 shifts to steel ladle 103 and rolling cylindrical shell 108 side away from upright plate 180, at this moment, tension and compression union piston dashpot 161 shares a part because reversing the pressure load produced, and pressure draws union piston dashpot 169 to share a part because reversing the tensile load produced; Owing to loading onto washing clothes in rolling cylindrical shell 108, suffered by the tension and compression union piston dashpot 161 in the second state is still tensile load with joint efforts, and pressure draws still be pressure load making a concerted effort suffered by union piston dashpot 169.

No matter be pressure load or tensile load, tension and compression union piston dashpot 161 and pressure draw union piston dashpot 169 can rely on the two closed cavities of self, alternately bearing pressure or pulling force.Union piston in combination weakening part can both play the effect of weakening, guarantees the utility model even running.

A pressure particularly on upright plate 180 back side is drawn flap seat 167 and two tension and compression bases 163 to present isosceles equilateral triangle and is arranged, and undercut seat 168 and two tension and compression flap seats 162 of a pressure inside vertical flanged plate 196 present isosceles del and arrange, both combine, ad hoc structure provides not only firm but also to possess center of gravity minimum to steel ladle 103, make steel ladle 103 can press close to plane on bedplate 190 as much as possible.Show through Experimental comparison: vibration amplitude decreases 8 percent eight.

(4) housing flange 122 on shell front panel 104 opening on, described shell body 101 is provided with described cylinder door 102 just above, bucket flange 121 on described steel ladle 103 opening just above and airtightly between the back side after described housing flange 122 is connected with bellow seal ring 124 bellow seal ring 124, had not only been accomplished static sealing but also can have been born the vibrations of certain amplitude of oscillation.

(5), under the synergy of the upper spring 230 of the utility model among dual spring weakening wheel assembly 120 and lower spring 250 and plane bearing ball 277, can in movement arbitrarily on uneven ground of jolting, weakening better effects if, and mobile specially turn to sensitive.
