Definitions
- the invention relates to a drive device for a front-loading washing treatment machine with a washing drum mounted at least approximately horizontally in a supporting part via a shaft, which is driven directly by a motor arranged on its rear side, the magnetizable poles of which are arranged on the rotor from the outside and which are on the stand for receiving sheet packets provided by excitation windings face each other over a minimal gap
- Such a drive device is known from DE 195 47 745 A1, in which the stand is attached to a rigid support part, which in turn is connected to the rear wall of a tub.
- the support part has a central bearing sleeve for the shaft of the washing drum and for a scar encompassing the shaft Laufers auf
- the hub carries a bell-shaped flange pointing towards the tub, on the inner circumference of which magnetizable poles are distributed.
- the magnetizable poles face each other from the outside via a minimal air gap distributed on the stator, intended to accommodate exciter windings of the stand
- the invention is based on the object of designing the drive device described at the outset in such a way that it has a simple, compact structure
- the rear wall of the washing drum has a bell-shaped depression extending in the direction of the longitudinal axis of the shaft, on the inner circumference of which facing the shaft, the magnetizable poles of the rotor are distributed, and in that the laminated core of the stand protrudes into the recess Support part are attached
- the washing drum has an indentation inwards has, the drive motor is housed inside the washing drum, so that no space for a flat motor directly driving the washing drum or for a drive belt has to be provided between the back of the washing drum and the back of the washing treatment machine ie the washer dryer or the washing machine
- a part of the support part is also the bearing sleeve for the shaft of the washing drum and serves as a stator carrier for receiving the stator packs Wash liquor used
- the bearing of the washing drum close to the center of gravity reduces the influence of unbalance or wobble.
- the supporting part is a cast metal part, for example an cast aluminum part or a cast iron part
- the motor is, for example, a reluctance motor, the magnetizable poles of the rotor being designed as layered iron sheets, or it is an electronically commutated DC motor, the poles being designed as permanent magnets
- a washing drum 1 (FIG.) Is rotatably supported by a shaft 2, which is connected to it in an essentially horizontal manner, in a bell-shaped flange 3, serving as a bearing sleeve for the shaft 2, of a rear wall 4, a tub 5.
- the flange 3 and the rear wall 4 form the supporting part for the washing drum 1
- the washing drum 1 has an opening 6 on the front Laundry can be filled.
- the laundry drum 1 has a rear wall 7, which has a bell-shaped depression 8 symmetrical to the longitudinal axis of the shaft 2.
- the depression 8 has a jacket wall 10 which connects the base 9 to the rear wall 7 and is essentially cylindrical or conical.
- the bottom 9 of the recess 8 is connected to the shaft 2 via a pin 11, for example welded to it. This is mounted via bearings 12, 13, which are ball bearings, for example, in the flange 3, which forms the bearing sleeve for the shaft 2.
- the flange 3 also forms the stand for receiving laminated cores 14 of the motor.
- the laminated cores 14 carry stator windings 15. Magnetizable poles 16 of the rotor are distributed on the inner circumference of the jacket wall 10 of the depression 8. These face the laminated cores 14 via a minimal air gap 17.
- the shaft 2 ends on the side facing away from the laundry drum 1 in a shaft end 19 secured against the bearing 13 by a spring ring 18.
- the rear wall 4 carries the flange 3 serving as a supporting part for the shaft 2 and thus for the laundry drum 1.
- an annular seal 20 with, for example, an essentially V-shaped cross section is arranged between the rear wall 7 and the rear wall 4.
- the outer tub 5 is omitted.
- the flange 3 is connected to a supporting part, which in turn is connected to the housing, for example via vibration dampers.
- the supporting part can also extend in the direction of the rear wall 4.
- the flange 3 is preferably a metal casting; it consists, for example, of cast aluminum or is an iron gray cast iron part.
- the laminated cores 14 are either designed as rings leading around the flange 3 or as circular segments.
- the poles 16 can also be embodied as rings covering the jacket wall 10 from the inside or as segments.
- the poles 16 can also be arranged axially to the laminated cores 14. In this case the poles are 16 attached to the bottom 9 of the recess 8.
- the laminated cores 14 face them, including the excitation windings, rotated by 90 ° relative to the illustrated embodiment, on the flange 3.
- the depression 8 has a smaller depth than the illustrated embodiment, but a larger diameter in the radial direction.
- the depression 8 In addition to its function for dissipating heat from the engine, the depression 8 also contributes to the sound absorption of engine noises.
- the bearing 12 is encapsulated on its side opposite the bottom 9 by a sealing ring 21.
- the laundry drum 1 is driven either by a commutated DC motor or a switched reluctance motor.
- the magnetizable poles are permanent magnets.
- a switched reluctance motor they are formed by layered iron sheets.
- the invention provides a compact drive device, an essentially horizontally mounted laundry drum 1 having a rear wall 7 with a bell-shaped depression 8.
- the laundry drum 1 is connected to the shaft 2 carrying it.
