Shaft stub for washing machine drum with horizontal

Axis of rotation

On τοπ washing machines with a horizontal axis of rotation, stubs are provided on both sides, which are hooked into the corresponding bearings of the washing machine! // ground Washing drums made of Ohrom-Siickel steel sheet to prevent corrosion. For the same reasons, it seems expedient »to also manufacture the shaft stubs of these washing drums from Ohrom-Siickel steel» because Ghrom-Hickel steel is very expensive * would massive shaft stubs from Chromi? ielcel steel ien price wash rammeln increase aussergeviöhnlich * the weight of such washing drums would be enlarged by massive fur stumps. Finally, be massive Y / elle stumps from Ghrom-Lickel steel hard work and are therefore affordable for a Mass production unsuitable.

With the fire, these deficiencies become complete removed that stub shaft for the barrel drums in the form of a tin made of sheet metal, preferably Chroia-Hickel sheet steel be sucked. As a result, the price and the dish are greatly reduced and you can as a result without further high-quality corrosion-resistant sheet metal

turn, even if this is more expensive than in the unit of weight normal construction steel, since a much smaller amount of material is "required" than with massive "stumps". The manufacturing costs are also reduced considerably, since there is no machining and instead one dimensionally accurate, non-cutting deformation can be used · The production in large numbers prepares as a result no difficulties.

I ¹ Various options are available for the formation of the new shaft stumps. One of the possibilities is that the bushing is designed as an independent part and is attached to the front wall of the washing drum with your hand by spot welding or the like. However, the sleeve can also be drawn in one piece with the end wall of the drum;

With certain types of washing machine it is advisable to to releasably couple the stub shaft of the drum to the drive axle, to remove the drum as required and then again to be able to use. The clutch should be as automatic as possible solved or completed, to bsim taking out and Inserting the drum to save additional hand movements A driver is therefore used on the stub shaft of the drum, in a corresponding recess of the axis of rotation the washing machine intervenes. realized in that a rectangular cutout is provided in the middle of the end face of the sleeve, into which a driver bent from chrome Uickel sheet steel is used, which can engage in a corresponding recess of the axis of rotation. Also these special shaft stumps with drivers are light, cheap and easy to manufacture, since they only require thin sheets and massive parts completely make superfluous
