Definitions

  • the present invention concerns the field of laundry washing machines.
  • the present invention refers to bearing assemblies for washing drums in laundry washing machines.
  • laundry washing machines both "simple” laundry washing machines (i.e. laundry washing machines which can only wash and rinse laundry) and laundry washing-drying machines (i.e. laundry washing machines which can also dry laundry), is widespread.
  • laundry washing machine will refer to both a simple laundry washing machine and a laundry washing-drying machine.
  • Laundry washing machines generally comprise an external casing, or cabinet, provided with a washing tub rotatably supporting a rotatable perforated drum where the laundry is placed.
  • the drum is preferably rotated by means of a shaft and a motor unit coupled thereto.
  • a motor unit of known type comprises an electric motor usually arranged close to the tub and connected to the shaft by means of a mechanical transmission device, preferably by means of a belt that drives a pulley coupled to the shaft.
  • Another motor unit of known type comprises a so called “direct drive motor”.
  • the motor unit preferably comprises a stator which is preferably fixed to the rear wall of the tub and a rotor which is directly connected to the shaft so that the drum can be rotated without using further mechanical transmission devices.
  • the shaft is preferably rotatably supported by the tub through a bearing assembly.
  • US7,862,871B2 discloses a bearing assembly of known type.
  • the document discloses a laundry washing machine including a washing tub having a plastic injection-molded wall wherein the bearing assembly is provided for supporting the shaft thereto.
  • the bearing assembly comprises a plastic member, moulded with said wall, which is, in turn, injection-moulded onto a bearing shell apt to rotatably receive the shaft.
  • US8,590,347B2 discloses a bearing assembly of known type.
  • the document also discloses a laundry washing machine including a washing tub having a plastic injection-molded wall wherein the bearing assembly is provided for supporting the shaft thereto.
  • EP 1 688 525 A1 discloses a further bearing assembly of the known type, comprising a bearing housing that is connected through bolts to a bracket that is connected to the rear surface of the tub through further bolts.
  • the bearing assembly comprises a housing sleeve, moulded with said wall, which is, in turn, moulded onto two rolling bearings apt to rotatably receive a support shaft of the drum.
  • the bearing assembly represents a critical part of a laundry washing machine since it must withstand high mechanical stresses, for example vibrations, in particular during the centrifugal step of a laundry washing cycle.
  • Mechanical stresses are mainly due to rotation of the soaked laundry inside the drum and therefore strongly depends on the drum rotation speed and/or on the amount of load which is inserted into the drum and/or the imbalance state of the load inside the drum.
  • bearing assemblies are strictly linked to the type of laundry washing machine, in particular to the maximum laundry load amount which can be loaded, known as capacity, and/or to its maximum rotation speed.
  • a bearing assembly for a laundry washing machine of higher capacity requires bulky and/or stronger components than a laundry washing machine with lower capacity (for example a 6kg medium load capacity laundry machine).
  • a bearing assembly for a laundry washing machine with high maximum rotation speed (for example 1500 rpm) requires bulky and/or stronger components than a laundry washing machine with lower maximum rotation speed (for example 1000 rpm).
  • the bearing assemblies according to the known technique nevertheless, revealed some drawbacks.
  • a drawback posed by the bearing assemblies of the known art and/or the laundry washing machines having such bearing assemblies lies in that they require high manufacturing costs.
  • the object of the present invention is therefore to overcome the drawbacks posed by the known technique.
