Definitions

  • the invention relates to a drum washing machine with a washing drum rotatably mounted about a horizontal axis in a star-shaped support frame, which can be driven via a gear by a motor attached to an arm of the support frame, which is connected to a swing arm connected to the drive-side motor bearing plate Swinging bearing eye of the support frame arm is mounted so that it can oscillate within limits and is fastened to the support frame arm in a curved elongated hole by means of a screw fastening on the drive-side motor end shield.
  • Such a drum washing machine is known from DE-OS 31 32 211.
  • this solution has advantages in terms of the transmission and propagation of noises which the drive motor necessarily causes.
  • this solution is more efficient compared to other types of fastening with several auxiliary components.
  • this fastening solution places high demands on the screws to be used for fastening the drive motor. Since the motor belongs to the vibrating unit of a drum washing machine and has a relatively high mass, the alternating acceleration forces put a considerable strain on the screw heads. Equally high loads also occur during transport impacts that act in the direction of the drum axis of the washing machine. Shocks acting transversely to the drum axis load the screws.
  • the invention has for its object to design the mounting area in the known drum washing machine so that the aforementioned loads do not affect the screw heads, but the cast parts (support arm and motor end shield).
  • this object is achieved in that the motor end shield engages with its screw fastening from one side of the support frame arm and the swing arm from the other side.
  • the oscillating bearing consists of a bush inserted into the bearing eye and a pin attached to the oscillating arm, a particular simplification of assembly results from the fact that the motor with its oscillating arm pin can be hooked into the oscillating bearing and not during further assembly must be held more.
  • the bearing journal consists of a screw which penetrates the swing arm and the support arm. Together with a nut screwed onto the inserted threaded pin, it can ensure the secure mounting of the motor.This is particularly important if, for any reason, the fastening of the drive motor cannot be done by a single screw alone - namely the screw mounting on the motor end shield can be.
  • the support frame arm has a guide finger below its elongated hole, which supports the drive-side motor end shield in the mounted position of the motor, far from the screw fastening .
  • the tub 1 of a washing machine is usually fastened in a star-shaped support frame 2, in the hub 3 of which the bearing journal of a laundry drum is rotatably mounted in a manner not shown here.
  • a foot-like extension 5 is attached to one of the downward-pointing arms of the support frame 2, namely on the arm 4, which extends beyond the outer contour of the tub 1.
  • the foot-like extension 5 has two fastening points, a pivot bearing eye 6 and an arcuate elongated hole 7.
  • the pivot of a pivot arm 8 is suspended in the pivot bearing eye 6 and is a fixed component of the drive-side end plate 9 of the drive motor 10.
  • the motor 10 can be pivoted about the pivot bearing eye 6, so that a belt (not shown) which wraps around the drive pinion 12 of the motor 10 can be tensioned.
  • the motor end shield 9 rests in the region of the end of the foot-like extension 5 carrying the slot 7 from behind on the support frame arm 4, while the swing arm 8 of the end shield 9 grips around the foot-like extension 5 and from the front side of the Support frame arms 4 attacks.
  • the motor end shield 9 forms, with its swing arm 8, a clasp, as it were, around the foot-like extension 5.
  • the swing arm 8 is integrally connected to a bearing pin 13 which is directed forward from the rear of the tub and engages in the bearing eye 6.
  • the bearing eye 6 is also reinforced with a rubber-metal bushing 14, the inner metal bushing of which has a sliding fit with the pin 13.
  • the swing arm 8 can have an inserted screw with a threadless sliding shaft at this point, which can be secured from the front side of the support arm 4 with a nut.
  • a screw is also provided for fastening the end of the foot-like extension 5 carrying the elongated hole 7 in the screw thread 11 of the motor end shield 9.
  • the end of the foot-like extension 5 containing the elongated hole 7 also carries a guide finger 15.
  • This guide finger 15 extends up to the annular area of the end shield through which the motor shaft 16 with its pinion 12 attached to the front extends outwards protrudes.
  • the distance of the ring surface of the end shield 9 which wraps around the motor shaft 16 to the front surface 18 of the guide finger 15 is intended to clarify that this ring surface should lie as closely as possible to the front surface 18 of the guide finger 15, but in no case a greater distance from the front contact surface of the Stubs for the thread 11 may have, as the distance between the surfaces 17 and 18 on the foot-shaped extension 5.
  • both the foot-like extension 5 and the swing arm 8 are cranked so that the contact surfaces on the swing bearing eye and on the screw fastening are changed.
  • this spatial arrangement can also be achieved in that either only the foot-like extension 5 or only the swing arm 8 is cranked accordingly.
  • the guide finger 15 can also have a different shape and / or engage at a different location on the motor end shield 9.
  • the shape of the motor mounting according to the invention prevents excessive loads on the screw heads in the event of impacts on the vibrating unit. Shocks from the front are partially absorbed by the pin attachment of the swing arm 8, while shocks from behind on the vibrating unit are absorbed by the contact surfaces between the motor end shield 9 and the foot-like extension 5.
  • the rubber-metal bushing shown in FIG. 2 dampens transmissions of vibrations generated by the drive motor 10 to the unit. An additional simplification of the assembly is given by the swing arm pivot designed according to FIG. 2, because only one screw has to be tightened for fastening the motor.
