Definitions
- the present invention relates to a drum for a laundry washing machine, particularly of the top-loading type, said drum being provided with lateral supports of an improved type permitting said drum to be mounted in and dismounted from the laundry washing machine in a particularly simple manner.
- Known laundry washing machines of the top-loading type contain a drum mounted for rotation about a horizontal axis within a washing tub and provided with laterally projecting journals supported in the tub by means of bearings housed in respective seats formed in press-formed supports secured to the lateral walls of the tub.
- the journals themselves are connected to corresponding press-formed supports secured to the respective sidewalls of the drum, by a bolt-and conus coupling system.
- This system permits the drum to be readily mounted in and dismounted from the tub by threading the journals into the respective supports of the drums and unscrewing them therefrom, respectively.
- Laundry washing machines of this type are additionally provided with annular spacers located within the respective supports of the tub for preventing axial displacements of the bearings during rotation of the drum.
- annular seals Located finally in the seats described above are annular seals adapted to ensure radial sealing against the respective journals of the drum for preventing leakage of the laundering liquid contained in the tub.
- a drum for a laundry washing machine particularly of the top-loading type, provided with journals for its support in the washing tub, each said journal being mounted on one side in a bearing housed in a corresponding seat of a first support releasably secured to the respective lateral wall of said tub with at least one resilient sealing element being interposed therebetween, and connected on the other side, to a second support secured to the respective lateral wall of said drum and cooperating with at least one further resilient sealing element concentric therewith.
- a drum of the type defined above is characterized in that between said first and second supports there is disposed respectively a further rigid support element of annular shape, provided with at least two separate cylindrical seats concentric with one another for mounting said sealing elements thereon, said further support elements beng further provided with respective cylindrical rim portions facing towards the respective bearings and adapted to cooperate with said bearings for preventing axial displacement thereof.
- a washing tub 1 of a conventional laundry washing machine of the top-loading type containing a rotatable drum 2 provided with laterally projecting journals 3 and 4.
- Each journal 3, 4 has a cylindrical portion 5, 6 adapted to be received in a respective bearing 7,8 8 supported in tub 1, and a conical portion 9, 10 for connection to a respective circular support 11, 12 secured to the respective lateral wall 13, 14 of drum 2.
- Bearings 7, 8 are carried in further circular supports 15, 16 formed with recessed portions 17 and 18, respectively, constituting seats for said bearings, and planar portions 19 and 20, respectively, adapted to the releasably secured to corresponding circular mounting plates 21, 22 secured to the respective lateral walls 23, 24 of the tub.
- each support element is formed with two separate seats concentric with one another for mounting a pair of annular seals 27, 28 and 29, 30, respectively.
- the support elements are further formed with respective cylindrical rim portions 31, 32 dimensioned to fit into the seats of bearings 7, 8 and projecting thereinto into engagement with the respective bearing.
- Cylindrical rim portions 31 and 32 thus form a stop for the respective bearing 7 and 8, respectively, to prevent axial displacement thereof during rotation of the drum.
- Drum 2 is mounted in tub 1 by initially introducing journal 3 together with bearing 7 into support 15 and positioning support element 25 with its two seals 27 and 28, so that cylindrical rim portion 31 of the support element partially projects into recessed portion 17 of support 15.
- support 15 is secured to the respective circular mounting plate 21 of tub 1 by means of a series of bolts 33, and journal 3 is secured to circular support 11 of drum 2 by means of a threaded bolt 34 penetrating corresponding holes in lateral wall 13 of drum 2 and support 11 and threaded into a threaded bore 35 of journal 3, so that a head 36 of bolt 34 is tightened onto support 11 with a sealing disk 37 of a suitable material interposed therebetween.
- a resilient locking ring 38 of conventional type is secured to the free end thereof.
- annular seals 27 and 28 are retained under axial compression against the outwards curled rim 39 of lateral tub wall 23, and under radial compression, respectively, against drum support 11, by the action of an annular spring 40 seated in a corresponding groove of seal 28, so as to ensure hermetic sealing of the tub.
- support element 25 is securely retained in position, with its cylindrical rim portion 31 engaging bearing 7 so as to prevent axial displacement thereof.
- journal 4 together with bearing 8 is introduced into circular support 16, and support element 26 together with seals 29 and 30 is positioned in the same manner as described above.
- journal 4 is formed with an extension 41 for mounting a pulley 42 thereon.
- Pulley 42 cooperates with a V-belt driven by the motor of the machine, both of which are not shown in the drawing.
- Circular support 16 is secured to mounting plate 22 of tub 1 by means of a series of bolts 43, while journal 4- and pulley 42 are secured to circular drum support 12 by means of a threaded bolt 44 engaging a threaded bore 45 of journal 4, so that a head 46 of the bolt is tightened down onto the outer face of pulley 42. In this manner a hub portion 47 of pulley 42 is biased into engagement with bearing 8, so as to prevent any axial displacement thereof.
- journal 4 is advantageously welded to support 12 of the drum.
- mounting support 16, journal 4 and pulley 42 in the manner described ensures the correct positioning of support element 26 and the compression of seals 29 and 30 against a rim 48 of the tub and support 12 of the drum respectively, with the aid of an annular retaining spring 49.
- journals 3 and 4 In the first place, as journals 3 and 4 no longer come into contact with the laundering liquid as in the case of conventional laundry washing machines, they may be made of less expensive metallic materials which may be non-corrosion-resistant, with the resultant savings of more expensive corrosion-resistant materials.
- all of the employed supports may be formed of sheet metal the processing of which is less complicated than that of the materials employed in present machines.
- the employ of the above described support elements permits the seals for sealing the tub to be correctly positioned and results in a compact drum mounting structure, permitting the drum itself to be housed in a laundry washing machine having reduced dimensions.
- the described drum is readily accessible from the exterior of the drum for repair, maintenance or replacement of the above described drum mounting elements, due to the fact that the supports 15 and 16 giving access to these mounting elements may be released from the respective lateral walls 23 and 24 of the tub from the exterior thereof, resulting in the described solution being highly satisfactory in practical use.
