Definitions

  • the present invention relates to a laundering machine.
  • the present invention relates to a laundering machine of the type comprising a casing; a drum fitted to the casing to rotate about a first fixed axis; and drum actuating means comprising a motor having an output shaft, and a belt drive having a belt looped about the output shaft of the motor and the drum to connect the drum angularly to the output shaft.
  • the belt is looped about the drum, and about a pulley fitted to the motor, eccentrically with respect to the motor output shaft axis, and connected angularly to the output shaft by a friction wheel.
  • the motor is mounted for rotation, by means of bearings, on a support integral with the casing, and is rotated, together with the pulley, about the output shaft axis by a spring, which is stretched between the motor housing and the casing, and exerts a twisting moment to preload the motor housing.
  • a laundering machine as claimed in Claim 1 and, preferably, in any one of the Claims depending directly or indirectly on Claim 1.
  • Number 1 in Figure 1 indicates as a whole a laundering machine - in the example shown, a drier - comprising a casing 2; and a perforated laundry drum 3 fitted to casing 2 and rotated about a fixed axis 4 by an actuating device 5.
  • Actuating device 5 forms part of machine 1, and in turn comprises a motor 6 having a housing 7 fitted to casing 2 by elastic vibration-damping supports 10, and an output shaft 8 rotating (anticlockwise in Figure 1 ) about an axis 9 parallel to axis 4.
  • Actuating device 5 also comprises a belt drive 11 in turn comprising a pulley 12 fitted to output shaft 8, and a belt 13 looped about pulley 12 and drum 3 to connect drum 3 angularly to output shaft 8.
  • Machine 1 also comprises a tensioning device 14 for elastically and automatically compensating for variations in the length of belt 13, to keep belt 13 taut and ensure effective transmission of rotation between output shaft 8 and drum 3.
  • Tensioning device 14 comprises a pulley 15 which is fitted idly to a pin 16 connected rigidly to casing 2 and having a fixed axis 17 parallel to axis 9, and is pressed against the outer surface of the driven branch of belt 13, which winds partly about pulley 15 and rotates pulley 15 about axis 17 in the opposite direction to the rotation direction of output shaft 8.
  • pulley 15 comprises a tubular hub coaxial with axis 17 and defined by a bushing 18 fitted in rotary manner to pin 16, and by a body 19 made of rigid plastic material and fixed integrally to bushing 18, coaxially with axis 17.
  • Pulley 15 also comprises an outer ring 20, also made of rigid plastic material, and which has a contoured peripheral surface defining a seat 21 for belt 13.
  • Pulley 15 also comprises, between body 19 and ring 20, an annular member 22 made of radially elastically deformable material, and which, in use, provides for keeping belt 13 at a constant tension substantially equal to the as-assembled tension of belt 13.
  • pulley 15 is fitted to casing 2 in a position in which, as shown in Figure 1 , the pressure exerted by belt 13 on ring 20 deforms annular member 22, by compressing the portion of annular member 22 facing belt 13, thus moving ring 20 into an eccentric position with respect to axis 17.
  • the elastic reaction of annular member 22 is such as to elastically preload belt 13 sufficiently to keep belt 13 taut, immediately compensate for any stretch of belt 13, and so eliminate the need for periodic manual tensioning of belt 13.
  • annular member 22 is defined by a tubular body made of layers of elastomeric material, and having a cylindrical inner surface connected integrally to body 19, and a cylindrical outer surface connected integrally to ring 20.
  • annular member 22 is defined by a compact layer of elastomeric material, which is connected integrally on the inside to body 19 and on the outside to ring 20, and has a built-in metal, preferably steel, ring 23.
  • annular member 22 may be made of any elastically deformable material.
  • pulley 15 is located inside the space defined by belt 13, and presses against the inner side of belt 13.
