Definitions

  • This patent application relates to tubular motor reducer for the handling of winding roller shutters or sunblinds comprising a mechanic device incorporated in the epicyclic reduction gear used to prevent motion reversibility.
  • the device allows the motor reducer to drag the winding element into rotation in both directions and prevents it from moving backwards and dragging the motor shaft into rotation.
  • the tubular motor reducer comprises a multi-step epicyclic reduction gear housed in a fixed tubular element whose internal wall features a crown gear on which the crown wheels of the various steps of the epicyclic reduction gear engage.
  • the epicyclic reduction gear is dragged into rotation by an electric motor located outside the tubular element and positioned so that its shaft is coaxially aligned with the tubular element, from whose front end the pin for the power takeoff projects.
  • the adapter designed to drag the winding shaft of the roller shutter or sunblind into rotation is splined on the pin.
  • this type of tubular motor reducers is always provided with a safety braking system, used to permanently maintain the winding element in upraised position, thus avoiding the risk of accidentally starting the unwanted dangerous down travel of the winding element in an uncontrolled way because of its own weight.
  • the most frequently used stop device consists in electromagnetic brakes or, altematively, mechanical brakes.
  • the mechanical brakes have the advantage of saving the electric power necessary to activate the electromagnetic brakes and having overheating temperatures lower than the temperatures normally reached by electromagnetic brakes in case of prolonged use.
  • tubular motor reducers for roller shutters or sunblinds feature mechanical devices to make the motion transmission from the electric motor to the power takeoff pin irreversible, so that the power takeoff pin can only be dragged into rotation by the motor reducer, but not by the winding element, whose weight actually generates a twisting moment that discharges on the power takeoff pin.
  • the motion irreversibility devices comprise a pair of disks placed side by side that feature two opposed pairs of front teeth that are mutually fixed and engaged so that the first disk can drag the second one with the same transmission mode as in front coupling joints.
  • the first disk - that is the disk directly dragged into rotation by the electric motor - is splined at the end of the motor shaft that goes through a cylindrical collar on which a cylindrical elicoidal spring is extemally inserted, whose ends are radially bent out and engage from opposed direction one of the front teeth located on the first disk.
  • the spring represents no obstacle to the rotation of the first disk.
  • the spring prevents the motion to be transmitted from the second to the first disk, since the opposed pair of front teeth of the second disk engages with the two bent ends of the spring from the outside. In this way the thrust caused by both teeth on the bent end of the spring determines a stress on the spring itself that tends to tighten the spring tums, thus stopping the spring around the centering collar and block of the second disk.
  • the purpose of the present invention is to eliminate both these inconveniences that are typical of a tubular motor reducer for the handling of winding roller shutters and sunblinds.
  • the tubular motor reducer comprises an electric motor (1) able to rotate both clock and counterclockwise located in extemal coaxial position with respect to a sleeve (2) from which the pin (2a) for the power takeoff of the winding shaft of the roller shutter or sunblind projects.
  • the motion transmission from the motor (1) to the power takeoff pin (2a) occurs through an epicyclic reduction gear made up of three successive steps (3a, 3b and 3c) partly housed inside the sleeve (2), whose internal surface features a crown gear (2b) that engages with the crown wheels of the epicyclic reduction gear.
  • the tubular motor reducer also includes an irreversibility mechanical device made up of a first disk (4) provided with an opposed pair of front teeth (4a), a second disk (5) also provided with an opposed pair of front teeth (5a) and a cylindrical helical spring (6) whose ends (6a) are drawn closer and radially bent out.
  • the two disks (4 and 5) are placed side by side so that the teeth of one disk engage with the teeth of the other disk, with the same type of matching as in front coupling joints.
  • the two engaged pairs of front teeth contain the spring (6) between whose bent ends (6a) one of the teeth (4a) of the first disk (4) is located, while the two teeth (5a) of the second disk (5) are located outside and on opposite sides with respect to the two bent ends (6a) of the spring (6).
  • the tubular motor reducer according to the present invention is characterized by the fact that the pair of disks (4 and 5) with the spring (6) is incorporated into the epicyclic reduction gear and more exactly inserted after the first reduction step (3a).
  • the tubular motor reducer according to the present invention includes a secondary sleeve (7) used to contain the first step (3a) of the epicyclic reduction gear that engages on the opening of the sleeve (2) inside which both the two disks (4 and 5) with spring (6) and the second and third step of the reduction gear are housed.
  • the internal wall of the secondary sleeve (7) also features a crown gear (7a) with which the crown wheels of the first step (3a) engage, while the front of the sleeve (7) features the centering collar (7b) of the spring (6).
  • the first disk (4) is splined at the end of the shaft (8) coming out of the first step (3a), with the shaft that goes through and comes out of the collar (7b).
  • the second disk (5) features a central pinion (5b) that is used to transmit the motion to the crown wheels of the second step (3b).
  • the second disk (5) features a central centering hole on the shaft (8) and is in neutral with respect to the shaft, since the transmission from the shaft (8) to the disk (5) occurs through the disk (4), whose front teeth (4a) drag the front teeth (5a) of the disk (5) into rotation by means of the bent ends (6a) of the spring (6), located between the teeth (4a and 5a) and on which the teeth (4a) directly discharge their thrust.
  • the extemal surface of the collar (7b) features some axial grooves (7c) used to contain the necessary quantity of grease to guarantee a continuous effective lubrication of the sliding surface of the spring (6) that - as mentioned before - rotates around the collar (7b).
  • the continuous automatic lubrication contributes to an even higher noise reduction in the operation of the motor reducer according to the present invention.
