Definitions

  • the arrangement of the centrifugal clutch between the motor and the speed reducer requires careful operations of axial alignment of the different elements to avoid any premature wear of the pinions of the speed reducer.
  • the mounting of such a device is complicated.
  • the direction of starting of the motor is random depending on the type of electric motor used. It is conventional for synchronous motors to make use of a non-return pawl to impose a predetermined direction of rotation. Known pawls operate by friction effect, and are subject to premature wear.
  • the object of the invention is to provide a geared motor equipped with a centrifugal clutch with quick and simple assembly.
  • the means for driving the bell comprise a friction lining fixed on the internal lateral surface.
  • the outer periphery of the bell is shaped according to a hooking toothing capable of cooperating with locking means following the stopping of the engine.
  • the rotor is provided with stop means intended to cooperate with a pawl to determine the direction of starting of the engine.
  • the stop means comprise at least one tooth disposed axially opposite the insert and the pawl is articulated on an axis being polarized by a spring on said tooth.
  • the metal insert of the rotor of plastic material is extended by a cylindrical rod, having a semi-spherical end bearing on a flat bottom of the hole, in the inserted position of the rotor in the bell.
  • a remote control module 10 for a circuit breaker block comprises an insulating housing 12 enclosing a geared motor assembly 14 serving as a drive member for a lever 15 associated with a transmission link (not shown) to authorize the opening and closing of the circuit breaker.
  • the operation of the transmission link is described in detail in document FR-A-2699733.
  • the geared motor assembly 14 is equipped with an electric motor 16 with alternating current mechanically coupled to a speed reducer by means of a centrifugal clutch 18.
  • the motor 16 comprises a stator 20 with inductor, and a rotary armature 22 equipped an axis 24 for driving the clutch 18.
  • the reciprocating motor 16 is an asynchronous motor with a random start direction, but any other type of motor can be used.
  • the centrifugal clutch 18 comprises a rotor 26 with two weights 28, 30, capable of spreading radially under the effect of the centrifugal force, the rotor 26 being arranged inside a clutch bell 32 in annular shape.
  • the axis 24 of the motor 16 is fitted into an orifice 34 of an insert 36 of the rotor 26, and stop means 38 are located on the side of the orifice 34, and on the face of the rotor 26 located opposite the motor. 16.
  • the clutch 18 is produced by molding a plastic material, the rotor 26 constituting the driving element, and the bell 32 forming the driven element.
  • the internal lateral surface of the annular bell 32 is coated with a friction lining 40, which cooperates with the ends of the two flyweights 28, 30 of the rotor 26 during the rotation of the motor 16.
  • the abutment means 38 of the rotor 26 include a pair of teeth 42, 44 diametrically opposite with respect to the orifice 34, and intended to cooperate with a pawl 46 to determine the direction of starting of the motor 16.
  • the pawl 46 is articulated on a fixed axis 48 (FIGS. 8 to 10) , and is biased by a spring 50 on the teeth 42, 44 of the stop means 38.
  • the clutch bell 32 is provided with an axial protuberance 52 with a blind hole 54 for housing the insert 36 of the rotor 26.
  • a pinion 56 is arranged on the external cylindrical surface of the protuberance 52 to serve as an organ d drive of the speed reducer.
  • the outer periphery of the bell 32 has a hooking toothing 58 capable of cooperating with a locking lever 60 (FIG. 1) pivotally mounted on an axis 62 between a locking position. , and an unlocking position.
  • the locking lever 60 is actuated between the locking and unlocking positions by means of an electromagnet 64, the excitation of which occurs at the end of the closing stroke following the stopping of the motor 16.
  • the metal insert 36 of the plastic rotor 26 is extended by a cylindrical rod 66 having a semi-spherical end 68 constituting a ball, which bears on the flat bottom of the hole 54 in the inserted position of the rotor 26 in the bell 32.
  • the coming into axial engagement of the rod 66 of the insert 36 on the bottom of the hole 54 takes place at a contact point, so as to reduce the frictional forces during the rotation of the rotor 26.
  • a polarization blade 70 ( Figure 1) made of elastic flexible material, is fixed on a stud 72 of the cover of the housing 12, and its opposite end bears on the protuberance 52 of the bell 32 to suppress all the mechanical vibrations that may be generated during the rotation of the centrifugal clutch 18.
  • the clutch bell 32 fulfills a first coupling function when the counterweights 28, 30 come into contact with the friction lining 40, a second support function for the pinion gear 56 of the speed reducer, and a third stop function by the action of the locking lever 60 on the hooking toothing 58 during the excitation of the electromagnet 64.
  • the insert 36 of the rotor 26 serves as a cantilever support for the bell 32 of the clutch and of the guiding member in rotation of the pinion 56.
  • the teeth 42, 44 of the abutment means 38 of the rotor 26 cooperate with the pawl 46 to serve as a unidirectional starting member for the rotary motor 16.
  • FIG. 8 represents the centrifugal clutch in the inactive position during the stopping of the engine 16.
  • the counterweights 28, 30 remain stationary and separated from the friction lining 40 by a radial clearance.
  • the pawl 46 is supported on one of the teeth 42, 44 by the action of the associated spring 50.
  • the motor 16 when powered, has a random start direction.
  • the teeth 42, 44 of the abutment means 38 push the pawl 46 against the elastic force of the spring 50, allowing the rotation of the rotor 26 , and the radial spacing of the counterweights 28, 30 against the lining 40 under the effect of centrifugal force.
  • the clutch bell 32 is then rotated, as is the pinion 56 of the speed reducer.
  • the action of the elastic blade 70 on the protuberance 52 of the bell 32 allows regular rotation of the clutch 26, and eliminates any mechanical vibration.
  • the motor 16 starts in the undesired direction (FIG. 10)
  • one of the teeth 42, 44 of the rotor 26 abuts against the end of the pawl 46. This results in a mechanical shock which instantly stops the rotor 26, and starts the motor 16 in the other direction of rotation.
  • the electromagnet 64 is excited simultaneously with the interruption of the supply to the motor 16, causing the clutch 18 and the speed reducer to stop.
