  • Publication number: 20090194370
    Abstract: A brake assembly (18) includes a permanent magnet (36) that generates a first magnetic field (52) in a direction that causes application of a clamping force on a brake disk (22). An electromagnet (38) is energized with current of a proper polarity to generate a second magnetic field (54) opposite the first magnetic field (52). The rate and magnitude at which current is applied produces a controlled repulsive force between the two magnetic fields (52, 54) to disengage the brake disk (22). As a distance between the permanent magnet (36) and the electromagnet (38) increases, the difference in field strength decreases until an equilibrium position is obtained. The brake is applied and released in a controlled manner by varying the strength of the second magnetic field (54) relative to the first magnetic field generated by the (36).

    Abstract: An elevator drive with a brake device has compression springs that act on brake levers, whereby brake linings generate a brake force on a brake drum. The more the brake linings wear due to abrasion, the smaller the distance of the plunger from the brake magnet housing becomes. Should the plunger come into contact with the brake magnet housing, the braking capacity of the brake linings is completely eliminated creating an operating condition that is dangerous for elevator users. A switch is provided that detects a minimum distance. The switch can be arranged on the plunger of the brake magnet and detect the minimum distance to the brake magnet housing or, in the case of a retrofit, the switch can be arranged on the brake magnet rod and, for example, detect the distance of the second joint from the brake magnet housing, and at the minimum distance the switch switches.

The holding force is determined substantially by the biasing force acting on the mount.

  • Patent number: 7364019
    Abstract: The present invention is about a traction sheave elevator, without the machine room, comprising an elevator car that runs on guide rails placed in the shaft and connected to at least one hoisting rope un-coiling on a diverting pulley driven by a traction sheave. The invention's characteristic consists in comprising a space, outside the elevator shaft, which houses, at least partially, the traction sheave and is equipped with an opening near a floor's door for the access to the drive machine and to the traction sheave, from outside the shaft. The invention also provides for arranging the two diverting pulleys on the counterweight and on the elevator car in a way that one or the other can be tilted with respect to the vertical or arranging them on the same axis and on the same body of the pulley with the grooves of the alternating hoisting ropes.

  • Publication number: 20080053755
    Abstract: A guide device for an elevator car has a guide shoe that is displaceable by a linear guide that is arranged on the elevator car. Should the elevator car in an extreme situation travel beyond the uppermost floor, the guide shoe is arrested by a projecting console, and the elevator car travels past the console. The linear guide permits the guide shoe to execute a movement relative to the elevator car. Thus, the elevator car, or parts thereof, utilizes the hoistway headroom that is provided for the drive unit or other hoistway equipment. The counterweight can be provided with the displaceable guide shoe for utilizing the hoistway pit in a similar manner.

  • Patent number: 7296660
    Abstract: An elevator for moving a person between two levels. The system includes at least one carriage in a hoist way extending between two floors. A lever arm lifting system moves the carriage. The lever arm may be an articulated lever arm having a primary arm having a first end rotating on a primary shaft supported on the building structure and a primary sprocket wheel fixed to the primary shaft. A secondary arm has a first end rotating on a secondary shaft carried on a second end of the primary arm. A secondary sprocket wheel is also carried on the secondary shaft and is fixed to the secondary arm. The primary and secondary sprocket wheels are coupled by a chain belt. A second end of the secondary arm is coupled to the carriage. An electric motor is coupled to the primary arm to rotate it around the primary shaft, and to thereby move the carriage between the two levels.

  • Patent number: 7293631
    Abstract: There is provided an machineroom-less elevator which can reduce the pit depth in a bottom part of an elevator shaft, mostly perform maintenance work on an upper space of a cage, and reduce a top clearance. A pair of right and left cage-side sheaves are disposed in the upper space of the cage, and the rotational axes of the traction sheave and the cage-side sheaves are extended in the longitudinal direction. A sheave supporting beam to rotatably support cage-side sheaves is disposed in a space between and upper beam of the cage frame and a ceiling of the cage, and disposed below rotary shafts of the cage-side sheaves.

  • Patent number: 7243759
    Abstract: There is disclosed a coupling arrangement for coupling a motor to a hoist machine. The coupling arrangement comprises a first drum flange comprising an outer body having a first end and a second end, and an inner wall surface defining a cavity of substantially circular cross section. The cavity has a given diameter along a first length of the body, and of reducing diameter along a second length of the body. The flange is adapted to receive at the first end a tapered bushing of increasing diameter and dimensioned such that, upon insertion of the bushing within the body a given length, the bushing frictionally engages with the inner wall surface of reducing diameter for retention therein. The bushing has a central cavity for receiving the shaft of the motor and capable of securing onto the shaft.
