摘要： In a braking apparatus, a forcing device forces a movable portion in a direction that places a friction member in contact with a rotating body. A braking force releasing device displaces the movable portion in a direction in which the friction member separates from the rotating body in opposition to the forcing device. A buffering member is disposed between a fixed portion and the movable portion, and is made of a flexible material. A deforming device deforms the buffering member by pressing the buffering member in a direction that is perpendicular to the direction of displacement of the movable portion.

摘要： A braking apparatus main body has: a movable body; and an electromagnetic actuator that displaces the movable body in a direction of contact with and separation from a rotating body that is rotated relative to a hoisting machine main body. An adjusting collar is screwed into an adjusting threaded aperture disposed on the electromagnetic actuator. The adjusting collar is disposed between the hoisting machine main body and the electromagnetic actuator. The electromagnetic actuator is mounted to the hoisting machine main body by a mounting device in a state in which the hoisting machine main body bears the adjusting collar. A position of the braking apparatus main body relative to the hoisting machine main body is adjusted in a direction in which a distance between the electromagnetic actuator and the rotating body changes by adjusting an amount of thread engagement of the adjusting collar in the adjusting threaded aperture.

摘要： 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.

摘要： A method for monitoring the operating state of an elevator drive having a brake includes the mounting of a sensor on a movable brake part. The sensor generates an output proportional to the extent of relative movement between the brake part upon which it is mounted and a fixed brake part. The sensor output is monitored to provide an indication of the operating state of the drive and may be combined with other data to provide indications of a variety of drive states.
