[0019] figure 1 It is a front view showing the elevator hoisting machine provided with the direct-acting wheel brake device of the elevator according to the first embodiment of the present invention.

[0020] In the drawing, a main shaft (fixed shaft or rotating shaft) 2 is provided at the center of a casing 1 of an elevator hoisting machine. A cylindrical brake wheel 3 that is rotatable around the main shaft 2 is provided on the main shaft 2 .

[0021] A pair of direct-acting wheel brake devices 4 (hereinafter, simply referred to as brake devices 4) are installed on both sides of the housing 1, and the brake devices 4 control the rotation of the brake wheel 3 as the braked part. brake. These brake devices 4 are arranged so as to sandwich the brake wheels 3 from both sides. That is, the brake device 4 is disposed outside the brake wheel 3 .

[0022] The brake device 4 mainly includes a fixed iron core 5, a movable iron core 6, a brake coil 7, a brake spring 8, a brake shoe...

Abstract

In an elevator direct-acting drum braking apparatus, a brake shoe is mounted to a movable core. A lining that is placed in contact with and separated from a brake drum is disposed on the brake shoe. The brake shoe is slidable relative to the movable core within a predetermined range in a direction that is perpendicular to a direction of contact with and separation from the brake drum and perpendicular to an axial direction of the brake drum. An elastic body that presses and holds the brake shoe against the movable core is disposed on the movable core.

Description

technical field [0001] The present invention relates to a direct-acting wheel brake device of an elevator, which is installed in an elevator traction machine and brakes the rotation of the brake wheel. Background technique [0002] In the existing braking device of the elevator traction machine, the brake shoe and the movable iron core are connected by two parallel connecting parts. The connection members are arranged near both ends of the brake shoe. The base end of each connecting member is fixed to the movable iron core. In addition, the end of each connecting member is attached to the brake shoe via a spherical seat mechanism (for example, refer to Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2002-284486 Contents of the invention [0006] The problem to be solved by the invention [0007] In the above-mentioned conventional brake device, although the eccentricity between the ...
