Embodiment Construction

[0033] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0034] figure 1 is a top view showing the overall outline of a brake for a winch gearbox such as a hoist or hoist. Reference numeral 1 designates an electric motor, reference numeral 2 designates a drum (cable drum), and reference numeral 3 designates a brake. The output of the motor 1 makes the reel 2 rotate through a coupling 4, a reduction gear 5, and a coupling 6.

[0035] figure 2 Yes figure 1 In an enlarged view of the schematic part shown, the shaft 7 of the reel 2 is rotatably supported by a pair of bearings 8, 9, and the reel 2 is free to rotate. The first bearing 8 supports a figure 1 The input shaft portion 7a of the coupling 6 is shown, and the second bearing 9 supports a protruding shaft portion 7b.

Abstract

A brake for a hoist gear is provided with a pair of brake shoes for braking a disk to be braked arranged on a winding drum side by pressing both sides of the disk. Floating pin fitting piece portions protrude integrally from a body of a bearing supporting the winding drum. A caliper is attached to the fitting piece portions through floating pins. Axis points of the floating pins are arranged in point symmetry of approximately 180 DEG in respect of an axis point of a push rod inserted into the caliper in order to uniformly contact the disk face.

Description

technical field [0001] The invention relates to a brake for a winch gearbox. Background technique [0002] A conventional brake for a winch gearbox (for example, a hoist) includes a drum for winding a wire rope and a bearing for supporting the drum as one unit and a brake located separately from the unit. [0003] The combination of the main part of the winch gearbox and the brake has a complex structure, and it is relatively difficult to reduce the space required for the brake. Due to the conditions when using a winch gearbox (e.g. a winch), it is not possible to adjust the discs and brake shoes of the brake to each other by actually using the brake for the winch gearbox, so it is difficult in some cases The brake shoes will be positioned for even contact with the disc face. Contents of the invention [0004] It is therefore an object of the present invention to provide a brake for a winch gearbox in which the foregoing problems are solved and the brake shoe can be adju...
