Embodiment Construction

[0016] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0017] Such as Figure 1 to Figure 5 As shown, the de-energized brake includes a yoke 1 with a built-in coil slot 14, an excitation coil 3 is arranged in the coil slot 14, an armature 4 is placed on the inner end surface of the yoke 1, and a cover plate is connected to one end of the yoke 1 6. An intermediate body 10 connecting the transmission block 7 is provided between the cover plate 6 and the armature 4. The intermediate body 10 is made of iron, and the inner wall of the intermediate body 10 is closely matched with the transmission block 7. The intermediate body 10 Friction bodies 5 are provided at both ends, and the outer diameter of the friction body 5 is the same as that of the intermediate body 10. The inner end surface of the yoke 1 is provided with a plurality of spring seats 13 and spring p...

Abstract

The invention discloses a de-energized brake, which comprises a magnetic yoke with a built-in coil slot, an excitation coil is arranged in the coil slot, an armature placed on the inner end surface of the magnetic yoke, a cover plate is connected to one end of the magnetic yoke, and the cover An intermediate body connecting the transmission block is provided between the plate and the armature, friction bodies are provided at both ends of the intermediate body, multiple spring seats and spring pin seats are provided on the inner end surface of the yoke, and springs are installed in the spring seat. , a spring pin is installed in the spring pin seat, and one end of the spring pin is fixed on the spring pin seat. The de-energized brake of the invention has the advantages of small volume, reasonable layout, good braking performance and strong environmental adaptability.

Description

technical field [0001] The invention relates to a power-off brake, which belongs to the technical field of brake manufacture. Background technique [0002] Existing brakes are mainly composed of a brake frame, brake parts, and a control device. By controlling the control device, the brake parts move to generate friction, thereby realizing braking. Because the existing brake is braked by the moment of friction generated by mechanical movement, the volume of the brake frame and the brake parts is large, and the heat generated during the braking process is relatively large. Contents of the invention [0003] The purpose of the present invention is to provide a de-energized brake with reasonable design, small volume, good braking performance and strong heat dissipation. [0004] The technical solution of the present invention is: a de-energized brake, including a magnetic yoke with a built-in coil slot, an excitation coil is arranged in the coil slot, and an armature placed o...
