A Practical Electromagnetic Power-off Brake
Release time:
2021-09-24
Electromagnetic power failure brake is a kind of friction brake with power-on separation (release) and power-off spring brake. It is widely used in metallurgy, construction, chemical industry, food, machine tools, printing, packaging and other machinery, as well as braking during power failure. This brake has the advantages of compact structure, convenient installation, wide adaptability, low noise, high working frequency, sensitive action, and reliable braking. However, when the existing electromagnetic brake is braked, the brake pads come into contact with the exposed rotor to achieve braking. However, the rotor rotates at a high speed together with the device to be braked. When the brake pad is in contact with the exposed rotor, it is easy to generate sparks and cause a fire.
Electromagnetic power failure brake is a kind of friction brake with power-on separation (release) and power-off spring brake. It is widely used in metallurgy, construction, chemical industry, food, machine tools, printing, packaging and other machinery, as well as braking during power failure. This brake has the advantages of compact structure, convenient installation, wide adaptability, low noise, high working frequency, sensitive action, and reliable braking. However, when the existing electromagnetic brake is braked, the brake pads come into contact with the exposed rotor to achieve braking. However, the rotor rotates at a high speed together with the device to be braked. When the brake pad is in contact with the exposed rotor, it is easy to generate sparks and cause a fire.
For this reason, the technical personnel provide an electromagnetic power-off brake to solve the problem that the original rotating part is exposed in the above background art, which is easy to generate sparks and cause fire. In order to achieve the above object, the electromagnetic power-off brake adopts the following technical scheme: an electromagnetic power-off brake includes a support block, two support blocks are provided on the top of the support block, a groove is provided on the top of the two support blocks, and the inner wall of the bottom of the groove is symmetrically provided with four mounting grooves distributed in an annular shape, an electromagnet is fixedly installed in the mounting groove, and a spring fixedly installed on the inner wall of the bottom of the electromagnet is installed groove. The top of the four springs is fixed with the same annular armature, the bottom of the annular armature is in contact with the top of the electromagnet, and the annular armature is located in a groove; the top of the annular armature is fixed with an annular brake disc, and the annular brake disc is located in a groove Inside and slidably connected with the inner wall of a groove; the bottom of the second support block is provided with two grooves, and the annular turntable is rotatably installed in the two grooves, the inner ring of the annular turntable is provided with a plurality of slots with openings at the top and the bottom, and the inner walls of the first groove and the second groove are provided with through holes at the sides away from each other. The outer ring of the annular turntable is fixedly sleeved with a bearing, and the outer ring of the bearing is fixedly connected with the inner wall of the two grooves. The number of chutes is six to ten, and six to ten chutes are annularly distributed. A sphere is nested on the side of the slider away from the annular brake disc, and the sphere is in contact with the inner wall of the corresponding chute. The number of card slots is fifteen to twenty, and fifteen to twenty card slots are annularly distributed. The first support block and the second support block are jointly provided with eight fixing bolts, and the eight fixing bolts are annularly distributed.
Compared with the prior art, the above-mentioned electromagnetic power-off brake has the following beneficial effects: the electromagnetic power-off brake consists of a support block, two support blocks, a groove, a mounting groove, an electromagnet, a spring, an annular armature, and an annular brake. The disc, the sliding groove, the sliding block, the two grooves, the annular turntable, the card groove and the through hole are matched. When the electromagnet is de-energized, the magnetism of the electromagnet disappears, the spring pushes the ring armature to move, and the ring armature pushes the ring brake disc to move. By bringing the annular brake disc into contact with the annular rotating disc rotating at high speed, the shaft to be braked can be braked. Since the annular brake disc and the annular rotary disc are in a relatively closed space, it is possible to prevent sparks from flying, thereby preventing the flying sparks from causing a fire. The electromagnetic power-loss brake has good practicability, can brake the braked shaft quickly, and can prevent fire caused by spark splash.
