Problems solved by technology
However, since the brake disc cannot be moved, the friction plate always rubs against the end cover during rotation, which not only increases the heat generation of the worn friction plate, but also increases the resistance torque of the rotating shaft

Embodiment
[0020] Example: such as figure 1 , figure 2 and image 3 As shown, an electromagnetic brake using air flow separation includes a yoke 1, a coil 2, an armature 4, a brake spring 3, a brake disc 5 and an end cover 6, and the coil 2 is installed in the yoke 1, The armature 4 and the brake disc 5 are arranged between the yoke 1 and the end cover 6, and the brake spring 3 pushes the armature 4 away from the yoke 1, so that the The armature 4 and the end cover 6 press against the brake disc 5 for braking. The brake disc 5 is a split structure, including a brake bushing 51 and a brake disc 52 . The left and right sides of the brake disc 52 are provided with friction plates 53, the friction plates 53 are ring-shaped, and are bonded to the outer circle of the brake disc 52, and the friction plates 53 are in diameter The width in the radial direction is 1 / 2-3 / 4 of the width of the brake disc 52 in the radial direction.
[0021] The brake disc 52 is sleeved on the brake sleeve 51 ,...

The invention relates to the technical field of electromagnetic brakes, in particular to an electromagnetic brake for achieving separation through airflow. The electromagnetic brake comprises a magnet yoke, a coil, an armature, a brake spring, a brake disc and an end cover. The coil is installed in the magnet yoke, the armature and the brake disc are arranged between the magnet yoke and the end cover, the brake spring pushes the armature to enable the armature and the end cover to press the brake disc for braking, the brake disc is of a split structure and comprises a brake shaft sleeve and a brake puck, the left side and the right side of the brake puck are provided with friction pieces, the brake shaft sleeve is sleeved with the brake puck, the brake shaft sleeve and the brake puck are connected through splines and rotate synchronously, and the brake puck moves in the axial direction relative to the brake shaft sleeve. The brake disc is of the split structure, so that the brake disc is far away from the end cover without influencing transmission, and the problem that the friction pieces and the end cover produce friction and then produce heat, and therefore the service life of the friction pieces is shortened is avoided.
Description
technical field [0001] The invention relates to the technical field of electromagnetic brakes, in particular to an electromagnetic brake using airflow separation. Background technique [0002] The existing electromagnetic power-off brake is a friction brake with power-on disengagement and power-off spring braking, which is widely used in metallurgy, construction, chemical industry, machine tools, elevators and other machinery. This kind of brake has the advantages of compact structure, convenient installation, wide adaptability, low noise, high working frequency, sensitive action, reliable braking, etc. It is an ideal automatic actuator. The brake is externally connected with a half-wave rectifier, which converts the unidirectional alternating current into direct current. After electrification, the winding generates a magnetic field to draw the armature back, and at the same time the armature compresses the spring fixed in the iron core. When the power is off, the winding ...
