Description

Combined coil installation module of power-off brake

[ technical field ] A

The utility model relates to a lose electric brake's technical field, especially a lose electric brake's combination formula coil installation module's technical field.

[ background of the invention ]

The power-off brake is a mechanical device for braking and releasing a brake disc by using a spring and a power supply as power sources, and performs braking under the condition of power failure, so the power-off brake is called as the power-off brake. The structure of the magnetic release device comprises a magnetic yoke, an armature, a spring, a coil, a friction disc, a friction plate, a release handle, a microswitch and the like. The working principle of the power-off brake is as follows: the magnet yoke and a coil arranged on the magnet yoke form an electromagnet, when the coil is not electrified, the spring presses the armature iron on the friction plate, and friction resistance is formed on the friction plate, so that the friction plate is braked, and equipment connected to the friction plate is braked; when the coil is electrified, the magnetic force generated by the magnetic yoke is opposite to the thrust generated by the spring, and the armature is attracted to one side of the magnetic yoke by the electromagnetic force larger than the thrust of the spring to separate the armature from the friction plate, so that a gap is generated between the armature and the friction plate, the friction resistance acting on the friction plate disappears, and the brake is released.

In the prior art, as shown in figure 1, an integral-forming type magnetic yoke with a plurality of coil mounting grooves is manufactured by cutting a magnetic yoke plate through cutting processing equipment such as a milling machine and the like, and belongs to a material reduction method.
