Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to an electromagnetic braking ware's technical field, especially a take self-lock device's electromagnetic braking ware's technical field.
[ background of the invention ]
The working principle of the electromagnetic 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 on the friction disc, and friction resistance is formed on the friction disc, so that the friction disc is braked, and equipment connected to the friction disc is braked; when the coil is electrified, the magnetic force generated by the magnetic yoke is opposite to the thrust force generated by the spring, and the armature is attracted to one side of the magnetic yoke by the electromagnetic force larger than the thrust force of the spring to separate the armature from the friction disc, so that a gap is generated between the armature and the friction disc, the friction resistance acting on the friction disc disappears, and the brake is released. Because the electromagnetic brake needs to be always electrified in a non-braking state, the long-term electrification has the following defects: 1. the aging of the components can be accelerated by increasing the temperature of the components, so that the service life is shortened, and the maintenance cost is increased; 2. the power consumption is increased; 3. friction discs in the brake, rubber and plastic parts for reducing noise and the like can expand under the action of high temperature, so that an armature is easy to be incapable of being completely separated from the friction discs, and normal operation is affected.
[ Utility model ] content
The utility model aims at solving the problem among the prior art, providing a take self-lock device's electromagnetic braking ware, can prolong working life, reduce the maintenance cost, reduce power consumption, do not influence normal work.

Preferably, the number of the self-locking devices is two, and the self-locking devices are respectively positioned at the upper end and the lower end of the electromagnetic brake main body.
Preferably, the driving mechanism is an electromagnet.
Preferably, a spring body is provided between the drive mechanism and the lock body.
Preferably, the driving mechanism is fixedly connected with the magnetic yoke through a plurality of fastening bolts, bushings are arranged on the fastening bolts between the driving mechanism and the magnetic yoke, and the locking body is sleeved on the bushings.
