Embodiment Construction

[0016] This kind of double-push electromagnet shown in Fig. 1, its housing 1 is cylindrical, and the middle part is the connector 4 that plays connection and magnetic isolation effect, and the two ends of the housing are sealed with end caps 2, on the housing 1 An electromagnetic coil 6 and a moving iron core are housed in the inner cavity, and the release handle 5 is threaded through the connecting body 4 . The core body 3a of the moving iron core is supported in the inner cavity of the housing, and the core shaft 3b of the moving iron core is supported in the core hole on the end cover 2 of the housing. Wherein, the sliding support contact surface between the core body of the moving iron core and the inner cavity of the housing and the sliding support contact surface between the mandrel shaft and the core hole of the end cover respectively constitute the moving core support friction pair in the double-push electromagnet.

[0017] The double-push electromagnet shown in Figure...

Abstract

The invention relates to an armature translational motion non-oil lubrication double push electro-magnet, its structure is that has two magnet coils and two move iron core in the tube shape shell, the core of move iron core support in the shell cavity, the core axis of move iron core support in the shell or on the shell endcover core hole, the ceramics spurt coating setup on the move core bearing friction of the electro-magnet. This invention primely solved the present elevator move iron core wear well and lubrication question of using brake with double push electro-magnet, under no maintain, non-lubrication operating mode condition, the safe operation times might reach 1000-15 million; can definitely meet the elevator safe operation needs in main engine service life period. It is a new elecetromagnet of using elevator brake with no open solution, no maintenance, no lubrication.

Description

technical field [0001] The invention relates to an electromagnet whose armature can move linearly, in particular to an oil-free lubricated double-push electromagnet. Background technique [0002] At present, double-push electromagnets have been widely used in elevator brakes as brake release devices. The structure of the double-push electromagnet is that two electromagnetic coils and two moving iron cores (armatures) are installed in the cylindrical shell (yoke iron), the core body of the moving iron core is supported in the inner cavity of the shell, and the The mandrel is supported in a core hole in the housing or housing end cap. When the electromagnet is energized, a closed magnetic field is generated between the electromagnetic coil, the moving iron core and the housing, and the moving iron core in the magnetic conduction circuit, under the action of the magnetic field, overcomes the elastic force of the brake spring to generate a magnetic field outward. Displacement,...
