Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Examples
As shown in fig. 1, an electronic rolling door machine brake coil subassembly, including yoke subassembly and coil pack, yoke subassembly and coil pack fixed connection, and the axial lead collineation setting of yoke subassembly and coil pack, the yoke subassembly includes yoke iron core 3, yoke casing 4 and gasket 5, yoke iron core 3 passes through gasket 5 and 4 fixed connection of yoke casing, and yoke iron core 3, the axial lead collineation setting of yoke casing 4 and gasket 5, the coil pack includes coil 1 and skeleton 2, skeleton 2 is axial hollow frame, 2 middle sections of skeleton are equipped with the ring channel, 1 wire winding of coil is in the ring channel of skeleton 2, coil 1 holds in the ring channel completely, the material and the wire winding number of turns of coil set up according to reality.
An end face of skeleton 2 offsets with 5 terminal surfaces of gasket, and the setting of skeleton 2 is run through to the yoke iron core 3 axial, and yoke iron core 3 and skeleton 2 clearance fit.
Further, yoke subassembly and coil pack link to be integrative through the riveting, and the riveting makes yoke subassembly and coil pack connect better fastening, can not produce easily not hard up, reduces the noise production in the use.
Further, yoke iron core 3, yoke casing 4 and gasket 5 are linked into an organic whole through riveting or welding, adopt fastening connection's mode, prevent to produce between yoke iron core 3, yoke casing 4 and the gasket 5 and remove.
Further, the end face of the magnetic yoke shell 4 is provided with a through hole for the coil to penetrate through.
Further, the yoke iron core 3 is a high-magnetic-flux-rate iron core, and the high-magnetic-flux-rate iron core is favorable for enhancing the electromagnetic adsorption force after power is on.
The direct current braking force of the traditional coil assembly is 200N, the installation gap is 0.3MM, the infirm problem and the 30N braking resistance exist at the same time, the invention can realize the continuous test of the braking force of the installation gap of 0.5MM and 230N for 10 minutes, the braking resistance is less than 10N, and in comparison, the heating value of the assembly can be reduced.
