Abstract
The invention relates to a dual-thrust magnetic machine of a dual-support structure. The dual-thrust magnetic machine of the dual-support structure comprises a housing, a solenoid coil, two movable iron cores with mandrels at the external ends, two end covers and two front bearings, wherein the mandrels are made of non-magnetic conductivity materials, the solenoid coil is in an annular structure and fixed on the two sides of the housing, the two end covers are respectively fixed at the two ends of the housing, the two front bearings are respectively arranged inside bearing holes of the two end covers, the two movable iron cores are arranged at the two internal ends of the housing in a sliding manner, and the mandrels at the external ends of the two movable iron cores respectively penetrate out of the two front bearings in a sliding manner. The dual-thrust magnetic machine of the dual-support structure is characterized in that a supporting frame is arranged at the middle part inside the housing, shafts are arranged on both of the two end faces of the supporting frame, holes are arranged at the rear ends of the two movable iron cores corresponding to the shafts, rear bearings are arranged inside the holes, and the shafts penetrate inside the bearings in a sliding manner. Compared with the prior art, the dual-thrust magnetic machine of the dual-support structure disclosed by the invention has the following advantages that the magnetic resistance from the movable iron cores to a bracket is low, which is good for increasing the magnetic thrust; and moving parts are supported by the two sliding bearings, so that the friction reduction performance is excellent, and the service life is long, and reliability and safety can be improved.
Description
Technical field
The present invention relates to a kind of double-push magnetic device of brake, refer to especially a kind of dual-support structure double-push magnetic device.
Background technology
The double-push magnetic device structure of existing brake usually as shown in Figure 1, housing 1 middle part is connected to ring support 1b, electrical field coil 4 and moving iron core 3 are housed in housing, the housing two ends are equipped with end cap, on moving iron core 3, an end is connected with mandrel 8, mandrel 8 is supported on the sliding bearing at end cap center, moving iron core 3 rear ends are supported in the core hole of supporter 2, when coil electricity or outage, moving iron core 3 slides in sliding bearing and supporter together with mandrel 8, the supporting surface of moving iron core will wear and tear in moving iron core motion process, supporter also there will be wearing and tearing, make the rubbing surface fluffing, finally cause moving core clamping stagnation.If, after the moving core clamping stagnation of double-push magnetic device occurs in the Xie Zha of elevator brake just, the braking action of brake will be lost efficacy so thereupon, for the man lift, its consequence is very serious, tends to jeopardize passenger's life security.This just requires the professional regularly elevator brake is safeguarded, maintained and lubricates, and still, along with the surge of elevator usage quantity, the maintenance work of elevator is increasing.Therefore, the wear-resisting and lubrication problem of the moving iron core of double-push magnetic device, become large difficult point and the focus in elevator brake manufacturing field.
Summary of the invention
The objective of the invention is: a kind of double-push magnetic device of dual-support structure is provided, to solve wearing and tearing and the clamping stagnation problem in moving iron core running, to reduce and to safeguard, improves security reliability.
The object of the present invention is achieved like this: comprise housing, solenoid, two outboard end are with the moving iron core of mandrel, two end cap, two fore bearings, the material of mandrel is non-magnet material, solenoid is loop configuration the both sides that are fixed on housing, two end cap is separately fixed at the two ends of housing, two fore bearings are separately positioned in the dead eye of two end cap, two moving iron cores are slidably arranged in respectively two ends in housing, the mandrel of the outboard end of two moving iron cores slides respectively and passes outside two fore bearings, its special feature is that middle part is provided with bracing frame in housing, be provided with axle on the bracing frame both ends of the surface, two moving iron core rear ends of respective shaft arrange porose, be provided with rear bearing in hole, axle slides and pierces in bearing.
For convenient for assembly, housing comprises tubular overcoat, annular support, and ring support is positioned at the middle part of tubular overcoat endoporus, and two solenoids lay respectively at the two ends of annular support, and bracing frame is arranged on the middle part in annular support.
Aspect electromagnetism, during coil electricity, the magnetic flux of the moving iron core rear end of flowing through divides two parts, a part is through moving iron core rear end → air-gap → annular support, and another magnetic flux is through moving iron core hole → air-gap → bracing frame axle → annular support, like this, can guarantee that magnetic resistance reduces a lot, to be conducive to increase magnetic thrust; In mechanical aspects, when moving iron core slides on fore bearing together with mandrel, in the affixed moving iron core of rear bearing hole, when moving, moving iron core can on the axle at bracing frame center, slide together with rear bearing, and be equivalent to moving iron core and support by two sliding bearings.
Compared with the prior art, its beneficial effect is in the present invention:
1 moving iron core is little to the magnetic resistance of support, is conducive to increase magnetic thrust;
2 moving components adopt two sliding bearings to support, and antifriction quality is good, and the life-span is long, has improved reliability and fail safe.
