Description
Technical field
The utility model relates to a kind of low-noise brake, particularly a kind of low-noise brake for towing machine.
Background technology
At present, along with the development of national economy and the raising of people's living standard, modern high-rise building spreads all over town and country.For guarantee in the skyscraper flow of personnel rapidly, safety, satisfy the allegro needs of the modern life, improve the in-use performance of operating efficiency and equipment, require also more and more higher to the Design and manufacture of elevator.And the deceleration and stopping performance of towing machine directly has influence on the safety and effectiveness of elevator.And present most magnet stoppers that are used for the towing machine braking all are by the iron core adhesive or discharge armature and make its action, and armature moment of release compresses brake disc to brake.But the moment when discharging owing to armature, impulsive force is very large, can produce the larger bump sound during impact, so noise is larger.
The utility model content
The purpose of this utility model is, the low-noise brake that provides a kind of towing machine to use.The impact noise that it produces in the time of can reducing the drg braking.
The technical solution of the utility model: the low-noise brake that a kind of towing machine is used, be characterized in: comprise the iron core that coil is installed, iron core is provided with mounting screw, mounting screw passes successively behind iron core and the armature and end cap is installed is linked to each other, armature and install and clamping between the end cap brake disc to be arranged, disc centres is the tubular axis with spline, and links to each other with installation shaft by the spline housing on the installation shaft; Described armature is provided with elastomeric shock structure, and the distributing position of shock structure on armature is in the outer ring of corresponding brake disc position.
In the low-noise brake that aforesaid towing machine is used, described armature is provided with elastic cylindrical pin, and shock structure is set on the elastic cylindrical pin and (offers the straight pin of notch such as the centre).
In the low-noise brake that aforesaid towing machine is used, cover has the hollow bolt on the described mounting screw, and the hollow bolt is behind the armature and between the installation end cap; Described armature comprises two the right armature and the left armature that are merged into a complete circle; Be provided with cushion blocking between armature and the iron core, the position of cushion blocking is positioned at the junction of right armature and left armature.
In the low-noise brake that aforesaid towing machine is used, described brake disc links to each other with the installation shaft end with regulating spring by set screw, distance with set screw adjustable brake dish and end cap, thereby the gap of adjustable brake dish and end cap, and regulating spring provides buffering when brake disc is subject to the compression shock of armature, further reduce impact noise.
In the low-noise brake that aforesaid towing machine is used, described iron core middle part is provided with circular groove, is provided with the coil of annular in the circular groove, and the coil middle part is provided with magnetic conduction iron, coil and magnetic conduction iron and circular groove shape complementarity.
Compared with prior art, the utility model arranges shock structure by the armature at magnet stopper, when armature pressed to brake disc, the shock structure on the armature at first collided with end cap is installed, and has reduced armature and has directly clashed into bump impact noise 6～10dB that brake disc produces.Be easy to regard to compressed deformation after having elastomeric shock structure pressurized, therefore reduce also very littlely to the pressure of brake disc, can not affect braking effect.And because armature and end cap is installed is can not be in relative rotation, so shock structure only can be subject to axial pressure, and can frictional loss, required buffering when the column structure of shock structure can effectively be realized braking.Set screw be arranged so that the distance of brake disc and end cap is adjustable when normal operation, provide axial force in advance to brake disc, so that brake disc does not need fully by centnifugal force and friction force and the disengaging of installation end cap, so that brake disc and installation end cap grating and the frictional loss when not exclusively breaking away from directly will be 0, comfort level and the safety of running have greatly been improved, also improve the life-span of friction lining, reduced the frictional loss of friction lining.In addition, the installation of coil normally is embedded in coil at the circular groove of iron core on the existing drg, carries out the encapsulating encapsulation, and installation difficulty is larger, needs the workman to embed by hand, waste time and energy, and it is high to add grooving in man-hour cost; And coil of the present utility model to install be coil directly to be wound on form the iron core winding on the skeleton, again with the iron core winding with the iron core base assembling, compare so existing encapsulating encapsulation saving the cost more than 10%, tooling cost is also saved more than 5%.And the coiling of coil and skeleton can be tightr, improved electromagnetic attraction, and iron core base and skeleton processing are simple, have improved work efficiency and have reduced cost.
