Abstract
The utility model discloses an electromagnetic brake with permanent magnets which adopts permanent magnets and traditional electromagnets together. The electromagnetic brake with the permanent magnets comprises at least one electromagnet main body (1), a movable locating device (4), a series of thrust springs (5) and a brake plate (8), wherein the brake plate (8) is integrally formed with a driving shaft through a connector and/or a feather key in a coupling mode. The electromagnetic brake with the permanent magnet is characterized in that a series of permanent magnets (6) and the electromagnets (6') cooperates to overcome the elastic force of the thrust springs (5).
Description
Technical field
The utility model relates to a kind of modification by the disclosed invention of patent BO2011A000310 (it is with under the name identical with the application's claimant), this patent relates to uses identical basic inventive principle in dissimilar break, and it is called the direct current negative electricity magnetic spring pressure break that is applied to " dynamically ".
Technical background
The concrete electromagnetic brake with reference to " retarder " type of description of the present utility model, it comprises a single braking surface, the feature of this braking surface is that usually it has the material of high coefficient of friction, this braking surface binds or is mold formed on a side of moving positioning device, and the geared brake dish, this brake disks is by molded or outer molded one-body molded with air-cooling fan.The overall dimensions of such break is generally less, and has medium braking moment, therefore is adapted at using in motor or the gear motor reduction unit.When needs break arrestment (for example, woodworking machinery or general cutting machine) or keep on the Whole Equipment for static or slowing down to rise and to use such break when doing to interfere (if under the operation at inverter) after finishing safely.Brake disks-fan comprises by the integrally formed fan of single iron casting and this brake disks or comprises an aluminium fan that is molded on the steel disk outward, this fan provides flywheel effect, this flywheel effect has strengthened the braking of splendid starting process and typical direct current break, and making this brake disks-fan be specially adapted to less translational motion, this less translational motion needs brake operating more for a long time and larger braking energy usually.
Same inventive concept also can be applied to the direct current electromagnetic spring press-brake device of each type apparently, this break be characterised in that have at least one electromagnet main body, moving positioning device (anchor), a series of thrust spring and by coupling through the integrally formed brake disks of Line concentrator and/or feather key and live axle.This brake disks has single or two braking surface, and wherein, according to basic inventive concept of the present utility model, this break also can comprise the permanent magnet of one or more series.
The model utility content
Speak by the book, the utility model relates to adaptability revision mechanically, so that electromagnetic spring pressure security break can be applicable to dynamically.Such break (being different from the retarder type) generally has two braking surfaces, it comprises the material with high coefficient of friction, this material binds or is mold formed on the both sides of this brake disks, two braking surfaces are guaranteed the braking moment that provides larger, in addition, such break is characterised in that and can discharges preferably and rapidly braking, and has a higher brake operating ability, like this so that this break be particularly suitable for dynamically (when moving part is stopped, and need to brake rapidly and accurately, and make when repeatedly interfering).These breaks are typically applied in: lifting and conveying equipment, transferring machine, electric lift truck, gear motor, encapsulation and wrapping machine, conveying belt machine, high-altitude gantry crane, general hoist and crane gear.
Provide the permanent magnet electromagnetic brake according to the utility model, it comprise at least one electromagnet main body, moving positioning device, a series of thrust spring and by coupling through the integrally formed brake disks of Line concentrator and/or feather key and live axle and a series of permanent magnet that cooperates with electromagnet, to overcome the elastic force of spring.
Preferably, along the vertical shaft of permanent magnet electromagnetic brake and become 180 ° to be provided with two permanent magnets.In a preferred embodiment, the quantity of permanent magnet is four.In another preferred embodiment, permanent magnet is arranged on respect to this vertical shaft approximately on 35 ° the position, and places along the center in the hole of fastening screw trip bolt and the outer distance between the thrust spring.
As previously mentioned, use under special circumstances the utility model principle in " dynamically " break, permanent magnet (it has advantages of suitable size and it is done suitable modification and location) also can bring identical with break in the following preferred embodiment.
These and other objects can realize according to device of the present utility model, this device be characterised in that it consist essentially of electromagnet main body, moving positioning device, a series of thrust spring, with the integrally formed brake disks of live axle and the permanent magnet of one or more series.
Now, in the situation that only limit by way of example and not scope of the present utility model, by simple embodiment of the present utility model these and other features are described apparently.
