Description
Technical field
The utility model relates to a kind of brake gear of direct-current tubular motor.
Background technology
Tube shaped electric machine has as drive unit that compact conformation, torque are big, rotating speed waits advantage slowly, so tube shaped electric machine is applied in the products such as the electronic roll-type window or door of finishing elevating movement, shading system, projection screen more and more.The phenomenon that glides takes place because of deadweight for preventing to be driven parts such as rolling screen door, elimination is inaccurate because of the location that the effect of inertia of rotor high-speed after rotating causes, guarantee that rolling screen door can be out of service and rest on this position at once in the moment of cutting off the electricity supply, make rolling screen door have the fail safe of self-lock ability and use, tube shaped electric machine all needs to be provided with a kind of brake device.
The tube shaped electric machine that has adopts the braking system of using to be conical surface braking system, has the defective of difficulty of processing height, poor reliability.Direct-current tubular motor adopts armature as brake(-holder) block mostly, the armature mode that directly compresses stage clip realizes braking, the one side of brake(-holder) block can cooperate with brake disc by brake spring, one side cooperates with the electromagnetic brake end face, when not having electricity, solenoid in the electromagnetic brake does not have suction, under the effect of brake spring, brake(-holder) block is moved forward, brake(-holder) block is close to and is withstood brake disc on the brake, it is checked do not rotate, and drive axle of motor is stopped operating reach the purpose of braking again by brake disc, when being arranged, electricity make brake(-holder) block break away from brake disc, motor normal rotation.The brake apparatus that is to say existing direct-current tubular motor mainly comprises electromagnet, armature and spring four big parts.Because of having only single-sided friction power between armature and the brake disc, armature is monolithic metal in addition, and coefficient of friction is less, and frictional force is also less.Generally through have work about 3000 times after, the skidding degradation, thus cause the decline of tube shaped electric machine overall performance, and the unusual difficulty of maintenance, transposing brake block.
As a patent No. is the brake of a kind of tube shaped electric machine the Chinese utility model patent " brake of tube shaped electric machine " of ZL03231887.1 (notification number is CN2622916Y) has disclosed, be installed in the rolling screen door axle housing and be used with the roller shutter motor, by being connected with the unshakable in one's determination of spring and being fixed on the roller shutter motor shaft, brake(-holder) block with braking action cooperates with elastic braking plate, and be installed in the axle housing and constitute, also be connected with magnetizing coil on the iron core, and magnetizing coil and the switching simultaneously of roller shutter motor.
Summary of the invention
Technical problem to be solved in the utility model is the brake gear that a kind of direct-current tubular motor of simple and reasonable and good braking effect is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of brake gear of direct-current tubular motor, comprise tube shaped electric machine body and the brake mount that is fixed on tube shaped electric machine body one side, it is characterized in that: the electromagnet with the synchronous power on/off of tube shaped electric machine body is installed in the described brake mount, being connected with in the rotating shaft of described tube shaped electric machine body can be with rotating shaft spin brake dish, being provided with between described electromagnet and the brake disc can be by the armature disc of electromagnetic actuation, held spring between described electromagnet and the brake disc, described brake disc is realized braking between the preceding inwall that is pressed in armature disc and brake mount under the effect of spring.
As improvement, above-mentioned armature disc is double-deck disk body, and wherein, over against the adhesive layer of one deck for being made by mild steel of electromagnet, the one deck over against brake disc in the armature disc is the frictional layer of being made by polyphenyl thioether material in the armature disc.
During use, the adhesive layer of being made by mild steel can guarantee adhesive good between armature disc and the electromagnet, the frictional layer of being made by polyphenyl thioether material then can increase coefficient of friction between armature disc and the brake disc, increase the braking ability of this brake gear, this compound armature disc heat transfer property is poor in addition, can not cement phenomenon with brake disc, separate easily, improved the sensitivity of braking, thereby improved the overall performance of tube shaped electric machine, surface temperature is low when working because of frictional layer again, and brake disc is difficult for aging, has prolonged its useful life again.
Above-mentioned brake disc is for to form disk-like structure by the very high silicon rubber die casting of coefficient of friction.Little in the spring force effect, the polyphenylene sulfide engagement in a plane and the armature disc, the preceding inwall engagement of another plane and brake mount, two planes produce frictional force simultaneously, strengthen braking ability greatly.
Form a plurality of radially guide vane end stops of projection on the perisporium of above-mentioned armature disc, have many stopper slots that match with guide vane end stop on the sidewall of described brake mount vertically, described guide vane end stop is positioned at stopper slot and only can axial slip.Because cooperating of guide vane end stop and stopper slot makes armature disc by circumferentially spacing, when armature disc and brake disc compressed, armature disc can not spin, enhancing braking effect and job stability.
Be fixed with the adapter sleeve that is gear-like in the rotating shaft of above-mentioned tubulose motor body, the center position of described brake disc has the connecting hole that matches with the adapter sleeve profile, and described brake disc is set on the adapter sleeve.
Form three reference columns that are provided with along the circle spacing on the front end face of above-mentioned electromagnet coil skeleton, described spring has three, and an end of each spring is set on the reference column, and the other end of spring then holds on armature disc.Adopt many little springs can make spring stressed more even to armature disc, spring is to the easier adjusting of pretightning force of armature disc in addition.
Compared with prior art, advantage of the present utility model is: the part that this brake gear relates to is few, and each design of part is simple, and shape is single, and easily processing has magnetizing coil in the electromagnet, and the suction of generation is big, and is highly sensitive, and braking ability is good.
