Abstract
A double-sided brake of tubular motor comprises a front bearing base with a bearing and a brake holder mounted thereon; the bearing base is connected with the rotor shaft of a motor through snap spring; a stator with a stator cover matching the rotor; the rotor is provided with a rotor shaft; a brake disk provided with a spring matches the brake holder. All of above elements are mounted in a housing. The brake holder consists of an upper brake combination connected with middle brake combination, and the brake disk is the lower brake combination, which is directly mounted on the rotor shaft. A magnet is provided on one end face of the rotor to make the rotor combination match with the stator. The utility model obviates the need of iron core with excitation coils, and has compact structure, light weight, good performance, stable operation and fast braking speed.
Description
Technical field
The utility model relates to the vitals in a kind of tube shaped electric machine, is used to guarantee the accurately tube shaped electric machine double-sided braking brake of braking work use of tube shaped electric machine.
Background technology
Behind the dump of tube shaped electric machine, because of the effect of inertia rotor after the rotor high-speed rotation still can rotate, the rolling screen door that is pulled up simultaneously causes the location inaccurate because of deadweight also can take place to glide, be the reliability and the safety in utilization of the self-lock ability of guaranteeing rolling screen door, the brake of tube shaped electric machine, brake apparatus play a part crucial.
The patent No. 03231887.1 " brake of tube shaped electric machine " is though also provide a kind of rapid, safe and reliable brake of braking, and still there are some defectives in it, particularly can produce skidding when overload operation, and only is a kind of single face brake structure.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of tube shaped electric machine double-sided braking brake is provided, and the compact conformation volume is little, and the brake stationary vibration is little, and braking is used safety and reliability rapidly, has prolonged useful life.
The technical scheme in the invention for solving the above technical problem is: the brake of tube shaped electric machine double-sided braking, by bearing is installed, the front-end bearing pedestal of brake mount is connected with jump ring with the armature spindle of motor, the motor stator of band stator sheath cooperates with the rotor of band armature spindle, the brake disc of band spring cooperates with brake mount to install and forms in the enclosure, described brake mount is made up of the brake combination of going up of brake combination in being connected with, described brake disc is brake combination down, the following brake combination of band spring is directly installed on the armature spindle, is connected with the combination of suction iron formation rotor on rotor one end face of described band armature spindle and cooperates with motor stator.
Compared with prior art, advantage of the present utility model is: the former iron core that the band magnetizing coil also is installed outside the brake disc of band spring, electromagnetic force by its generation is used for adsorbing brake disc, now this part is all saved, only on the rotor of rotor combination, increase and inhale iron, adsorb brake combination down, make full use of motor power and make its a tractor serves several purposes with the electromagnetic force that motor directly produces, and compact conformation, volume are little in light weight, the few good reliability of part.Brake component is constituted by the upper, middle and lower brake, and the spline housing of the following combination of braking is connected with the splined shaft of last brake combination, and middle brake combination is moved along the opening on the front-end bearing pedestal is upper and lower, and adhesive, disconnection steadily can not rocked, and use safer, reliable.Adopt simultaneously the double-sided braking structure again, increase rubbing surface and increased frictional force again, the following brake combination of band brake spring and in, go up the brake combination and all be directly installed on the armature spindle, basic synchronization is carried out in case outage moment braking at once and rotor stop operating, retro-speed is fast, good braking effect, and this structure can both be worked under low voltage condition smoothly.

Embodiment
Embodiment is further described the utility model below in conjunction with accompanying drawing.
Following brake combination 7 is pressed into the integral body of being with spline housing by nonmetal parts and bottom pure iron nested 9, as shown in Figure 7.
1 time end periphery of front-end bearing pedestal has four uniform openings 16.
Rotor makes up on the armature spindle 11 of inhaling iron 10 places in 12 ends and is with spring 8, one end of armature spindle passes down brake combination 7 respectively and the outer brake of going up that is with middle brake combination 6 makes up 4, on, following brake combination utilizes the splined shaft on it, cover is connected, the front-end bearing pedestal 1 that bearing 3 is installed is enclosed within outside each brake combination, four spline tooths in the middle brake combination cooperate with the opening 16 of front-end bearing pedestal 1 lower end, armature spindle and bearing 3 tight fits are used, shape jump ring 17 will be fixing bimester of following, with jump ring 2 bearing 3 is connected on the front-end bearing pedestal 1, the motor stator 13 that two ends have a stator sheath 15 is enclosed within outside the rotor combination 12, and armature spindle 11 hold and held 3 rear bearing block with tape spool and be connected and put into motor housing 14 formations.
During use, motor stator 13 energising rotor combinations 12 are rotated, inhale the electromagnetic attraction of magnetic field, iron 10 place generation greater than spring 8 power by armature spindle, then rotor combination 12 sucks down brake combination 7, and brake combines rotation under driving, and the while is made up 4 also rotations with the upward brake that following brake is connected together, and at this moment each brakes and leaves the gap between combination, the work of motor normal rotation, as shown in Figure 1.
If motor quits work or cuts off the power supply, armature spindle is inhaled the no suction of iron 10 places outage, under spring 8 power effects, make brake combination 7 down leave rotor end-face, following brake combination 7 moves up to brake in being close to and makes up 6, and the brake combination moves up up to being close to brake combination 4 along the opening 16 on the front-end bearing pedestal 1 in promoting, middle brake combination only can be upper and lower mobile, can not rotate, splined shaft 18 in the last brake combination 4 is connected with the spline housing of brake combination 7 down, the three is close together under spring 8 effects, as shown in Figure 2.
The two sides braking brake has increased friction area and frictional force, and retro-speed is fast, good braking effect.
