Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:
referring to fig. 1, a self-balancing brake capable of preventing vertical installation from generating harmful friction includes a flange 11, a rotor 5, an armature 3 and a stator 1 sequentially arranged from near to far from a motor, a coil 2 and a braking spring 8 are embedded on an end surface of the stator 1 close to the armature 3, a shaft sleeve 7 is connected in the rotor 5, the shaft sleeve 7 is provided with a reducing protruding end portion extending into the flange 11, a supporting spring 9 is sleeved on the reducing protruding end portion of the shaft sleeve 7, the rotor 5 is supported on the supporting spring 9, the supporting spring 9 is clamped between the rotor 5 and a supporting part 10, and the supporting part 10 is hooped on the reducing protruding end portion of the shaft sleeve 7.
In the present embodiment, the supporting spring 9 is a wave spring, but other springs, such as an open disc spring or a tower spring, may be used. The supporting part 10 is a clamp spring, the clamp spring is hooped on the reducing protruding end part of the shaft sleeve 7, the clamp spring and the shaft sleeve are fixedly connected by friction force and used for supporting the supporting spring 9, and the supporting part is convenient to install and reliable in performance. In the present embodiment, the armature 3 is connected to the stator 1 by a hollow solenoid 4. The brake is fixedly arranged on the end face 12 of the motor by adopting a screw 6 penetrating through the stator 1, the hollow solenoid 4 and the flange 11, and is stable and reliable. Friction plates are arranged on two end faces of the rotor 5, so that the braking effect can be enhanced.
The utility model discloses a theory of operation:
when the brake is used for braking, the coil 2 is powered off, the armature 3 presses the rotor 5 to the flange 11 under the action of the brake spring 8, the wave spring 9 is deformed, and the rotor 5 is pressed by the flange 11 and the armature 3 to generate brake torque so as to stop the motor from rotating; when the brake is released, the coil 2 is electrified, the stator 1 attracts the armature 3 to be separated from the rotor 5 against the thrust of the brake spring 8, and the rotor 5 is released to rotate with the motor. At this time, the wave spring 9 returns to the initial state and pushes up the rotor 5 to be separated from the flange 11, and the gap is half of the brake gap.
The utility model discloses a ripples spring 9 supports rotor 5, overcomes rotor 5's gravity, with rotor 5 jack-up, the jack-up distance is half of stopper nominal clearance. The wave spring 9 is supported and fixed by the clamp spring 10 for the shaft, and the locking force of the clamp spring 10 needs to be larger than the gravity of the rotor but smaller than the elastic force of the brake spring 8. When the brake is released, the rotor 5 cannot move downwards because the locking force of the clamp spring 10 is greater than the gravity of the rotor 5, and meanwhile, the rotor 5 is separated from the flange 11 under the action of the resilience force of the wave spring, so that harmful friction and noise caused by the contact of the rotor 5 and the flange 11 are prevented. After the stopper used a period, 5 wearing and tearing of rotor, stopper clearance grow, during the braking, the displacement grow of rotor, supporting spring 9's deformation grow, and supporting spring 9 promotes jump ring 10 and moves down, and the stopper reaches new balanced state, consequently the utility model discloses can realize automatic balance, make the rotor throw off with the flange all the time under free state, and keep the clearance for half in stopper clearance.
Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
