Abstract
The utility model belongs to the field of a motor, and specifically discloses a novel rotor brake mechanism. The novel rotor brake mechanism is characterized in that a brake cover plate is arranged at the extension segment of a motor housing; a brake disc mounting frame is arranged between an end cover and the brake cover plate; the brake disc mounting frame is arranged on a rotor shaft in a sliding mode; a brake disc is arranged between the brake disc mounting frame and the brake cover plate; an annular iron core is arranged in the brake disc mounting frame in an embedded mode; the annular iron core is fixed to the brake disc mounting frame through a top block; the rotor shaft is provided with a cylindrical pin for limiting the top block; the cylindrical pin is arranged on the rotor shaft in a sliding mode; and a reset spring is arranged on the rotor shaft between the cylindrical pin and the end cover. According to the utility model, the tail end of the rotor shaft is provided with a brake mechanism, when a motor is energized, a magnetic force is generated to absorb the annular iron core to approach a rotor, such that the brake disc is separated from the brake cover plate, and the mechanism does not work; and when power is off, the magnetic force disappears, the whole brake disc mounting frame is reset under the effect of the reset spring so that the brake disc can be contacted with the brake cover plate.
Description
Technical field
The utility model belongs to machine field, is specially a kind of novel rotor braking mechanism.
Background technology
Existing motor internal does not all have braking mechanism, be all that auxiliary body realizes brake outside, while so just causing motor to use, take large quantity space, even motor small size, also can occupy because of corollary equipment large stretch of area, the motor that therefore designs a kind of strap brake structure is just very necessary.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of novel rotor braking mechanism.
Described novel rotor braking mechanism, comprise electric machine casing, end cap, rotor, stator and armature spindle, this rotor braking mechanism is arranged on the extension that armature spindle is positioned at end cap outside, it is characterized in that described rotor braking mechanism is by brake block, brake block installing rack, brake cover plate, straight pin, jacking block, ring-type iron core and back-moving spring composition, brake cover plate is arranged on the extension of electric machine casing, between end cap and brake cover plate, brake block installing rack is set, brake block installing rack is slidably arranged on armature spindle, brake block is arranged between brake block installing rack and brake cover plate, in brake block installing rack, interlocking arranges ring-type iron core, ring-type iron core is fixed by jacking block and brake block installing rack, on armature spindle, be provided with the straight pin of spacing jacking block, straight pin is slidably arranged on armature spindle, back-moving spring is arranged on the armature spindle straight pin and end cap through ring-type iron core.
Described novel rotor braking mechanism, is characterized in that described brake block, brake block installing rack, ring-type iron core, jacking block and straight pin move along armature spindle one.
The utility model arranges braking mechanism at armature spindle end, produces magnetic-adsorption ring-type iron core close to rotor place when electrical power, and brake block will separate with brake cover plate like this, and braking mechanism is inoperative; In the time of power-off, magnetic force disappears, and whole brake block installing rack can reset under action of reset spring, and brake block is contacted with brake cover plate, realizes brake.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-armature spindle, 2-rotor, 3-end cap, 4-electric machine casing, the 5-cover plate that brakes, 6-brake block, 7-brake block installing rack, 8-ring-type iron core, 9-straight pin, 10-jacking block, 11-back-moving spring.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail:
