Abstract
The utility model discloses a no-disc sleeve brake of a shell rotating motor, relating to the technical field of electric and automatic executive elements. The no-disc-sleeve brake comprises a magnetic yoke, wherein the magnetic yoke is internally provided with a coil; the left side of the coil is provided with an armature, and the left side of the armature is provided with a friction piece; a spring is arranged between the armature and the magnetic yoke; a positioning pin is arranged below the left side of the magnetic yoke; one end of the spring presses the armature tightly, and the other end of the spring extends into a spring hole of the magnetic yoke; and a screw is screwed into the right end of the spring hole. The no-disc-sleeve brake has the advantages that the structure design is reasonable; the main function is as follows: when a motor shaft does not rotate and the outer shell rotates, the brake can realize reverse braking; the structure is compact, the installation is convenient, the noise is low, the working frequency is high, the action is sensitive and the braking is reliable.
Description
Technical field:
The utility model relates to electric automatization executive component technical field, and relating in particular to a kind of housing electric rotating machine does not have dish cover break.
Background technique:
Break is to have to make moving element (or movable machinery) slow down, stop or keeping the device of functions such as halted state.Be the mechanical parts that make the movement parts in the machinery stop or slowing down.The electromagnetism power-off brake breaks away from (release) for energising, the frictin braek of spring to break braking.Be widely used in the machineries such as metallurgy, building, chemical industry, food, lathe, printing, packing, reach occasions such as when outage, (preventing by inches) braking.This break has compact structure, easy for installation, wide adaptability, noise is low, frequency of okperation is high, be active in one's movements, brake advantages such as reliable, is a kind of desirable automation executive component.
The conventional brake device is generally axle rotation, is connected axle with brake disc through spline housing, the outage rear brake through with the brake disc friction, produce moment, the prevention motor shaft rotates, and reaches the purpose that equipment is stopped.But this kind break Applicable scope has certain narrow limitation, can not satisfy at motor shaft and not rotate, and uses under the situation of frame rotation.
The model utility content:
The utility model technical problem to be solved is to overcome the defective of existing technology, provides a kind of housing electric rotating machine not have dish cover break.
The utility model technical problem to be solved adopts following technological scheme to realize:
The housing electric rotating machine does not have dish cover break, it is characterized in that: comprise yoke, be provided with coil in the yoke; The coil left side is provided with armature; The armature left side is provided with friction plate, is provided with spring between said armature and the yoke, and below, said yoke left side is provided with locating stud.
Said spring one end presses armature, and an end puts in the spring eye of yoke, and the spring eye right-hand member has adjusting screw to screw in.
Meshing through on the motor shaft of this break is fixed on the break yoke on the motor shaft, and break discharges during energising; The rotation of motor housing body, during outage, the brake spring pressurization; Make the friction of armature upper friction plate and brake shell body; Produce moment, frame is stopped the rotation, reach the braking purpose.
The utility model reasonable in design, its major function is not rotate at motor shaft, in frame when rotation,, this break can be realized reverse brake, compact structure, easy for installation, noise is low, frequency of okperation is high, it is reliable to be active in one's movements, to brake.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the housing electric rotating machine does not have dish cover break, comprises yoke 6; Be provided with coil 5 in the yoke 6, coil 5 left sides are provided with armature 1, and armature 1 left side is provided with friction plate 2; Be provided with spring 3 between said armature 1 and the yoke 6, below, said yoke 6 left sides is provided with locating stud 7, and spring 3 one ends press armature 1; One end puts in the spring eye of yoke 6, and the spring eye right-hand member has adjusting screw 4 to screw in.
Meshing through on the motor shaft of this break is fixed on break yoke 6 on the motor shaft, and break discharges during energising; The rotation of motor housing body, during outage, brake spring 3 pressurizations; Make the friction of armature 1 upper friction plate and brake shell body; Produce moment, frame is stopped the rotation, reach the braking purpose.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
