The electromagnetic power failure brake used in the mechanical transmission system has a manual release function, but when a power failure occurs and a manual release is required, the handle cannot be self-locking, so the manual release operation is very inconvenient. In addition, since the spline sleeve is mounted on the rotor in the brake by a tooth fit connection, there is a tooth-side clearance and noise is easily generated.
The purpose of this design is to overcome the shortcomings in the known technology and provide an electromagnetic power failure brake that increases self-locking function and greatly reduces noise.
The purpose of this design is to achieve this:
The original design is to make two sets of through holes and one set of blind holes on a yoke body with threaded holes. The screws are threaded through a set of through holes on the yoke body. Set the adjustment sleeve, install the armature on the adjustment sleeve, install the coupling plate on the screw after the screw passes through the adjustment sleeve, install the rotor with the spline hole between the armature and the connection plate, and install the flower through the spline hole on the rotor Key sleeves, install springs and pins in another set of through holes on the yoke body, install an adjusting nut with a flange that presses the pins through the threaded holes in the yoke body, on the yoke body A spring with the other end mounted on the armature is installed in the blind hole of the magnet. A bolt with a spring is also symmetrically worn in the yoke body through the armature. After the bolts pass through the yoke body, a handle is threaded on the end of the bolt The shaft is connected with a handle on the two outer end faces of the yoke body, and the purpose of this design is achieved based on the through-holes of the handle shaft through the through holes on the two ends of the handle: ① The spline hole of the rotor described above The spline sleeve is installed after the spring leaf is installed by the screw inside; ② on the handle One side of the through hole is made self-locking means on both end surfaces.
The specific connection structure of the self-locking device on one side surface of the through hole on the both end surfaces of the handle is that one side surface of the through hole on both end surfaces of the handle is provided with a limiting groove that communicates with the through hole on the handle. The rear section of the side surface is made into an arc surface concentric with the circle center of the handle shaft.
L 型。 The spring piece installed in the spline hole of the rotor described above can be made into an arc shape, or can be made into an L shape.

The embodiments of the design will be further described in detail below with reference to the drawings:
1 、图 2 和图 3 ，在带有螺纹孔 23 的磁轭体 7 上分别制有两组通孔 19 、 20 及一组盲孔 22 ，在磁轭体上通孔 19 内穿装螺钉 3 ，该螺钉穿出磁轭体的另一端面后，在螺钉上套装调整套 4 ，通过调整套安装衔铁 5 ，螺钉 3 又穿出调整套后，在螺钉上再套装有联接板 2 ，上述的衔铁与联接板之间安装带有花键孔 24 的转子 1 ，为防止齿侧间隙和产生噪音，因此在转子的花键孔内通过螺钉 17 安装 L 型的弹簧片 16 ，然后在转子的花键孔内安装花键套 15 ，这样把花键套与转子间齿侧间隙挤到一侧，从而达到主轴运转时减少噪音的目的。 Referring to FIG. 1 , FIG. 2 and FIG. 3 , two sets of through holes 19 and 20 and one set of blind holes 22 are made on the yoke body 7 with threaded holes 23 , and the through holes 19 are put on the yoke body. Screw 3 , after the screw penetrates the other end surface of the yoke body, set an adjustment sleeve 4 on the screw, install the armature 5 through the adjustment sleeve, and after screw 3 passes out of the adjustment sleeve, set a coupling plate 2 on the screw. The rotor 1 with a spline hole 24 is installed between the armature and the connecting plate . In order to prevent tooth-side clearance and noise, an L -shaped spring leaf 16 is installed in the rotor spline hole by a screw 17 and then the rotor is spun. The splined sleeve 15 is installed in the splined hole , so that the tooth gap between the splined sleeve and the rotor is squeezed to one side, thereby reducing the noise when the spindle is running. 20 内安装弹簧 14 和销子 13 ，通过磁轭体上的螺纹孔 23 安装带有凸缘边 25 的调整母 8 ，调整母上的凸缘边压住销子 13 。 The spring 14 and the pin 13 are connected to the through hole 20 on the yoke body, and the adjusting nut 8 with the flange side 25 is installed through the threaded hole 23 on the yoke body. The flange side of the adjustment nut presses the pin Child 13 . 22 内将弹簧 21 装于其内，弹簧的另一端与衔铁顶装。 A spring 21 is installed in the blind hole 22 on the yoke body , and the other end of the spring is mounted on the armature. 12 的螺栓 11 ，两个螺丝 11 也传出磁轭体，在穿出磁轭体的螺栓端头上都通过螺纹连接有手柄轴 10 ，通过磁轭体上的两外端面连装有一个手柄 6 ，参照图 4 和图 5 ，在手柄两端面上制有通孔 9 ，将手柄轴穿装于手柄上的通孔 9 内，手柄上两端面通孔的一侧面上各制有与手柄通孔相贯通的限位槽 18 ，再将给侧面与磁轭体接触面解除的后一端面 26 处制成圆弧面，其圆弧面的圆心与手柄轴的圆心同心。 It is also mentioned that the bolt 11 with the spring 12 is also symmetrically rotated through the armature in the yoke body . The two screws 11 also pass out of the yoke body, and the handle shaft 10 is connected to the bolt end of the yoke body by threads. A handle 6 is connected to the two outer end surfaces of the yoke body. Referring to FIGS. 4 and 5 , through holes 9 are made on both ends of the handle, and the handle shaft is threaded into the through hole 9 on the handle. Limiting grooves 18 are formed on one side of the upper end surface through-holes and communicate with the handle through-holes , and the rear end surface 26 that releases the contact surface between the side surface and the yoke body is made into an arc surface. The center of the face is concentric with the center of the handle shaft. 18 内，手柄松开能够自锁，这是因为当以磁轭体与手柄接触的接触面为基面开始搬动手柄时，手柄平面与磁轭体接触，且接触点通过磁轭体中心线，所以实现了自锁功能。 The above structure enables the handle to be moved to a certain angle, that is, it is dialed into the limiting groove 18 on the handle, and the handle can be self-locked when it is released. This is because when the contact surface of the yoke body and the handle is used as the base surface, the handle is moved. When the handle is moved, the plane of the handle is in contact with the yoke body, and the contact point passes through the center line of the yoke body, so the self-locking function is realized.
The advantages and positive effects of this design are:
Because spring blades are installed in the spline hole of the rotor and a self-locking device is made on the handle, the design has a clever idea, and the handle can be self-locked when manual release is required in the event of power failure Handle release is very convenient for the purpose. In addition, this design has the characteristics of smooth and reliable braking and reduced noise.
