Embodiment
The specific embodiment of a kind of taper braking motor of the present utility model such as Fig. 1, shown in Figure 2, correspondence is provided with taper stator 2 and the cone rotor 3 that cooperatively interacts in the casing 1 of taper braking motor, motor shaft is installed in the casing 1 in axial sliding, the end that motor shaft is positioned at cone rotor 3 big ends is a clutch end, on casing 1, be coaxially arranged with a taper Brake Block 4 near the small end place of cone rotor 3, between motor shaft and this taper Brake Block 4 for being slidingly matched and on motor shaft, radially being set with the bearing that is rotatably assorted with it, on the motor shaft in taper Brake Block 4 outsides, radially be fixed with the taper brake disc 6 of corresponding matching, in the present embodiment, be wholely set radiator shutter 7 on the outer face of this taper brake disc 6, be provided with motor fan housing 8 in the outside mask of radiator shutter 7.The coaxial outer cover 9 that is fixed with on the outer face of motor fan housing 8, motor shaft extends axially and passes motor fan housing 8 and extend in the outer cover 9, end at motor shaft is rotatably equipped with a terminal pad 10 by the shaft shoulder and locking nut 14 location, the coaxial release screw rod 12 that is installed with of corresponding motor shaft on outer cover 9, this release screw rod 12 is provided with at interval with motor shaft, leave spacing therebetween, the inner end radial location that is positioned at outer cover 9 at release screw rod 12 is rotatably equipped with a unsteady link 11, the link 11 upper edge circumference that float evenly are provided with at least two linking arms that axially extend towards terminal pad 10 directions, each linking arm towards the end of terminal pad 10 be vertically installed with respectively extend towards motor shaft in turn edge, be respectively arranged with the thimble 13 that cooperates away from a side end face roof pressure that discharges screw rod 12 with terminal pad 10 on turning edge in each linking arm.
This taper braking motor is when the energising running, owing to can produce a kind of electromagnet pull between stator and the rotor, the pressure that makes cone rotor 3 be pullled by electromagnet pull when energising is rotated and overcome compression spring 5 is near taper stator 2, cone rotor 3 promotes taper brake disc 6 by motor shaft and breaks away from taper Brake Block 4, and the interior brake apparatus of motor this moment lost efficacy; When outage, the electromagnet pull between taper stator 2 and the cone rotor 3 is zero, and compression spring 5 pushing motor axles move axially and make cone rotor 3 leave taper stator 2, and simultaneously, motor shaft drives taper brake disc 6 and realizes braking near taper Brake Block 4.But when needing to discharge the brake apparatus of motor, turn release screw rod 12 by spanner, discharge screw rod 12 and spur the terminal pad 10 that is installed on the motor shaft by the link 11 that floats, driving motor shaft by terminal pad 10 moves axially, make to produce between taper brake disc and the taper Brake Block and become flexible, thereby dynamic braking device is discharged, and motor is driven under slight braking state by load and slowly rotates.If motor rotates too fast or discharges when finishing, can instead twist release screw rod 12, make the link 11 that floats break away from terminal pads 10, motor shaft resets under the effect of compression spring 5 and recovers on-position again.Because all being encapsulated in, terminal pad 10 and unsteady link 11 be difficult in the outer cover 9 observe, rotate with discharging screw rod 12 for the ease of the operating mode of concluding motor and the link 11 that prevents to float, the utility model link 11 that also floats is provided with at least one check post 16 parallel with discharging screw rod 12, and check post 16 extends axially and passes the inspection hole 15 that correspondence is offered on the outer cover 9.In the present embodiment, on the link 11 that floats symmetry be provided with two linking arms, and corresponding two linking arms are provided with two check posts 16, corresponding inspection hole can be to be the long arc-shaped holes in the center of circle or the diameter through hole greater than the check post with the motor.In the operating process, if check post 16 can freely swing, illustrate that two thimbles 13 on the floating bracket have broken away from and the contacting of terminal pad 10, motor is in normal operating conditions, and releasing device does not influence the braking of motor; When check post 16 can not freely swing, illustrate that the thimble 13 on the link 11 that floats has withstood the terminal pad 10 on the motor shaft, motor is in brake release state or abnormal operating state.The size that discharges screw rod 12 corners can directly have influence on the braking moment of motor, thus the speed that control load descends.
The utility model is not limited to the foregoing description, wherein, the terminal pad of installing on the motor shaft can directly be fixedly mounted on the motor shaft, unsteady link also can directly be fixed on and discharge on the screw rod, as long as in float link and the terminal pad one is rotatably assorted with corresponding release screw rod or motor shaft and just can realizes identical effect; Other conventional syndetons such as the link that floats can also adopt clamping with the structure that is in transmission connection between the terminal pad except that roof pressure cooperates, be spirally connected; Thereby outer cover also can adopt the U-shaped supporting structure or observation window is set on outer cover and omit the check post except that full-closed structure; More than all distortion all be that those skilled in the art are easy to expect, all within protection range of the present utility model.
The concrete structure of safe release device of the present utility model has a detailed description in the above, repeats no more herein.
