The specific embodiment
Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effects apparent by the specific embodiment of the present invention is described in detail.
The invention provides a kind of roller shutter drive unit, comprise motor and electromagnetic brake.Motor is used for rotating directly or indirectly the spool of roller shutter, makes roller shutter be wound up into spool or unfolds from spool, and described roller shutter can be the flexibility curtain that can curl, door curtain, screen etc., also can be rolling door.Electromagnetic brake is connected with the rotating shaft of motor, and lock out motor when motor stops to prevent that motor from rotating, thereby roller shutter is remained on the position of wanting.
Fig. 1 is the decomposing schematic representation of the roller shutter drive unit of one embodiment of the invention.This roller shutter drive unit comprises gear-box 10, motor 30 and electromagnetic brake 50.Gear-box 10 comprises shell 11, end cap 13 and is installed in gear in the shell 11 that end cap 13 is fixed to shell 11 by screw 12.Gear-box 10 is installed to the front end of motor 30, is used to drive spool as deceleration device and rotates.Motor 30 comprises stator and rotor, and stator comprises shell 32 and end cap 33 etc., and rotor can be with respect to the stator rotation and by rotating shaft 31 driving gearboxs 10.Motor 30 is connected to external power source by lead 34.Electromagnetic brake 50 is installed to the rear end of motor 30, is used for braking motor when motor stops, and prevents that the rotating shaft 31 of motor from rotating when motor stops.Spiral piping arrangement is arranged in the electromagnetic brake, and in use, spiral piping arrangement and motor are switched on simultaneously, outage simultaneously.In the present embodiment, solenoidal line end 55 is in parallel with the line end 34 of motor.
Fig. 2 is the exploded perspective view of electromagnetic brake 50 shown in Figure 1, and Fig. 3 is the end-view of electromagnetic brake 50, and Fig. 4 is the schematic diagram that electromagnetic brake dissects along the A-A face.Extremely shown in Figure 4 as Fig. 2, electromagnetic brake comprises shell 51, end cap 60 and installation tumbler 58, friction member 57, spring 56 and spiral piping arrangement in the enclosure, wherein, spiral piping arrangement comprises iron core 52, is set in iron core outer coil holder 54 and coil 63 thereof.End cap 60, tumbler 58, friction member 57 and spiral piping arrangement be axially-aligned in turn.Tumbler 57 is the dish shape, and has air gap between the end cap 60 so that rotate.The rotating shaft 31 of motor 30 pass electromagnetic brake end cap 60 and with through hole 59 interlocks of tumbler 58, tumbler 58 can be rotated together along with rotating shaft 31.Preferably, the through hole 59 of tumbler 58 is positioned at the center of tumbler 58, and the cross section of through hole has corresponding shape and through hole coupling for the square hole of being with fillet or the hole that has two flat positions, the cross section of driving shaft 31.
Tumbler 58 has a rubbing surface near friction member 57, and this rubbing surface is basically perpendicular to rotating shaft 31.In the present embodiment, friction member 57 is plane or the dish shape, can move axially within the specific limits, and 56 pairs of friction members 57 of axial arranged helical spring apply elastic force, makes the attrition surface friction of friction member 57 and tumbler 58, realizes the braking to tumbler 58.When tumbler 58 is braked, rotating shaft 31 can not rotate, thereby prevent that roller shutter from undesired slip taking place.The rubbing surface of tumbler 58 can be its dish face, also can be from the protruding vertically formed plane of flange, the edge of tumbler 58.
