Armature in the such scheme and middle friction board attachment hole inner bolt are with sliding sleeve outward.
The utlity model has following beneficial effect: this pumping unit electromagnetic brake is owing to take such scheme; utilize the principle of electric magnetisation, finally control input shaft, reach the braking purpose by magnetic force; thereby make compact structure; simple to operate, safe and reliable, stopped the drawback of parking brake; directly press a button and to shut down the arbitrary position; once drop into long-term being benefited, saved maintenance cost, prolonged pumping unit working life.But also can realize the long-range control of shaking, help applying.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-input shaft among the figure, the 2-speed reducer, the 3-geared sleeve, the 4-fixed dam, the two-sided grinding disk of 5-, 6-armature, the 7-magnet ring, the 8-bolt, 9-connects base plate, 10-sliding sleeve, friction board in the middle of the 11-brake spring, 12-.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this pumping unit electromagnetic brake comprises speed reducer 2 and input shaft 1, input shaft 1 is connected with geared sleeve 3 by key, be connected with fixed dam 4 on the geared sleeve 3 right-hand member input shafts 1, by key geared sleeve 3 is connected on the input shaft 1, by fixed dam 4 geared sleeve 3 is fixed on the input shaft 1 again, improves geared sleeve 3 connection safety by fixed dam 4; Geared sleeve 3 external tooths are meshed with two two-sided grinding disk 5 internal tooths, because of two two-sided grinding disks 5 link to each other with input shaft 1 by interior external tooth, therefore by controlling the purpose that two two-sided grinding disks 5 just can reach control input shaft 1; Friction board 12 in the middle of two 5 of two-sided grinding disks are equipped with increases the friction area by middle friction board 12, just increases braking force; Two-sided grinding disk 5 right-hand members are with armature 6 and magnet ring 7 successively on the geared sleeve 3; magnet ring 7 faces corresponding with armature 6 have 2 blind holes at least; the blind hole groove is built-in with brake spring 11, promotes armature 6 by brake spring 11 and compresses two two-sided grinding disks 5, reaches the purpose of shutdown.The radial ringed groove of magnet ring 7 is embedded with field coil, field coil links to each other with the distribution box controller by lead, middle friction board 12, armature 6 and magnet ring 7 by bolt 8 be connected base plate 9 and be connected, connecting base plate 9 is fixed on the speed reducer 2, by connecting base plate 9 middle friction board 12, armature 6 and magnet ring 7 are fixed on the speed reducer 2, be with sliding sleeve 10 outside armature 6 and the middle friction board 12 attachment hole inner bolts 8, make armature 6 and middle friction board 12 easily horizontally slip by sliding sleeve 10.When field coil is switched on, the magnetic field suction armature 6 that field coil produces magnet ring 7, and compression brake spring 11, two-sided grinding disk 5 is with middle friction board 12, armature 6 and be connected base plate 9 disengagements, and braking torque disappears.When field coil cut off the power supply, magnet ring 7 lost magnetic attraction, and brake spring 11 promotes armature 6 and compresses two two-sided grinding disks 5, and two-sided grinding disk 5 is with middle friction board 12, armature 6 and be connected base plate 9 friction braking moments, reaches the purpose of shutdown.
During actual the use, earlier will connect base plate 9 and be screwed in speed reducer 2 with bolt, with key geared sleeve 3 is connected on the input shaft 1 again, fixed dam 4 is connected on input shaft 1 end face then, and then screw penetrated in 6 holes on the magnet ring 7, sliding sleeve 10 is enclosed within on 6 screws again, again sliding sleeve 10 is penetrated successively in armature 6, two-sided grinding disk 5, middle friction board 12 and two-sided grinding disk 5 attachment holes, and make two-sided grinding disk 5 internal tooths and geared sleeve 3 engagements, at last 6 screws are connected and connect on the base plate 9, and cover guard shield, install.At this moment with lead field coil is connected with the distribution box controller.When field coil is switched on, the magnetic field suction armature 6 that field coil produces magnet ring 7, and compression brake spring 11, two-sided grinding disk 5 is with middle friction board 12, armature 6 and be connected base plate 9 disengagements, and braking torque disappears.When field coil cut off the power supply, magnet ring 7 lost magnetic attraction, and brake spring 11 promotes armature 6 and compresses two two-sided grinding disks 5, and two-sided grinding disk 5 is with middle friction board 12, armature 6 and be connected base plate 9 friction braking moments, reaches the purpose of shutdown.Utilize the principle of electric magnetisation like this; finally control input shaft 1 by magnetic force; reach the braking purpose, thereby make compact structure, simple to operate; safe and reliable; stop the drawback of parking brake, directly pressed a button and to shut down the arbitrary position, once dropped into long-term being benefited; save maintenance cost, prolonged pumping unit working life.But also can realize the long-range control of shaking, help applying.This pumping unit electromagnetic brake has structure and simple to operate thus, and is safe and reliable, and fixed point is stopped the characteristics of simple operation.
