The invention discloses an anti-reverse-rotation device of a motor. The anti-reverse-rotation device of the motor comprises a rotating disk, a fixing piece and a stop pin. The anti-reverse-rotation device of the motor is characterized in that an installation part extends from one side of the rotating disk, a through hole for containing the stop pin is formed in the installation part, the stop pin is assembled on the installation part through an installation rack, an elastic part is arranged between the stop pin and the installation rack, the fixing piece is matched with the stop pin and is fixedly arranged on a motor end cover, and a reverse-rotation stopping part is arranged on the side surface of the fixing piece which is matched with the stop pin. The anti-reverse-rotation device of the motor has the advantages that the frequent replacement of the stop pin due to friction can be avoided as long as the pushing force of the elastic part and the centrifugal force of the stop pin are properly calculated, the maintenance cost of the motor is reduced and the motor is prevented from producing huge noise during operation.
Description
Technical field
The present invention relates to a kind of motor, relate in particular to a kind of motor for preventing inversion set.
Background technology
At present, in electromechanics trade, some motor need to be with anti-reverse-rotation device, prevents that motor reversal from bringing injury to equipment.Anti-reverse-rotation device on motor divides two kinds of electromagnetic relay structure and pure mechanical structures conventionally.Because electromagnetic relay structure needs energising in addition, and power supply conventionally not identical with motor main power source, do not mate, so the employing of general motor manufacturing company is pure mechanical structure.Refer to shown in Fig. 1, Fig. 1 is the structural representation of traditional Purely mechanical motor for preventing inversion set, traditional Purely mechanical motor for preventing inversion set comprises rotating disk 10, on one side of described rotating disk 10, be provided with several scotchs with slope 11, coordinate scotch 11 by fixture 12, to be provided with latch 13 in a side of rotating disk 10, during the 10 normal rotation of motor rotating disk, scotch 11 rotates together with rotating disk 10, utilize the slope on scotch 11, make latch 13 can cross scotch 11.If but when reversion, because scotch 11 reverse side are without slope, latch 13 will withstand scotch 11, thereby rotor is stopped operating.
The shortcoming of said structure in application is: each latch 13 frictions and whereabouts all can produce noise; Require the material of latch 12 not easy to wear, rubbing surface smoothness requires high; Latch 12 is high at up process medium velocity simultaneously, strength is large, easily breaks cover plate.Cause customer complaint, even return goods.
Summary of the invention
The object of the present invention is to provide a kind of motor for preventing inversion set, it can avoid friction to cause the replacing of latch, produces huge noise while avoiding motor operation.To solve the problems referred to above that in prior art, motor for preventing inversion set exists.
For reaching this object, the present invention by the following technical solutions:
A kind of motor for preventing inversion set, it comprises rotating disk, fixture and latch, wherein, described rotating disk is extended with installation portion to a side, on described installation portion, offer the through hole for accommodating latch, described latch is assemblied on installation portion by installing rack, and described latch is provided with elastomeric element between installing rack, described fixture coordinates latch to be fixed on electric motor end cap, and described fixture coordinates latch on its side, to be provided with reverse stop component.
Especially, described reverse stop component adopts integrative-structure, and it comprises circular body, offers clockwise or counterclockwise several slips that are connected domatic in described body outer rim, and the domatic end of described slip is provided with anti-reverse seam.
Especially, described installing rack comprises two connecting bolts and mounting panel, and the interval, one end of described two connecting bolts is connected on described installation portion and uses nut check, and the other end is fixed with mounting panel by nut, on described mounting panel, be fixed with connecting rod, the end of described connecting rod connects latch.
Especially, described elastomeric element is helical spring, and described helical spring is arranged on described connecting rod, and one end is against latch, and the other end is against mounting panel.
When motor has just started to rotate, elastomeric element is pushed down latch, makes latch utilize domatic slip of slip on fixture.When rotating speed reaches a certain value, utilize the centrifugal force of rotating disk, overcome the thrust of elastomeric element, make latch leave fixture.When motor stops, the thrust of elastomeric element will be pushed down latch again, and the latch again slip on fixture slides on domatic.When motor reversal, latch will block with fixture, stop motor reversal.
Beneficial effect of the present invention is, as long as compared with prior art described motor for preventing inversion set has been calculated the centrifugal force of elastomeric element thrust and latch, just can avoid friction to cause the frequent replacing of latch, reduce the maintenance cost of motor, and can avoid motor when operation to produce huge noise.

Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate technical scheme of the present invention.
Refer to shown in Fig. 2 and Fig. 3, Fig. 2 is the structural representation of the motor for preventing inversion set that provides of the specific embodiment of the invention 1, and Fig. 3 is that the A of Fig. 2 is to view.
In the present embodiment, a kind of motor for preventing inversion set comprises rotating disk 20, fixture 21 and latch 22, described rotating disk 20 is extended with installation portion 23 to a side, on described installation portion 23, offer the through hole for accommodating latch 22, described latch 22 is assemblied on installation portion 23 by installing rack, described installing rack comprises two connecting bolts 24 and mounting panel 25, the interval, one end of described two connecting bolts 24 is connected on described installation portion 23 and uses nut check, the other end is fixed with mounting panel 25 by nut, on described mounting panel 25, be fixed with connecting rod 26, the end of described connecting rod 26 connects latch 22, and be equipped with helical spring 27 on described connecting rod 26, one end of described helical spring 27 is against latch 22, the other end is against mounting panel 25.
Described fixture 21 coordinates latch 22 to be fixed on electric motor end cap, and described fixture 21 coordinates latch 22 on its side, to be provided with reverse stop component 28, described reverse stop component 28 adopts integrative-structure, it comprises circular body 29, in described body 29 outer rims, offer along clockwise direction several slips that are connected domatic 30, the end of described slip domatic 30 is provided with anti-reverse seam 31.Certain described slip domatic 30 also can be arranged in the counterclockwise direction.
When motor has just started to rotate, helical spring 27 is pushed down latch 22, makes latch 22 utilize the slip domatic 30 on fixture 21 to slide.When rotating speed reaches a certain value, utilize the centrifugal force of rotating disk 20, overcome the thrust of helical spring 27, make latch 22 leave fixture 21.Frequent friction to latch 22 while avoiding rotating disk 20 High Rotation Speed, when motor stops, now the elastic force of helical spring 27 is greater than the centrifugal force of rotating disk 20, and the thrust of helical spring 27 will be pushed down latch 22 again, and latch 22 slides in the slip on fixture 21 domatic 30 again.When motor reversal, latch 22 by with fixture 21 on the blocking of anti-reverse seam 31, stop motor reversal.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
