Description
Technical field
The invention belongs to limiter of moment technical fields, and in particular to a kind of limiter of moment with overload protection.
Background technique
Limiter of moment is a kind of component for coupling mover and working machine machine, can be divided into frictional torque by working principle
Limiter and ball-type limiter of moment (steel-ball type limiter of moment), are mainly used in electronics industry, automated production
Line, conveyer industry etc., existing limiter of moment defencive function is not strong, especially in load excessive, cannot protect power
Output equipment, therefore limiter of moment needs overload protection function extremely important.
Summary of the invention
The purpose of the present invention is to provide the limiters of moment for overload protection, to solve to play guarantor in overload work
The problem of protecting motive power outputting apparatus.
To achieve the above object, the invention provides the following technical scheme: a kind of limiter of moment for overload protection, packet
Include driving disc spacing pressing, driving shaft, ball groove, ball, reseting disk, dial, fixed disk, driven axle and power source, the driving shaft
Driving disc spacing pressing is connected by expansion sleeve, the driving disc spacing pressing is fixedly connected to be set with no backlash engaging mechanism, the no backlash engaging mechanism
It is equipped with ball groove, the ball groove spacing is equal, and the ball is identical with ball number of recesses, can closely connect, nothing
Gap, described to be connected close to switch setting with reseting disk, the dial is arranged among fixed disk and reseting disk, the fixation
Disk is connected with driven axle by fiting device.
Preferably, the driving shaft and driving disc spacing pressing are connected by fiting device.
Preferably, the close switch is capacitive approach switch.
Preferably, the position-arresting disk is identical with no backlash engaging mechanism diameter.
Preferably, the power source is that can provide driving force mechanisms.
Technical effect and advantage of the invention: this is used for the limiter of moment of overload protection, when driven axle and driving shaft
When revolving speed difference, ball and ball groove are scratched, and driving disc spacing pressing and driven disc separation issue separation signal, this signal close to switch
Control panel is passed to, to control or cut off the power, has the function that protect equipment.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
In figure: 1- driving disc spacing pressing, the close switch of 2-, 3- driving shaft, 4- ball groove, 5- ball, 6- reseting disk, 7- dial, 8-
Fixed disk, 9- driven axle, 10- power source, 11- is without backlash engaging mechanism.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of limiters of moment for overload protection, including driving disc spacing pressing, active as illustrated in the drawing
Axis, ball groove, ball, reseting disk, dial, fixed disk, driven axle and power source, the driving shaft 3 are connected by expansion sleeve
Driving disc spacing pressing 1 is connect, the driving disc spacing pressing 1, which is fixedly connected, is provided with rolling with no backlash engaging mechanism 11, the no backlash engaging mechanism 11
Pearl groove 4,4 spacing of ball groove is equal, and the ball 5 is identical with 4 quantity of ball groove, can closely connect, continuously
Gap, described to be connected close to the setting of switch 2 with reseting disk 6, the dial 7 is arranged among fixed disk 8 and reseting disk 6, described
Fixed disk 8 is connected with driven axle 9 by fiting device, and driving shaft 3 is connect with driving disc spacing pressing 1 by fiting device, most of
In the case of close to switch 2 be condenser type, the reseting disk 6 of limiter of moment is identical with no 11 diameter of backlash engaging mechanism, meanwhile, it is dynamic
There are many kinds of the presentation modes in power source 10, can be motor, and a variety of with the type of attachment of driving disc spacing pressing 1, axis and sprocket wheel, axis and
Many installation forms such as axis, axis and flange.
Working principle: connection power source 10 first, the mechanism that the connection of driven axle 9 needs to be driven, when the output of power source 10 is dynamic
Power drives driving shaft 3 to rotate, and when normal work, ball 5 and ball groove 4 are closely connected, and driven axle 9 and driving shaft 3 are mutually synchronized
Degree rotation, when the revolving speed difference of driven axle 9 and driving shaft 3, ball 5 and ball groove 4 are scratched, and driving disc spacing pressing 1 and driven disc 8 divide
From close to the separation signal out of hair 2 is switched, this signal passes to control panel, to control or cut off the power, reaches protection equipment
Effect.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
