It is an object of the present invention to a kind of elastic ring transmission device is designed, structure novel, in mechanism operational process
In, small with track groove frictional ground force below rack, the mutual relative motion of the two controls driven gear by data command
It rotates, automatic demonstrating elastic ring drive process, structural stability is high, and service life is long.
In order to realize these purposes and further advantage according to the present invention, a kind of elastic ring transmission device is provided, including：
Rack-and-pinion linkage mechanism, with driven gear, rack and track groove, the driven tooth wheel and rack adaptation engagement,
The rack is slidably mounted in track groove；
Washer, for the elastic ring that shape arbitrarily changes, the washer is positioned in track groove, and pad is pushed down in the rack lower part
Circle；
Motor is used for as driven gear powered rotation, shaft and the electric machine main shaft linkage of the driven gear；
Host computer is used to generate motor power break-make and converts the control instruction of current direction in motor；
PLC is used to receive host computer motor power break-make and converts the control instruction of current direction in motor, and makes corresponding
Action, control motor power break-make and conversion motor in current direction；
Power supply provides electric energy for above-mentioned each electric elements.
Preferably, the washer is formed by connecting by a steel disc first place.
Preferably, washer is pressed into annular by the rack.
Preferably, the washer face is smooth.
Preferably, the electric machine main shaft drive connection driving gear, driving gear and the 3rd gear engaged transmission, the 3rd
Driven gear is installed in the shaft of gear.
Preferably, the motor is decelerating motor.
Preferably, the motor is decelerating motor.
The present invention includes at least following advantageous effect：Since host computer generates electric current in motor power break-make and conversion motor
The control instruction in direction, PLC receives host computer motor power break-make and converts the control instruction of current direction in motor, and makes
Current direction in corresponding action, control motor power break-make and conversion motor, therefore the data command intelligence for passing through host computer
Driven gear is controlled to rotate, structure novel, easy to operate, good demonstration effect meet prolonged Xun Huan demonstration；Due to washer by
One steel disc first place is formed by connecting, and washer is pressed into annular, therefore structure novel by rack, in mechanism operational process, below rack
Small with track groove frictional ground force, the mutual relative motion of the two will not damage rack by pressure.
Part is illustrated to embody by further advantage, target and the feature of the present invention by following, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
Description of the drawings
Fig. 1 is the overall structure diagram of elastic ring transmission device in the embodiment of the present invention；
Fig. 2 is the circuit diagram of elastic ring transmission device in the embodiment of the present invention；
Fig. 3 is the track groove internal structure exploded view of elastic ring transmission device in the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other elements or its combination.
Fig. 1 to 3 shows a kind of way of realization according to the present invention, including：Rack-and-pinion linkage mechanism 1, gear
Rack linkage mechanism 1 has driven gear 11, rack 12 and track groove 13, and the driven gear 11 is engaged with the adaptation of rack 12,
The rack 12 is slidably mounted in track groove 13, and washer 14 is the elastic ring that shape arbitrarily changes, and the washer 14 is positioned over
In track groove 13, washer 14 is pushed down in 12 lower part of rack, and motor is used to be 11 powered rotation of driven gear, described driven
The shaft of gear 11 links with 15 main shaft of motor, and host computer is used to generate motor power break-make and converts current direction in motor
