Abstract
The present invention provides a kind of pulsed arc-shaped rack external tooth gear structure, it is characterized in that, including rack, gear and can provide circumference rotation drive device, the rack is arc-shaped rack, the rack arc shaped inside sets tooth, the gear is external gear, and the rack and pinion engagement, the rack is connected with drive mechanism.During operation, driving rack is moved in a circle, and is engaged with linkage gear, drives gear movement, and then wheel and rack is separated, gear stop motion, and driving rack is engaged with linkage gear again after running one week, so as to form impulse movement.
Description
Technical field
The present invention relates to a kind of gear ＆ rack structure, and in particular to a kind of pulsed arc-shaped rack external tooth gear structure.
Background technology
Gear (Gear) is the colyliform machine components of the engagement transmission moment of torsion by tooth.It is mechanical with other dentations that gear passes through
Part（Such as another gear, rack, worm screw）Transmission, can be achieved to change rotating speed and moment of torsion, change the direction of motion and change motion shape
The functions such as formula.Due to transmission efficiency, gearratio is accurate, power bracket is big the advantages of, gear mechanism in industrial products extensively
Using it designs the quality that industrial products are directly influenced with manufacture level.Gear tooth mutually clasp gear can drive it is another
Individual pinion rotation transmits power.Two gears are separated, the gear on both sides can also be driven using chain, crawler belt, belt
And transmit power.
Conventional pulsed mechanical movement is moved back and forth frequently with crank connecting link, oil cylinder or rack and completed.Its mechanical structure phase
To complexity, part is more.Therefore a kind of more pulsed mechanical motion mechanism easy to use is needed.
The content of the invention
To solve above-mentioned problem, it is an object of the invention to provide a kind of pulsed arc-shaped rack external tooth gear knot
Structure, its is simple in construction, by using cooperatively for arc-shaped rack and gear, and circular motion can be converted into pulsed motion, tool
There is wide applicability.
To reach above-mentioned purpose, the technical scheme is that：
A kind of pulsed arc-shaped rack external tooth gear structure, it is characterised in that including rack, gear and can provide circumference rotation
Drive device, the rack is arc-shaped rack, and the rack arc shaped inside sets tooth, and the gear is external gear, the rack
Engaged with gear, the rack is connected with drive mechanism.During operation, rack moves in a circle, and is engaged with gear, band moving gear fortune
Dynamic, then wheel and rack is separated, gear stop motion, and rack is engaged with gear again after running one week, so as to form pulse
Motion.
As the further improvement of such scheme, the gear is provided with cushion hole.
As the further improvement of such scheme, the rack is provided with ring-like supporting construction.Operation hour rack and gear member
Impact is relatively strong and frequent, and the setting can alleviate impulsive force to a certain degree.
As the further improvement of such scheme, the gear, rack are made of alloy material.
Compared with prior art, the beneficial effects of the present invention are：
Its is simple in construction, by using cooperatively for arc-shaped rack and gear, and circular motion can be converted into pulsed motion, tool
There is wide applicability.
Brief description of the drawings
A kind of pulsed arc-shaped rack external tooth gear structural representation that Fig. 1 is provided by the embodiment of the present invention.
Wherein：
1st, rack；2nd, gear；3rd, cushion hole；4th, supporting construction.
Embodiment
The specific effect of the design of the invention, concrete structure and generation is entered below with reference to embodiment and accompanying drawing
Row is removed, complete description, sufficiently to understand the purpose, feature and effect of the invention.Every skill of the invention
Art feature, can be with combination of interactions in the premise of not conflicting conflict.
Referring to Fig. 1, a kind of pulsed arc-shaped rack external tooth gear structure, it is characterised in that including rack 1, gear 2 and energy
The drive device of circumference rotation is enough provided, the rack 1 is arc-shaped rack, and the arc shaped inside of rack 1 sets tooth, the gear 2
For external gear, the rack 1 is engaged with gear 2, and the rack 1 is connected with drive mechanism.During operation, rack 1 moves in a circle,
Engaged with gear 2, band moving gear 2 is moved, and then gear 2 is separated with rack 1, the stop motion of gear 2, after rack 1 is run one week
Engaged again with gear 2, so as to form impulse movement.
As the further improvement of such scheme, the gear 2 is provided with cushion hole 3.
As the further improvement of such scheme, the rack 1 is provided with ring-like supporting construction 4.Operation hour rack 1 and gear
2 impacts are relatively strong and frequent, and the setting can alleviate impulsive force to a certain degree.
As the further improvement of such scheme, the gear 2, rack 1 are made of alloy material.
It should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted.Although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to the technology of invention
Scheme is modified or equivalent substitution, and without departing from the scope of technical solution of the present invention, it all should cover the power in the present invention
In sharp claimed range.
