Description
Technical field
The present invention relates to the metallurgical machinery equipment field, particularly relate to a kind of continuous pallettype sintering machine head-tail star gear flute profile.
Background technique
At present the number of teeth of the continuous pallettype sintering machine head-tail star gear of using in the actual production is an odd number, is generally 17 teeth or is 19 teeth; Tooth curve or obtain by geometrograph according to external product perhaps obtains by the tooth curve of sprocket wheel is approximate; Pitch equals the draw gap of the wheelspan of chassis with assurance chassis and chassis row, thereby guarantees the normal circulation running of chassis row.
Meshing relation between continuous pallettype sintering machine star-wheel and the chassis is gear-pin rack engagement, therefore above-mentioned approximate flute profile has brought defective for the main transmission of continuous pallettype sintering machine, show that mainly chassis is listed in the fluctuation that occurs speed in the movement process, profile wear is serious, is the one of the main reasons of sintering machine chassis arch camber in operation process.
Though the star-wheel tooth curve can be implemented theoretically by the involute design, consider the transport characteristics and the transmission accuracy of continuous pallettype sintering machine, the application in practice of this method is the comparison difficulty.External for example Japanese scholar is designed to chassis width greater than 1/2 with the chassis wheelspan, and the star-wheel pitch that is engaged with equals the chassis wheelspan, relies on this " off-centre " to produce like this and draws gap, thereby makes continuous pallettype sintering machine can not have the operation of interference.Continuous pallettype sintering machine in producing at present all designs with the method, but the drawback of this method is conspicuous in producing at present, and it is not classic design.
(patent No.: 88104846.1) disclosed is a kind of new-type head and tail spiders for sintering machine to Chinese patent " new-type head and tail spiders for sintering machine ", and this star-wheel is long tooth and short tooth nonstandard gear alternately, and the number of teeth is an even number; New-type head and tail spiders can make chassis row uniform motion, and the pressure angle that meshes between star-wheel and the chassis is 0 degree, and star-wheel is the card wheel before the short-and-medium tooth of running promotes, and long tooth promotes back card wheel.This patent is the star-wheel flute profile that obtains from static analysis, also needs to do further improvement in actual applications.
Summary of the invention
Be in operation in order to overcome existing continuous pallettype sintering machine head-tail star gear that speed fluctuation, profile wear to occur serious and cause problem such as chassis row arch camber, the invention provides a kind of continuous pallettype sintering machine new tooth head-tail star gear, this invention has gone out the traitorous determinative star wheel that the facewidth does not wait according to the concrete structure size design of chassis, the theory of engagement of gear-pin gear transmission can be satisfied, drawing seam and catching up with motion of chassis row can be realized again.
The technical solution adopted for the present invention to solve the technical problems is: this continuous pallettype sintering machine new tooth head-tail star gear is made up of star-wheel body 10 and duplex tooth plate 9, star-wheel is the even number tooth, the number of teeth is 16-20, the effect of star-wheel body 10 is that duplex tooth plate 9 is fixed in correct position, thereby parameters such as the pitch diameter of assurance star-wheel, pitch adhere to specification; Duplex tooth plate 9 is tooth curve, pitch diameter, the isoparametric direct carrier of pitch, it is key point of the present invention, it directly provides the motion of chassis row needed power, different according to the facewidth with function, be divided into two kinds in wide tooth and narrow tooth, the be meshed tooth curve of face of two kinds of teeth and chassis card wheel is identical, form by rounding I, involute, rounding II, acceleration curve, two kinds of back of tooth equally also are made up of rounding I, involute, rounding II, acceleration curve from the tooth curve that is meshed with chassis card wheel; In order to guarantee that star-wheel and chassis card wheel breaks away from smoothly engagement, it is different with radius and the Surface of action of rounding I between the top circle: the rounding I radius of engagement side is generally got 8-12mm, and non-engagement side rounding I radius equals the chassis card and takes turns radius, wherein:
The involute parametric equation is:
x＝Rcos-Rsin
y＝Rsin+Rcos
The acceleration curve parametric equation is:
More than in two formulas
X, y---the point coordinates on the curve
---parameter
d
r---chassis card wheel radius
R---star-wheel Pitch radius
δ---draw gap
Z---the number of teeth
Non-engagement side also is made up of these four sections curves, different the is radius of rounding I between involute and the top circle and gradually open and acceleration curve between the radius of rounding II all equal card wheel radius.
During star-wheel work, the effect of acceleration curve is the motion of catching up with that guarantees that chassis is turned and drawn the generation of seam and realize single chassis, and the effect of involute is to guarantee that the chassis row can not produce inertia impact by uniform motion.These two kinds of curves are merged the title tooth curve, and the junction connects by rounding II, and rounding II radius equals card wheel radius, to guarantee the tangent relation of transition position.During merging, acceleration curve is near the tooth root place, and involute is near the tooth top place.
The invention has the beneficial effects as follows: this continuous pallettype sintering machine new tooth head-tail star gear, its tooth curve greatly reduce the chassis impact and the wearing and tearing in when running row, have further controlled and eliminated the problem of continuous pallettype sintering machine leave from office car team arch camber; While all has important and practical meanings for the prolongation of the part life of sintering machine, the minimizing of energy consumption.

Tooth curve is formed by three sections, adds man-hour the tooth curve on the duplex tooth plate to be comprised the rounding discretization, forms 319 key points, and the coordinate center of circle is at the circle centre position of the middle roller seating space circle of duplex tooth plate shown in Figure 2.Point 1 (466.2006 ,-174.9728), point 2 (459.0687 ,-171.8556) ..., point 318 (447.9599 ,-167.8982), point 319 (455.1183 ,-170.9528).These points have comprised the full detail of tooth curve, and it is gone into numerical control machine tool, carry out the actual motion precision needs that the wide type of processing that interpolation operation obtains can satisfy the sintering machine star-wheel well by numerical control machine tool, and then full wafer duplex tooth plate is processed.
In order to guarantee minute of angle and the radially fitted position of duplex tooth plate 9 on star-wheel body 10 circumference, the two adopts articulation hole to connect, and this joining method also can be expired the requirement of linking intensity well simultaneously.
Star-wheel of the present invention also has the rotation direction requirement.
Chassis is made up of two pairs of card wheels, star-wheel of the present invention is when meshing with chassis, have definite engaging position: wide tooth must participate in engagement between two pairs of card wheels of chassis, narrow tooth participates in engagement between the card wheel of two adjacent chassis, thereby making single chassis quicken to produce draws seam and catches up with chassis row uniform motion.
Chassis need draw seam to produce the gap through bend end to end the time, and the gap that draws originally relies on card
The wheel wheelFrom (be b＞l/2), and the star-wheel pitch that is meshed with the card wheel equaling card and takes turns wheelspan b greater than 1/2nd of chassis width.Therefore when entering engagement and breaking away from match, chassis is listed in the engagement place seam is drawn in generation.The gap that draws with sintering machine of novel dental star wheel has the star-wheel tooth curve to guarantee that transmission meets the theory of engagement, operates steadily.
