Abstract
The invention discloses a correction method for a star wheel toothed plate curve and a star wheel toothed arc curve, wherein, on the basis of the prior star wheel toothed plate with three pitch diameters, diameters of three concentric circles of a division circle, a pitch circle and a clamping wheel circle are not changed; the diameter 1 of an excircle on the star wheel toothed plate is adequately decreased; an auxiliary circle the diameter 2 of which is smaller than that of the pitch circle is produced; the radius R1 of the toothed arc curve is adequately decreased and the radius R2 of the toothed arc curve is adequately increased; the radius r1 of a transition curve is adequately decreased and the radius r2 of the transition curve is adequately increased; the circle center of the radius R2 of the toothed arc curve is arranged on the auxiliary circle and the circle center of the radius R1 of the toothed arc curve is arranged on the connecting line of the intersection point of the division circle and the toothed plate curve and the circle center of the R2 of the toothed arc curve. Compared with the prior star wheel toothed plate, the star wheel toothed plate corrected and processed according to the invention looks small and the arc camber phenomenon of a loop wheel machine is obviously reduced when the star wheel toothed plate is arranged on the operating tail of the loop wheel machine.
Description
Technical field
The present invention relates to smelt the star wheel toothed plate with in the sintering machine, is a kind of method for correcting of tooth plate profile of tooth.
Background technique
Loading is sintered the chassis of material, relies on the star wheel toothed plate transmission at sintering machine track two ends, makes chassis do circular flow, and it is to stir card on the chassis by star wheel toothed plate to take turns and realize.After chassis moves to the afterbody discharging, enter loop, trailing wheel very easily lifts, and is called arch camber, and when serious, springing height reaches more than the 20mm.This arching phenomenon, the harm that causes is: quicken the wearing and tearing at chassis two ends, cause leaking out of sintering process; Bogie wheels and bearing load thereof increase, and influence working life; When chassis moved near head, chassis arch camber meeting was fallen because of the deadweight effect, causes impact.This arching phenomenon has much relations with the sector curve of star wheel toothed plate.Existing sintering machine has the star wheel toothed plate of three kinds of different sizes, the pitch diameter of three kinds of star wheel toothed plate is: φ 4136, φ 3098.52, φ 2775.5 (mm), profile of tooth on the star wheel toothed plate is the cylindrical of Φ 1 by diameter, sector curve (comprising that radius is respectively the curve of R1 and R2), tooth root portion circular arc line and radius are r1, the transition curve of r2 is formed, cross the circle that radius is respectively two intersections of complex curve of R1 and R2 and be boundary circle, the boundary diameter of a circle be on the star wheel toothed plate outside diameter Φ 1 1/1.11, the circle of crossing the card wheel center of circle is card circle, pitch circle, the boundary circle, card wheel circle is three concentric circles.The characteristics of star wheel toothed plate are: outside diameter Φ 1 is bigger, and three kinds of outside diameter Φ 1 are respectively 4756,3476,3175 (mm); The center of circle of sweep R2 is on pitch circle; Sweep R1 is bigger, and three kinds of sweep R1 are respectively 250,140,140 (mm), and R2 is smaller, and three kinds of sweep R2 are respectively 510,310,340 (mm); Transition curve radius r 1 is bigger, and three kinds of transition curve radius r 1 are 120 (mm), and r2 is smaller, and three kinds of transition curve radius r 2 are respectively 50,30,5 (mm).Therefore, star wheel toothed plate is relatively looser, and transition curve radius r 2 is smaller, is the main cause that causes the chassis arch camber.
Summary of the invention
Purpose of the present invention is the method for correcting that a kind of star wheel dental plate rack circle curve is provided for the problem that solves above-mentioned prior art existence.Star wheel toothed plate by this method corrected parameter processing is installed on chassis operation afterbody, can obviously reduce the chassis arching phenomenon.
The inventive method is achieved in that the star wheel toothed plate by existing pitch diameter, keeps boundary circle, pitch circle, round three the concentrically ringed diameters of card wheel constant, and the outside diameter Φ 1 on the star wheel toothed plate is reduced 20～40mm; Make the auxiliary circle of a diameter of phi 2 less than pitch diameter 20～80mm; To reduce 20～50mm at the first sector sweep R1 between cylindrical on the star wheel toothed plate and the boundary circle respectively then, the second sector sweep R2 between pitch circle and boundary circle strengthens 50～100mm; To be positioned at respectively that the transition curve radius r 1 of tooth root portion circular arc line and the second sector curve intersection place reduces 10～40mm on the star wheel toothed plate, the transition curve radius r 2 at the star wheel toothed plate cylindrical and the first sector curve intersection place strengthens 20～100mm; The center of circle of the second sector sweep R2 is positioned on the auxiliary circle, and the center of circle of the first sector sweep R1 is positioned on the line in the center of circle of the intersection point of boundary circle and first, second sector curve and the second sector sweep R2.
The present invention is to the tail star gear tooth plate, the method for correcting of the sector curve of revising according to its pitch diameter.Star wheel toothed plate by the processing of the inventive method corrected parameter is compared the slight of stature that seems with existing star wheel toothed plate, transition curve radius r 2 strengthens, and is installed on chassis operation afterbody, has obviously reduced the chassis arching phenomenon.Through practicality, springing height is reduced to about 5mm, and the continuous correction by to above-mentioned parameter is expected to finally eliminate arch camber.
