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 adequatelydecreased; 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 radiusR2of 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 divisi on 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 processedaccording 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 wheelmachine.
Description
technical field [0001] The invention relates to a tooth plate of a star wheel in a sintering machine for smelting, and relates to a method for modifying the tooth shape of the tooth plate. Background technique [0002] The trolley loaded with sintered materials is driven by the star gear plates at both ends of the track of the sintering machine to make the trolley run in a cycle. It is realized by turning the card wheel on the trolley through the star gear plate. When the trolley runs to the tail end and enters the return lane, the rear wheels are easily lifted, which is called arching. In severe cases, the height of the arching can reach more than 20mm. The harm caused by this arching phenomenon is: accelerated wear at both ends of the trolley, causing air leakage during the sintering process; increased load on the wheels and bearings of the trolley, affecting the service life; The arch will fall due to its own weight, causing an impact. This arching phenomenon has a lot ...
