Abstract
The utility model relates to a pin and gear transmission combined rigid dummy bar which is composed of a dummy body, a needle-shaped gear and a transmission mechanism. The utility model is characterized in that the dummy body is changed from the original segment integral type to the segment combined structure, and the needle-shaped gear is arranged on a shaft of the transmission mechanism. The utility model has the advantages of novel structure and simple and reasonable structure and can adapt to the requirement of the adverse environment. The manufacture cost of the dummy body can be lowered and used, and the utility model is convenient in use, maintain and overhaul, can enhance the service life of the dummy rod and is an ideal pin and gear transmission combined rigid dummy bar.
Description
The utility model relates to drawing of a kind of steel plant continuous casting machine and decides device, and the rigidity of using on specifically a kind of conticaster is drawn and decided bar.
At present, the rigidity that billet caster uses in the metallurgical steelmaking equipment is drawn and is decided bar, forging base, camber processing, the outer arc mill teeths of adopting form more, draw the reciprocating motion of deciding bar and be by gear being housed on the gear train shaft and drawing fixed arc racks engagement on one's body and satisfy and draw the motion requirement of deciding bar, this structure of deciding bar of drawing has the following disadvantages: it is fixed as forged steel camber structure 1) to draw, outer arc has tooth bar, the processing and manufacturing difficulty, and cost is with high costs.2) it is higher to draw the engagement dimension precision requirement of the outer arc rack and pinion of deciding body, in hot environment, use and the effect of straightening machine under draw that to decide body yielding, thereby cause outer arc rack and pinion engagement inequality, increased fault rate, maintenance difficult, service life is low.
The purpose of this utility model provides the box-like rigidity of a kind of pin tooth transmission group draws and decides bar, thisly draws that to decide bar simple in structure, cheap, maintenance easily, and long service life is drawn the deficiency of deciding device in order to overcome existing usefulness.
The purpose of this utility model can realize by following embodiment:
The utility model is decided body, aciculiform gear and transmission mechanism and is formed by drawing, draw and decide body and change sectionally assembled structure into by former segmentation monoblock type, that is: every section is drawn with two that to decide body arc plate be parent, with the bearing pin of several same sizes two are drawn and to decide body arc plate and connect and combine, form ladder shape section, draw to decide to have on the figure to draw and decide head, then will be every segments combined drawing decides body and takes riveting and constitute to draw together and decide body, draws the transmission of deciding body and makes pin type into by outer arc rack.The improved kind of drive of deciding body of drawing has become the transmission that cooperates that aciculiform gear and ladder shape combined type draw fixed bearing pin on one's body by the rack-and-pinion transmission, be that the gear of installing on the gear train shaft that is mated has become the aciculiform gear accordingly, transmission mechanism also is original driver.
Advantage of the present utility model is a novel structure, simple, reasonable, the needs that can adapt to adverse circumstances draw the manufacturing cost of deciding body and can reduce greatly, and it is convenient to use, safeguard, overhaul, can improve and draw the service life of deciding bar, be that a kind of desirable box-like rigidity of pin tooth transmission group is drawn and decided bar.
To be described in further detail the utility model to closing accompanying drawing below.
Fig. 1 is an overall structure schematic diagram of the present utility model
Fig. 2 is a partial left side view
As shown in Figure 1, 2, originally draw and decide bar and decide body 4, aciculiform gear 3 and transmission mechanism 2 and form by drawing, draw and decide body 4 and change sectionally assembled structure into by former segmentation monoblock type, that is: every section is drawn with two and to decide body arc plate 5 and be parent, with the bearing pin 6 of several same sizes two are drawn and to decide body arc plate 5 and connect to combine and form ladder shape section, draw to decide to have on the figure and draw fixed 1, then will be every segments combined drawing decides body and takes riveting and constitute to draw together and decide body, draws the transmission of deciding body and makes to be the pin type transmission into by outer arc rack shape.The improved kind of drive of deciding body of drawing has become aciculiform gear 3 by the rack-and-pinion transmission and has drawn the transmission that cooperates of deciding body bearing pin 6 with ladder shape combined type, be that 2 gears that are mated of going up installation of transmission mechanism have become aciculiform gear 3 accordingly, transmission mechanism 2 also is original transmission mechanism.
All parts of the utility model are steelwork.
Claims (3)
1, the box-like rigidity of a kind of pin tooth transmission group is drawn and is decided bar, decide body (4) by drawing, aciculiform gear (3) and transmission mechanism (2) are formed, it is characterized in that drawing and decide body (4) for sectionally assembled structure, be every section and draw with two that to decide body arc plate (5) be parent, with the bearing pin (6) of several same sizes two are drawn and to decide body arc plate (5) and connect and combine, form ladder shape section, draw to decide to have on the figure and draw fixed head (1), then will be every segments combined drawing decides body and takes riveting and constitute to draw together and decide body (4), drawing the transmission of deciding body (4) is the pin type transmission, is the transmission that cooperates that aciculiform gear (3) and ladder shape combined type draw fixed bearing pin (6) on one's body.
2, according to claim 1 drawing decided bar, and what it is characterized in that on transmission mechanism (2) axle installing is aciculiform gear (3).
3, according to claim 1 and 2 drawing decided bar, it is characterized in that it is steelwork.
