摘 要:在轧钢生产线上,推钢机是将钢坯推进加热炉进行加热的专用炉前辅助加热设备,实现对钢坯进行二次加热的过程。推钢机输出动力,逐步向炉内推移,进行加热处理。推钢机的种类很多,本次设计选用齿条式双排推钢机,它通过齿轮齿条的啮合传动,将电机的旋转变换为齿条的直线运动,从而带动推杆进行推钢动作。其工作稳定可靠,传动效率较高,推力和行程大。根据推钢机120t推力的要求,合理设计推钢机的结构并进行传动方案的详细设计,最终设计出满足棒材厂120t推钢机电动机的选用、传动方式和装置的设计、减速器的选用、主要轴系零件的设计,并对传动机构和关键轴进行强度和刚度的校核。

ABSTRACT:With the continuous development of hydraulic technology and production of steel rolling technology, the new type hydraulic push steel machine gradually replaced the old mechanical push steel machine, although machine mechanical push steel is big volume, high price, large power consumption, the thrust is very big, and has good adaptability to temperature; it saves workshop and construction cost because of separating configuration hydraulic station; it use mechanical power source to replace hydraulic power source, furnace man to make safer, and still has an irreplaceable role.

   In steel rolling production line, steel machine is a special billet pushing reheating furnace for heating furnace before the auxiliary heating device to realize the process of secondary heating of steel billets. By pushing steel machine output power, and gradually entering the furnace and heating steel . There are many different kinds of steel mill, such as rack type, crank connecting rod type, hydraulic type, spiral, and hydraulic rack type, etc., each has its characteristics. Rack type push steel machine drives the push rod to push the steel through the meshing of gear and rack and driving motor of the rotation movement into the linear motion of the rack. Its working safely and reliable, high transmission efficiency, thrust and stroke.
