 轧钢机减速器泛指完成轧材生产全过程的装备﹐包括有主要设备﹑辅助设备﹑起重运输设备和附属设备等。
根据用途和结构可分为330、350、380、400、420、450、475、500、560、620、750、800等多种规格的高速线材、棒材轧机减速机，包括水平轧机、立辊轧机、平立可换轧机减速机及配套的伞齿轮箱等，并且可以根据用户要求进行不同规格、不同结构的高速线材、棒材轧机减速机的设计与研制。
轧钢机专用减速器的工作特点是低速、重载，冲击负荷大，冲击次数频繁，而且是连续工作。随着我国轧钢工业的迅速发展，钢材品种的不断扩大，产量的增加，轧制速度的提高，轧制负荷增大，要求轧机齿轮传动装置具有足够的承载能力，即具有高强度、高精度、高寿命和高可靠度。因此，现代大中型轧机齿轮装置一般都采用经精加工的硬齿面和中硬齿面渐开线圆柱齿轮，并采用轮齿修形、深层渗碳、喷丸强化等设计制造技术。
Rolling mill gear reducer refers to the entire process of rolling production equipment, including the main equipment, auxiliary equipment, lifting and transportation equipment and ancillary equipment.
According to the purpose and structure can be divided into 330, 350, 380, 400, 420, 450, 475, 500, 560, 620, 750, 800, etc. Various specifications of the high speed wire rod and bar mill reducer, including horizontal mill, vertical mill, vertical mill reducer may be substituted, and form a complete set of bevel gear box, etc., and can according to user requirements for different specifications, different structure of high speed wire rod and bar rolling mill reducer design and development.
The working characteristics of the special reducer for rolling mill are low speed, heavy load, large impact load, frequent impact times and continuous work. With the rapid development of steel rolling industry in China, the continuous expansion of steel varieties, the increase of output, the improvement of rolling speed and the increase of rolling load require the mill gear transmission device to have enough bearing capacity, that is, high strength, high precision, high life and high reliability. Therefore, the gear device of modern large and medium-sized rolling mill generally adopts the precision-machined hard tooth surface and the involute cylindrical gear of middle and hard tooth surface, and adopts the design and manufacture technology of gear modification, deep carburizing, shot peening and so on. |
