在研制高效而又可靠的采煤机时,拟定用小尺寸机械传动装置向截割和牵引部工作机构传递大力矩的新结构方案是一项迫切的任务。苏联制造的采煤机广泛使用的、基于多级齿轮传动的传统式单(能量)流传动系统,不可能使机械传动适应预定的尺寸,因为该预定尺寸受到回采工艺及采煤机与综采配套职能机械协调条件的限制。因此,必须认真研究采煤机单个部件结构的功能,部分地将机械传动从截割部主减速器直接地移到工作机构中,在重载机械传动中采用多行星轮的行星齿轮传动的多(能量)流传动结构。
In the development of efficient and reliable shearers, it is an urgent task to develop a new structural solution that uses a small-sized mechanical transmission to transmit large moments to the cutting and pulling mechanism. It is not possible to adapt the mechanical transmission to a predetermined size, which is widely used by Soviet-type shearers and based on a conventional single (energy) flow drive system based on multi-stage gearing, since the predetermined size is affected by the recovery process and the shearer and the fully mechanized Supporting functions Mechanical coordination conditions. Therefore, the function of the single-part structure of the shearer must be carefully studied, the mechanical transmission is partially moved directly from the final reducer of the cutting section into the working mechanism, and the number of planetary gears driven by the multi-planetary gear in the heavy-duty mechanical transmission is large (Energy) flow drive structure.
