軋機(jī)上使金屬產(chǎn)生連續(xù)塑性變形的主要工作部件和工具。軋輥主要由輥身、輥頸和軸頭3部分組成。輥身是實(shí)際參與軋制金屬的軋輥中間部分。它具有光滑的圓柱形或帶軋槽的表面。輥頸安裝在軸承中，并通過軸承座和壓下裝置把軋制力傳給機(jī)架。傳動(dòng)端軸頭通過連接軸與齒輪座相連，將電動(dòng)機(jī)的轉(zhuǎn)動(dòng)力矩傳遞給軋輥。軋輥在軋機(jī)機(jī)架中可呈二輥、三輥、四輥或多輥形式排列。

The main working components and tools on the mill that produce continuous plastic deformation of the metal. The roll is mainly composed of a roll body, a roll neck and a shaft head. The roll body is the middle part of the roll that actually participates in the rolling of the metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in the bearing and the rolling force is transmitted to the frame through the bearing housing and the pressing device. The transmission end shaft head is connected to the gear base through the connecting shaft, and transmits the rotational torque of the motor to the roller. The rolls can be arranged in the form of two rolls, three rolls, four rolls or multiple rolls in the rolling mill stand.
