升降缸用关节轴承钢包回转台属于连铸设备,它装有接受浇铸包的托叉形伸臂。根据回转台的结构,伸臂即可采用滚柱轴承和轴向球面滚柱轴承来支撑,也可以放在一个摆动的支承装置上。由于承受的力和扭矩很大,绝大部分都采用组合的轴向-径向-滚柱轴承作为摆动支承装置。但是,摆动臂不仅在接受浇铸包或者浇铸时要能在原位置摆动,而且在其高度方向也要能进行调节。这种高度方向上的提升可以采用液压缸驱动。在这种情况下,要用两个液压缸来支撑回转台,用活塞杆单独地将伸臂提升到所要求的高度,由于在提升过程中不能作平行的 Joint bearings for lifting cylinder ladle turntable belonging to the continuous casting equipment, which is equipped with a fork to withstand the casting package boom. Depending on the structure of the turntable, the boom can be supported by roller bearings and axial spherical roller bearings, or on a swinging support. Due to the large forces and torques, the combined axial-radial-roller bearings are used as oscillating support. However, the swing arm must be able to swing in the original position not only when receiving the casting bag or casting, but also in the height direction. This height-wise lift can be hydraulic cylinder driven. In this case, two hydraulic cylinders are used to support the turntable, the piston rod alone to raise the boom to the required height, due to the lifting process can not be parallel
