| 摘 要： | 针对高速机床滚珠丝杠的摩擦发热导致丝杠产生轴向热伸长的问题,采用丝杠和螺母中空冷却的方法抑制丝杠温升,通过不同进给速度下的实心滚珠丝杠与空心滚珠丝杠的稳态仿真对比,证实这种冷却方法有效;同时对比瞬态仿真得出空心滚珠丝杠达到热平衡的时间远小于实心滚珠丝杠。

Research on Thermal Characteristic of Solid/Hollow High speed Ball Screw |

| Abstract: | Aiming at the problem that high?speed machine tool ball screw friction heat caused thermal elongation in axial direc?tion, the hollow cooling method was adopted for the ball screw and nuts to restrain the temperature rising of screw. Through steady state simulation compare between the solid ball screw and the hollow ball screw under different feeding speed, the cooling method was con?firmed to be effective, and hollow ball screw reaching thermal equilibrium time is far less than that of the solid ball screw through the transient simulation. |
