摘要
滚珠丝杠的温升直接影响其使用的精度,通过误差补偿技术可以解决这一问题,为了研究预紧力作用下丝杠的温升情况,通过摩擦生热和热对流原理建立了计算滚珠丝杠副温升的理论模型,探究了丝杠温升与预紧力的关系。将通过该模型计算的不同预紧力下的理论温升,与试验测得的试验温升进行对比分析,试验结果证实了该计算模型的正确性。该模型对于滚珠丝杠在使用中的热变形误差补偿具有十分重要的意义。
The temperature rise of the ball screw directly affects the accuracy. Error compensation can solve this problem effectively. In order to study the temperature rise of ball screw under the pre-tightening force,a theoretical calculation of ball screw temperature rise was established based on the principle of friction heat and heat convection. The temperature rises under different pre-tightening forces were calculated,and the results were compared with the experimental results. Through these works,the calculation was proved to be correct and is very important for the error compensation of ball screw.
