如何根据负载方向和传动方式确定滚珠丝杠选型参数？

题目：基于滚珠丝杠副的自动控制系统设计 摘要：本设计基于滚珠丝杠副，设计了一个自动控制系统。该系统主要由控制器、电机、滚珠丝杠副和传感器等组成。通过控制器对电机的控制，实现滚珠丝杠副的转动，进而控制传感器的信号输出。根据传感器信号，控制器可以对电机进行反馈控制，实现系统的自动控制。 关键词：滚珠丝杠副；自动控制系统；控制器；电机；传感器 Abstract: Based on the ball screw pair, this design proposes an automatic control system. The system mainly consists of a controller, a motor, a ball screw pair, and sensors. By controlling the motor through the controller, the rotation of the ball screw pair is realized, and the signal output of the sensor is controlled accordingly. According to the sensor signal, the controller can perform feedback control on the motor to achieve automatic control of the system.
