5. 安装好轴承后，应检查轴承是否安装正确，是否有过紧或过松等情况,该机构采用滚珠丝杠传动，具有稳定性高、噪音小、寿命长等特点,滚珠丝杠主要应用于高精度直线运动、转动运动和旋转运动的传动，电动滑台则主要应用于平面上的线性运动, 4. P3级：误差在±3μm以内,一般来说，卷板机使用的滚珠丝杠应具有高精度、高速度、高刚度、高负载能力、低摩擦、低噪音等特点，以确保卷板机的稳定性和精度, 根据以上参数可以确定滚珠丝杠的规格,滚珠丝杠副的制动方式有以下几种： 1. 机械制动：通过机械装置使滚珠丝杠副的导轨或轴承停止转动，从而实现制动, 关键词：滚珠丝杠；升降机；传动效率；负载能力；动态响应 Abstract: This paper mainly introduces the structure and working principle of the ball screw lifting mechanism, and analyzes and evaluates its performance. Firstly, the basic principle and classification of the lifting machine are introduced, and then the structure and working principle of the ball screw lifting mechanism are introduced in detail, including the ball screw, guide rail, motor and other components. Then, the performance of the ball screw lifting mechanism is analyzed and evaluated, mainly including transmission efficiency, load capacity, dynamic response and other aspects. Finally, the advantages and disadvantages of the ball screw lifting mechanism are discussed, and some improvement measures and application prospects are put forward. Keywords: ball screw; lifting machine; transmission efficiency; load capacity; dynamic response, 4. 滚珠加工：滚珠丝杠需要滚珠来滑动，因此需要在丝杠上开凿滚珠槽,青岛滚珠丝杠升降机构是一种能够实现垂直运输的机构，由电机、减速器、滚珠丝杠、导轨、控制系统等组成
