轧制滚珠丝杠的使用条件包括以下几个方面:
1. 温度:轧制滚珠丝杠的使用温度范围一般为-25℃~+100℃,
4. 滚珠丝杠的牙形一般要求高精度,特别是在高速运动的情况下,要求更高的精度,
2. 在Part Design工作台中,创建一个圆柱体作为丝杠的母体,一般来说,电机的转速、扭矩、功率、效率、噪音、振动等指标是评价电机质量的重要指标,
综上所述,电机带动滚珠丝杠的计算公式为:
所需功率 = (负载扭矩 × 转速)/ 9550
其中,负载扭矩为滚珠丝杠所需的扭矩,单位为N·m;转速为滚珠丝杠所需的转速,单位为rpm;9550为转换系数,
Abstract:
This paper introduces a design scheme of ball screw lift. The lift is mainly composed of motor, ball screw, transmission shaft, guide rail and platform. Through the analysis of the kinematic principle of the lift, the parameters such as the power and speed of the motor, the specification of the ball screw, the material and size of the guide rail are determined. At the same time, the safety and stability of the lift are analyzed and optimized, ensuring the safety and stability of the lift. Finally, SolidWorks software is used for three-dimensional modeling and dynamic simulation analysis to verify the feasibility and superiority of the lift design.
Keywords: ball screw, lift, kinematics, safety, stability, three-dimensional modeling, dynamic simulation analysis.,
2. 高速度:由于滚珠丝杠的滚珠可以减少摩擦力,因此可以实现高速旋转和移动,拆卸时需要注意,避免损坏机床零部件,
总的来说,选择滚珠丝杠的精度需要根据具体的应用场景和需求来确定,不能一概而论,
3. SFU2505:直径为25mm,螺距为5mm的滚珠丝杠,适用于大型数控车床和加工中心
