滚珠丝杠的最大载荷可以根据以下公式来计算: Fmax = (π/4) x D^2 x σb x 10^-3 其中,Fmax表示最大载荷,D表示滚珠丝杠的直径,σb表示滚珠丝杠的材料抗拉强度。 需要注意的是,这个公式仅适用于螺旋角为0度的滚珠丝杠。如果螺旋角不为0度,则需要使用其他公式来计算最大载荷。此外,还要考虑到滚珠丝杠的工作环境、运动速度等因素,以确保滚珠丝杠的安全可靠运行。
因此,在选择PMI或滚珠丝杠时,应根据具体应用场景和要求进行选择,以满足所需的精度、速度、负载能力、可靠性等要求,它采用滚珠丝杠作为升降机构,具有精度高、噪音低、载重能力强、寿命长等特点,广泛应用于工业生产、仓储物流、商业物流、医疗卫生等领域,陕西自动化仪器有限公司坚持以客户需求为导向,持续改进产品和服务质量,不断提升客户满意度,
2. SBR系列:SBR16、SBR20、SBR25、SBR30、SBR35、SBR40等,在实际应用中,速比一般是通过滚珠丝杠的螺距和螺母的导程来确定的,Precision ball screw production overseas
