这个长度不建议用丝杆了,建议齿轮齿条

计算压杆稳定,加我qq

谢谢大佬 我的QQ690556539

百度一下,遇到具体问题再问。

我机械设计手册也查了,还做了表格,但是机械设计手册上面的计算方法不涉及长度,只是通过应力和施加的力计算出直径,昨天百度到十一点多,没有一个T型丝杆的校核介绍

gemiusunyi 发表于 2023-3-23 10:05:31

去论坛里搜机械计算,有个EXCEL的文档挺好用的
丝杆的传输好像时2Πx直径/螺距什么的,记得不太清楚
受力的这块应该是考虑直线导轨之类的去分担约束

先找找能加工5米长丝杆的厂子。

我的有效提升2m,丝杆部分只要2.5m,另外的可以焊接轴

找个TBI的设计手册看下。垂直放置的,龙门机床横梁升降。需要加导轨,辅助导向,抵抗扭矩。

轴向载荷 和丝杆的额定动载荷匹配,用齿轮齿条完美

Tr80x20(P10),5米,5吨没问题,保险系数3.4倍。材料40CrMo。

感谢大佬的指导,有没有指导一个丝杆拉力5吨,然后指导丝杆的导程0.016,丝杆的长度5m,然后反过来计算丝杆的直径最少是多少的过程呢

我猜你想要的不是丝杠计算,而是轴的承重会不会变形的问题。data:image/png;base64,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
