英语翻译
1.The screw diameter ranges from 6 to 100 mm,whereas the screw leaddoes it between 1 and 60 mm,keeping a certain proportionality between these two features.
2.If the lead is high,fast movements can be obtained but with a low mechanical advantage.Small leads imply slow movements but with a high mechanical advantage; at the same time small ones are more highly recommended to ensureprecision and controllability of the drive train.
第一段我知道意思,为了让大家理解前后意思放上来了,第二段我完全没看懂,
1.螺纹直径范围为6-100毫米,但是螺距在1-60毫米之间,在这两种特性之间保持一种平衡.
2.如果螺距大的话,可以获得快速运动,但是机械效益较低.小螺距意味着低速运动,但可获得较高的机械效益;同时,多数推荐采用小螺距以确保驱动系统的精度和可操控性.
