圈上泽支大峰 Example A square thread power screw has a major diameter of 32 mm and a pitch of 4 mm with double threads. Find the thread depth,thread width,mean or pitch diameter,minor diameter and lead. 圈上泽夫道大学 Example Solution: Thread depth p/2 =4/2 =2 mm Thread width p/2 =4/22 mm Mean(pitch)diameter=d-p/2=32-4/2 30 mm Minor diameter =d-p=32-4=28 mm Lead 2*p(double threads)=2*4=8 mm 1717 Example A square thread power screw has a major diameter of 32 mm and a pitch of 4 mm with double threads. Find the thread depth, thread width, mean or pitch diameter, minor diameter and lead. Thread depth = p/2 = 4/2 = 2 mm Thread width = p/2 = 4/2 = 2 mm Mean (pitch) diameter = d – p/2 = 32 – 4/2 = 30 mm Minor diameter = d – p = 32 – 4 = 28 mm Lead = 2*p (double threads) = 2*4 = 8 mm Solution: Example
