Question:
Why square threads are preferred over V-thread for power transmission ?
Answer:
. Square threads are preferred over V-thread for power transmission because of following points. 1) Square thread has the greatest efficiency as its profile angle is zero. 2) It produces minimum bursting pressure on the nut. 3) It has more transmission efficiency due to less friction. 4) It transmits power without any side thrust in either direction. 5) It is more smooth and noiseless operation.
