What is the difference between ball screw jack and trapezoidal screw jack?
What is the difference between ball screw jack and trapezoidal screw jack ? When to use ball screw jack , When to use trapezoidal screw jack ? Let’s look at the difference between ball screw jack and trapezoidal screw jack with these questions, and explain it roughly from the following 7 aspects. 1. Different structures. The movement principle of trapezoidal screw jack and ball screw jack is the same, but the difference is that there is no ball in trapezoidal screw, so the movement between nut and screw shaft depends entirely on mechanical contact to produce sliding 2. Different transmission efficiency. The transmission efficiency of most ball screws is as high as 90%, and some even reach more than 95%, while the transmission efficiency of most trapezoidal screws is lower than 70%. trapezoidal screw is not suitable for high-speed operation, and its maximum speed is generally not more than 3000RPM. And the ball screw, because it is rolling friction, does not g
