The answer is as follows: the structure of linear slide rail has four main accessories: linear guide rail, profile body, lead screw nut and motor.
His transmission principle is: the motor outputs power, which drives the screw rod to rotate through the coupling, and the screw rod rotates and is squeezed by the ball inside the nut. Because the nut is fixed with the slide seat and the guide rail, this means that the nut does linear reciprocating motion.
