Screw lift structure after the election finished, you can choose whether to add an anti-rotation, the main feature is the anti-rotation preventing screw rotation during operation, since the worm comes friction in the rotation when the worm will lead wire swl5 screw lift rod rotation, if rotating screw screw rise or fall will not achieve the effect, so do not be fixed if you screw it, is the need to increase the anti-rotation. Next, choose a power source screw lift, you need to bring the motor, or with a hand wheel or drive shaft coupling with other devices, depending on the circumstances. Then select the ratio, ratio is really important, the size ratio, determines the speed of your movements, and motor selection. The next step is to choose the screw jack screw connection part tp screw lift, also known as the screw head swlii screw lift, under normal circumstances, there are several to choose from this, screw type, skinhead type (general way to screw the nut does not move up and down movement), flange type (which is most commonly used), hinged type, and so on. Preferably, after these parameters are selected, and then determine whether you need to increase, screw protective steel (hard), screw dust cover (soft), whether with limit switches and so on.
