The screw lifter is composed of worm gear, worm, screw and nut and other main parts. It is a linear motion equipment.
Because there is a certain gap between the fitting of various parts, this characteristic determines that the screw rod will have a slight shaking amount, but this amount is not large, so the screw rod elevator can only provide the output in linear direction, and the stability needs to be supported by the additional guide device, which can be light column or guide rail. It can be reasonably designed according to its own equipment space.
Drive screw elevator, screw elevator, worm and worm elevator, precision quality, both appearance and processing technology are relatively advanced.
Some customers will ask whether it is possible to make the matching between each part seamless and ensure that the screw rod does not shake at all. The answer is impossible. Most mechanical equipment is like this. There is a gap between any two parts. The friction force in the movement without gap is unimaginable and it is difficult to drive.
