screwjacks

The keyed screw jack usually means acme screw jack with anti-rotation function. Some loads are not allowed to rotate with the screw. These applications require a keyed screw jack. A key, fixed to the jack housing and inserted in a keyway milled into the lifting screw, forces the lifting screw to translate without rotating.

The lifting speed of the worm gear screw jack is limited.If the lifting speed is too fast, the friction heat and the wear are very strong, and the service life of the screw lift will be greatly discounted. The lifting speed depends on three factors: input speed, worm ratio, screw pitch. To increase the speed, you should 1.Use a 4pole motor to directly input, do not use 6pole motor or decelerate through the reducer and then input to the screw lift. 2.Choose fast speed ratio 3.Use a large pitch screw within the allowable range. Under normal circumstances, the screw is a single head, here we can make a double-headed screw according to the actual situation, so that the lifting speed can be doubled.

The upright screw jack is usually used to lift or push up objects(screw top end is up the mounting base). The inverted screw jack is usually used to lift or press down object(screw top end is below the mounting base).

Worm gear screw lifts are widely used, but at the same time, there are often some problems. For these problems arising from the worm gear screw lifts, Lude Transmission will organize and share solutions for everyone, and hope to be useful to everyone. What are the causes and treatments of the worm gear screw lift during normal use? The causes of the vibration of the screw lifter after the additional load during use are the uneven worm splitting, the uneven pitch of the lead screw, the over-tightening of the upper and lower sheaths of the lead screw, the flat pressure bearing and the quality of the tapered bearing, and the installation. Disagreement. Just check it and reinstall it according to the installation instructions. What are the reasons for the excessive temperature rise and the death of the screw lift and how to deal with it? The maximum temperature of the screw lifter under normal working conditions shall not exceed 45 degrees Celsius. If th

The worm gear screw jacks are widely used in our daily life, and we can see the use of screw jack in iron and steel enterprises or in machinery factories or in hardware factories.  So how do you use it better? First of all, when we use screw lifts, we need to know that the worm gear screw jacks are relatively fragile and afraid of water naturally, so if there is water dripping on the jack, you should dry it in time, or remember to install a blower when the screw jack is installed. Even if there is water, it can be cleaned in time. Secondly,when the screw jack is not used, what we need to do is to place the screw lifter in a cool and dry place. At this time, we need to do a lot of things. For example, in a certain period of time, we should promptly turn our screw lifts. At the same time, when the worm screw lift is placed, it can not be stacked, otherwise the lifespan of the screw lift will be shortened. Third, in the use of worm screw lifts , we sh
