Worm shafts and their uses

Worm shafts have several advantages over standard gears. The worm is much smaller and can be placed anywhere on the gear. It can be used in many applications and requires less maintenance than standard gears. However, it is not suitable for heavy-duty applications as it is prone to wear and results in reduced motor efficiency. Therefore, worm shafts with high lubrication requirements should be avoided.

Worm shafts are usually made using worm gears, which provide high-speed gear reduction and fine adjustment. These gears do not move when the power is off. Therefore, they are very suitable for various applications. You can also choose from standard sizes or custom-designed assist systems. For more information, please contact the manufacturer in your area or download our free brochure. After reading this article, you will have a better understanding of worm shafts and their uses.

When designing a worm gear, you should consider many different factors. One of them is the size factor. This is important when choosing a worm gear, as a smaller worm gear may cause the worm to deflect more than the rest. You should also consider the bending angle of the pinion, which is a fundamental characteristic of geared motors. By knowing how the worm will deflect, you can choose the best teeth for your pinion.

Only the finest worm shaft for your transmission

If you need a worm shaft, it is available from CZPT. We process only the finest raw materials with our modern machines to always obtain the highest quality results. Drawing on our extensive expertise, we offer a range of worm shafts in standard sizes, but custom options are also available.
