This gearbox utilizes a 30:1 ratio worm-drive reduction for worm wheel gearbox applications that require extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but also eliminates back-traveling the gearmotor so a posture can be kept even when power isn’t applied. The precision floor 3/8” stainless steel result shaft is supported by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and light weight aluminum structure provides a rigid framework without adding unnecessary weight and is easily mounted to any flat surface by utilizing the base mounting tabs. Our Standard Spur Gear motors will work with this gearbox (electric motor sold separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-quickness applications that want high precision and torque.

High reduction gear
Worm and wheel gear pairings provide large speed decrease ratios with only 1 gear pairing in a far more compact space in comparison to other types of gears. You can expect up to a maximum ratio of 100:1 with this products. Another benefit of the Worm and Wheel equipment pairings may be the low level noise they produce. Some disadvantages are the general low performance and the fact that they generate heat.
Benefit of EP’s Worm Gears – “Cool rolled Worm Gears”
1) The hardness of the helicoid surface area has been achieved by function hardening when the chilly rolling was performed, providing Worm gears with better mechanical properties than machined worms due to reality that the metallic fibrous structure is not cut.
2) The top hardness after chilly rolling is increased by 1.2 to at least one 1.3 times in comparison to the hardness of the initial material, and the hardness of the helicoid surface area increases to around HB240 to 260.
3) Cold rolled worms are suitable for miniature equipment applications since this could be rotated smoothly without damaging the worm wheels made out of POM or additional soft materials.
4) Due to the implementation of the cold rolling method, the helicoid surface of EP-Worm (M0.5 to 2.0) comes away with a mirror like finish. Thus, EP-Precision Cool Rolled Worms give a smooth procedure and long-term durability.
Worm gears are made of a worm and a equipment (sometimes known as a worm wheel), with nonparallel, nonintersecting shafts oriented 90 degrees to each other. The worm is definitely analogous to a screw with a V-type thread, and the apparatus is certainly analogous to a spur equipment. The worm is typically the traveling component, with the worm’s thread advancing the teeth of the gear.
Like a ball screw, the worm in a worm gear may have an individual start or multiple starts – and therefore there are multiple threads, or helicies, on the worm. For a single-start worm, each full change (360 degrees) of the worm advances the equipment by one tooth. Therefore a gear with 24 teeth provides a gear reduced amount of 24:1. For a multi-begin worm, the gear reduction equals the amount of teeth on the apparatus, divided by the number of begins on the worm. (That is different from almost every other types of gears, where in fact the gear reduction can be a function of the diameters of both components.)
The meshing of the worm and the gear is an assortment of sliding and rolling actions, but sliding contact dominates at high reduction ratios. This sliding action causes friction and heat, which limits the performance of worm gears to 30 to 50 percent. To be able to minimize friction (and for that reason, high temperature), the worm and equipment are constructed with dissimilar metals – for example, the worm could be made of hardened metal and the gear made of bronze or aluminum.
Although the sliding contact reduces efficiency, it provides extremely quiet operation. (The use of dissimilar metals for the worm and gear also plays a part in quiet operation.) This makes worm gears ideal for use where noise should be minimized, such as for example in elevators. Furthermore, the use of a softer materials for the apparatus means that it could absorb shock loads, like those skilled in heavy equipment or crushing devices.
The primary benefit of worm gears is their ability to provide high reduction ratios and correspondingly high torque multiplication. They can also be used as swiftness reducers in low- to medium-swiftness applications. And, because their reduction ratio is based on the number of gear teeth by itself, they are smaller sized than other types of gears. Like fine-pitch lead screws, worm gears are typically self-locking, which makes them perfect for hoisting and lifting applications.
Worms & Worm Gears
EP Gear’s worms and worm gears provide a highly effective answer for power tranny applications requiring high-ratio speed reduction in a restricted space using correct angle (90°), nonintersecting shafts. When properly applied, worms and worm gears supply the smoothest, quietest type of gearing.
Because the performance of a worm gear drive depends upon the business lead angle and amount of begins on the worm – and because increased efficiency is always an objective, the ratio should be kept only possible. To run properly, worms and worm gears used together must have the same diametral pitch and threads.
Our complete type of worms and worm gears can be ordered through the EP Gear Guaranteed Same Time Shipment Program for the fastest delivery possible.

How exactly to Select High Efficient Worm Gearbox?
The worm gear manufacturing process is also relatively simple. Nevertheless, there exists a low transmission efficiency problem if you don’t understand the how to select the worm gearbox. 3 basic indicate choose high worm equipment efficiency that you need to know:
1) Helix position. The worm equipment drive efficiency mostly depend on the helix position of the worm. Generally, multiple thread worms and gears can be more efficient than one thread worms. Proper thread worms can increase performance.
2) Lubrication. To choose a brand lubricating essential oil is an essential factor to improve worm gearbox performance. As the correct lubrication can reduce worm gear action friction and warmth.
3) Material selection and Gear Manufacturing Technology. For worm shaft, the material should be hardened steel. The worm gear materials should be aluminium bronze. By reducing the worm equipment hardness, the friction on the worm the teeth is decreased. In worm manufacturing, to use the specialized machine for gear trimming and tooth grinding of worms also can increase worm gearbox effectiveness.
From a sizable transmission gearbox capacity to an even small worm gearbox load, you can choose one from a wide range of worm reducer that precisely fits your application requirements.
Worm Gear Package Assembly：
1) You can complete the installation in six different ways.
2) The installation should be solid and reliable.
3) Make sure to examine the connection between the electric motor and the worm gear reducer.
4) You must make use of flexible cables and wiring for a manual set up.
With the help of the innovative science and drive technology, we have developed several unique “square box” designed from high-quality aluminium die casting with a beautiful appearance. The modular worm gearbox style series: worm drive gearbox, parallel shaft gearbox, bevel helical gearbox, spiral bevel gearbox, coaxial gearbox, right angle gearbox. An NMRV series gearbox is usually a standard worm gearbox with a bronze worm equipment and a worm. Our Helical gearbox product line consists of four universal series (R/S/K/F) and a step-less rate variation UDL series. Their framework and function act like an NMRV worm gearbox.
In the EP worm gears, the output shaft is offset by 90° from the drive shaft. A dual shaft for double-sided result or a cover for the short shaft end are optionally available as components. EP gearboxes have a high-quality, long-term synthetic lubricant based on polyethylene glycol, and are therefore maintenancefree. They are seen as a high performance and self-locking.
Due to their relatively high backlash (~1-2°), worm gears aren’t ideal for positioning applications.
Worm Gear applications
Application of worm gears, which is comparable to a standard spur and the worm, which really is a cylindrical equipment that resembles a screw, permits smaller gearboxes or planetary drives, whilst retaining torque or power. It is common for worm gears to have reductions of 20:1, and actually up to 300:1 or greater.
Usual gearing includes the unique capability which other gearing components don’t have – the “worm” can effortlessly spin the part, however the “gears” cannot maneuver and fully rotate the worm-zone.
What’s the reason behind this inability to rotate the gear-worm?
The angle isn’t deep enough on the worm, so when the gear attempts to rotate the worm, high frictional pressure between worm shaft and gear parts keep the zone stuck constantly in place.
