Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix position is typically comparatively larger) and its own body is generally quite long in the axial path. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or double), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a kind of interlocking gear composed of a worm shaft and worm wheel. The worm can be shaped like a screw and the worm wheel is definitely a kind of gear machined to possess a tooth profile with the same configuration.
The operation of a worm gear is similar with that of a bolt and nut. The principle is equivalent to a nut that is fixed so that it cannot rotate and for that reason progresses in the axial path when the bolt is turned.
The design of a worm gear is thought of through the relationship between your rack and spur gear on the center plane of the worm wheel.
Features
High reduction ratio One rotation of the worm rotates the worm wheel by one tooth. Because of this, in a 1 speed reduction gears, the wheel could be manufactured so that it’ll be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature makes it possible to layout the turning tranny direction at a right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). You’ll be able to change the rotation path of the worm wheel by changing the screw path.
A multitude of shaft layouts The wide selection of shaft layouts is one of the top features of interlocking gears.For instance, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Shape 2) and, if attachment orientations are included, you’ll be able to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel can be characteristic because the contact can be linear and the relative slide is great. In comparison to rolling power transmission, sound and vibration are really low. For this reason, this technology can be used to drive medical devices, elevators and escalators, etc.

Key points when selecting a worm reduction gears
Izbor
When choosing a worm reduction gears, the procedures for selecting the right gear are described in the maker catalogs and the series and models should be selected according to those procedures. Particular care ought to be taken in important areas such as for example selecting the strain index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When using a worm decrease gears, the heat produced through the initial period of make use of is high and running-in procedure at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is key to sufficiently attaining the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it is necessary to change the lubricating oil and to change the lubricating oil from then on about 1 time each year according to the procedure manual provided by the manufacturer.

The worm reduction gears come in two series: X and H.
The series X, having a worm and worm wheel set, is available in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell casing + coupling) provides great versatility to suit a broad selection of applications and higher efficiency than the compact series XC, where the emphasis is on space performance.
Series H supplies the same features because series X with an extra plus: a spur gear pre-stage at the insight end provides higher overall performance and a broader range of ratios compared to the X series.
Frame sizes 110 and 90 include a cast-iron housing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is produced from casehardened and hardened alloy metal and ground-finished.
The worm wheel has a cast iron hub with cast bronze insert. Hollow result shaft is supplied as standard.
Broad range of possibilities:
second input, output flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
