Ever-Power worm gearboxes possess earned a status to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are inexpensive prices. High versatility accorded through a broad choice of mounting options, shaft configurations and electric motor 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, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low swiftness gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively bigger) and its body is normally quite lengthy in the axial path. The gears in these gearboxes could be right or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or dual), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a kind of interlocking gear made up of a worm shaft and worm wheel. The worm is shaped such as a screw and the worm wheel is certainly a kind of gear machined to have a tooth profile with the same configuration.
The operation of a worm gear is comparable with that of a bolt and nut. The principle is equivalent to a nut that has been fixed to ensure that it cannot rotate and therefore progresses in the axial path when the bolt can be turned.
The design of a worm gear is thought of through the relationship between the 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 simply by one tooth. For this reason, in a 1 speed reduction gears, the wheel could be manufactured therefore that it will be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This characteristic makes it possible to layout the turning transmission direction at a right angle.
The arbitrariness of the rotation direction The screw direction of the worm can be clockwise or counterclockwise (generally clockwise). It is possible 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 among the top features of interlocking gears.For instance, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Figure 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 is linear and the relative slide is great. In comparison with rolling power transmission, noise and vibration are extremely low. For this reason, this technology is utilized to drive medical apparatus, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
When choosing a worm reduction gears, the procedures for selecting the correct gear are described in the maker catalogs and the series and models ought to be selected according to those procedures. Particular care should be taken in essential areas such as selecting the strain index, calculating the overhang load and examining heat rated capacity from the manufacturer.
Cautions during use
When utilizing a worm reduction gears, the heat produced during the initial period of use 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 decrease gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it’s important 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, featuring a worm and worm wheel set, comes in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell casing + coupling) provides great versatility to match a broad selection of applications and higher efficiency compared to the compact collection XC, where in fact the emphasis is on space efficiency.
Series H supplies the same features because series X with an extra plus: a spur gear pre-stage at the insight end provides higher efficiency and a broader selection of ratios compared to the X series.
Body sizes 110 and 90 feature a cast-iron housing cast enbloc, whereas smaller sizes make use of 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 output shaft is supplied as standard.
Broad range of possibilities:
second input, result flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
