Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. 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 quickness gear ratio. Being simple and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively bigger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting choice 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 composed of a worm shaft and worm wheel. The worm can be shaped like 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 the same as a nut that is fixed so that it cannot rotate and for that reason progresses in the axial direction when the bolt is certainly turned.
The design of a worm gear is considered through the relationship between the rack and spur gear on the middle 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 decrease gears, the wheel could be manufactured therefore that it’ll be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This feature can help you 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). 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 variety of shaft layouts is among the features of interlocking gears.For instance, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., combine for a complete 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 is characteristic since the contact can be linear and the relative slide is excellent. In comparison with rolling power transmission, noise and vibration are really 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 selecting a worm reduction gears, the procedures for selecting the right gear are described in the manufacturer catalogs and the series and models ought to be selected according to those procedures. Particular care ought to be taken in essential areas such as selecting the strain index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When using a worm reduction gears, the heat produced during the initial period of make use of is high and running-in operation at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is key to sufficiently achieving the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it’s important to change the lubricating oil and to change the lubricating oil from then on about 1 time per year according to the operation manual offered by the manufacturer.

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