Ever-Power worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a wide choice of mounting choices, 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, add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low swiftness gear ratio. Being basic and compact in design, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type qualities act like 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 can be correct or left-handed depending upon the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or dual), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a type of interlocking gear composed of a worm shaft and worm wheel. The worm is usually shaped such as a screw and the worm wheel is usually a kind of gear machined to have a tooth profile with the same configuration.
The procedure of a worm gear is comparable with that of a bolt and nut. The principle is the same as a nut that has been fixed so that it cannot rotate and for that reason progresses in the axial path when the bolt can be turned.
The look of a worm gear is considered through the relationship between your 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 simply by one tooth. Because of this, in a 1 speed decrease gears, the wheel can be manufactured therefore that it’ll be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This characteristic can help you layout the turning transmission direction at the 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 direction 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 example, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Body 2) and, if attachment orientations are included, it is possible to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is certainly characteristic because the contact can be linear and the relative slide is fantastic. In comparison to rolling power transmission, noise and vibration are really low. Because of this, this technology can be used to drive medical equipment, elevators and escalators, etc.

Key points when selecting a worm reduction gears
Selection
When choosing a worm reduction gears, the procedures for selecting the correct gear are described in the manufacturer catalogs and the series and models should be selected according to those procedures. Particular care ought to be taken in crucial areas such as for example selecting the load index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, the heat produced through 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 paramount 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 after that about 1 time each year according to the procedure manual supplied by the manufacturer.

The worm reduction gears can be found 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 housing + coupling) offers great versatility to match a broad selection of applications and provides 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.
Frame sizes 110 and 90 feature a cast-iron housing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is manufactured from casehardened and hardened alloy metal and ground-finished.
The worm wheel has a cast iron hub with cast bronze insert. Hollow output 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.
