Ever-Power worm gearboxes have earned a popularity 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 flexibility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being simple and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix position is typically comparatively larger) and its body is generally quite lengthy in the axial direction. The gears in these gearboxes can be correct 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 (one or dual), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a type of interlocking gear made up of a worm shaft and worm wheel. The worm is definitely shaped such as a screw and the worm wheel is certainly a kind of gear machined to possess a tooth profile with the same configuration.
The procedure of a worm gear is similar with that of a bolt and nut. The principle is the same as a nut that is fixed to ensure that it cannot rotate and therefore progresses in the axial direction when the bolt is usually turned.
The design of a worm gear is thought of 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 simply by one tooth. Because of this, in a 1 speed decrease gears, the wheel could be manufactured therefore that it will be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic can help you layout the turning transmitting direction at the 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 direction of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide variety 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 (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 can be characteristic because the contact is certainly linear and the relative slide is great. In comparison with rolling power transmission, noise and vibration are really low. For this reason, this technology is used to drive medical gear, 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 maker 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 load index, calculating the overhang load and examining heat rated capability from the manufacturer.
Cautions during use
When utilizing a worm reduction 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 improve the lubricating oil and also to change the lubricating oil from then on about 1 time each year according to the operation manual provided by the manufacturer.

The worm reduction gears can be found 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 casing + coupling) provides great versatility to match a broad range of applications and provides higher efficiency compared to the compact series XC, where in fact the emphasis is on space efficiency.
Series H supplies the same features because series X with an added plus: a spur gear pre-stage at the insight end provides higher functionality and a broader range of ratios than the X series.
Frame sizes 110 and 90 include a cast-iron casing 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 result shaft comes as standard.
Broad range of options available:
second input, result flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
