Ever-Power worm Worm Reducer gearboxes possess earned a reputation 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 affordable prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the sector. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being basic and compact in style, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively larger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes can be right or left-handed depending upon the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single 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 is usually shaped such as a screw and the worm wheel is usually a type 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 equivalent to a nut that has been fixed to ensure that it cannot rotate and for that reason progresses in the axial path when the bolt is certainly 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 by one tooth. For this reason, in a 1 speed reduction gears, the wheel can be manufactured so that it’ll be rotated 1/60 (1/120 in unique applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This feature can help you layout the turning transmitting direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). It is possible to change the rotation path of the worm wheel by changing the screw direction.
A multitude of shaft layouts The wide selection of shaft layouts is one of the features of interlocking gears.For example, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Body 2) and, if attachment orientations are included, it is possible to select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is certainly characteristic since the contact can be linear and the relative slide is excellent. In comparison to rolling power transmission, sound and vibration are extremely low. For this reason, this technology is utilized 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 right 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 important areas such as selecting the strain index, calculating the overhang load and examining heat rated capability from the manufacturer.
Cautions during use
When using a worm decrease gears, 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 paramount to sufficiently achieving 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 also to change the lubricating oil after that about 1 time each year according to the operation manual offered 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 suit a broad selection of applications and provides higher efficiency than the compact series XC, where in fact the emphasis is on space efficiency.
Series H supplies the same features since series X with an added plus: a spur gear pre-stage at the insight end provides higher functionality and a broader selection of ratios compared to the X series.
Frame sizes 110 and 90 feature a cast-iron casing cast enbloc, whereas smaller sizes use 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 is supplied as standard.
Broad range of possibilities:
second input, result flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
