Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable 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 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 reduction gears having screw type qualities act like 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 could be right or left-handed dependant on the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available 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 made up of a worm shaft and worm wheel. The worm can be shaped such as a screw and the worm wheel is definitely a type of gear machined to possess 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 to ensure that it cannot rotate and for that reason progresses in the axial path when the bolt is turned.
The look 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. Because of this, in a 1 speed decrease gears, the wheel could be manufactured so that it will be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature makes it possible to layout the turning transmitting direction at a 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, still 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, it is possible to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is usually characteristic because the contact is usually linear and the relative slide is fantastic. In comparison to rolling power transmission, sound and vibration are extremely low. For this reason, this technology is utilized to drive medical devices, 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 manufacturer catalogs and the series and models ought to be selected according to those procedures. Particular care ought to be taken in important areas such as for example selecting the load index, calculating the overhang load and examining the heat rated capacity from the manufacturer.
Cautions during use
When using a worm decrease gears, heat produced through 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 paramount to sufficiently achieving the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it is necessary to change the lubricating oil and also to change the lubricating oil from then on about 1 time per year according to the procedure 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, is available 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 provides higher efficiency than the compact collection XC, where the emphasis is on space effectiveness.
Series H supplies the same features as series X with an added plus: a spur equipment pre-stage at the input end provides higher performance and a broader range of ratios than the X series.
Framework sizes 110 and 90 feature a cast-iron casing cast enbloc, whereas smaller sizes use 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 comes as standard.
Broad range of options available:
second input, output flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
