Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the sector. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low swiftness gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively bigger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), 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 certainly shaped like a screw and the worm wheel is 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 direction when the bolt is usually 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 can be manufactured so that it’ll 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 tranny 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 direction of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide selection of shaft layouts is among the features of interlocking gears.For example, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Shape 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 can be characteristic because the contact is certainly linear and the relative slide is excellent. In comparison with rolling power transmission, noise and vibration are really low. Because of this, this technology is utilized to drive medical apparatus, elevators and escalators, etc.

Key points when selecting a worm reduction gears
Selection
When selecting 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 ought to be taken in essential areas such as selecting the load index, calculating the overhang load and examining heat rated capacity from the manufacturer.
Cautions during use
When using a worm reduction 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 key to sufficiently achieving the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it’s important to improve the lubricating oil and to change the lubricating oil from then on about 1 time each year according to the operation 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 casing + coupling) provides great versatility to match a broad selection of applications and higher efficiency compared to the compact series XC, where the emphasis is on space performance.
Series H supplies the same features as series X with an extra plus: a spur equipment pre-stage at the insight end provides higher performance and a broader selection of ratios than the X series.
Frame sizes 110 and 90 include 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 possibilities:
second input, result flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
