Ever-Power worm gearboxes possess earned a status to be an industry benchmark worldwide. Our success originated 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 broad choice of mounting choices, shaft configurations and electric 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 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 compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its body is normally quite long in the axial path. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting option include universal housing, side 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 usually shaped just like a screw and the worm wheel is certainly a kind of gear machined to get 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 is fixed to ensure that it cannot rotate and for that reason progresses in the axial direction when the bolt is turned.
The look of a worm gear is considered 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 by one tooth. For this reason, in a 1 speed decrease gears, the wheel can be manufactured so that it will be rotated 1/60 (1/120 in unique applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature makes it possible to layout the turning tranny direction at the 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 path of the worm wheel by changing the screw direction.
A wide variety of shaft layouts The wide variety of shaft layouts is one of the features of interlocking gears.For instance, 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, you’ll be able to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is certainly characteristic because the contact is linear and the relative slide is great. In comparison with rolling power transmission, sound and vibration are really low. Because of this, this technology is utilized to drive medical equipment, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
When selecting a worm reduction gears, the procedures for selecting the correct gear are described in the manufacturer 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 the heat rated capability from the manufacturer.
Cautions during use
When utilizing a worm reduction gears, heat produced during 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 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 after that about 1 time each year according to the procedure manual offered 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, is available 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 range XC, where in fact the emphasis is on space efficiency.
Series H supplies the same features since series X with an extra plus: a spur equipment pre-stage at the input end provides higher functionality and a broader range of ratios compared to the X series.
Framework sizes 110 and 90 include a cast-iron housing 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 includes a cast iron hub with cast bronze insert. Hollow result shaft is supplied as standard.
Broad range of options available:
second input, result flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
