Ever-Power worm gearboxes possess earned a status to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine 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, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low quickness gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its own body is generally quite lengthy in the axial direction. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or double), 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 is definitely shaped just like a screw and the worm wheel is usually a kind of gear machined to get 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 has been fixed so that it cannot rotate and therefore progresses in the axial path when the bolt can be turned.
The design 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 by one tooth. For this reason, in a 1 speed reduction gears, the wheel could be manufactured therefore that it will 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). 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 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 complete of 14 types (Figure 2) and, if attachment orientations are included, you’ll be able 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 great. In comparison to rolling power transmission, sound and vibration are really low. For this reason, this technology can be used to drive medical apparatus, 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 should be taken in essential areas such as for example selecting the strain index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, the 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 key to sufficiently achieving the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it’s important to improve the lubricating oil and 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, comes in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell casing + coupling) offers great versatility to match a broad range of applications and higher efficiency compared to the compact collection XC, where in fact the emphasis is on space efficiency.
Series H offers the same features because series X with an added plus: a spur equipment pre-stage at the input end provides higher efficiency and a broader range of ratios than 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 manufactured 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 possibilities:
second input, output flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
