Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our success came 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 industry. The helical-worm and the double-worm version, 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 quickness gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm decrease 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 path. 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 composed of a worm shaft and worm wheel. The worm is usually shaped like a screw and the worm wheel can be a type 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 equivalent to a nut that is fixed to ensure that it cannot rotate and therefore progresses in the axial direction when the bolt can be turned.
The look of a worm gear is considered 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 simply 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 particular applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic 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). It is possible to change the rotation direction of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide variety of shaft layouts is among the features of interlocking gears.For instance, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Determine 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 definitely characteristic because the contact can be linear and the relative slide is fantastic. In comparison with rolling power transmission, sound and vibration are really low. For this reason, this technology is utilized to drive medical gear, elevators and escalators, etc.

Key points when choosing 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 should be selected according to those procedures. Particular care ought to be taken in key areas such as selecting the strain 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 during 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 attaining 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 also to change the lubricating oil after that 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, is available 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 than the compact series XC, where in fact the emphasis is on space effectiveness.
Series H supplies the same features since series X with an added plus: a spur equipment pre-stage at the input end provides higher overall performance 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 use die-cast aluminium housings. The worm shaft is manufactured from casehardened and hardened alloy metal and ground-finished.
The worm wheel includes a cast iron hub with cast bronze insert. Hollow output shaft is supplied as standard.
Broad range of Worm Reducer possibilities:
second input, output flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
