Ever-Power worm gearboxes possess earned a popularity to be a business 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 flexibility accorded through a wide choice of mounting options, 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 version, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low quickness gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite lengthy in the axial direction. The gears in these gearboxes could 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. 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 such as a screw and the worm wheel is definitely a type of gear machined to have 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 the same as a nut that is fixed so that it cannot rotate and therefore 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 middle 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 therefore that it’ll be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic can help you layout the turning transmission direction at a right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). It is possible to change the rotation path of the worm wheel by changing the screw path.
A multitude of shaft layouts The wide selection of shaft layouts is among the features of interlocking gears.For example, right shaft output, remaining 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 select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel can be characteristic because the contact is definitely linear and the relative slide is excellent. In comparison to rolling power transmission, sound and vibration are extremely low. For this reason, this technology is used to drive medical gear, 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 ought to be taken in key areas such as selecting the load index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, heat produced during 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 is necessary to change the lubricating oil and to change the lubricating oil from then on about 1 time per year according to the procedure manual supplied by the manufacturer.

The worm reduction gears come 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 suit a broad selection 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 since series X with an added plus: a spur equipment pre-stage at the insight end provides higher overall performance and a broader selection of ratios compared to the X series.
Body sizes 110 and 90 feature a cast-iron casing 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 comes as standard.
Broad range of options available:
second input, result flange, single or double extension output shaft, torque limiter with through cable, torque arm.
