Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and engine 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, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low rate gear ratio. Being simple and compact in design, 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 position is typically comparatively larger) and its body is generally quite long in the axial direction. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, part 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 composed of a worm shaft and worm wheel. The worm is definitely shaped such as a screw and the worm wheel is certainly a type of gear machined to possess 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 is fixed to ensure 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 your 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. Due to this, in a 1 speed reduction gears, the wheel can be manufactured therefore that it will be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature can help you layout the turning tranny direction at the 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 top 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 usually linear and the relative slide is fantastic. In comparison with rolling power transmission, sound and vibration are extremely low. For this reason, this technology can be used to drive medical devices, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
When choosing a worm reduction gears, the procedures for selecting the right 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 load index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When using a worm reduction gears, the heat produced through the initial period of use is high and running-in operation 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 operation (approximately 50 hours), it is necessary to change the lubricating oil and also to change the lubricating oil from then on about 1 time each year according to the procedure 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) provides great versatility to suit a broad range of applications and provides higher efficiency than the compact series XC, where the emphasis is on space effectiveness.
Series H offers the same features because series X with an extra plus: a spur equipment pre-stage at the input end provides higher overall performance 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 use die-cast aluminium housings. The worm shaft is manufactured from casehardened and hardened alloy steel 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, output flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
