Ever-Power worm gearboxes have earned a reputation to be a business benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a wide 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 speed gear ratio. Being basic and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively bigger) and its own body is generally quite long in the axial path. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single 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 definitely shaped like a screw and the worm wheel is a kind of gear machined to have a tooth profile with the same configuration.
The operation of a worm gear is similar 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 path when the bolt is certainly turned.
The design of a worm gear is considered through the relationship between your 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. Due to 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 due to the structure. This characteristic makes it possible to layout the turning transmitting 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 selection of shaft layouts is among 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 total of 14 types (Physique 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 because 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 gear, elevators and escalators, etc.

Key points when selecting 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 key areas such as selecting the load index, calculating the overhang load and examining heat rated capability from the manufacturer.
Cautions during use
When using a worm reduction gears, the 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 decrease gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it’s important to change the lubricating oil and also to change the lubricating oil from then on about 1 time per 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, having 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 suit a broad selection of applications and higher efficiency compared to the compact line XC, where in fact the emphasis is on space effectiveness.
Series H supplies the same features as series X with an added plus: a spur equipment pre-stage at the insight end provides higher functionality and a broader range of ratios than the X series.
Frame sizes 110 and 90 feature a cast-iron housing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is produced from casehardened and hardened alloy steel 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, output flange, single or double extension output shaft, torque limiter with through cable, torque arm.
