Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are inexpensive prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm edition, 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 velocity gear ratio. Being simple and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively larger) and its body is generally quite long in the axial direction. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting choice include universal housing, aspect 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 kind of interlocking gear made up of a worm shaft and worm wheel. The worm is usually shaped just like a screw and the worm wheel is definitely a kind of gear machined to get a tooth profile with the same configuration.
The procedure of a worm gear is comparable 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 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 by one tooth. For this reason, in a 1 speed decrease gears, the wheel could be manufactured so 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). It is possible to change the rotation path of the worm wheel by changing the screw path.
A multitude of shaft layouts The wide variety of shaft layouts is one of the top features of interlocking gears.For instance, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Determine 2) and, if attachment orientations are included, it is possible to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is characteristic because the contact is usually linear and the relative slide is fantastic. In comparison to rolling power transmission, sound and vibration are extremely low. For this reason, this technology is used to drive medical products, elevators and escalators, etc.

Key points when choosing 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 should be selected according to those procedures. Particular care should be taken in important 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 during 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 paramount to sufficiently attaining the performance of the worm decrease 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 after that about 1 time per year according to the operation manual offered 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, is available in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell housing + coupling) offers great versatility to suit a broad range of applications and provides higher efficiency than 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 gear pre-stage at the input end provides higher efficiency and a broader range of ratios compared to the X series.
Body sizes 110 and 90 feature 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 steel and ground-finished.
The worm wheel includes a cast iron hub with cast bronze insert. Hollow result shaft is supplied as standard.
Broad range of options available:
second input, output flange, single or double extension result shaft, torque limiter with through cable, torque arm.
