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-artwork technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a wide choice of mounting choices, 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, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low velocity gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively bigger) and its own body is generally quite long in the axial direction. The gears in these gearboxes could be right 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 kind of interlocking gear made up of a worm shaft and worm wheel. The worm is shaped like a screw and the worm wheel is definitely a type of gear machined to possess 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 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 design of a worm gear is considered through the relationship between the 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 by one tooth. Because of this, in a 1 speed decrease gears, the wheel could be manufactured therefore that it will be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally because of 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 could be clockwise or counterclockwise (generally clockwise). You’ll be able 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 one of the 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 (Physique 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 is definitely characteristic because the contact is linear and the relative slide is fantastic. In comparison to rolling power transmission, noise and vibration are extremely low. Because of this, this technology can be used to drive medical gear, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
When selecting 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 ought to be taken in important areas such as selecting the load index, calculating the overhang load and examining the heat rated capacity from the manufacturer.
Cautions during use
When using a worm decrease gears, the heat produced through 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 paramount to sufficiently achieving 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 to change the lubricating oil after that about 1 time each year according to the procedure manual provided 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 selection of applications and provides higher efficiency compared to the compact collection XC, where in fact the emphasis is on space performance.
Series H offers the same features because series X with an added plus: a spur equipment pre-stage at the insight end provides higher performance and a broader range of ratios compared to the X series.
Frame sizes 110 and 90 include 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 result shaft comes as standard.
Broad range of options available:
second input, output flange, single or double extension result shaft, torque limiter with through cable, torque arm.
