Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a broad 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, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively bigger) and its body is normally quite lengthy in the axial path. The gears in these gearboxes could be right or left-handed dependant on the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), 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 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 equivalent to a nut that has been fixed to ensure that it cannot rotate and therefore progresses in the axial direction when the bolt is usually turned.
The design 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. For this reason, in a 1 speed decrease gears, the wheel could be manufactured therefore 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 can be clockwise or counterclockwise (generally clockwise). You’ll be able to change the rotation direction of the worm wheel by changing the screw direction.
A multitude of shaft layouts The wide selection of shaft layouts is one of 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 total of 14 types (Shape 2) and, if attachment orientations are included, you’ll be able to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is definitely characteristic since the contact is usually linear and the relative slide is fantastic. In comparison to rolling power transmission, sound and vibration are really 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 choosing 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 ought to 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 during 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 key to sufficiently achieving the performance of the worm decrease gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it is necessary to improve the lubricating oil and to change the lubricating oil after that about 1 time per year according to the operation manual provided 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 housing + coupling) provides great versatility to suit a broad range of applications and higher efficiency than the compact range XC, where the emphasis is on space effectiveness.
Series H offers the same features because series X with an extra plus: a spur gear pre-stage at the input end provides higher efficiency and a broader selection of ratios than the X series.
Framework sizes 110 and 90 include a cast-iron casing 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 has a cast iron hub with cast bronze insert. Hollow output 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.
