EP worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and engine interfaces, creates the EP worm gearbox the default choice for the sector. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
EP Worm gearboxes provide huge torque with low velocity gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively larger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes can be correct 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 (one or dual), with torque arm or torque limiter.
Worm reduction gears features
A worm gear is a kind of interlocking gear made up of a worm shaft and worm wheel. The worm is definitely shaped like a screw and the worm wheel can be a kind of gear machined to have 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 equivalent to a nut that is fixed so that it cannot rotate and therefore progresses in the axial path when the bolt is definitely 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.
Large reduction ratio One rotation of the worm rotates the worm wheel by one tooth. Due to this, in a 1 speed reduction gears, the wheel can be manufactured therefore that it’ll be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature makes it possible to layout the turning tranny direction at a 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 modification the rotation direction 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 (Figure 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 since the contact is usually linear and the relative slide is fantastic. In comparison with rolling power transmission, sound and vibration are really low. Because of this, this technology is used to drive medical devices, elevators and escalators, etc.

Key points when choosing a worm reduction gears
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 ought to be taken in essential areas such as selecting the load index, calculating the overhang load and examining the heat rated ability from the manufacturer.
Cautions during use
When utilizing a worm reduction gears, the heat produced through the initial amount 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 attaining the performance of the worm decrease gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it’s important to improve the lubricating oil and also to change the lubricating oil from then on about 1 time each year according to the operation manual given by the manufacturer.

20 level C TO 80 level C
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) offers great versatility to match a broad range of applications and higher efficiency than the compact collection XC, where in fact the emphasis is on space performance.
Series H supplies the same features as series X with an added plus: a spur gear pre-stage at the input end provides higher performance and a good broader selection of ratios compared to the X series.
Framework sizes 110 and 90 feature a cast-iron casing 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 is supplied as standard.
Broad range of possibilities:
second input, output flange, single or double extension output shaft, torque limiter with through wire, torque arm.
