EP worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our success came from our relentless travel for quality with state-of-the-art technology, all while offering worm gearboxes will be affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and electric motor interfaces, creates the EP worm gearbox the default decision 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.
EP Worm gearboxes provide huge torque with low speed gear ratio. Being basic and compact in design, these gears can achieve 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 bigger) and its own body is generally quite lengthy in the axial direction. The gears in these gearboxes can be proper or left-handed dependant on the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary 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 good worm shaft and worm wheel. The worm is certainly shaped such as a screw and the worm wheel is usually a kind of gear machined to have got 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 the same as a nut that has been fixed to ensure that it cannot rotate and therefore progresses in the axial direction when the bolt is definitely turned.
The look of a worm gear is considered through the relationship between the rack and spur gear on the center plane of the worm wheel.
Features
Large reduction ratio One rotation of the worm rotates the worm wheel by one tooth. For this reason, in a 1 speed reduction gears, the wheel can be manufactured hence that it will be rotated 1/60 (1/120 in unique 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 can be clockwise or counterclockwise (generally clockwise). You’ll be able to transformation 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 features of interlocking gears.For example, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., incorporate for a total of 14 types (Shape 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 definitely characteristic since the contact is certainly linear and the relative slide is excellent. In comparison with rolling power transmission, noise and vibration are really low. Because of this, this technology can be used to drive medical equipment, elevators and escalators, etc.

Key points when selecting a worm reduction gears
Selection
When choosing a worm reduction gears, the procedures for selecting the right gear are described in the maker catalogs and the series and models ought to be selected according to those procedures. Particular care should be taken in important areas such as selecting the strain index, calculating the overhang load and examining heat rated ability from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, the heat produced during the initial amount of use is large and running-in operation 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 is necessary to improve the lubricating oil and to change the lubricating oil after that about 1 time per year according to the procedure manual supplied by the manufacturer.

The worm reduction gears can be found in two series: X and H.
The series X, featuring 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) provides great versatility to match a broad selection of applications and higher efficiency compared to the compact series XC, where the emphasis is on space performance.
Series H offers the same features since series X with an extra plus: a spur equipment pre-stage at the insight end provides higher performance and a good broader range of ratios than the X series.
Frame sizes 110 and 90 include a cast-iron housing cast enbloc, whereas smaller sizes make use of die-cast aluminium housings. The worm shaft is produced from casehardened and hardened alloy steel and ground-finished.
The worm wheel has a cast iron hub with cast bronze insert. Hollow result shaft comes as standard.
Broad range of possibilities:
second input, output flange, single or dual extension output shaft, torque limiter with through wire, torque arm.
