EP worm gearboxes possess earned a popularity to be a business benchmark worldwide. Our achievement originated from our relentless travel for top quality with state-of-the-art technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and electric motor interfaces, creates the EP worm gearbox the default decision for the market. 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.
EP Worm gearboxes provide high torque with low swiftness 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 position is typically comparatively larger) and its body is generally quite lengthy in the axial path. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect 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
A worm gear is a kind of interlocking gear made up of a worm shaft and worm wheel. The worm is usually shaped like a screw and the worm wheel is usually a kind of gear machined to possess a tooth profile with the same configuration.
The operation of a worm gear is similar 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 usually 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.
Large reduction ratio One rotation of the worm rotates the worm wheel by one tooth. Because of this, in a 1 speed reduction gears, the wheel could be manufactured hence that it’ll 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 transmission 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 path of the worm wheel by changing the screw direction.
A wide variety of shaft layouts The wide variety of shaft layouts is one of the features of interlocking gears.For instance, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Determine 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 usually characteristic because the contact can be linear and the relative slide is great. In comparison to rolling power transmission, noise and vibration are really low. Because of this, this technology is utilized to drive medical apparatus, elevators and escalators, etc.

Key points when selecting a worm reduction gears
When selecting a worm reduction gears, the procedures for selecting the correct gear are described in the maker catalogs and the series and models should be selected according to those procedures. Particular care should be taken in crucial areas such as selecting the strain index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When using a worm decrease gears, heat produced during the initial period of use is large 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 procedure (approximately 50 hours), it’s important to change 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.

They succeeded in merging uncompromising top quality with stateoftheart technology amd renown price effectiveness.Absolute versatility is given by the wide selection of several mounting options, shaft configurations and motor interface, all offered as standard. The helicalworm and the doubleworm version, with or without the torque limiter, also add up, creating an extremely versatile drive system.
20 level C TO 80 level C
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 match a broad selection of applications and higher efficiency than the compact line XC, where in fact the emphasis is on space performance.
Series H supplies the same features since series X with an added plus: a spur gear pre-stage at the input end provides higher efficiency and a good broader selection of ratios compared to the X series.
Framework sizes 110 and 90 feature a cast-iron housing cast enbloc, whereas smaller sizes use 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 output shaft comes as standard.
Broad range of possibilities:
second input, output flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
