EP worm gearboxes possess earned a status to be a business benchmark worldwide. Our success came from our relentless get for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and electric motor interfaces, produces the EP worm gearbox the default choice for the market. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
EP Worm gearboxes provide excessive torque with low speed gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its 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 (one or double), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a kind of interlocking gear composed of a good worm shaft and worm wheel. The worm is shaped such as a screw and the worm wheel is definitely a kind of gear machined to get a tooth account 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 has been fixed so that it cannot rotate and therefore progresses in the axial direction when the bolt is definitely turned.
The look of a worm gear is thought of through the relationship between the rack and spur gear on the center plane of the worm wheel.
Features
Huge reduction ratio One rotation of the worm rotates the worm wheel simply by one tooth. Because of this, in a 1 speed reduction gears, the wheel can be manufactured therefore that it’ll be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature makes it possible to layout the turning transmission direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm can be clockwise or counterclockwise (generally clockwise). It is possible to modification the rotation path of the worm wheel by changing the screw direction.
A wide variety of shaft layouts The wide selection of shaft layouts is among the features of interlocking gears.For example, right shaft output, still 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, you’ll be able to select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel can be characteristic because the contact is definitely linear and the relative slide is great. In comparison to rolling power transmission, noise and vibration are really low. For this reason, this technology is utilized to drive medical devices, 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 maker 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 strain index, calculating the overhang load and examining heat rated capability from the manufacturer.
Cautions during use
When utilizing a worm lowering gears, the heat produced through the initial amount of use is high and running-in operation 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 reduction 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 each year according to the operation 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 housing + coupling) provides great versatility to match a broad range of applications and provides higher efficiency than the compact brand XC, where in fact the emphasis is on space performance.
Series H supplies the same features since series X with an extra plus: a spur gear pre-stage at the insight end provides higher performance and a good broader range of ratios compared to the X series.
Body sizes 110 and 90 include a cast-iron casing 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 includes a cast iron hub with cast bronze insert. Hollow result shaft comes as standard.
Broad range of options available:
second input, result flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
