EP worm gearboxes have earned a status to be a business benchmark worldwide. Our achievement came from our relentless get for quality with state-of-the-art technology, all and will be offering worm gearboxes will be affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, causes the EP worm gearbox the default decision for the market. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
EP Worm gearboxes provide excessive torque with low speed gear ratio. Being simple and compact in style, 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 own body is generally quite lengthy in the axial direction. 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. Available 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 definitely shaped like a screw and the worm wheel is a kind of gear machined to have 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 to ensure that it cannot rotate and for that reason progresses in the axial path 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
Excessive 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’ll 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 transmission direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). It is possible to change the rotation path of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide variety of shaft layouts is among the features of interlocking gears.For instance, 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 since the contact is certainly 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 used to drive medical gear, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
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 heat rated capacity from the manufacturer.
Cautions during use
When using a worm decrease gears, the heat produced during the initial amount 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 attaining 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 also to change the lubricating oil after that about 1 time each year according to the procedure manual furnished 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) offers great versatility to match a broad selection of applications and higher efficiency than the compact collection XC, where the emphasis is on space efficiency.
Series H offers the same features as 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 than the X series.
Frame sizes 110 and 90 feature 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 has a cast iron hub with cast bronze insert. Hollow output shaft comes as standard.
Broad range of options available:
second input, output flange, single or double extension result shaft, torque limiter with through wire, torque arm.
