EP worm gearboxes possess earned a popularity to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes happen to be affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, would make the EP worm gearbox the default choice for the sector. 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 great torque with low speed gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively bigger) and its own body is generally quite lengthy in the axial path. 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
A worm gear is a type of interlocking gear composed of a worm shaft and worm wheel. The worm is definitely shaped such as a screw and the worm wheel is a type of gear machined to get 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 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 design of a worm gear is thought of through the relationship between the rack and spur gear on the middle plane of the worm wheel.
High reduction ratio One rotation of the worm rotates the worm wheel by one tooth. For this reason, in a 1 speed decrease gears, the wheel could be manufactured thus that it’ll be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic 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 could be clockwise or counterclockwise (generally clockwise). You’ll be able to switch the rotation direction 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, still left shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Shape 2) and, if attachment orientations are included, it is possible 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, sound and vibration are extremely low. Because of this, this technology is used to drive medical equipment, elevators and escalators, etc.

Key points when selecting a worm reduction gears
When choosing a worm reduction gears, the procedures for selecting the correct gear are described in the manufacturer catalogs and the series and models ought to be selected according to those procedures. Particular care should be taken in crucial 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 operation at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is paramount 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 change the lubricating oil and to change the lubricating oil after that about 1 time per year according to the operation manual offered by the manufacturer.
The Worm Decrease Gear Box is provided by our company is of supreme quality. Our products are made by using premium quality material and advance technology at our vendors end. They are widely used in various sectors. Our goods are often available at a very low market prices.

20 level C TO 80 level C
The worm reduction gears come 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) provides great versatility to suit a broad range of applications and provides higher efficiency compared to the compact brand XC, where in fact the emphasis is on space performance.
Series H offers the same features as series X with an added plus: a spur equipment pre-stage at the insight end provides higher efficiency and a good broader selection 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 manufactured from casehardened and hardened alloy steel and ground-finished.
The worm wheel includes a cast iron hub with cast bronze insert. Hollow result shaft is supplied as standard.
Broad range of possibilities:
second input, output flange, single or double extension result shaft, torque limiter with through cable connection, torque arm.
