EP worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes happen to be affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and engine interfaces, makes the EP worm gearbox the default decision for the industry. The helical-worm and the double-worm edition, 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 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 normally quite lengthy in the axial direction. The gears in these gearboxes could be proper or left-handed dependant on the purpose.
Mounting option include universal housing, part 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 kind of interlocking gear made up of a worm shaft and worm wheel. The worm is usually shaped just like a screw and the worm wheel is usually a type of gear machined to own a tooth account with the same configuration.
The operation of a worm gear is comparable 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 direction when the bolt is usually turned.
The look of a worm gear is thought of through the relationship between your 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. Due to this, in a 1 speed reduction gears, the wheel can be manufactured thus that it will be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This feature can help you layout the turning tranny 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 transformation the rotation direction of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide selection 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 (Physique 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 can be characteristic since the contact is usually linear and the relative slide is fantastic. In comparison to rolling power transmission, sound and vibration are really low. For this reason, this technology is used to drive medical devices, elevators and escalators, etc.

Key points when selecting a worm reduction gears
選択
When choosing a worm reduction gears, the procedures for selecting the right 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 important areas such as selecting the load index, calculating the overhang load and examining the heat rated capacity 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 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 decrease gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it’s important to improve the lubricating oil and also to change the lubricating oil after that about 1 time each 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, having 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 suit a broad selection of applications and provides higher efficiency compared to the compact collection XC, where in fact the emphasis is on space performance.
Series H supplies the same features because series X with an added plus: a spur equipment pre-stage at the input end provides higher functionality and a good broader selection of ratios than 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 metal and ground-finished.
The worm wheel includes 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 dual extension output shaft, torque limiter with through cable connection, torque arm.
