EP worm gearboxes have earned a status to be a business benchmark worldwide. Our achievement originated from our relentless get for top quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and electric motor interfaces, produces the EP worm gearbox the default decision for the industry. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
EP Worm gearboxes provide great torque with low swiftness gear ratio. Being simple and compact in style, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix position is typically comparatively larger) and its own body is normally quite long 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. Obtainable in Solid shafts (one or dual), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a type of interlocking gear composed of a worm shaft and worm wheel. The worm is certainly shaped just like a screw and the worm wheel is usually a type of gear machined to have a tooth account with the same configuration.
The procedure of a worm gear is similar 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 for that reason progresses in the axial direction when the bolt is usually 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
Substantial 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 particular applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature can help you layout the turning transmitting direction at a 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 change the rotation path of the worm wheel by changing the screw path.
A multitude 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 total of 14 types (Determine 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 usually linear and the relative slide is fantastic. In comparison to rolling power transmission, noise and vibration are really low. For this reason, this technology is utilized to drive medical apparatus, 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 key areas such as selecting the strain index, calculating the overhang load and examining the heat rated ability from the manufacturer.
Cautions during use
When using a worm reduction gears, the heat produced during 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 reduction 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 per year according to the operation manual offered 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) offers great versatility to suit a broad range of applications and higher efficiency compared to the compact brand XC, where the emphasis is on space efficiency.
Series H supplies the same features since series X with an extra plus: a spur equipment pre-stage at the input end provides higher performance and a good broader selection of ratios compared to the X series.
Framework 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 output shaft is supplied as standard.
Broad range of options available:
second input, result flange, single or dual extension output shaft, torque limiter with through cable connection, torque arm.
