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 are affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and engine interfaces, creates the EP worm gearbox the default decision for the market. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
EP Worm gearboxes provide excessive torque with low acceleration 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 qualities act like helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or double), with torque arm or torque limiter.
Worm reduction gears features
A worm gear is a type of interlocking gear made up of a good worm shaft and worm wheel. The worm is certainly shaped such as a screw and the worm wheel is a type of gear machined to have got 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 to ensure that it cannot rotate and for that reason progresses in the axial path 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.
Huge 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 can be manufactured so 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 a 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 among the top 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, it is possible to select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is definitely characteristic since the contact is linear and the relative slide is great. In comparison with rolling power transmission, noise and vibration are really low. Because of this, this technology is utilized to drive medical products, elevators and escalators, etc.

Key points when selecting a worm reduction gears
When choosing a worm reduction gears, the procedures for selecting the right 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 for example selecting the load index, calculating the overhang load and examining heat rated potential from the manufacturer.
Cautions during use
When using a worm decrease gears, heat produced through 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 paramount to sufficiently achieving the performance of the worm decrease gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it is necessary to change the lubricating oil and also to change the lubricating oil after that about 1 time per year according to the procedure manual offered by the manufacturer.

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 housing + coupling) provides great versatility to suit a broad selection of applications and provides higher efficiency compared to the compact collection XC, where the emphasis is on space effectiveness.
Series H offers the same features since series X with an added plus: a spur equipment pre-stage at the insight end provides higher overall performance and a broader selection of ratios than the X series.
Frame sizes 110 and 90 include 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 comes as standard.
