Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be tiny, but it’s hard enough to take care of demanding vitality transfer applications. Designed with machined aluminum housings and hardened steel input and result gears, they’ll deliver a long time of reliable performance.
Obtainable in three standard output ratios and with two output shaft diameter options, it’s simple to find the EP correct miniature gearbox to your requirements. Each RW style worm gear box assembly provides proportionally large torque values (1.4 NM at 3,000 RPM) with suprisingly low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque predicated on application. Also acceleration is increased or decreased compared index G – Equipment BOXES – on blue – smallto the speed reduction ratio. EP has a full type of gearboxes and rate reducers, and the elements had a need to build them, in a wide variety of regular ratios and shaft choices along with custom designs.
Helical, bevel, and miter equipment boxes offer the options of rate reducers or quickness increasers, and may be driven in either path. All EP worm gear speed reducers and correct angle drives are manufactured for powerful in a large spectral range of applications. Commonly worm gear boxes aren’t used as acceleration increasers. The situations are molded glass-filled materials making them extremely rugged and resilient to corrosive environments. They are offered in an array of ratios and are equipped with right hands or left hands worm gears. The output shafts may be solid or hollow, and load capacity is unaffected by path and rotation.
Worm gear rate reducers are comprised of a screw (the worm) that drives a steering wheel (helical gear) or single enveloping wheel and are found in mechanical applications ranging from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary movement into intermittent rotary movement. The rotating drive steering wheel includes a pin that gets to right into a slot of the driven steering wheel advancing it by one stage and a blocking disk that locks the powered wheel constantly in place between steps.
Compact design
Compact design is among the key words of the typical gearboxes of the BJ-Series. Further optimisation can be achieved by using adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is due to the very smooth running of the worm equipment combined with the use of cast iron and large precision on element manufacturing and assembly. Regarding the our accuracy gearboxes, we take extra treatment of any sound that can be interpreted as a murmur from the apparatus. Therefore the general noise degree of our gearbox is certainly reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This frequently proves to become a decisive advantage producing the incorporation of the gearbox significantly simpler and more compact.The worm gearbox is an angle gear. This is an edge for incorporation into constructions.
Strong bearings in solid housing
The output shaft of the BJ worm gearbox is quite firmly embedded in the gear house and is well suited for immediate suspension for wheels, movable arms and other parts rather than having to build a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes provides a self-locking impact, which in many situations can be utilized as brake or as extra protection. Likewise spindle gearboxes with a trapezoidal spindle happen to be self-locking, making them perfect for a wide variety of solutions.
Structural Features
The worm-gear reducer is made up of three main parts: housing, worm-gear and wheel.
The carcasses are made of GG-25 cast-iron, and are available for all kinds of gear-reducer. This make them perform efficiently under stressed circumstances, vibrations or any kind of setback that can’t be avoided through the assembly
The worm-gear is constructed of hardened and quench-hardened steel, with ground- on teeth sides, and the crowns made of DIN (GZ-CuSn 12 Ni2) centricast bronze, melted on steel. Due to the mechanical work of these two parts having high quality, excellent efficiency and low noises amounts have been achived.
The output shaft is hollow, although it is possible to adapt a solid shaft.
The oil seals manufactured from NITRILE BUTADIENE, according to DIN 3760, high quality bearings, an EPOXY- impregnated finish ( 2 components), and grey-coloured SINGLE LAYER ENAMEL finish ( 2 components) ( RAL 7672), provide the most competitive gear reducer out there.
Size 63
In the size 62 of the MF series, worm-gear reducers, the output hollow shaft of diameter 30 has been included, that substitutes to the output hollow shaft with diameter 25, from size 62. This variant has like reference size 63 and is born like answer to the demand of our costumers since, upon mounting better bearings in the result, bears greater axial loads that its analogous one in the MF-62 series. The others of technical characteristic are similar to the its analogous in the size 62.
Assembly Position
In order to set up a gear reducer and also to make it work efficiently, the following instructions must be taken into account:
It must be fixed on a flat surface in order to avoid either vibrations or tensions.
If undistributed loads or continued start-ups are foreseen, it is suggested to insert compensating couplings, connectors, torque limiters etc…
If the apparatus reducer needed to be painted, the essential oil seals must be covered to prevent them from drying and losing their seal.
The device work of the fittings setup in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this component when the apparatus reducer output shaft is driven rather than being a driver. Considering that among the top features of this worm-gear reducer may be the fact that can’t be axle-powered by the result shaft (irreversibility), it is almost impossible to meet total irreversibility conditions, because of external factors such as vibrations, etc. For this reason, when the application needs total irreversibility, it really is advisable to make use of exterior brakes with enough power to avoid slipping.
It could be said that the circumstances under which irreversibility can happen are as follows:
• Efficiency < 0,55 (find table of technical features).
Maintenance
This type of gear reducer will get a permanent lubrication, so that it does not need any type of maintenance.
Lubrication
The lubrication of this gear reducer type is constant and comes as standard, with top quality refined oil which includes antirust and antiwear products with Fe, Cu and alloy protectors that has quality level CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; because of this its maintenance isn’t needed.
