Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be little, but it’s hard enough to take care of demanding vitality transfer applications. Designed with machined aluminum housings and hardened metal input and result gears, they’ll deliver many years of reliable performance.
Obtainable in three standard output ratios and with two output shaft size options, it’s simple to find the EP correct miniature gearbox for your needs. Each RW style worm gear package assembly provides proportionally high 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 speed is increased or reduced compared index G – Equipment BOXES – on blue – smallto the speed decrease ratio. EP includes a full type of gearboxes and speed reducers, and the parts needed to build them, in a wide range of regular ratios and shaft choices in addition to custom designs.
Helical, bevel, and miter equipment boxes provide options of quickness reducers or speed increasers, and could be powered in either path. All EP worm equipment speed reducers and right angle drives are manufactured for high performance in a large spectral range of applications. Typically worm gear boxes aren’t used as rate increasers. The situations are molded glass-filled materials making them extremely tough and resilient to corrosive conditions. They can be found in a wide selection of ratios and are equipped with right hand or left hand worm gears. The output shafts may be sturdy or hollow, and load capacity is unaffected by path and rotation.
Worm gear quickness reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and so are used in mechanical applications ranging from conveyors to exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary movement into intermittent rotary movement. The rotating drive wheel has a pin that reaches into a slot of the powered wheel advancing it by one stage and a blocking disk that locks the powered wheel in position between steps.
Compact design
Compact design is among the key terms of the typical gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or particular gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth operating of the worm gear combined with the usage of cast iron and huge precision on component manufacturing and assembly. In connection with our accuracy gearboxes, we take extra care of any sound that can be interpreted as a murmur from the gear. Therefore the general noise degree of our gearbox is reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This often proves to become a decisive advantage making the incorporation of the gearbox significantly simpler and smaller sized.The worm gearbox is an angle gear. This is often an advantage for incorporation into constructions.
Solid bearings in solid housing
The output shaft of the BJ worm gearbox is very firmly embedded in the gear house and is perfect for direct suspension for wheels, movable arms and other areas rather than needing to create a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes provides a self-locking effect, which in many circumstances can be utilized as brake or as extra protection. As well spindle gearboxes with a trapezoidal spindle happen to be self-locking, making them perfect for a wide selection of solutions.
Structural Features
The worm-gear reducer is made up of three main parts: housing, worm-gear and wheel.
The carcasses are made from GG-25 cast-iron, and so are available for all types of gear-reducer. This make sure they are perform efficiently under stressed conditions, vibrations or any kind of setback that cannot be avoided during the assembly
The worm-gear is made of hardened and quench-hardened steel, with ground- on teeth sides, and the crowns manufactured from DIN (GZ-CuSn 12 Ni2) centricast bronze, melted on steel. Due to the mechanical work of the two parts having top quality, excellent functionality and low noise levels have been achived.
The output shaft is hollow, although it is possible to adapt a good shaft.
The oil seals manufactured from NITRILE BUTADIENE, according to DIN 3760, top quality bearings, an EPOXY- impregnated finish ( 2 components), and grey-coloured SINGLE LAYER ENAMEL finish ( 2 components) ( RAL 7672), supply the most competitive gear reducer on the market.
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 offers like reference size 63 and is born like answer to the ask for of our costumers since, after mounting greater bearings in the output, 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 create a gear reducer and to make it happen efficiently, the following instructions must be taken into account:
It must be fixed on a set surface to avoid either vibrations or tensions.
If undistributed loads or continued start-ups are foreseen, it is recommended to insert compensating couplings, connectors, torque limiters etc…
If the apparatus reducer needed to be painted, the essential oil seals must be covered to avoid 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 point when the apparatus reducer result shaft is driven instead of being a driver. Bearing in mind that among the top features of this worm-gear reducer may be the fact that can’t be axle-driven by the result shaft (irreversibility), it is almost difficult to meet up total irreversibility conditions, because of external elements such as vibrations, etc. This is why, when the application requires total irreversibility, it is advisable to make use of external brakes with enough capacity to avoid slipping.
It may be said that the circumstances under which irreversibility can occur are the following:
• Efficiency < 0,55 (observe table of technical features).
Maintenance
This sort of gear reducer is provided with a permanent lubrication, so that it will not need any kind of maintenance.
Lubrication
The lubrication of the gear reducer type is continuous and comes as standard, with top quality refined oil which has antirust and antiwear products with Fe, Cu and alloy protectors which has level of quality CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; for that reason its maintenance isn’t needed.
