Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be tiny, but it’s hard enough to handle demanding vitality transfer applications. Designed with machined light weight aluminum housings and hardened steel input and result gears, they’ll deliver many years of reliable performance.
Available in three standard result ratios and with several output shaft diameter options, it’s simple to find the EP correct miniature gearbox for your needs. Each RW model worm gear container assembly provides proportionally huge torque ideals (1.4 NM at 3,000 RPM) with suprisingly low backlash (maximum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque predicated on application. Also speed is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed reduction ratio. EP has a full line of gearboxes and acceleration reducers, and the elements had a need to build them, in an array of standard ratios and shaft choices as well as custom designs.
Helical, bevel, and miter equipment boxes offer the options of acceleration reducers or velocity increasers, and may be powered in either path. All EP worm equipment speed reducers and right angle drives are manufactured for high performance in a large spectrum of applications. Typically worm gear boxes aren’t used as swiftness 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 hand worm gears. The result shafts may be sturdy or hollow, and load capacity is unaffected by direction and rotation.
Worm gear rate reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or solitary enveloping wheel and are used in mechanical applications which range from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary movement into intermittent rotary movement. The rotating drive wheel includes a pin that reaches right into a slot of the powered wheel advancing it by one step and a blocking disc that locks the driven wheel in position between steps.
Compact design
Compact design is one of the key phrases of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished through the use of adapted gearboxes or particular 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 huge precision on component manufacturing and assembly. In connection with our accuracy gearboxes, we consider extra care of any sound which can be interpreted as a murmur from the apparatus. Therefore the general noise degree of our gearbox is usually reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This generally proves to become a decisive advantage making the incorporation of the gearbox considerably simpler and more compact.The worm gearbox can be an angle gear. This is often an advantage for incorporation into constructions.
Strong bearings in solid housing
The output shaft of the BJ worm gearbox is very firmly embedded in the apparatus house and is perfect for immediate suspension for wheels, movable arms and other parts rather than needing to create a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes will provide a self-locking impact, which in many situations can be used as brake or as extra protection. As well spindle gearboxes with a trapezoidal spindle are self-locking, making them perfect for a wide range 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 sorts of gear-reducer. This make them perform efficiently under stressed conditions, vibrations or any kind of setback that cannot be avoided through 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 performance and low sound levels have been achived.
The output shaft is hollow, though it can be done to adapt a solid shaft.
The oil seals made of 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), provide the best gear reducer available.
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 response to the demand of our costumers since, after mounting better bearings in the output, bears greater axial loads that its analogous one in the MF-62 series. The rest of technical feature are similar to the its analogous in the size 62.
Assembly Position
In order to create a gear reducer and also to make it happen efficiently, the following instructions must be taken into account:
It should be fixed on a flat surface 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 machine work of the fittings create in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to pay attention to this component when the apparatus reducer result shaft is driven rather than being a driver. Considering that among the features of this worm-gear reducer may be the fact that cannot be axle-driven by the result shaft (irreversibility), it is almost unattainable to meet total irreversibility conditions, because of external factors such as for example vibrations, etc. That is why, when the application needs total irreversibility, it is advisable to utilize external brakes with enough capacity to avoid slipping.
It could be said that the conditions under which irreversibility can happen are as follows:
• Efficiency < 0,55 (discover table of specialized features).
Maintenance
This kind of gear reducer is provided with a permanent lubrication, so it will 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; for that reason its maintenance isn’t needed.
