Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be small, but it’s tough enough to take care of demanding power transfer applications. Constructed with machined aluminium housings and hardened steel input and result gears, they’ll deliver many years of reliable performance.
Available in three standard result 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 huge torque ideals (1.4 NM at 3,000 RPM) with very low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque based on application. Also swiftness is increased or decreased compared index G – Equipment BOXES – on blue – smallto the speed reduction ratio. EP has a full line of gearboxes and speed reducers, and the parts needed to build them, in a wide variety of regular ratios and shaft options in addition to custom designs.
Helical, bevel, and miter gear boxes provide options of velocity reducers or quickness increasers, and may be driven in either direction. All EP worm gear speed reducers and right angle drives are produced for powerful in a large spectrum of applications. Typically worm gear boxes are not used as acceleration increasers. The situations are molded glass-filled materials making them extremely durable and tolerant to corrosive environments. They are offered in an array of ratios and are built with right hands or left hand worm gears. The output shafts may be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear quickness reducers are made up 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 usually used to transform continuous rotary motion into intermittent rotary movement. The rotating drive steering wheel includes a pin that reaches right into a slot of the driven wheel advancing it by one stage 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 typical gearboxes of the BJ-Series. Further optimisation can be achieved through the use of adapted gearboxes or particular gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth running of the worm equipment combined with the use of cast iron and substantial precision on component manufacturing and assembly. In connection with our accuracy gearboxes, we take extra care of any sound which can be interpreted as a murmur from the gear. Therefore the general noise degree of our gearbox can be reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This frequently proves to become a decisive advantage producing the incorporation of the gearbox significantly simpler and more compact.The worm gearbox can be an angle gear. This is often 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 apparatus house and is ideal for immediate suspension for wheels, movable arms and other parts rather than having to build a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes will provide a self-locking effect, which in 
many situations can be used as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle happen to be self-locking, making them ideal 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 so are available for all kinds of gear-reducer. This make sure they are perform effectively under stressed conditions, vibrations or any kind of setback that can’t 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. Because of the mechanical work of these two parts having high quality, excellent performance and low noises levels have been achived.
The output shaft is hollow, though it is possible to adapt a solid shaft.
The oil seals made of 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 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 better axial loads that its analogous one in the MF-62 series. The rest of technical feature are identical to the its analogous in the size 62.
Assembly Position
In order to set up a gear reducer and also to make it happen efficiently, the next 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 recommended to insert compensating couplings, connectors, torque limiters etc…
If the apparatus reducer had to be painted, the oil seals should be covered to avoid them from drying and losing their seal.
The device 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 aspect when the gear reducer output shaft is driven instead of being a driver. Bearing in mind that among the top features of this worm-equipment reducer may be the fact that cannot be axle-driven by the output shaft (irreversibility), it really is almost difficult to meet up total irreversibility conditions, because of external elements such as for example vibrations, etc. That is why, when the application requires total irreversibility, it is advisable to utilize exterior brakes with enough power to avoid slipping.
It may be said that the conditions under which irreversibility can happen are the following:
• Efficiency < 0,55 (observe table of specialized features).
Maintenance
This type of gear reducer will get a permanent lubrication, so it will not need any type 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 is not needed.
