Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be small, but it’s difficult enough to take care of demanding electricity transfer applications. Constructed with machined aluminium 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 right miniature gearbox to your requirements. Each RW style worm gear package assembly provides proportionally great torque ideals (1.4 NM at 3,000 RPM) with suprisingly low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque predicated on application. Also acceleration is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed decrease ratio. EP has a full type of gearboxes and speed reducers, and the components needed to build them, in a wide variety of standard ratios and shaft choices as well as custom designs.
Helical, bevel, and miter gear boxes offer the options of acceleration reducers or rate increasers, and could be driven in either path. All EP worm gear speed reducers and right angle drives are manufactured for high performance in a large spectral range of applications. Commonly worm gear boxes aren’t used as quickness increasers. The situations are molded glass-filled materials making them extremely durable and tolerant to corrosive environments. They are offered in a wide variety of ratios and are built with right hands or left hands worm gears. The result shafts may be solid or hollow, and load capability is unaffected by direction and rotation.
Worm gear speed reducers are made up of a good screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and so are used in mechanical applications ranging from conveyors to workout devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary movement into intermittent rotary motion. The rotating drive steering wheel has a pin that reaches right into a slot of the powered steering wheel advancing it by one stage and a blocking disk that locks the driven wheel constantly in place between steps.
Compact design
Compact design is among the key phrases of the standard 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 due to the very smooth running of the worm gear combined with the use of cast iron and high precision on component manufacturing and assembly. In connection with our precision gearboxes, we consider extra treatment of any sound that can be interpreted as a murmur from the gear. Therefore the general noise level of our gearbox is definitely reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This often proves to be a decisive advantage making the incorporation of the gearbox considerably simpler and more compact.The worm gearbox can be an angle gear. This is an edge for incorporation into constructions.
Solid bearings in solid housing
The output shaft of the BJ worm gearbox is quite firmly embedded in the apparatus house and is ideal for direct suspension for wheels, movable arms and other parts rather than having to create a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes provides a self-locking effect, which in many situations can be used as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them perfect for an array of solutions.
Structural Features
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are made of GG-25 cast-iron, and so are available for all sorts of gear-reducer. This make them perform efficiently under stressed circumstances, vibrations or any kind of setback that can’t be avoided during the assembly
The worm-gear is made from 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 high quality, excellent performance and low sound levels have been achived.
The output shaft is hollow, though 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), supply the most competitive gear reducer in the marketplace.
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 exists like response to the request of our costumers since, upon mounting higher bearings in the result, 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 to make it work efficiently, the following instructions must be taken into account:
It must 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 gear reducer had to be painted, the oil seals must be covered to prevent them from drying and losing their seal.
The machine work of the fittings setup in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this aspect when the gear reducer result shaft is driven instead of being a driver. Bearing in mind that one of the top features of this worm-gear reducer is the fact that cannot be axle-driven by the result shaft (irreversibility), it really is almost unattainable to meet up total irreversibility conditions, because of external factors such as for example vibrations, etc. This is why, when the application needs total irreversibility, it is advisable to make use of external brakes with enough power to avoid slipping.
It could be said that the circumstances under which irreversibility can occur are the following:
• Efficiency < 0,55 (find 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 the gear reducer type is constant and comes as standard, with high quality refined oil which includes antirust and antiwear products with Fe, Cu and alloy protectors which has quality level CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; because of this its maintenance is not needed.
