Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be tiny, but it’s tough enough to take care of demanding electricity transfer applications. Constructed with machined aluminium housings and hardened steel input and output gears, they’ll deliver many years of reliable performance.
Available in three standard output ratios and with several output shaft diameter options, it’s easy to find the EP correct miniature gearbox for your needs. Each RW unit worm gear box assembly provides proportionally great torque values (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 based on application. Also swiftness is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed reduction ratio. EP includes a full line of gearboxes and rate reducers, and the elements needed to build them, in an array of standard ratios and shaft choices along with custom designs.
Helical, bevel, and miter gear boxes provide options of quickness reducers or speed increasers, and could be driven in either path. All EP worm equipment speed reducers and correct angle drives are produced for high performance in a large spectral range of applications. Typically worm gear boxes aren’t used as speed increasers. The situations are molded glass-filled materials making them extremely rugged and tolerant to corrosive environments. They can be found in a wide selection of ratios and are built with right hands or left hands worm gears. The result shafts may be sturdy or hollow, and load capability is unaffected by direction and rotation.
Worm gear acceleration reducers are comprised of a good screw (the worm) that drives a steering wheel (helical gear) or one enveloping wheel and so are used in mechanical applications which range from conveyors to exercise devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary movement into intermittent rotary movement. The rotating drive 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 driven wheel constantly in place between steps.
Compact design
Compact design is one of the key terms of the typical gearboxes of the BJ-Series. Further optimisation can be achieved through the use of adapted gearboxes or unique gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is due to the very smooth working of the worm equipment combined with the use of cast iron and huge precision on element 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 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 quite often proves to become a decisive advantage making the incorporation of the gearbox substantially simpler and smaller sized.The worm gearbox is an angle gear. This is an advantage 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 ideal for direct suspension for wheels, movable arms and other parts rather than needing to create a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes will provide a self-locking impact, which in many circumstances can be utilized as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle happen to be 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 types of gear-reducer. This make them perform effectively under stressed circumstances, 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. Because of the mechanical work of these two parts having top quality, excellent efficiency and low noise amounts have been achived.
The output shaft is hollow, although it can be done to adapt a good 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 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 has like reference size 63 and exists like answer to the ask for of our costumers since, upon mounting higher bearings in the result, 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 setup a gear reducer and to make it happen efficiently, the following instructions must be considered:
It must be fixed on a set surface in order to avoid either vibrations or perhaps 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 device work of the fittings set up in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this point when the gear reducer output shaft is driven instead of being a driver. Bearing in mind that among the features of this worm-equipment reducer may be the fact that cannot be axle-driven by the result shaft (irreversibility), it is almost impossible to meet up total irreversibility conditions, due to external factors such as vibrations, etc. That is why, when the application needs 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 occur are as follows:
• Efficiency < 0,55 (discover table of technical features).
Maintenance
This type of gear reducer is provided with a permanent lubrication, so that it does not need any type of maintenance.
Lubrication
The lubrication of this gear reducer type is continuous and comes as standard, with top quality refined oil which includes 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; because of this its maintenance isn’t needed.
