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 light weight aluminum housings and hardened steel input and output gears, they’ll deliver a long time of reliable performance.
Obtainable in three standard output ratios and with several output shaft size options, it’s easy to find the EP correct miniature gearbox to your requirements. Each RW style worm gear package assembly provides proportionally substantial torque values (1.4 NM at 3,000 RPM) with suprisingly low backlash (maximum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque predicated on application. Also swiftness is increased or decreased compared index G – GEAR BOXES – on blue – smallto the speed reduction ratio. EP has a full line of gearboxes and rate reducers, and the elements needed to build them, in an array of standard ratios and shaft options and also custom designs.
Helical, bevel, and miter equipment boxes offer the options of acceleration reducers or speed increasers, and may be driven in either direction. All EP worm equipment speed reducers and correct angle drives are produced for powerful in a large spectral range of applications. Commonly worm gear boxes are not used as acceleration increasers. The cases are molded glass-filled material making them extremely durable 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 sound or hollow, and load capability is unaffected by direction and rotation.
Worm gear swiftness reducers are made up of a screw (the worm) that drives a wheel (helical gear) or solitary enveloping wheel and so are found in mechanical applications ranging from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary motion into intermittent rotary movement. The rotating drive steering 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 in position between steps.
Compact design
Compact design is one of the key phrases of the standard gearboxes of the BJ-Series. Further optimisation can be achieved by using adapted gearboxes or unique gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is because of the very smooth operating of the worm gear combined with the use of cast iron and great precision on element manufacturing and assembly. In connection with our precision gearboxes, we consider extra care of any sound that can be interpreted as a murmur from the apparatus. So the general noise degree of our gearbox is reduced to an absolute 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 smaller sized.The worm gearbox can be 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 very firmly embedded in the gear house and is perfect for immediate suspension for wheels, movable arms and other areas 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 security. As well spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited for an array 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 sure they are perform efficiently under stressed circumstances, vibrations or any type 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 made of DIN (GZ-CuSn 12 Ni2) centricast bronze, melted on steel. Due to the mechanical work of these two parts having top quality, excellent performance and low sound amounts have been achived.
The output shaft is hollow, although it can be done 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 best 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 has like reference size 63 and exists like response to the request of our costumers since, upon mounting better bearings in the result, bears better axial loads that its analogous one in the MF-62 series. The rest of technical characteristic are identical to the its analogous in the size 62.
Assembly Position
In order to set up a gear reducer and 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 recommended to insert 
compensating couplings, connectors, torque limiters etc…
If the gear reducer had 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 need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to pay attention to this factor when the gear reducer result shaft is driven instead of being a driver. Bearing in mind that one of the features of this worm-equipment reducer may be the fact that can’t be axle-powered by the result shaft (irreversibility), it is almost unattainable to meet total irreversibility conditions, because of external factors such as vibrations, etc. This is why, when the application requires total irreversibility, it is advisable to utilize exterior brakes with enough capacity to avoid slipping.
It may be said that the circumstances under which irreversibility can happen are as follows:
• Efficiency < 0,55 (observe table of specialized features).
Maintenance
This sort of gear reducer will get a permanent lubrication, so it does 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 that 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.
