Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be small, but it’s tough enough to take care of demanding vitality transfer applications. Constructed 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 two output shaft size options, it’s simple to find the EP correct miniature gearbox to 
your requirements. Each RW model worm gear container assembly provides proportionally huge torque values (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 velocity is increased or decreased in proportion index G – Equipment BOXES – on blue – smallto the speed decrease ratio. EP includes a full type of gearboxes and swiftness reducers, and the parts had a need to build them, in an array of standard ratios and shaft choices along with custom designs.
Helical, bevel, and miter equipment boxes provide options of swiftness reducers or acceleration increasers, and may be powered in either direction. All EP worm gear speed reducers and correct angle drives are produced for high performance in a large spectral range of applications. Commonly worm gear boxes aren’t used as speed 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 equipped with right hand or left hand worm gears. The output shafts may be stable or hollow, and load capacity is unaffected by path and rotation.
Worm gear swiftness reducers are made up of a good screw (the worm) that drives a steering wheel (helical gear) or solitary enveloping wheel and are used in mechanical applications ranging 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 has a pin that gets to right into a slot of the powered wheel advancing it by one step and a blocking disc that locks the driven wheel constantly in place between steps.
Compact design
Compact design is among the key terms of the standard gearboxes of the BJ-Series. Further optimisation can be achieved by using adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth working of the worm equipment combined with the utilization of cast iron and huge precision on element manufacturing and assembly. Regarding the our precision gearboxes, we take extra treatment of any sound that can be interpreted as a murmur from the apparatus. Therefore the general noise level of our gearbox is 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 become a decisive advantage making the incorporation of the gearbox substantially simpler and more compact.The worm gearbox is an angle gear. This is 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 needing to create a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes will provide a self-locking effect, which in many circumstances can be used as brake or as extra security. As well spindle gearboxes with a trapezoidal spindle are self-locking, making them perfect for a wide selection of solutions.
Structural Features
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are constructed with GG-25 cast-iron, and so are available for all kinds of gear-reducer. This make sure they are perform effectively under stressed circumstances, vibrations or any kind of setback that can’t be avoided during the assembly
The worm-gear is constructed 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. Because of the mechanical work of the two parts having top quality, excellent efficiency and low noise levels have been achived.
The output shaft is hollow, although 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 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 provides like reference size 63 and is born like answer to the ask for of our costumers since, upon mounting better bearings in the output, bears better axial loads that its analogous one in the MF-62 series. The others of technical characteristic are identical to the its analogous in the size 62.
Assembly Position
In order to setup a gear reducer and to make it work efficiently, the next instructions must be considered:
It must be fixed on a flat surface to avoid either vibrations or perhaps 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 needed to be painted, the oil seals must be covered to prevent them from drying and losing their seal.
The machine work of the fittings set up in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this element when the apparatus reducer result 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-powered by the result shaft (irreversibility), it really is almost unattainable to meet total irreversibility conditions, due to external elements such as for example vibrations, etc. For this reason, when the application needs total irreversibility, it really is advisable to make use of exterior brakes with enough capacity to avoid slipping.
It may be said that the circumstances under which irreversibility can occur are the following:
• Efficiency < 0,55 (see table of technical features).
Maintenance
This type of gear reducer is provided with 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.
