Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be little, but it’s challenging enough to take care of demanding electric power transfer applications. Designed 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 easy to find the EP right miniature gearbox to your requirements. Each RW unit worm gear package assembly provides proportionally substantial torque ideals (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 rate is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed reduction ratio. EP has a full line of gearboxes and speed reducers, and the elements had a need to build them, in a wide selection of regular ratios and shaft choices and also custom designs.
Helical, bevel, and miter equipment boxes provide options of velocity reducers or acceleration increasers, and may be powered in either path. All EP worm equipment speed reducers and correct angle drives are manufactured for powerful in a large spectrum of applications. Typically worm gear boxes aren’t used as swiftness increasers. The cases are molded glass-filled materials making them extremely tough and resistant to corrosive environments. They can be found in a wide selection of ratios and are equipped with right hand or left hands worm gears. The output shafts may be sturdy or hollow, and load capability is unaffected by direction and rotation.
Worm gear quickness reducers are comprised of a good screw (the worm) that drives a wheel (helical gear) or one 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 movement into intermittent rotary motion. The rotating drive wheel has a pin that reaches right into a slot of the driven wheel advancing it by one step and a blocking disc that locks the powered 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 by using adapted gearboxes or unique gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth working of the worm equipment combined with the use of cast iron and high precision on element manufacturing and assembly. Regarding the our accuracy gearboxes, we take extra treatment of any sound which can be interpreted as a murmur from the gear. Therefore the general noise degree of our gearbox is certainly reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This generally proves to be a decisive advantage making the incorporation of the gearbox significantly simpler and more compact.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 very firmly embedded in the apparatus house and is well suited for immediate suspension for wheels, movable arms and other parts rather than having to create a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes provides a self-locking effect, which in many circumstances can be used as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle happen to be 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 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 cannot 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 efficiency and low noise levels have been achived.
The output shaft is hollow, though it can be done to adapt a good 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 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 better bearings in the output, bears greater axial loads that its analogous one in the MF-62 series. The rest of technical characteristic are similar to the its analogous in the size 62.
Assembly Position
In order to set up a gear reducer and also to make it work 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 suggested to insert compensating couplings, connectors, torque limiters etc…
If the gear reducer had to be painted, the oil seals should be covered to prevent them from drying and losing their seal.
The device work of the fittings create in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to pay attention to this point 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 may be the fact that cannot be axle-powered by the result shaft (irreversibility), it really is almost impossible to meet total irreversibility conditions, due to external elements such as for example vibrations, etc. This 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 occur are the following:
• Efficiency < 0,55 (observe table of specialized features). Maintenance This type of gear reducer will get a permanent lubrication, so that it does not need any kind of maintenance. Lubrication The lubrication of this gear reducer type is continuous and comes as standard, with high quality refined oil which has antirust and antiwear products with Fe, Cu and alloy protectors that 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.
