Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be little, but it’s tough enough to handle demanding power transfer applications. Constructed with machined light weight aluminum housings and hardened metal input and output gears, they’ll deliver many years of reliable performance.
Available in three standard result ratios and with two output shaft diameter options, it’s easy to find the Ever-Power correct miniature gearbox for your needs. Each RW model worm gear container assembly provides proportionally high torque values (1.4 NM at 3,000 RPM) with suprisingly low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque predicated on application. Also rate is increased or reduced in proportion index G – GEAR BOXES – on blue – smallto the speed decrease ratio. Ever-Power has a full type of gearboxes and quickness reducers, and the parts had a need to build them, in an array of standard ratios and shaft options along with custom designs.
Helical, bevel, and miter gear boxes offer the options of swiftness reducers or speed increasers, and may be powered in either direction. All Ever-Power worm equipment speed reducers and right angle drives are manufactured for powerful in a large spectrum of applications. Typically worm equipment boxes aren’t used as quickness increasers. The situations are molded glass-filled material 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 could be solid or hollow, and load capacity is unaffected by path and rotation.
Worm gear rate reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and so are used in mechanical applications ranging from conveyors to workout devices to robots.
Geneva mechanisms and assemblies are typically 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 wheel advancing it by one stage and a blocking disc that locks the powered wheel in position between steps.
Compact design
Compact design is among the key terms of the typical gearboxes of the BJ-Series. Further optimisation may be accomplished through the use of adapted gearboxes or particular gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth operating of the worm gear combined with the use of cast iron and high precision on element 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 degree of our gearbox is definitely reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This often proves to be a decisive advantage producing the incorporation of the gearbox considerably simpler and smaller sized.The worm gearbox is an angle gear. This is an advantage 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 immediate suspension for wheels, movable arms and other parts rather than needing 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 circumstances can be used as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them ideal for a wide variety 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 are available for all sorts of gear-reducer. This make them perform efficiently under stressed circumstances, vibrations or any type of setback that cannot be avoided during the assembly
The worm-gear is constructed 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 functionality and low noise levels have been achived.
The output shaft is hollow, though it can be done 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 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 offers like reference size 63 and is born like answer to the demand of our costumers since, upon mounting greater bearings in the output, 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 also to make it happen efficiently, the following instructions must be taken into account:
It should be fixed on a flat surface in order to avoid either vibrations or worm gear box assembly 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 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 pay attention to this element when the apparatus reducer result shaft is driven rather than being a driver. Bearing in mind that one of the top features of this worm-equipment reducer may be the fact that cannot be axle-powered by the output shaft (irreversibility), it really is almost difficult to meet total irreversibility conditions, because of external elements such as for example vibrations, etc. For this reason, when the application requires total irreversibility, it is advisable to make use of external brakes with enough capacity to avoid slipping.
It could be said that the circumstances under which irreversibility can happen are the following:
• Efficiency < 0,55 (see table of technical features).
Maintenance
This kind 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 constant and comes as standard, with high quality refined oil which includes 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; for that reason its maintenance isn’t needed.
