Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be little, but it’s tough enough to handle demanding power transfer applications. Designed 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 output ratios and with two result shaft diameter options, it’s easy to find the Ever-Power correct miniature gearbox to your requirements. Each RW model worm gear box assembly provides proportionally high torque ideals (1.4 NM at 3,000 RPM) with very 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. Ever-Power has a full line of gearboxes and acceleration reducers, and the components had a need to build them, in an array of regular ratios and shaft choices along with custom designs.
Helical, bevel, and miter equipment boxes offer the options of rate reducers or acceleration increasers, and could be powered in either direction. All Ever-Power worm gear speed reducers and correct angle drives are produced for high performance in a large spectral range of applications. Typically worm equipment boxes are not used as quickness increasers. The instances are molded glass-filled material making them extremely durable and resistant to corrosive environments. They are offered in a wide range of ratios and are equipped with right hand or left hands worm gears. The output shafts may be solid or hollow, and load capability is unaffected by direction and rotation.
Worm gear rate reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and are found in mechanical applications which range 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 has a pin that gets to right into a slot of the driven wheel advancing it by one step and a blocking disc that locks the driven wheel in position between steps.
Compact design
Compact design is among the key phrases of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or particular gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth working of the worm gear combined with the utilization of cast iron and high precision on component manufacturing and assembly. Regarding the our precision gearboxes, we consider extra care of any sound which can be interpreted as a murmur from the apparatus. So the general noise degree of our gearbox is usually reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This frequently proves to become a decisive advantage making the incorporation of the gearbox substantially simpler and more compact.The worm gearbox can be an angle gear. This is often an edge for incorporation into constructions.
Solid bearings in solid housing
The output shaft of the BJ worm gearbox is very firmly embedded in the gear house and is ideal for immediate suspension for wheels, movable arms and other areas rather than needing to create a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes provides a self-locking effect, which in many circumstances can be used as brake or as extra protection. 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 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 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 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 sound levels have been achived.
The output shaft is hollow, though it is possible 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 out there.
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 ask for of our costumers since, upon mounting better bearings in the result, bears higher 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 set up a gear reducer and also to make it happen efficiently, the next instructions must be taken into account:
It must be fixed on a flat surface in order 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 essential oil seals must be covered to avoid 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 factor when the gear reducer result shaft is driven rather than being a driver. Considering that one of the top features of this worm-equipment reducer may be the fact that cannot be axle-driven by the result shaft (irreversibility), it is almost extremely hard to meet up total irreversibility conditions, due to external elements such as for example vibrations, etc. This is why, when the application form needs total irreversibility, it is advisable to make use of exterior brakes with enough power to avoid slipping.
It may be said that the circumstances under which irreversibility can happen are the following:
• Efficiency < 0,55 (discover table of technical features).
Maintenance
This sort of gear reducer is provided with a permanent lubrication, so that it really does not need any kind of maintenance.
Lubrication
The lubrication of the gear reducer type is constant and comes as standard, with top 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; for that reason its maintenance isn’t needed.
