Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be little, but it’s difficult enough to handle demanding power transfer applications. Designed with machined aluminium 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 result shaft diameter options, it’s easy to find the Ever-Power correct miniature gearbox for your needs. Each RW model worm equipment box 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 based on application. Also quickness is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed reduction ratio. Ever-Power includes a full line of gearboxes and swiftness reducers, and the parts needed to build them, in a wide range of regular ratios and shaft options as well as custom designs.
Helical, bevel, and miter gear boxes provide options of velocity reducers or velocity increasers, and may be powered in either direction. All Ever-Power worm equipment speed reducers and correct angle drives are manufactured for powerful in a large spectrum of applications. Typically worm equipment boxes are not used as acceleration increasers. The cases are molded glass-filled material making them extremely rugged and resistant to corrosive conditions. They are offered in an array of ratios and are equipped with right hands or left hands worm gears. The result shafts may be solid or hollow, and load capacity 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 single enveloping wheel and are used in mechanical applications which range 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 includes a pin that gets to into a slot of the powered wheel advancing it by one stage and a blocking disc that locks the powered wheel constantly in place between steps.
Compact design
Compact design is one of the key words of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or special 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 component 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 level of our gearbox can be reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This frequently proves to be a decisive advantage making the incorporation of the gearbox substantially simpler and more compact.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 very firmly embedded in the gear house and is well suited for direct suspension for wheels, movable arms and other areas rather than having to create a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes will provide a self-locking impact, which in many situations can be utilized as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them ideal for an array of solutions.
Structural Features
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are made of 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 kind of setback that can’t be avoided during 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 the two parts having top quality, excellent functionality and low sound amounts have been achived.
The output shaft is hollow, although it can be done to adapt a good shaft.
The oil seals made of NITRILE BUTADIENE, according to DIN 3760, top 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 exists like answer to the ask for of our costumers since, upon mounting higher bearings in the output, bears better axial loads that its analogous one in the MF-62 series. The others of technical characteristic are similar to the its analogous in the size 62.
Assembly Position
In order to create a gear reducer and to make it work efficiently, the next instructions must be considered:
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 recommended to insert compensating couplings, connectors, torque limiters etc…
If the gear reducer needed to be painted, the oil seals should be covered to prevent them from drying and losing their seal.
The device work of the fittings set up in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this factor when the apparatus reducer output shaft is driven rather than being a driver. Bearing in mind that one of the features of this worm-gear reducer may be the fact that cannot be axle-driven by the output shaft (irreversibility), it is almost unattainable to meet up total irreversibility conditions, due to external factors such as for example vibrations, etc. This is why, when the application needs total irreversibility, it is advisable to make use of exterior brakes with enough capacity to avoid slipping.
It may be said that the conditions under which irreversibility can occur are the following:
• Efficiency < 0,55 (find table of technical features).
Maintenance
This sort of gear reducer will get a permanent lubrication, so it really does not need any type 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 level of quality CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; because of this its maintenance is not needed.
