Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be little, but it’s hard enough to take care of demanding power transfer applications. Constructed with machined light weight aluminum housings and hardened metal input and output gears, they’ll deliver a long time of reliable performance.
Obtainable in three standard result 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 equipment box assembly provides proportionally high torque values (1.4 NM at 3,000 RPM) with very low backlash (maximum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque predicated on application. Also speed is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed decrease ratio. Ever-Power has a full line of gearboxes and velocity reducers, and the parts needed to build them, in a wide selection of standard ratios and shaft choices in addition to custom designs.
Helical, bevel, and miter gear boxes offer the options of quickness reducers or acceleration increasers, and could be powered in either path. All Ever-Power worm equipment speed reducers and correct angle drives are manufactured for powerful in a large spectrum of applications. Typically worm gear boxes are not used as swiftness increasers. The situations are molded glass-filled materials making them extremely durable and resistant to corrosive environments. They are offered in a wide range of ratios and are built with right hands or left hands worm gears. The output shafts could be solid or hollow, and load capability is unaffected by path and rotation.
Worm gear speed reducers are made up of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and so are used in mechanical applications which range from conveyors to 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 reaches right into a slot of the driven 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 phrases 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 due to the very smooth operating of the worm equipment combined with the use of cast iron and high precision on component 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 level of our gearbox is usually reduced to an absolute 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 considerably simpler and more compact.The worm gearbox can be 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 well suited for direct suspension for wheels, movable arms 
and other parts rather than needing to build 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 utilized as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited for a wide range of solutions.
Structural Features
The worm-gear reducer is made up 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 effectively under stressed conditions, vibrations or any kind of setback that can’t be avoided during the assembly
The worm-gear is made from 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 high quality, excellent functionality and low noise amounts 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 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 provides like reference size 63 and is born 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 feature 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 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 apparatus reducer had 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 need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this element when the gear reducer result shaft is driven rather than being a driver. Bearing in mind that one of the features of this worm-gear reducer is the fact that cannot be axle-powered by the output shaft (irreversibility), it is almost unattainable to meet up total irreversibility conditions, due to external elements such as for example vibrations, etc. For this reason, when the application form requires total irreversibility, it really is advisable to make use of external brakes with enough power to avoid slipping.
It could be said that the conditions under which irreversibility can happen are as follows:
• Efficiency < 0,55 (find table of technical features).
Maintenance
This sort of gear reducer will get a permanent lubrication, so that it really does not need any kind of maintenance.
Lubrication
The lubrication of this gear reducer type is continuous and comes as standard, with top quality refined oil which includes 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 isn’t needed.
