Ever-Power has been designing and manufacturing reliable, high performance gearboxes for over 20 years. RW Series miniature right angle gearboxes provide high torque values with very low backlash in incredibly compact frames. Three gear ratios are available to meet up the requirements of your specific application.

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

Mechanical drives take supplied torque and could increase or reduce that torque based on application. Also swiftness is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed decrease ratio. Ever-Power has a full line of gearboxes and velocity reducers, and the elements had a need to build them, in an array of standard ratios and shaft options as well as custom designs.
Helical, bevel, and miter gear boxes offer the options of velocity reducers or swiftness increasers, and could be driven in either direction. All Ever-Power worm equipment speed reducers and correct angle drives are manufactured for high performance in a large spectral range of applications. Typically worm gear boxes are not used as velocity increasers. The cases are molded glass-filled materials making them extremely tough and resistant to corrosive environments. They are offered in an array of ratios and are equipped with right hands or left hand worm gears. The result shafts could be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear quickness reducers are made up of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and so 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 motion. The rotating drive wheel has a pin that reaches right into a slot of the powered wheel advancing it by one stage and a blocking disc that locks the powered wheel in position between steps.
Compact design
Compact design is one of the key words of the typical gearboxes of the BJ-Series. Further optimisation may be accomplished through the use of adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is because of the very smooth working of the worm gear combined with the use of cast iron and high precision on element manufacturing and assembly. Regarding the our precision gearboxes, we take extra treatment of any sound that can be interpreted as a murmur from the gear. Therefore the general noise level of our gearbox can be 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 become a decisive advantage producing 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.
Strong 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 having to build a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes provides a self-locking impact, which in many situations can be used 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 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 them perform efficiently under stressed conditions, vibrations or any type of setback that can’t be avoided through 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. Because of the mechanical work of the two parts having high quality, excellent performance and low sound 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, 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 has like reference size 63 and is born like response to the request of our costumers since, upon mounting higher bearings in the result, bears greater axial loads that its analogous one in the MF-62 series. The rest of technical feature are identical to the its analogous in the size 62.
Assembly Position
In order to setup a gear reducer and to make it happen efficiently, the next instructions must be taken into account:
It should 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 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 setup in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this element when the apparatus reducer output shaft is driven rather than being a driver. Bearing in mind that among the features of this worm-gear reducer may be the fact that can’t be axle-powered by the output shaft (irreversibility), it is almost impossible to meet total irreversibility conditions, due to external elements such as vibrations, etc. This is why, when the application needs total irreversibility, it really is advisable to make use of external brakes with enough power to avoid slipping.
It may be said that the conditions under which irreversibility can happen are the following:
• Efficiency < 0,55 (discover table of technical features).
Maintenance
This kind of gear reducer is provided with a permanent lubrication, so it does not need any kind of maintenance.
Lubrication
The lubrication of the 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 which has level of quality CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; because of this its maintenance isn’t needed.
