Ever-Power has been creating and manufacturing reliable, powerful gearboxes for over 20 years. RW Series miniature correct angle gearboxes offer high torque ideals with very low backlash in extremely compact frames. Three equipment ratios are available to meet the requirements of your specific application.

Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be small, but it’s difficult enough to handle 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 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 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 predicated on application. Also quickness is increased or decreased compared index G – GEAR BOXES – on blue – smallto the speed decrease ratio. Ever-Power has a full type of gearboxes and quickness reducers, and the elements had a need to build them, in an array of standard ratios and shaft options and also custom designs.
Helical, bevel, and miter gear boxes offer the options of speed reducers or velocity increasers, and could be driven in either path. All Ever-Power worm gear speed reducers and right angle drives are manufactured for high performance in a large spectral range of applications. Typically worm gear boxes aren’t used as acceleration increasers. The cases are molded glass-filled material making them extremely tough and resistant to corrosive environments. They are offered in a wide variety of ratios and are built with right hand or left hand worm gears. The output shafts could be solid or hollow, and load capacity is unaffected by path and rotation.
Worm gear quickness reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and are used in mechanical applications ranging from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary motion into intermittent rotary motion. The rotating drive wheel includes a pin that gets to 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 among the key words 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 due to the very smooth working of the worm equipment 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 which can be interpreted as a murmur from the apparatus. Therefore the general noise degree 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 each other. This often proves to be a decisive advantage making the incorporation of the gearbox considerably simpler and smaller sized.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 very firmly embedded in the gear house and is well suited for immediate 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 provides a self-locking impact, 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 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 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 these two parts having top quality, excellent functionality and low noise levels have been achived.
The output shaft is hollow, although it can be done to adapt a good 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), provide the best 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 is born like response to the demand of our costumers since, upon mounting greater bearings in the output, bears greater axial loads that its analogous one in the MF-62 series. The others of technical feature are similar to the its analogous in the size 62.
Assembly Position
In order to create a gear reducer and also to make it happen efficiently, the next instructions must be considered:
It must be fixed on a set 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 apparatus reducer needed 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 smart to pay attention to this aspect when the apparatus reducer result shaft is driven instead of being a driver. Considering that among the top features of this worm-equipment reducer is the fact that cannot be axle-powered by the output shaft (irreversibility), it is almost impossible to meet total irreversibility conditions, because of external factors such as for example vibrations, etc. That is why, 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 occur are the following:
• Efficiency < 0,55 (find table of technical features).
Maintenance
This type of gear reducer will get a permanent lubrication, so that it will not need any kind 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 which has quality level CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; for that reason its maintenance is not needed.
