Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be small, but it's tough enough to take care of demanding power transfer applications. Constructed with machined aluminium housings and hardened steel input and result gears, they'll deliver a long time 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 for your needs. Each RW model worm gear package assembly provides proportionally high torque ideals (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 swiftness is increased or reduced compared index G – Equipment BOXES – on blue – smallto the speed reduction ratio. Ever-Power includes a full line of gearboxes and rate reducers, and the components had a need to build them, in a wide selection of regular ratios and shaft choices as well as custom designs.
Helical, bevel, and miter gear boxes offer the options of quickness reducers or acceleration increasers, and could be driven in either path. All Ever-Power worm equipment speed reducers and correct angle drives are manufactured for powerful in a large spectral range of applications. Typically worm equipment boxes are not used as swiftness increasers. The cases are molded glass-filled material making them extremely tough and resistant to corrosive environments. They can be found in a wide variety of ratios and are built with right hand or left hands worm gears. The result shafts could be solid or hollow, and load capability is unaffected by path and rotation.
Worm gear rate 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 ranging from conveyors to workout devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary motion into intermittent rotary motion. 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 powered wheel in position between steps.
Compact design
Compact design is one of the key terms 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. Regarding the 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 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 become a decisive advantage making the incorporation of the gearbox significantly simpler and smaller sized.The worm gearbox is 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 quite firmly embedded in the apparatus house and is ideal for direct 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 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 comprises of three main parts: housing, worm-gear and wheel.
The carcasses are made from GG-25 cast-iron, and are available for all kinds of gear-reducer. This make them perform efficiently under stressed circumstances, vibrations or any type of setback that cannot be avoided during 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 efficiency and low noise levels have been achived.
The output shaft is hollow, though it can be done to adapt a good 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 on the market.
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 better bearings in the result, bears greater axial loads that its analogous one in the MF-62 series. The rest of technical characteristic are similar 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 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 had to be painted, the oil seals must be covered to avoid them from drying and losing their seal.
The device work of the fittings setup 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 gear reducer result shaft is driven instead of 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 really is almost extremely hard to meet up total irreversibility conditions, because of external factors such as vibrations, etc. For this reason, when the application form needs total irreversibility, it is advisable to utilize exterior brakes with enough capacity to avoid slipping.
It could be said that the circumstances under which irreversibility can occur are as follows:
• Efficiency Maintenance
This type of gear reducer is provided with a permanent lubrication, so it will not need any kind of maintenance.
Lubrication
The lubrication of this 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; for that reason its maintenance is not needed.
