Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be little, but it’s difficult enough to take care of demanding power transfer applications. Designed with machined aluminum 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 output shaft diameter options, it’s easy to find the Ever-Power right miniature gearbox to your requirements. Each RW model worm equipment container 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 predicated on application. Also rate is increased or reduced compared index G – GEAR BOXES – on blue – smallto the speed decrease ratio. Ever-Power has a full type of gearboxes and acceleration reducers, and the parts had a need to build them, in a wide range of standard ratios and shaft options in addition to custom designs.
Helical, bevel, and miter gear boxes offer the options of acceleration reducers or acceleration increasers, and could be powered in either path. All Ever-Power worm gear speed reducers and right angle drives are produced for high performance in a large spectral range of applications. Typically worm equipment boxes are not used as acceleration increasers. The situations are molded glass-filled materials making them extremely durable and resistant to corrosive conditions. They are offered in a wide range of ratios and are built with right hands or left hand worm gears. The result shafts may be solid or hollow, and load capability is unaffected by direction and rotation.
Worm gear rate reducers are made up of a screw (the worm) that drives a wheel (helical gear) or solitary 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 movement. The rotating drive wheel has 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 one of the key terms of the standard gearboxes of the BJ-Series. Further optimisation can be achieved by using adapted gearboxes or particular gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is due to the very smooth operating 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 consider extra treatment of any sound that can be interpreted as a murmur from the apparatus. Therefore the general noise level of our gearbox is definitely reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This frequently proves to become a decisive advantage producing the incorporation of the gearbox considerably simpler and smaller sized.The worm gearbox is an angle gear. This is often an edge for incorporation into constructions.
Solid bearings in solid housing
The output shaft of the BJ worm gearbox is quite firmly embedded in the apparatus house and is perfect for immediate suspension for wheels, movable arms and other parts rather than needing to create a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes will provide a self-locking effect, 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 perfect for a wide selection of solutions.
Structural Features
The worm-gear reducer is made up of three main parts: housing, worm-gear and wheel.
The carcasses are constructed with GG-25 cast-iron, and so are available for all sorts of gear-reducer. This make sure they are perform effectively under stressed circumstances, vibrations or any type of setback that cannot 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 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 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 demand 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 others of technical feature are similar to the its analogous in the size 62.
Assembly Position
In order to setup a gear reducer and also to make it happen efficiently, the next instructions must be considered:
It must be fixed on a set surface 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 had to be painted, the oil seals should be covered to prevent them from drying and losing their seal.
The machine work of the fittings create in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this factor when the apparatus reducer result shaft is driven instead of being a driver. Bearing in mind that among the features of this worm-equipment reducer may be the fact that can’t be axle-powered by the output shaft (irreversibility), it is almost impossible to meet up total irreversibility conditions, due to external factors such as for example vibrations, etc. This is why, when the application form needs total irreversibility, it really is advisable to utilize exterior brakes with enough power to avoid slipping.
It may be said that the circumstances under which irreversibility can occur are the following:
• Efficiency < 0,55 (find table of technical features).
Maintenance
This sort of gear reducer is provided with 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 high 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 isn’t needed.
