Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be small, but it’s difficult enough to handle demanding power transfer applications. Designed with machined light weight aluminum housings and hardened steel input and output gears, they’ll deliver many years of reliable performance.
Available in three standard result ratios and with two result shaft diameter options, it’s easy to find the Ever-Power right miniature gearbox for your needs. Each RW model worm gear 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 decreased compared index G – GEAR BOXES – on blue – smallto the speed reduction ratio. Ever-Power includes a full line of gearboxes and rate reducers, and the components needed to build them, in a wide selection of regular ratios and shaft options along with custom designs.
Helical, bevel, and miter equipment boxes offer the options of swiftness reducers or velocity increasers, and could be driven in either direction. All Ever-Power worm gear speed reducers and right angle drives are produced for high performance in a large spectrum of applications. Typically worm equipment boxes are not used as acceleration increasers. The instances are molded glass-filled materials making them extremely tough and resistant to corrosive environments. They are offered in a wide variety 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 single enveloping wheel and so are used in mechanical applications ranging from conveyors to workout 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 reaches right into a slot of the driven wheel advancing it by one stage and a blocking disc that locks the driven 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 can be achieved through the use of adapted gearboxes or unique gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth operating of the worm gear combined with the usage of cast iron and high precision on element manufacturing and assembly. Regarding the our precision gearboxes, we take extra care of any sound that can be interpreted as a murmur from the apparatus. So the general noise degree of our gearbox is 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 be a decisive advantage making the incorporation of the gearbox substantially simpler and more compact.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 gear house and is well suited 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 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 constructed with GG-25 cast-iron, and are available for all sorts of gear-reducer. This make sure they are perform efficiently under stressed circumstances, 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 made of DIN (GZ-CuSn 12 Ni2) centricast bronze, melted on steel. Due to the mechanical work of these two parts having high quality, excellent overall performance and low sound amounts have been achived.
The output shaft is hollow, though it can be done 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), supply 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 response to the demand of our costumers since, upon mounting greater bearings in the output, bears better 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 set up a gear reducer and to make it happen efficiently, the following instructions must be considered:
It must 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 needed to be painted, the essential oil seals should be covered to prevent them from drying and losing their seal.
The device work of the fittings set up in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart 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 top features of this worm-gear reducer is the fact that can’t be axle-driven by the output shaft (irreversibility), it is almost impossible to meet up total irreversibility conditions, because of external elements such as for example vibrations, etc. This is why, when the application needs total irreversibility, it really is advisable to make use of exterior brakes with enough capacity to avoid slipping.
It may be said that the circumstances under which irreversibility can happen are the following:
• Efficiency < 0,55 (observe table of specialized features).
Maintenance
This type of gear reducer is provided with a permanent lubrication, so that it really does not need any kind of maintenance.
Lubrication
The lubrication of the gear reducer type is continuous and comes as standard, with high quality refined oil which has 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.
