Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be little, but it’s hard enough to handle demanding power transfer applications. Designed with machined aluminum housings and hardened steel input and result gears, they’ll deliver many years of reliable performance.
Obtainable in three standard output ratios and with two output shaft diameter options, it’s simple to find the Ever-Power correct miniature gearbox to your requirements. Each RW model worm equipment container assembly provides proportionally high torque ideals (1.4 NM at 3,000 RPM) with very low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque predicated on application. Also speed is increased or decreased compared index G – GEAR BOXES – on blue – smallto the speed reduction ratio. Ever-Power has a full line of gearboxes and swiftness reducers, and the components needed to build them, in a wide selection of standard ratios and shaft choices along with custom designs.
Helical, bevel, and miter equipment boxes offer the options of acceleration reducers or acceleration increasers, and could be powered in either direction. All Ever-Power worm equipment speed reducers and right angle drives are produced for powerful in a large spectrum of applications. Typically worm equipment boxes aren’t used as velocity increasers. The situations are molded glass-filled materials making them extremely rugged and resistant to corrosive environments. They can be found in an array of ratios and are built with right hands or left hand worm gears. The output shafts may be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear speed reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and are found in mechanical applications ranging from conveyors to physical exercise 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 into a slot of the driven 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 unique gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth running of the worm equipment combined with the use of cast iron and high precision on element manufacturing and assembly. In connection with our precision gearboxes, we take extra care of any sound that can be interpreted as a murmur from the gear. Therefore 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 frequently proves to be a decisive advantage making the incorporation of the gearbox considerably simpler and smaller sized.The worm gearbox is an angle gear. This is an edge for incorporation into constructions.
Solid bearings in solid housing
The output shaft of the BJ worm gearbox is very firmly embedded in the apparatus house and is perfect 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 will provide a self-locking impact, which in many circumstances can be used as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited 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 kinds of gear-reducer. This make them perform efficiently under stressed conditions, vibrations or any type of setback that cannot be avoided during the assembly
The worm-gear is constructed 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. Because of the mechanical work of the two parts having top quality, excellent functionality 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, 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 in the marketplace.
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 offers like reference size 63 and exists like answer to the demand of our costumers since, upon mounting higher bearings in the output, bears higher axial loads that its analogous one in the MF-62 series. The rest of technical characteristic are identical 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 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 essential 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 focus on this aspect when the gear reducer output shaft is driven instead of being a driver. Considering that one of the top features of this worm-gear reducer is the fact that cannot be axle-driven by the output shaft (irreversibility), it is almost extremely hard to meet total irreversibility conditions, due to external factors such as for example vibrations, etc. For this reason, when the application requires total irreversibility, it really is advisable to make use of exterior brakes with enough power to avoid slipping.
It could be said that the circumstances under which irreversibility can occur are the following:
• Efficiency < 0,55 (see table of technical features).
Maintenance
This kind of gear reducer will get a permanent lubrication, so it will not need any type of maintenance.
Lubrication
The lubrication of this gear reducer type is constant and comes as standard, with top 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; because of this its maintenance isn’t needed.
