Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be small, but it’s hard enough to handle demanding power transfer applications. Constructed with machined aluminum housings and hardened metal input and output gears, they’ll deliver a long time of reliable performance.
Available in three standard result ratios and with two result shaft diameter options, it’s simple 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 may increase or reduce that torque based on application. Also velocity is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed reduction ratio. Ever-Power includes a full line of gearboxes and velocity reducers, and the parts needed to build them, in an array of standard ratios and shaft choices and also custom designs.
Helical, bevel, and miter equipment boxes provide options of rate reducers or velocity increasers, and could be driven in either direction. All Ever-Power worm equipment speed reducers and correct angle drives are manufactured for high performance in a large spectrum of applications. Typically worm gear boxes aren’t used as quickness increasers. The cases are molded glass-filled materials making them extremely rugged and resistant to corrosive conditions. They are offered in an array of ratios and are built with right hand or left hand worm gears. The output shafts could be solid or hollow, and load capability is unaffected by path and rotation.
Worm gear swiftness reducers are made up of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and so are used in mechanical applications ranging from conveyors to workout devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary movement 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 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 really quiet. This is due to the very smooth running of the worm gear combined with the usage of cast iron and high precision on element manufacturing and assembly. In connection with our precision gearboxes, we consider extra treatment of any sound which can be interpreted as a murmur from the apparatus. So the general noise degree of our gearbox is 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 substantially simpler and smaller sized.The worm gearbox is 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 apparatus house and is ideal for direct suspension for wheels, movable arms and other areas rather than having to create 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 utilized as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited 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 are available for all sorts 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 these two parts having high quality, excellent efficiency and low noise levels have been achived.
The output shaft is hollow, although it is possible to adapt a good shaft.
The oil seals manufactured from 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), supply the most competitive gear reducer available.
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 ask for of our costumers since, upon mounting higher bearings in the result, bears better axial loads that its analogous one in the MF-62 series. The rest of technical feature are identical to the its analogous in the size 62.
Assembly Position
In order to setup a gear reducer and to make it work 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 recommended to insert compensating couplings, connectors, torque limiters etc…
If the gear reducer needed to be painted, the oil seals should be covered to avoid them from drying and losing their seal.
The machine work of the fittings setup in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this aspect when the apparatus reducer result shaft is driven instead of being a driver. Considering that one of the top features of this worm-gear reducer is the fact that can’t be axle-driven by the result shaft (irreversibility), it is almost difficult to meet up total irreversibility conditions, because of external factors such as for example vibrations, etc. This is why, when the application needs total irreversibility, it really is advisable to make use of external 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 is provided with a permanent lubrication, so it really does not need any type of maintenance.
Lubrication
The lubrication of this gear reducer type is continuous and comes as standard, with top quality refined oil which includes 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.
