Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be tiny, but it’s difficult enough to take care of demanding electric power transfer applications. Constructed with machined aluminium housings and hardened steel input and result gears, they’ll deliver many years of reliable performance.
Obtainable in three standard result ratios and with several output shaft diameter options, it’s simple to find the EP correct miniature gearbox for your needs. Each RW style worm gear container assembly provides proportionally substantial torque values (1.4 NM at 3,000 RPM) with very low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque based on application. Also velocity is increased or reduced compared index G – GEAR BOXES – on blue – smallto the speed reduction ratio. EP includes a full line of gearboxes and quickness reducers, and the components needed to build them, in a wide variety of regular ratios and shaft choices as well as custom designs.
Helical, bevel, and miter gear boxes offer the options of swiftness reducers or speed increasers, and may be powered in either direction. All EP worm gear speed reducers and correct angle drives are produced for powerful in a large spectral range of applications. Commonly worm gear boxes aren’t used as rate increasers. The instances are molded glass-filled material making them extremely rugged and resistant to corrosive environments. They can be found in a wide selection of ratios and are built with right hands or left hand worm gears. The output shafts may be solid or hollow, and load capability is unaffected by path and rotation.
Worm gear acceleration reducers are comprised of a good screw (the worm) that drives a steering wheel (helical gear) or one enveloping wheel and 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 motion. The rotating drive wheel includes a pin that reaches right into a slot of the driven steering wheel advancing it by one step and a blocking disk that locks the powered wheel constantly in place between steps.
Compact design is among the key phrases of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or special gearboxes.
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth operating of the worm equipment combined with the usage of cast iron and high precision on component manufacturing and assembly. Regarding the our accuracy gearboxes, we take extra care of any sound which can be interpreted as a murmur from the gear. So the general noise level of our gearbox is usually reduced to a complete minimum.
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This often proves to become a decisive advantage making the incorporation of the gearbox substantially simpler and smaller sized.The worm gearbox can be 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 ideal for immediate suspension for wheels, movable arms and other parts rather than needing to create a separate suspension.
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 protection. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited for an array of solutions.
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 sorts of gear-reducer. This make sure they are perform efficiently under stressed conditions, vibrations or any kind of setback that cannot be avoided through the assembly
The worm-gear is made of 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. Due to the mechanical work of the two parts having high quality, excellent functionality and low sound levels have been achived.
The output shaft is hollow, although it is possible to adapt a solid 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), provide the most competitive gear reducer in the marketplace.
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 response to the ask for of our costumers since, upon mounting greater bearings in the output, bears higher axial loads that its analogous one in the MF-62 series. The others of technical feature are identical to the its analogous in the size 62.
In order to set up a gear reducer and to make it work efficiently, the following instructions must be considered:
It should be fixed on a flat surface to avoid either vibrations or perhaps tensions.
If undistributed loads or continued start-ups are foreseen, it is suggested to insert compensating couplings, connectors, torque limiters etc…
If the gear reducer had to be painted, the oil seals should be covered to prevent 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.
It is wise to focus on this aspect when the gear reducer output shaft is driven instead of being a driver. Bearing in mind that one of the features of this worm-equipment reducer may be the fact that cannot be axle-powered by the result shaft (irreversibility), it is almost unattainable to meet total irreversibility conditions, because of external factors such as vibrations, etc. This is why, when the application requires total irreversibility, it really is advisable to make use of external brakes with enough capacity to avoid slipping.
It could be said that the circumstances under which irreversibility can occur are the following:
• Efficiency < 0,55 (find table of technical features).
This kind of gear reducer will get a permanent lubrication, so that it will not need any kind of maintenance.
The lubrication of the 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 which has quality level CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; for that reason its maintenance isn’t needed.
