Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be little, but it’s difficult enough to take care of demanding vitality transfer applications. Designed with machined aluminium housings and hardened steel input and output gears, they’ll deliver a long time of reliable performance.
Available in three standard output ratios and with several output shaft diameter options, it’s simple to find the EP right miniature gearbox to your requirements. Each RW version worm gear package assembly provides proportionally excessive torque values (1.4 NM at 3,000 RPM) with suprisingly low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque based on application. Also swiftness is increased or decreased compared index G – GEAR BOXES – on blue – smallto the speed decrease ratio. EP has a full line of gearboxes and acceleration reducers, and the parts had a need to build them, in a wide selection of regular ratios and shaft choices in addition to custom designs.
Helical, bevel, and miter equipment boxes provide options of acceleration reducers or velocity increasers, and could be driven in either path. All EP worm equipment speed reducers and correct angle drives are produced for high performance in a large spectral range of applications. Typically worm gear boxes are not used as quickness increasers. The situations are molded glass-filled material making them extremely tough and resilient to corrosive environments. They are offered in a wide selection of ratios and are built with right hands or left hand worm gears. The result shafts may be sturdy or hollow, and load capability is unaffected by path and rotation.
Worm gear acceleration reducers are made up of a good screw (the worm) that drives a steering wheel (helical gear) or single enveloping wheel and so are found in mechanical applications which range from conveyors to exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary motion into intermittent rotary movement. The rotating drive wheel includes a pin that reaches right into a slot of the powered wheel advancing it by one step and a blocking disc that locks the powered wheel constantly in place between steps.
Compact design
Compact design is among the key words of the typical gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or particular gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is due to the very smooth working of the worm gear combined with the usage of cast iron and high precision on component manufacturing and assembly. Regarding the our accuracy gearboxes, we consider extra treatment of any sound which can be interpreted as a murmur from the apparatus. So the general noise level of our gearbox is usually reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This quite often proves to become a decisive advantage making the incorporation of the gearbox considerably simpler and more compact.The worm gearbox is an angle gear. This is often an advantage for incorporation into constructions.
Strong bearings in solid housing
The output shaft of the BJ worm gearbox is quite firmly embedded in the apparatus house and is ideal for immediate suspension for wheels, movable arms and other areas rather than having to create a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes will provide a self-locking impact, which in many situations can be utilized as brake or as extra protection. Likewise spindle gearboxes with a trapezoidal spindle happen to be self-locking, making them ideal 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 made from GG-25 cast-iron, and so are available for all kinds of gear-reducer. This make sure they are perform effectively 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 these two parts having high quality, excellent efficiency and low sound levels have been achived.
The output shaft is hollow, though it can be done to adapt a good shaft.
The oil seals manufactured from 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 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 is born like answer to the request of our costumers since, after mounting greater bearings in the output, bears higher 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 create a gear reducer and to make it happen efficiently, the next instructions must be taken into account:
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 essential oil seals must be covered to prevent them from drying and losing their seal.
The device work of the fittings create in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this aspect when the apparatus reducer output shaft is driven rather than being a driver. Bearing in mind that among the features of this worm-equipment reducer is the fact that can’t be axle-powered by the result shaft (irreversibility), it really is almost unattainable to meet total irreversibility conditions, due to external elements such as for example vibrations, etc. That is why, when the application needs total irreversibility, it 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 as follows:
• Efficiency < 0,55 (see table of specialized features).
Maintenance
This type of gear reducer will get a permanent lubrication, so that it will not need any kind of maintenance.
Lubrication
The lubrication of this gear reducer type is continuous and comes as standard, with top quality refined oil which has antirust and antiwear products with Fe, Cu and alloy protectors that 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.
