Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be tiny, but it’s difficult enough to take care of demanding vitality transfer applications. Designed with machined light weight aluminum housings and hardened metal 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 easy to find the EP correct miniature gearbox to your requirements. Each RW unit worm gear package assembly provides proportionally substantial torque ideals (1.4 NM at 3,000 RPM) with suprisingly low backlash (maximum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque predicated on application. Also rate is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed reduction ratio. EP has a full line of gearboxes and quickness reducers, and the components had a need to build them, in a wide selection of regular ratios and shaft options as well as custom designs.
Helical, bevel, and miter gear boxes offer the options of acceleration reducers or quickness increasers, and could be driven in either direction. All EP worm gear speed reducers and correct angle drives are manufactured for high performance in a large spectrum of applications. Commonly worm gear boxes are not used as velocity increasers. The cases are molded glass-filled materials making them extremely rugged and resilient to corrosive conditions. They are offered in an array of ratios and are equipped with right hands or left hand worm gears. The result shafts may be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear rate reducers are comprised of a good screw (the worm) that drives a wheel (helical gear) or one 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 movement into intermittent rotary movement. The rotating drive steering wheel has a pin that reaches right into a slot of the powered wheel advancing it by one stage and a blocking disk that locks the powered wheel constantly in place between steps.
Compact design
Compact design is one of the key terms of the typical gearboxes of the BJ-Series. Further optimisation may be accomplished through the use of adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth working of the worm gear combined with the usage of cast iron and substantial precision on element manufacturing and assembly. Regarding the our precision gearboxes, we consider extra care of any sound that can be interpreted as a murmur from the apparatus. So the general noise level of our gearbox is certainly reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This quite often proves to become a decisive advantage making the incorporation of the gearbox substantially simpler and more compact.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 quite firmly embedded in the apparatus house and is perfect for direct suspension for wheels, movable arms and other parts rather than needing to build 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. As well spindle gearboxes with a trapezoidal spindle happen to be self-locking, making them well suited for an array 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 so are available for all types of gear-reducer. This make them perform effectively under stressed conditions, vibrations or any type of setback that cannot be avoided through 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. Due to the mechanical work of these two parts having top quality, excellent efficiency and low sound amounts have been achived.
The output shaft is hollow, though 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), provide 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 demand of our costumers since, after mounting greater bearings in the output, bears better axial loads that its analogous one in the MF-62 series. The others of technical feature are similar to the its analogous in the size 62.
Assembly Position
In order to setup a gear reducer and also to make it work efficiently, the next 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 had to be painted, the essential oil seals must be covered to avoid 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 issue when the gear reducer result 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-driven by the output shaft (irreversibility), it really is almost difficult to meet total irreversibility conditions, due to external elements such as vibrations, etc. For this reason, 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 occur are the following:
• Efficiency < 0,55 (discover table of technical features).
Maintenance
This sort of gear reducer will get a permanent lubrication, so that it will not need any type of maintenance.
Lubrication
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 that has level of quality CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; because of this its maintenance is not needed.
