Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be tiny, but it’s challenging enough to handle demanding electricity transfer applications. Designed with machined aluminium housings and hardened metal input and output gears, they’ll deliver many years of reliable performance.
Available in three standard result ratios and with two output shaft diameter options, it’s easy to find the EP correct miniature gearbox to your requirements. Each RW unit worm gear container assembly provides proportionally large torque values (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 predicated on application. Also speed is increased or decreased compared index G – GEAR BOXES – on blue – smallto the speed decrease ratio. EP has a full line of gearboxes and quickness reducers, and the parts had a need to build them, in a wide variety of regular ratios and shaft choices as well as custom designs.
Helical, bevel, and miter equipment boxes offer the options of quickness reducers or quickness increasers, and may be driven in either path. 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 aren’t used as acceleration increasers. The cases are molded glass-filled material making them extremely rugged and resistant to corrosive conditions. They can be found in a wide selection of ratios and are built with right hands or left hand worm gears. The result shafts may be sound or hollow, and load capacity is unaffected by direction and rotation.
Worm gear rate reducers are made up of a good screw (the worm) that drives a steering wheel (helical gear) or one enveloping wheel and are found in mechanical applications ranging from conveyors to exercise devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary movement into intermittent rotary motion. The rotating drive steering wheel includes a pin that reaches right into a slot of the powered steering wheel advancing it by one step and a blocking disc that locks the powered wheel in position between steps.
Compact design
Compact design is one of the key phrases of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or unique gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth working of the worm equipment combined with the usage of cast iron and great precision on component manufacturing and assembly. Regarding the our precision gearboxes, we take extra care of any sound that can be interpreted as a murmur from the apparatus. Therefore the general noise level 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 quite often proves to be a decisive advantage making the incorporation of the gearbox significantly simpler and more compact.The worm gearbox is an angle gear. This is an advantage for incorporation into constructions.
Solid bearings in solid housing
The output shaft of the BJ worm gearbox is quite firmly embedded in the apparatus house and is well suited for immediate suspension for wheels, movable arms and other areas rather than needing to create a separate suspension.
Self locking
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. As well spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited for a wide variety of solutions.
Structural Features
The worm-gear reducer is made up 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 effectively under stressed conditions, vibrations or any kind of setback that can’t be avoided through the assembly
The worm-gear is constructed 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 these two parts having top quality, excellent performance and low sound levels have been achived.
The output shaft is hollow, though it can be done 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), supply the most competitive gear reducer on the market.
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 ask for of our costumers since, upon mounting better bearings in the output, bears greater axial loads that its analogous one in the MF-62 series. The rest of technical characteristic are similar to the its analogous in the size 62.
Assembly Position
In order to set up a gear reducer and also to make it work efficiently, the next instructions must be taken into account:
It must be fixed on a set surface in order to avoid either vibrations or perhaps 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 had to be painted, the oil seals must be covered to prevent them from drying and losing their seal.
The device work of the fittings set up in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to focus on this factor 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-powered by the output shaft (irreversibility), it is almost difficult to meet up total irreversibility conditions, due to external factors such as vibrations, etc. That is why, when the application requires total irreversibility, it really is advisable to utilize external brakes with enough capacity to avoid slipping.
It could be said that the circumstances under which irreversibility can happen are the following:
• Efficiency < 0,55 (observe table of technical features).
Maintenance
This kind of gear reducer is provided with a permanent lubrication, so it will not need any kind of maintenance.
Lubrication
The lubrication of the 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 level of quality CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; because of this its maintenance isn’t needed.
