Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be small, but it’s hard enough to take care of demanding ability transfer applications. Constructed with machined light weight aluminum housings and hardened steel input and output gears, they’ll deliver a long time of reliable performance.
Obtainable in three standard result ratios and with several output shaft size options, it’s easy to find the EP correct miniature gearbox to your requirements. Each RW version worm gear box 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 could increase or reduce that torque based on application. Also rate is increased or reduced in proportion index G – GEAR BOXES – on blue – smallto the speed decrease ratio. EP has a full line of gearboxes and velocity reducers, and the components needed to build them, in a wide range of regular ratios and shaft choices as well as custom designs.
Helical, bevel, and miter equipment boxes provide options of quickness reducers or speed increasers, and may be driven in either direction. All EP worm equipment speed reducers and correct angle drives are produced for high performance in a large spectrum of applications. Typically worm gear boxes aren’t used as speed increasers. The cases are molded glass-filled material making them extremely durable and resistant to corrosive environments. They can be found in a wide selection of ratios and are equipped with right hand or left hands worm gears. The output shafts may be sound or hollow, and load capacity is unaffected by path and rotation.
Worm gear speed reducers are made up of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and are used 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 steering 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 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 unique gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth running of the worm gear combined with the use of cast iron and large 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 gear. 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 generally proves to be a decisive advantage producing the incorporation of the gearbox substantially simpler and more compact.The worm gearbox is an angle gear. This is an advantage for incorporation into constructions.
Strong bearings in solid housing
The output shaft of the BJ worm gearbox is very firmly embedded in the gear house and is perfect for immediate suspension for wheels, movable arms and other parts rather than needing to create a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes will provide a self-locking effect, which in many circumstances can be used as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle will be self-locking, making them perfect for an array of solutions.
Structural Features
The worm-gear reducer comprises 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 efficiently under stressed conditions, vibrations or any type of setback that can’t be avoided during the assembly
The worm-gear is made from 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 top quality, excellent functionality and low noise levels have been achived.
The output shaft is hollow, although it can be done 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 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 exists like answer to the request of our costumers since, after mounting higher bearings in the result, 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.
Assembly Position
In order to create a gear reducer and also to make it work efficiently, the next instructions must be considered:
It should 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 suggested to insert compensating couplings, connectors, torque limiters etc…
If the gear 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 set up in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this point when the apparatus reducer result shaft is driven rather than being a driver. Considering that among the features of this worm-equipment reducer is the fact that cannot be axle-driven by the output shaft (irreversibility), it is almost unattainable to meet total irreversibility conditions, due to external factors such as for example vibrations, etc. For this reason, when the application requires total irreversibility, it is advisable to utilize external brakes with enough power to avoid slipping.
It could be said that the conditions under which irreversibility can occur are the following:
• Efficiency < 0,55 (find table of specialized features).
Maintenance
This sort of gear reducer will get a permanent lubrication, so that 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 includes 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.
