Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be tiny, but it’s tough enough to handle demanding electric power transfer applications. Designed with machined aluminium housings and hardened metal input and output gears, they’ll deliver a long time 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 to your requirements. Each RW version worm gear package assembly provides proportionally large torque ideals (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 based on application. Also acceleration 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 elements needed to build them, in a wide selection of regular ratios and shaft choices and also custom designs.
Helical, bevel, and miter equipment boxes provide options of rate reducers or acceleration increasers, and could be powered in either path. All EP worm gear speed reducers and right angle drives are produced for powerful in a large spectrum of applications. Commonly worm gear boxes are not used as swiftness increasers. The cases are molded glass-filled materials making them extremely tough and tolerant to corrosive environments. They are offered in an array of ratios and are built with right hand or left hands worm gears. The result shafts may be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear acceleration reducers are made up of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and so are used in mechanical applications which range 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 wheel has a pin that gets to right into a slot of the powered steering wheel advancing it by one stage and a blocking disk that locks the driven wheel constantly in place between steps.
Compact design
Compact design is one of the key terms of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished through the use of 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 use of cast iron and huge precision on element manufacturing and assembly. In connection with our accuracy gearboxes, we consider extra treatment of any sound that can be interpreted as a murmur from the apparatus. Therefore the general noise degree of our gearbox is usually reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This typically proves to become a decisive advantage making the incorporation of the gearbox significantly simpler and more compact.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 well suited for direct suspension for wheels, movable arms and other areas rather than having to build a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes provides a self-locking impact, which in many circumstances can be used as brake or as extra security. Likewise spindle gearboxes with a trapezoidal spindle happen to be self-locking, making them perfect 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 constructed with GG-25 cast-iron, and are available for all sorts of gear-reducer. This make them perform efficiently under stressed circumstances, vibrations or any kind of setback that cannot be avoided during 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. Because of the mechanical work of the two parts having high quality, excellent efficiency and low noises amounts have been achived.
The output shaft is hollow, although it is possible to adapt a good shaft.
The oil seals made of 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 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 provides like reference size 63 and is born like response to the request of our costumers since, upon mounting higher bearings in the result, bears greater 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 setup a gear reducer and also to make it work efficiently, the next instructions must be taken into account:
It should be fixed on a set surface 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 apparatus 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 need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this element when the apparatus reducer output shaft is driven rather than being a driver. Bearing in mind that among the top features of this worm-equipment reducer is the fact that can’t be axle-powered by the result shaft (irreversibility), it really is almost impossible to meet total irreversibility conditions, due to external factors such as vibrations, etc. That is why, 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 happen are as follows:
• Efficiency < 0,55 (find table of technical features).
Maintenance
This sort of gear reducer will get a permanent lubrication, so it does not need any type of maintenance.
Lubrication
The lubrication of this gear reducer type is constant and comes as standard, with top quality refined oil which includes 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.
