Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be small, but it’s hard enough to handle demanding ability transfer applications. Constructed with machined aluminium housings and hardened steel input and output gears, they’ll deliver many years of reliable performance.
Obtainable in three standard output 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 box assembly provides proportionally substantial torque ideals (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 velocity is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed reduction ratio. EP has a full type of gearboxes and velocity reducers, and the components needed to build them, in an array of standard ratios and shaft options along with custom designs.
Helical, bevel, and miter gear boxes provide options of swiftness reducers or rate increasers, and may be powered in either direction. All EP worm gear speed reducers and correct angle drives are produced for high performance in a large spectrum of applications. Typically worm gear boxes are not used as acceleration increasers. The situations are molded glass-filled material making them extremely durable and resilient to corrosive conditions. They are offered in an array of ratios and are built with right hand or left hand worm gears. The output shafts may be sound 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 are used in mechanical applications which range from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary movement into intermittent rotary motion. The rotating drive steering wheel has a pin that gets to right into a slot of the driven wheel advancing it by one step and a blocking disk that locks the powered wheel constantly in place between steps.
Kontra enfòmèl ant konsepsyon
Compact design is among the key phrases of the standard gearboxes of the BJ-Series. Further optimisation can be achieved by using adapted gearboxes or particular gearboxes.
Ba bri
Our worm gearboxes and actuators are really quiet. This is due to the very smooth operating of the worm equipment combined with the use of cast iron and excessive precision on element manufacturing and assembly. Regarding the our precision gearboxes, we consider extra treatment of any sound which can be interpreted as a murmur from the apparatus. Therefore the general noise degree 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 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 very firmly embedded in the gear 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 equipment ratios,EP-Gear’s worm gearboxes will provide a self-locking impact, which in many situations can be used as brake or as extra security. Likewise spindle gearboxes with a trapezoidal spindle will be self-locking, making them well suited for an array of solutions.
Karakteristik estriktirèl
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 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 top quality, excellent performance and low noises 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), supply the best 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 has like reference size 63 and exists like answer to the request of our costumers since, after mounting better bearings in the output, bears better axial loads that its analogous one in the MF-62 series. The others of technical characteristic are identical to the its analogous in the size 62.
Pozisyon Asanble
In order to create a gear reducer and to make it happen efficiently, the following instructions must be taken into account:
It must be fixed on a flat 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 apparatus reducer needed to be painted, the oil seals should be covered to avoid them from drying and losing their seal.
The device work of the fittings set up in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to pay attention to this aspect 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 can’t be axle-powered by the output shaft (irreversibility), it is almost impossible to meet total irreversibility conditions, because of external elements such as vibrations, etc. This is why, when the application requires total irreversibility, it is advisable to make use of external brakes with enough capacity to avoid slipping.
It may be said that the conditions under which irreversibility can occur are the following:
• Efficiency < 0,55 (find table of technical features).
antretyen
This kind of gear reducer is provided with a permanent lubrication, so it will not need any type of maintenance.
Wilaj
The lubrication of the gear reducer type is constant and comes as standard, with high quality refined oil which has antirust and antiwear products with Fe, Cu and alloy protectors which has level of quality CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; for that reason its maintenance is not needed.
