Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be small, but it’s challenging enough to handle demanding electricity transfer applications. Designed with machined aluminum housings and hardened steel input and output gears, they’ll deliver a long time of reliable performance.
Available in three standard result ratios and with several output shaft diameter options, it’s easy to find the EP correct miniature gearbox for your needs. Each RW style worm gear box assembly provides proportionally excessive torque ideals (1.4 NM at 3,000 RPM) with very low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque predicated on application. Also velocity is increased or decreased in proportion index G – Equipment BOXES – on blue – smallto the speed reduction ratio. EP includes a full type of gearboxes and acceleration reducers, and the components needed to build them, in a wide selection of regular ratios and shaft choices as well as custom designs.
Helical, bevel, and miter gear boxes offer the options of speed reducers or velocity increasers, and could be driven in either direction. All EP worm equipment speed reducers and right angle drives are manufactured for high performance in a large spectrum of applications. Typically worm gear boxes are not used as acceleration increasers. The cases are molded glass-filled materials making them extremely durable and resistant to corrosive environments. They are offered in a wide range of ratios and are equipped with right hand or left hands worm gears. The output shafts may be solid or hollow, and load capability is unaffected by path and rotation.
Worm gear rate reducers are made up of a good screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and are found in mechanical applications ranging from conveyors to workout devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary motion into intermittent rotary motion. The rotating drive wheel has a pin that gets to into a slot of the powered steering wheel advancing it by one stage and a blocking disk that locks the driven wheel in position between steps.
Compact design
Compact design is among the key phrases of the typical gearboxes of the BJ-Series. Further optimisation can be achieved by using adapted gearboxes or unique gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is because of the very smooth operating of the worm gear combined with the usage of cast iron and huge precision on element manufacturing and assembly. In connection with our precision gearboxes, we take extra treatment of any sound that can be interpreted as a murmur from the gear. So the general noise degree of our gearbox is usually reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This generally 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 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 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 will provide a self-locking impact, 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 ideal for an array of solutions.
Structural Features
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are made from GG-25 cast-iron, and so are available for all sorts of gear-reducer. This make sure they are perform effectively under stressed conditions, vibrations or any type 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 made of DIN (GZ-CuSn 12 Ni2) centricast bronze, melted on steel. Due to the mechanical work of the two parts having high quality, excellent performance and low noise levels have been achived.
The output shaft is hollow, although 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), provide 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 response to the demand of our costumers since, after mounting higher bearings in the output, bears higher axial loads that its analogous one in the MF-62 series. The rest of technical characteristic are identical to the its analogous in the size 62.
Assembly Position
In order to create a gear reducer and also to make it happen efficiently, the next 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 gear reducer needed to be painted, the essential oil seals should be covered to prevent 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 wise to focus on this element when the gear reducer result shaft is driven instead of being a driver. Considering that among the top features of this worm-gear reducer may be the fact that can’t be axle-powered by the output shaft (irreversibility), it really is almost difficult to meet up total irreversibility conditions, due to external factors such as vibrations, etc. This is why, when the application needs total irreversibility, it really is advisable to make use of external brakes with enough power to avoid slipping.
It may be said that the circumstances under which irreversibility can happen are as follows:
• Efficiency < 0,55 (find table of technical features).
Maintenance
This type of gear reducer will get a permanent lubrication, so it will not need any kind of maintenance.
Lubrication
The lubrication of this gear reducer type is constant and comes as standard, with high 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.
