Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be little, but it’s challenging enough to take care of demanding power transfer applications. Designed with machined light weight aluminum housings and hardened metal input and output gears, they’ll deliver a long time of reliable performance.
Available in three standard output ratios and with two output shaft diameter options, it’s simple to find the Ever-Power correct miniature gearbox to your requirements. Each RW model worm equipment box assembly provides proportionally high torque values (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 based on application. Also quickness is increased or decreased in proportion index G – Equipment BOXES – on blue – smallto the speed reduction ratio. Ever-Power includes a full type of gearboxes and acceleration reducers, and the components had a need to build them, in an array of regular ratios and shaft options in addition to custom designs.
Helical, bevel, and miter gear boxes provide options of velocity reducers or speed increasers, and may be driven in either path. All Ever-Power worm equipment speed reducers and right angle drives are manufactured for high performance in a large spectral range of applications. Typically worm equipment boxes are not used as velocity increasers. The situations are molded glass-filled material making them extremely durable and resistant to corrosive conditions. They are offered in an array of ratios and are equipped with right hand or left hand worm gears. The output shafts could be solid or hollow, and load capability is unaffected by path and rotation.
Worm gear rate reducers are made up of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and are used in mechanical applications ranging from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary movement into intermittent rotary movement. The rotating drive wheel has a pin that gets to right into a slot of the driven wheel advancing it by one stage and a blocking disc that locks the driven 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 through the use of adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth running of the worm gear combined with the use of cast iron and high precision on element manufacturing and assembly. Regarding the our precision gearboxes, we take extra treatment of any sound that can be interpreted as a murmur from the gear. So the general noise level of our gearbox is definitely reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This often proves to be a decisive advantage producing the incorporation of the gearbox significantly simpler and more compact.The worm gearbox is an angle gear. This is often 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 direct 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 situations can be used as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited for an array of solutions.
Structural Features
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 are available for all sorts of gear-reducer. This make them perform efficiently under stressed conditions, vibrations or any kind 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 manufactured from DIN (GZ-CuSn 12 Ni2) centricast bronze, melted on steel. Due to the mechanical work of these two parts having high quality, excellent overall performance and low noise levels have been achived.
The output shaft is hollow, though it is possible 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 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 offers like reference size 63 and exists like answer to the demand of our costumers since, upon mounting greater bearings in the output, bears greater 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 setup a gear reducer and also to make it work efficiently, the next instructions must be considered:
It should be fixed on a set surface to avoid either vibrations or 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 needed to be painted, the essential oil seals must be covered to avoid them from drying and losing their seal.
The device work of the fittings create in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this factor when the apparatus reducer result shaft is driven instead of being a driver. Bearing in mind 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 total irreversibility conditions, due to external factors such as 
for example vibrations, etc. For this reason, when the application form needs total irreversibility, it really is advisable to make use of exterior brakes with enough capacity to avoid slipping.
It could be said that the circumstances under which irreversibility can occur are the following:
• Efficiency < 0,55 (discover table of technical features).
Maintenance
This kind of gear reducer will get a permanent lubrication, so that it does 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 has 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 is not needed.
