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. Constructed with machined aluminium housings and hardened metal input and result gears, they’ll deliver a long time of reliable performance.
Obtainable in three standard output ratios and with two output shaft diameter options, it’s easy to find the Ever-Power correct miniature gearbox to your requirements. Each RW model worm equipment package assembly provides proportionally high torque ideals (1.4 NM at 3,000 RPM) with very low backlash (maximum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque based on application. Also speed is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed decrease ratio. Ever-Power has a full type of gearboxes and quickness reducers, and the parts had a need to build them, in an array of standard ratios and shaft choices as well as custom designs.
Helical, bevel, and miter gear boxes provide options of velocity reducers or swiftness increasers, and may be powered in either path. All Ever-Power worm equipment speed reducers and correct angle drives are manufactured for powerful in a large spectral range 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 conditions. They can be found in an array of ratios and are equipped with right hand or left hands worm gears. The output shafts could be solid or hollow, and load 
capacity is unaffected by path and rotation.
Worm gear speed reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or solitary enveloping wheel and are found in mechanical applications which range from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary movement into intermittent rotary movement. The rotating drive wheel includes a pin that gets to into a slot of the powered 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 among the key phrases of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is because of the very smooth running of the worm equipment combined with the use of cast iron and high precision on component manufacturing and assembly. In connection with our precision gearboxes, we consider extra treatment of any sound which can be interpreted as a murmur from the gear. Therefore the general noise level of our gearbox can be reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This frequently proves to become a decisive advantage producing the incorporation of the gearbox considerably simpler and smaller sized.The worm gearbox can be 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 quite firmly embedded in the apparatus 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 gear ratios,EP-Gear’s worm gearboxes will provide a self-locking effect, which in many circumstances can be utilized as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them ideal for a wide variety 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 types of gear-reducer. This make them perform efficiently under stressed conditions, vibrations or any kind of setback that cannot be avoided during the assembly
The worm-gear is constructed 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 functionality and low noise levels have been achived.
The output shaft is hollow, although 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), 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 is born like answer to the ask for 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 create 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 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 oil seals must be covered to avoid them from drying and losing their seal.
The machine 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 factor when the gear reducer result shaft is driven instead of being a driver. Considering that one of the features of this worm-equipment reducer may be the fact that cannot be axle-powered by the result shaft (irreversibility), it really is almost extremely hard to meet total irreversibility conditions, due to external elements such as 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 as follows:
• Efficiency < 0,55 (find table of technical features).
Maintenance
This kind of gear reducer will get a permanent lubrication, so it will 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 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.
