Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment 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 output gears, they’ll deliver many years of reliable performance.
Available in three standard result ratios and with two result shaft diameter options, it’s simple to find the Ever-Power correct miniature gearbox for your needs. Each RW model worm gear box assembly provides proportionally high torque values (1.4 NM at 3,000 RPM) with suprisingly low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque based on application. Also velocity is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed reduction ratio. Ever-Power includes a full line of gearboxes and acceleration reducers, and the elements had a need to build them, in a wide range of regular ratios and shaft options in addition to custom designs.
Helical, bevel, and miter gear boxes offer the options of speed reducers or rate increasers, and could be powered in either direction. All Ever-Power worm gear speed reducers and right angle drives are produced for powerful in a large spectrum of applications. Typically worm gear boxes aren’t used as speed increasers. The instances are molded glass-filled materials making them extremely durable and resistant to corrosive conditions. They can be found in an array of ratios and are built with right hands or left hands worm gears. The result shafts could be solid or hollow, and load capacity is unaffected by path and rotation.
Worm gear swiftness reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and so are found in mechanical applications ranging from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary motion into intermittent rotary movement. The rotating drive wheel includes a pin that reaches right into a slot of the powered wheel advancing it by one step and a blocking disc that locks the driven wheel constantly in place 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 extremely 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. Regarding the our precision gearboxes, we consider extra treatment of any sound that can be interpreted as a murmur from the gear. Therefore the general noise level 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 frequently proves to become a decisive advantage making the incorporation of the gearbox substantially simpler and more compact.The worm gearbox can be 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 gear house and is ideal for immediate suspension for wheels, movable arms and other areas rather than needing to build a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes will provide a self-locking effect, which in many situations can be utilized as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited for a wide variety 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 can’t 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 these two parts having high quality, excellent overall performance and low sound levels have been achived.
The output shaft is hollow, although it can be done 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 has like reference size 63 and exists like response to the ask for 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 similar to the its analogous in the size 62.
Assembly Position
In order to set up a gear reducer and also to make it happen efficiently, the next instructions must be considered:
It must be fixed on a flat surface in order 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 apparatus reducer had to be painted, the oil seals should be covered to avoid them from drying and losing their seal.
The machine 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 factor when the gear reducer output shaft is driven instead of being a driver. Considering that one of the features of this worm-gear reducer may be the fact that cannot be axle-driven by the output shaft (irreversibility), it is almost not possible to meet total irreversibility conditions, because of external factors such as vibrations, etc. That is why, when the application requires total irreversibility, it really 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 as follows:
• Efficiency < 0,55 (see table of specialized features).
Maintenance
This sort 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 top 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; because of this its maintenance isn’t needed.
