Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be small, but it’s hard enough to handle demanding power transfer applications. Constructed with machined aluminum 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 box assembly provides proportionally high 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 predicated on application. Also rate is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed decrease ratio. Ever-Power includes 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 options and also custom designs.
Helical, bevel, and miter equipment boxes provide options of velocity reducers or speed increasers, and may be powered in either path. All Ever-Power worm gear speed reducers and right angle drives are produced for high performance in a large spectrum of applications. Typically worm gear boxes are not used as quickness increasers. The cases are molded glass-filled material making them extremely rugged and resistant to corrosive environments. They can be found in a wide selection of ratios and are built with right hand or left hands worm gears. The result shafts could be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear quickness reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and so 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 movement. The rotating drive wheel has a pin that reaches right into a slot of the driven wheel advancing it by one stage and a blocking disc that locks the powered wheel in position between steps.
Compact design
Compact design is one of the key terms of the standard 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 due to the very smooth working of the worm gear combined with the use of cast iron and high precision on component manufacturing and assembly. Regarding the our precision gearboxes, we take extra care of any sound that can be interpreted as a murmur from the gear. So 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 each other. This often proves to become a decisive advantage producing the incorporation of the gearbox significantly simpler and more compact.The worm gearbox can be an angle gear. This is often an advantage for incorporation into constructions.
Solid bearings in solid housing
The output shaft of the BJ worm gearbox is quite firmly embedded in the apparatus house and is ideal for direct suspension for wheels, movable arms and other parts rather than having to build 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 utilized as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them ideal for a wide range 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 kinds 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 these two parts having high quality, excellent functionality and low sound levels have been achived.
The output shaft is hollow, though it can be done to adapt a solid shaft.
The oil seals manufactured from NITRILE BUTADIENE, according to DIN 3760, high 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 in the marketplace.
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 is born like answer to the ask for of our costumers since, upon mounting greater bearings in the result, bears higher axial loads that its analogous one in the MF-62 series. The others of technical feature are similar to the its analogous in the size 62.
Assembly Position
In order to create a gear reducer and to make it work efficiently, the next instructions must be considered:
It should 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 essential oil seals should be covered to prevent them from drying and losing their seal.
The device work of the fittings setup in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this element when the gear reducer output shaft is driven instead of being a driver. Considering that one of the features of this worm-gear reducer is the fact that cannot be axle-driven by the result shaft (irreversibility), it is almost unattainable to meet up total irreversibility conditions, because of external factors such as for example vibrations, etc. For this reason, 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 conditions under which irreversibility can occur are as follows:
• Efficiency < 0,55 (observe table of technical features).
Maintenance
This type of gear reducer is provided with a permanent lubrication, so it really 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 includes antirust and antiwear products with Fe, Cu and alloy protectors that has level of quality CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; because of this its maintenance is not needed.
