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 light weight aluminum housings and hardened steel input and output gears, they’ll deliver a long time of reliable performance.
Obtainable in three standard output ratios and with two result shaft diameter options, it’s simple to find the Ever-Power right miniature gearbox for your needs. Each RW model worm equipment container assembly provides proportionally high torque ideals (1.4 NM at 3,000 RPM) with suprisingly low backlash (maximum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque predicated on application. Also speed is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed reduction ratio. Ever-Power has a full line of gearboxes and acceleration reducers, and the elements had a need to build them, in a wide variety of standard ratios and shaft choices as well as custom designs.
Helical, bevel, and miter equipment boxes offer the options of acceleration reducers or velocity increasers, and may be powered in either path. All Ever-Power worm equipment speed reducers and right angle drives are manufactured for high performance in a large spectrum of applications. Typically worm gear boxes aren’t used as swiftness increasers. The situations are molded glass-filled materials making them extremely rugged and resistant to corrosive conditions. They are offered in a wide range of ratios and are equipped with right hand or left hand worm gears. The output shafts could be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear speed reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and are used in mechanical applications which range from conveyors to 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 constantly in place between steps.
Compact design
Compact design is among 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 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 element manufacturing and assembly. Regarding the our precision gearboxes, we consider extra care of any sound which can be interpreted as a murmur from the apparatus. Therefore the general noise level of our gearbox is certainly reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This often proves to become a decisive advantage producing the incorporation of the gearbox significantly simpler and smaller sized.The worm gearbox is an angle gear. This is often 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 gear house and is ideal for direct suspension for wheels, movable arms and other areas rather than having 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 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 so are available for all kinds of gear-reducer. This make them perform effectively under stressed circumstances, vibrations or any kind of setback that can’t 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 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 made of 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 best 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, upon mounting better bearings in the output, bears higher axial loads that its worm gear box assembly analogous one in the MF-62 series. The rest of technical feature are similar to the its analogous in the size 62.
Assembly Position
In order to setup a gear reducer and to make it happen efficiently, the next instructions must be considered:
It should be fixed on a flat 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 apparatus reducer needed to be painted, the essential 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 require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this element when the apparatus reducer result shaft is driven rather than being a driver. Considering that one of the 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 extremely hard to meet up total irreversibility conditions, because of external elements such as for example vibrations, etc. This is why, when the application needs total irreversibility, it is advisable to make use of exterior 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 (discover table of specialized features).
Maintenance
This sort of gear reducer is provided with a permanent lubrication, so that it does not need any type 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.
