Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be little, but it’s hard enough to handle demanding power transfer applications. Constructed with machined aluminium housings and hardened steel input and result gears, they’ll deliver many years of reliable performance.
Available in three standard output ratios and with two result shaft diameter options, it’s easy to find the Ever-Power right miniature gearbox for your needs. Each RW model worm gear package assembly provides proportionally high torque values (1.4 NM at 3,000 RPM) with suprisingly low backlash (maximum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque predicated on application. Also velocity is increased or decreased compared index G – Equipment BOXES – on blue – smallto the speed decrease ratio. Ever-Power has a full line of gearboxes and rate reducers, and the components needed 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 speed reducers or acceleration 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 spectral range of applications. Typically worm equipment boxes are not used as velocity increasers. The situations are molded glass-filled materials making them extremely durable and resistant to corrosive conditions. They are offered 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 capability is unaffected by direction and rotation.
Worm gear rate reducers are made up 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 physical exercise devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary movement into intermittent rotary motion. The rotating drive wheel has a pin that reaches right into a slot of the powered 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 phrases of the typical gearboxes of the BJ-Series. Further optimisation may be accomplished through the use of 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 gear combined with the use of cast iron and high precision on component manufacturing and assembly. Regarding the our precision gearboxes, we take extra treatment of any sound that can be interpreted as a murmur from the apparatus. Therefore the general noise degree of our gearbox is 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 be a decisive advantage making the incorporation of the gearbox considerably simpler and more compact.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 very 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 gear ratios,EP-Gear’s worm gearboxes provides 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 well suited for an array of solutions.
Structural Features
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are constructed with GG-25 cast-iron, and so 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 can’t be avoided through the assembly
The worm-gear is made 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. Due to the mechanical work of these two parts having top quality, excellent efficiency and low noise amounts 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), 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 answer to the ask for of our costumers since, upon mounting greater bearings in the result, bears better axial loads that its 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 create a gear reducer and to make it work efficiently, the following instructions must be taken into account:
It must 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 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 need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to pay attention to this factor when the apparatus reducer result shaft is driven rather than being a driver. Bearing in mind that one of the features of this worm-gear reducer is the fact that can’t be axle-powered by the result shaft (irreversibility), it really is almost impossible to meet up total irreversibility conditions, due to external factors such as vibrations, etc. This is why, when the application form requires total irreversibility, it really is advisable to make use of external brakes with enough power to avoid slipping.
It could be said that the conditions under which irreversibility can happen are as follows:
• 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 type of maintenance.
Lubrication
The lubrication of the 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 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.
