Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be small, but it’s challenging enough to handle demanding power transfer applications. Designed with machined aluminum housings and hardened steel input and output gears, they’ll deliver many years 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 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 may increase or reduce that torque predicated on application. Also velocity is increased or reduced in proportion index G – GEAR BOXES – on blue – smallto the speed reduction ratio. Ever-Power includes a full line of gearboxes and swiftness reducers, and the parts had a need to build them, in an array of regular ratios and shaft choices and also custom designs.
Helical, bevel, and miter equipment boxes provide options of swiftness reducers or quickness increasers, and may be driven in either path. All Ever-Power worm equipment speed reducers and right angle drives are produced for powerful in a large spectrum of applications. Typically worm equipment boxes aren’t used as rate increasers. The instances are molded glass-filled material making them extremely durable and resistant to corrosive environments. They are offered in a wide variety of ratios and are built with right hand or left hand worm gears. The result shafts may be solid or hollow, and load capacity is unaffected by direction 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 usually used to transform continuous rotary motion into intermittent rotary movement. The rotating drive wheel includes a pin that gets to right into a slot of the driven 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 one of the key phrases of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes 
or unique gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is because of the very smooth operating of the worm gear combined with the use of cast iron and high precision on element manufacturing and assembly. In connection with our precision gearboxes, we consider extra treatment of any sound that can be interpreted as a murmur from the gear. So the general noise degree of our gearbox is definitely 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 making the incorporation of the gearbox significantly 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 well suited for immediate suspension for wheels, movable arms and other areas 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 used as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited for a wide selection of solutions.
Structural Features
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are made of GG-25 cast-iron, and so are available for all sorts of gear-reducer. This make sure they are perform effectively under stressed circumstances, vibrations or any kind of setback that can’t be avoided through the assembly
The worm-gear is constructed 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. Because of the mechanical work of the two parts having top quality, excellent overall performance 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 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 provides like reference size 63 and exists like answer to the demand 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 rest of technical characteristic are similar to the its analogous in the size 62.
Assembly Position
In order to setup a gear reducer and also to make it work efficiently, the following instructions must be considered:
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 recommended to insert compensating couplings, connectors, torque limiters etc…
If the apparatus reducer had to be painted, the essential oil seals must be covered to prevent them from drying and losing their seal.
The device work of the fittings set up in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this aspect when the apparatus reducer result shaft is driven instead of being a driver. Considering that among the top features of this worm-gear reducer is the fact that can’t be axle-driven by the result shaft (irreversibility), it really is almost difficult to meet up total irreversibility conditions, because of external factors such as for example vibrations, etc. This is why, when the application requires total irreversibility, it really is advisable to make use of exterior brakes with enough capacity to avoid slipping.
It could be said that the circumstances under which irreversibility can occur are as follows:
• Efficiency < 0,55 (discover table of technical features).
Maintenance
This sort of gear reducer will get a permanent lubrication, so it really does not need any kind of maintenance.
Lubrication
The lubrication of the gear reducer type is constant and comes as standard, with high 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.
