Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be little, but it’s challenging enough to handle demanding power transfer applications. Constructed with machined light weight aluminum housings and hardened steel input and result gears, they’ll deliver a long time of reliable performance.
Available in three standard result ratios and with two result shaft diameter options, it’s easy to find the Ever-Power correct miniature gearbox to your requirements. Each RW model worm gear box assembly provides proportionally high torque ideals (1.4 NM at 3,000 RPM) with very low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque predicated on application. Also speed is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed reduction ratio. Ever-Power has a full line of gearboxes and rate 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 quickness reducers or rate increasers, and may be driven in either direction. All Ever-Power worm equipment speed reducers and correct angle drives are produced for high performance in a large spectrum of applications. Typically worm gear boxes are not used as speed increasers. The situations are molded glass-filled materials making them extremely rugged and resistant to corrosive environments. They can be found in a wide selection of ratios and are equipped with right hand or left hand worm gears. The result shafts may be solid or hollow, and load capability is unaffected by path and rotation.
Worm gear acceleration reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or one enveloping wheel and are used in mechanical applications ranging from conveyors to exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary motion into intermittent rotary motion. The rotating drive wheel includes a pin that gets to 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 one of the key phrases of the standard gearboxes of the BJ-Series. Further optimisation can be achieved by using adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is due to 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 treatment of any sound that can be interpreted as a murmur from the gear. Therefore 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 one another. This frequently proves to become a decisive advantage making the incorporation of the gearbox substantially simpler and smaller sized.The worm gearbox is 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 gear house and is perfect for direct suspension for wheels, movable arms and other parts rather than having to create 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 used as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them well suited for a wide range of solutions.
Structural Features
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are made from GG-25 cast-iron, and so are available for all sorts of gear-reducer. This make sure they are perform effectively under stressed conditions, vibrations or any type of setback that can’t be avoided during the assembly
The worm-gear is made from 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 these two parts having top quality, excellent performance and low noise levels have been achived.
The output shaft is hollow, although it is possible 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), provide the most competitive gear reducer out there.
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 is born like answer to the demand of our costumers since, upon mounting greater bearings in the result, bears greater 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 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 recommended to insert compensating couplings, connectors, torque limiters etc…
If the gear reducer needed to be painted, the essential oil seals should be covered to avoid them from drying and losing their seal.
The device work of the fittings create in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to focus on this factor when the gear reducer output shaft is driven rather than being a driver. Considering that among the top features of this worm-gear reducer is the fact that cannot be axle-powered by the result shaft (irreversibility), it really is almost impossible to meet up total irreversibility conditions, because of external elements such as vibrations, etc. For this reason, when the application form needs total irreversibility, it is advisable to utilize 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 (discover table of technical features).
Maintenance
This type of gear reducer will get a permanent lubrication, so that it really does not need any type of maintenance.
Lubrication
The lubrication of this gear reducer type is continuous and comes as standard, with high quality refined oil which has 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 isn’t needed.
