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 metal input and result gears, they’ll deliver a long time of reliable performance.
Obtainable 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 (maximum 2° backlash).

Mechanical drives take supplied torque and could 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 has a full line of gearboxes and swiftness reducers, and the components needed to build them, in an array of regular ratios and shaft options as well as custom designs.
Helical, bevel, and miter gear boxes provide options of speed reducers or rate increasers, and may be driven in either path. All Ever-Power worm equipment speed reducers and correct angle drives are produced for high performance in a large spectral range of applications. Typically worm equipment boxes aren’t used as velocity increasers. The instances are molded glass-filled materials making them extremely tough and resistant to corrosive conditions. They can be found in a wide selection of ratios and are equipped with right hands or left hand worm gears. The output shafts could be solid or hollow, and load capability is unaffected by direction and rotation.
Worm gear swiftness reducers are made up of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and are found in mechanical applications ranging from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary motion into intermittent rotary motion. The rotating drive wheel has a pin that gets to right into a slot of the powered wheel advancing it by one stage and a blocking disc that locks the powered wheel in position between steps.
Compact design
Compact design is among the key phrases of the typical 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 due to the very smooth running of the worm gear combined with the utilization of cast iron and high precision on element manufacturing and assembly. In connection with our precision gearboxes, we take extra care of any sound that can be interpreted as a murmur from the apparatus. Therefore the general noise level of our gearbox is usually reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This frequently proves to become a decisive advantage making the incorporation of the gearbox considerably simpler and more compact.The worm gearbox is 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 gear house and is perfect for immediate 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 impact, which in many circumstances can be utilized as brake or as extra security. 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 comprises of three main parts: housing, worm-gear and wheel.
The carcasses are made of GG-25 cast-iron, and are available for all sorts of gear-reducer. This make them perform efficiently 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 manufactured from DIN (GZ-CuSn 12 Ni2) centricast bronze, melted on steel. Due to the mechanical work of the two parts having high quality, excellent efficiency and low noise amounts 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), supply 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 exists like response to the request of our costumers since, upon mounting higher bearings in the result, bears higher axial loads that its analogous one in the MF-62 series. The others of technical characteristic are identical to the its analogous in the size 62.
Assembly Position
In order to create 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 gear reducer had to be painted, the oil seals must be covered to prevent 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 wise to pay attention to this factor when the gear reducer output shaft is driven rather than being a driver. Bearing in mind that among the top features of this worm-gear reducer is the fact that can’t be axle-driven by the output shaft (irreversibility), it really is almost extremely hard to meet total irreversibility conditions, due to external factors such as vibrations, etc. For this reason, when the application form requires total irreversibility, it really is advisable to utilize exterior brakes with enough power to avoid slipping.
It could be said that the circumstances under which irreversibility can happen are as follows:
• Efficiency < 0,55 (see table of specialized 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 the 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 isn’t needed.
