Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be little, but it’s tough enough to take care of demanding power transfer applications. Constructed with machined aluminum housings and hardened metal input and output gears, they’ll deliver many years of reliable performance.
Available in three standard output ratios and with two result shaft diameter options, it’s simple to find the Ever-Power correct miniature gearbox for your needs. Each RW model worm equipment package 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 based on application. Also rate is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed decrease ratio. Ever-Power has a full type of gearboxes and acceleration reducers, and the components had a need to build them, in a wide range of regular ratios and shaft choices and also custom designs.
Helical, bevel, and miter equipment boxes offer the options of quickness reducers or velocity increasers, and may be powered in either direction. All Ever-Power worm equipment speed reducers and right angle drives are manufactured for powerful in a large spectral range of applications. Typically worm gear boxes aren’t used as rate increasers. The instances are molded glass-filled material making them extremely tough and resistant to corrosive environments. They can be found in an array of ratios and are built with right hands or left hands worm gears. The result shafts may be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear rate reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or one 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 motion into intermittent rotary motion. The rotating drive wheel has a pin that reaches right into a slot of the driven wheel advancing it by one stage and a blocking disc that locks the powered wheel in position between steps.
Compact design
Compact design is one of the key terms of the standard gearboxes of the BJ-Series. Further optimisation can be achieved through the use of adapted gearboxes or unique gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth working of the worm equipment combined with the utilization of cast iron and high precision on element 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. So the general noise degree of our gearbox is 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 be a decisive advantage producing the incorporation of the gearbox substantially simpler and smaller sized.The worm gearbox can be an angle gear. This is an edge for incorporation into constructions.
Strong bearings in solid housing
The output shaft of the BJ worm gearbox is quite firmly embedded in the apparatus house and is well suited for immediate suspension for wheels, movable arms and other parts rather than having to create a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes will provide a self-locking impact, 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 perfect for a wide variety 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 are available for all kinds of gear-reducer. This make them perform efficiently under stressed circumstances, vibrations or any kind of setback that cannot be avoided through 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. Due to the mechanical work of the two parts having high quality, excellent functionality and low sound amounts have been achived.
The output shaft is hollow, although it can be done to adapt a good shaft.
The oil seals made of 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 most competitive gear reducer in the marketplace.
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 has like reference size 63 and is born like response 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 others of technical characteristic are identical 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 should 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 suggested to insert compensating couplings, connectors, torque limiters etc…
If the gear reducer needed to be painted, the oil seals should be covered to avoid 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 smart to pay attention to this aspect when the gear reducer result shaft is driven rather than being a driver. Bearing in mind that one of the features of this worm-equipment reducer may be the fact that can’t be axle-powered by the result shaft (irreversibility), it really is almost difficult to meet up total irreversibility conditions, due to external elements such as vibrations, etc. For this reason, when the application form needs total irreversibility, it really is advisable to make use of exterior brakes with enough power to avoid slipping.
It may be said that the circumstances under which irreversibility can occur are as follows:
• Efficiency < 0,55 (find table of specialized features).
Maintenance
This sort of gear reducer is provided with 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 which has level of quality CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; because of this its maintenance is not needed.
