Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be small, but it’s difficult enough to take care of demanding power transfer applications. Constructed with machined aluminium housings and hardened metal input and output 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 simple to find the Ever-Power correct miniature gearbox to your requirements. Each RW model worm equipment box assembly provides proportionally high torque ideals (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 based on application. Also swiftness is increased or decreased in proportion index G – Equipment BOXES – on blue – smallto the speed decrease ratio. Ever-Power includes a full line of gearboxes and quickness reducers, and the parts had a need to build them, in an array of regular ratios and shaft choices along with custom designs.
Helical, bevel, and miter equipment boxes offer the options of quickness reducers or quickness increasers, and could be driven in either direction. All Ever-Power worm equipment speed reducers and correct angle drives are manufactured for powerful in a large spectrum of applications. Typically worm equipment boxes aren’t used as speed increasers. The instances are molded glass-filled material making them extremely tough and resistant to corrosive conditions. They can be found in a wide range of ratios and are built with right hands or left hand worm gears. The result shafts could be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear velocity reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and are found in mechanical applications which range from conveyors to exercise devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary movement into intermittent rotary movement. The rotating drive wheel has a pin that reaches into a slot of the driven wheel worm gear box assembly advancing it by one stage and a blocking disc that locks the powered wheel constantly in place between steps.
Compact design
Compact design is one of the key words of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or special 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 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 apparatus. So 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 often proves to be a decisive advantage making the incorporation of the gearbox substantially simpler and smaller sized.The worm gearbox is an angle gear. This is an edge 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 needing to build a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes provides a self-locking impact, which in many situations 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 is made up 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 efficiently under stressed conditions, vibrations or any kind of setback that can’t be avoided during the assembly
The worm-gear is made 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 high quality, excellent functionality and low noise levels 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, high quality bearings, an EPOXY- impregnated finish ( 2 components), and grey-coloured SINGLE LAYER ENAMEL finish ( 2 components) ( RAL 7672), provide the best 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 answer to the request 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 others 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 happen efficiently, the following instructions must be considered:
It must be fixed on a set 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 essential oil seals should be covered to prevent them from drying and losing their seal.
The machine work of the fittings create in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to pay attention to this element when the gear reducer result shaft is driven rather than being a driver. Considering that among 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 extremely hard to meet total irreversibility conditions, due to external elements such as for example vibrations, etc. For this reason, when the application needs total irreversibility, it really is advisable to utilize external brakes with enough capacity to avoid slipping.
It may be said that the conditions under which irreversibility can happen are the following:
• Efficiency < 0,55 (observe table of specialized features).
Maintenance
This sort 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 includes 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 is not needed.
