Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be little, but it’s hard 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 many years 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 for your needs. Each RW model worm equipment container assembly provides proportionally high torque values (1.4 NM at 3,000 RPM) with very low backlash (maximum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque based on application. Also velocity 
is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed decrease ratio. Ever-Power includes a full type of gearboxes and acceleration reducers, and the elements had a need to build them, in a wide range of standard ratios and shaft options as well as custom designs.
Helical, bevel, and miter equipment boxes provide options of swiftness reducers or rate increasers, and may be driven in either path. All Ever-Power worm gear speed reducers and right angle drives are manufactured for powerful in a large spectrum of applications. Typically worm gear boxes are not used as swiftness increasers. The cases are molded glass-filled materials making them extremely tough and resistant to corrosive environments. They can be found in an array of ratios and are built with right hand or left hands worm gears. The output shafts may be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear rate reducers are made up of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and so are found in mechanical applications which range from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary motion into intermittent rotary movement. The rotating drive wheel includes a pin that gets to 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 among the key phrases of the typical 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 due to the very smooth operating of the worm gear combined with the usage of cast iron and high precision on component manufacturing and assembly. Regarding the 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 certainly 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 making the incorporation of the gearbox significantly simpler and more compact.The worm gearbox is 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 gear house and is ideal for immediate suspension for wheels, movable arms and other areas rather than having to create a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes provides a self-locking impact, which in many situations can be utilized as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them perfect for an array 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 circumstances, vibrations or any kind of setback that cannot be avoided through the assembly
The worm-gear is constructed of 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 these two parts having high quality, excellent functionality and low sound amounts have been achived.
The output shaft is hollow, though it is possible to adapt a solid 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 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 is born like answer to the ask for of our costumers since, upon mounting better bearings in the output, bears higher 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 setup a gear reducer and also to make it work efficiently, the following instructions must be taken into account:
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 apparatus reducer needed to be painted, the essential oil seals should be covered to avoid them from drying and losing their seal.
The machine work of the fittings setup in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this aspect when the gear reducer result shaft is driven instead of being a driver. Considering that among the top features of this worm-equipment reducer is the fact that can’t be axle-powered by the output shaft (irreversibility), it really is almost impossible to meet total irreversibility conditions, due to external factors such as for example vibrations, etc. That is why, when the application requires total irreversibility, it is advisable to utilize external brakes with enough capacity to avoid slipping.
It could be said that the circumstances under which irreversibility can happen are as follows:
• Efficiency < 0,55 (discover table of technical 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 continuous and comes as standard, with top 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 isn’t needed.
