Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be small, but it’s tough enough to handle demanding power transfer applications. Constructed with machined 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 right miniature gearbox for your needs. Each RW model worm gear package assembly provides proportionally high torque ideals (1.4 NM at 3,000 RPM) with suprisingly 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 compared index G – GEAR BOXES – on blue – smallto the speed decrease ratio. Ever-Power has a full type of gearboxes and quickness reducers, and the parts had a need to build them, in a wide range of standard ratios and shaft options and also custom designs.
Helical, bevel, and miter equipment boxes offer the options of swiftness reducers or acceleration increasers, and may be powered in either direction. All Ever-Power worm gear speed reducers and correct angle drives are produced for powerful in a large spectrum of applications. Typically worm gear boxes aren’t used as acceleration increasers. The cases are molded glass-filled materials making them extremely tough and resistant to corrosive conditions. They can be found in a wide range of ratios and are equipped with right hands or left hand worm gears. The result shafts may be solid or hollow, and load capacity is unaffected by direction and rotation.
Worm gear quickness reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and are used in mechanical applications which range from conveyors to workout devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary motion into intermittent rotary motion. The rotating drive wheel includes a pin that reaches into a slot of the powered wheel advancing it by one step and a blocking disc that locks the driven wheel constantly in place between steps.
Compact design
Compact design is among the key words 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 really quiet. This is because of the very smooth operating of the worm equipment combined with the utilization of cast iron and high precision on element manufacturing and assembly. In connection with our precision gearboxes, we consider extra care of any sound which can be interpreted as a murmur from the gear. Therefore the general noise level of our gearbox is certainly reduced to a complete 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 can be 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 apparatus house and is well suited 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 provides a self-locking impact, which in many circumstances can be utilized 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 comprises of three main parts: housing, worm-gear and wheel.
The carcasses are constructed with GG-25 cast-iron, and are available for all kinds of gear-reducer. This make sure they are perform effectively under stressed circumstances, 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 these two parts having top quality, excellent efficiency and low noise amounts have been achived.
The output shaft is hollow, though it can be done to adapt a good shaft.
The oil seals made of 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 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 worm gear box assembly substitutes to the output hollow shaft with diameter 25, from size 62. This variant provides like reference size 63 and is born 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 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 taken into account:
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 suggested to insert compensating couplings, connectors, torque limiters etc…
If the gear reducer had to be painted, the oil seals should be covered to prevent them from drying and losing their seal.
The device work of the fittings set up in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to pay attention to this element when the gear reducer result shaft is driven rather than being a driver. Considering that among the top features of this worm-equipment reducer may be the fact that can’t be axle-driven by the result shaft (irreversibility), it is almost extremely hard to meet up total irreversibility conditions, because of external elements such as vibrations, etc. That is why, when the application requires 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 (find table of specialized features).
Maintenance
This type of gear reducer will get a permanent lubrication, so it will 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 includes antirust and antiwear products with Fe, Cu and alloy protectors that has quality level CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; because of this its maintenance isn’t needed.
