Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be small, but it’s difficult enough to handle demanding power transfer applications. Constructed with machined aluminum housings and hardened metal input and output gears, they’ll deliver a long time of reliable performance.
Obtainable in three standard output ratios and with two output shaft diameter options, it’s simple to find the Ever-Power right miniature gearbox for your needs. Each RW model worm gear package 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 could increase or reduce that torque based on application. Also velocity is increased or decreased compared index G – GEAR BOXES – on blue – smallto the speed decrease ratio. Ever-Power includes a full type of gearboxes and quickness reducers, and the elements needed to build them, in a wide variety of standard ratios and shaft choices in addition to custom designs.
Helical, bevel, and miter gear boxes offer the options of speed reducers or swiftness increasers, and could be powered in either path. All Ever-Power worm gear speed reducers and right angle drives are manufactured for powerful in a large spectral range of applications. Typically worm equipment boxes aren’t used as acceleration increasers. The instances are molded glass-filled material making them extremely durable and resistant to corrosive conditions. They are offered in an array of ratios and are equipped with right hands or left hands worm gears. The output shafts could be solid or hollow, and load capacity 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 solitary enveloping wheel and so are found in mechanical applications which range from conveyors to physical 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 right into a slot of the driven wheel advancing it by one step and a blocking disc that locks the powered wheel in position between steps.
Compact design
Compact design is among the key words of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished through the use of adapted gearboxes or unique gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth working of the worm gear combined with the utilization of cast iron and high precision on component 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. So the general noise level of our gearbox is usually reduced to a complete 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 considerably simpler and more compact.The worm gearbox is an angle gear. This is often 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 apparatus house and is well suited for immediate suspension for wheels, movable arms and other areas rather than needing to build 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 utilized as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle are self-locking, making them ideal 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 of GG-25 cast-iron, and so are available for all types of gear-reducer. This make them 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 the two parts having high quality, excellent overall performance and low sound 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, 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 on the market.
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 exists like response to the ask for of our costumers since, upon mounting greater bearings in the output, 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 set up a gear reducer and to make it happen efficiently, the next instructions must be taken into account:
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 recommended to insert compensating couplings, connectors, torque limiters etc…
If the apparatus 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 set up in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this element when the apparatus reducer result shaft is driven instead of 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-driven by the output shaft (irreversibility), it is almost not possible to meet total irreversibility conditions, due to external factors such as vibrations, etc. This is why, when the application needs total irreversibility, it really is advisable to make use of external brakes with enough capacity to avoid slipping.
It could be said that the circumstances under which irreversibility can happen are the following:
• Efficiency < 0,55 (see table of specialized features).
Maintenance
This kind of gear reducer is provided with a permanent lubrication, so it will not need any kind 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 which has quality level CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; for that reason its maintenance is not needed.
