Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be small, but it’s challenging enough to handle demanding power transfer applications. Designed with machined aluminum housings and hardened steel input and output gears, they’ll deliver many years of reliable performance.
Obtainable in three standard result ratios and with two output shaft diameter options, it’s easy to find the Ever-Power right miniature gearbox to your requirements. Each RW model worm equipment box 
assembly provides proportionally high torque values (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 rate is increased or reduced compared index G – Equipment BOXES – on blue – smallto the speed reduction ratio. Ever-Power has a full type of gearboxes and rate reducers, and the elements 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 provide options of velocity reducers or velocity increasers, and could be driven in either path. All Ever-Power worm equipment speed reducers and right angle drives are manufactured for powerful in a large spectrum of applications. Typically worm gear boxes are not used as acceleration increasers. The situations are molded glass-filled material making them extremely tough and resistant to corrosive environments. They can be found in a wide range of ratios and are equipped with right hand or left hand worm gears. The output shafts may be solid or hollow, and load capacity is unaffected by path and rotation.
Worm gear quickness reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or solitary enveloping wheel and are found in mechanical applications ranging from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary movement into intermittent rotary motion. The rotating drive wheel has a pin that gets to right into a slot of the powered wheel advancing it by one step and a blocking disc that locks the driven wheel in position between steps.
Compact design
Compact design is one of 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 running of the worm gear combined with the usage of cast iron and high precision on element manufacturing and assembly. In connection with our precision gearboxes, we take extra treatment of any sound which can be interpreted as a murmur from the gear. So the general noise level of our gearbox is usually 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 smaller sized.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 well suited for direct suspension for wheels, movable arms and other parts rather than having to build a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes will provide a self-locking effect, 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 well suited for a wide selection of solutions.
Structural Features
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are made of GG-25 cast-iron, and are available for all types of gear-reducer. This make sure they are perform effectively under stressed conditions, vibrations or any type of setback that can’t be avoided through the assembly
The worm-gear is made from 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. Because of the mechanical work of these two parts having top quality, excellent efficiency and low noise levels have been achived.
The output shaft is hollow, although it is possible to adapt a solid 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 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 offers like reference size 63 and is born like answer to the request of our costumers since, upon mounting better bearings in the output, bears better axial loads that its analogous one in the MF-62 series. The others of technical feature are identical to the its analogous in the size 62.
Assembly Position
In order to create a gear reducer and also to make it work efficiently, the next instructions must be considered:
It must be fixed on a flat 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 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 need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this element when the gear reducer result shaft is driven rather than being a driver. Bearing in mind that one of the top features of this worm-gear reducer is the fact that cannot be axle-driven by the result shaft (irreversibility), it really is almost impossible to meet total irreversibility conditions, due to external factors such as for example vibrations, etc. This is why, when the application form needs total irreversibility, it is advisable to make use of exterior brakes with enough capacity to avoid slipping.
It may be said that the circumstances under which irreversibility can occur are the following:
• Efficiency < 0,55 (discover table of technical features).
Maintenance
This type of gear reducer is provided with 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 has 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 isn’t needed.
