Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be small, but it’s tough enough to handle demanding power transfer applications. Constructed with machined light weight aluminum housings and hardened metal input and output 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 right miniature gearbox to your requirements. Each RW model worm gear package assembly provides proportionally high torque ideals (1.4 NM at 3,000 RPM) with very low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque based on application. Also speed 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 speed reducers, and the components needed 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 swiftness increasers, and may be driven in either path. All Ever-Power worm gear speed reducers and correct angle drives are manufactured for powerful in a large spectral range of applications. Typically worm gear boxes aren’t used as velocity increasers. The cases are molded glass-filled material making them extremely rugged and resistant to corrosive conditions. They are offered in a wide variety 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 swiftness reducers are comprised of a screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and so are found in mechanical applications ranging from conveyors to workout 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 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 terms of the standard gearboxes of the BJ-Series. Further optimisation can be achieved by using adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth operating 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 take extra treatment of any sound that can be interpreted as a murmur from the gear. So the general noise degree 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 often proves to become a decisive advantage producing the incorporation of the gearbox significantly simpler and smaller sized.The worm gearbox can be an angle gear. This is often 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 direct suspension for wheels, movable arms and other parts 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 circumstances can be used 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 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 type of setback that cannot be avoided during the assembly
The worm-gear is made 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. Because of the mechanical work of the two parts having top quality, excellent efficiency and low noise levels have been achived.
The output shaft is hollow, although it can be done 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 best 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 substitutes to the output hollow shaft with diameter 25, from size 62. This variant provides like reference size 63 and is born like answer to the demand of our costumers since, upon mounting higher bearings in the output, bears better 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 also to make it happen efficiently, the following instructions must be taken into account:
It should 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 gear reducer needed to be painted, the oil seals must be covered to avoid them from drying and losing their seal.
The device work of the fittings setup in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to focus on this factor when the apparatus reducer output shaft is driven instead of being a driver. Bearing in mind that one of the features of this worm-equipment reducer is the fact that cannot be axle-driven by the output shaft (irreversibility), it is almost unattainable to meet total irreversibility conditions, because of external factors such as vibrations, etc. This is why, when the application needs total irreversibility, it really is advisable to utilize exterior brakes with enough capacity to avoid slipping.
It may be said that the conditions under which irreversibility can occur are as follows:
• Efficiency < 0,55 (observe table of technical features).
Maintenance
This sort of gear reducer will get a permanent lubrication, so that it really does 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 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.
