Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be little, but it’s difficult enough to take care of demanding ability transfer applications. Constructed with machined aluminium housings and hardened steel input and output gears, they’ll deliver many years of reliable performance.
Available in three standard output ratios and with several output shaft diameter options, it’s easy to find the EP right miniature gearbox for your needs. Each RW unit worm gear container assembly provides proportionally large 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 based on application. Also rate is increased or decreased compared index G – Equipment BOXES – on blue – smallto the speed decrease ratio. EP includes a full line of gearboxes and rate reducers, and the components needed to build them, in a wide variety of regular ratios and shaft options along with custom designs.
Helical, bevel, and miter equipment boxes offer the options of velocity reducers or acceleration increasers, and could be powered in either direction. All EP worm equipment speed reducers and right angle drives are manufactured for powerful in a large spectrum of applications. Commonly worm gear boxes aren’t used as acceleration increasers. The cases are molded glass-filled materials making them extremely tough and resilient to corrosive environments. They are offered in a wide variety of ratios and are built with right hand or left hand worm gears. The output shafts may be sturdy or hollow, and load capability is unaffected by path and rotation.
Worm gear rate reducers are comprised of a screw (the worm) that drives a steering wheel (helical gear) or solitary enveloping wheel and are used in mechanical applications which range from conveyors to exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary movement into intermittent rotary motion. The rotating drive steering wheel has a pin that reaches into a slot of the driven steering wheel advancing it by one stage and a blocking disk that locks the driven wheel constantly in place between steps.
Compact design
Compact design is among the key words of the standard gearboxes of the BJ-Series. Further optimisation can be achieved through the use of 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 equipment combined with the use of cast iron and substantial 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 apparatus. Therefore 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 typically proves to be a decisive advantage producing the incorporation of the gearbox significantly simpler and more compact.The worm gearbox can be an angle gear. This is often 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 gear house and is ideal for direct 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 will provide a self-locking effect, which in many situations can be utilized as brake or as extra security. As well spindle gearboxes with a trapezoidal spindle will be self-locking, making them perfect for a wide range of solutions.
Structural Features
The worm-gear reducer is made up of three main parts: housing, worm-gear and wheel.
The carcasses are constructed with GG-25 cast-iron, and so are available for all types of gear-reducer. This make them perform efficiently under stressed conditions, vibrations or any kind of setback that cannot be avoided through 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 high quality, excellent overall performance 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 manufactured from 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), provide 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 substitutes to the output hollow shaft with diameter 25, from size 62. This variant has like reference size 63 and is born like answer to the ask for of our costumers since, upon mounting greater bearings in the result, bears better 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 next instructions must be taken into account:
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 recommended to insert compensating couplings, connectors, torque limiters etc…
If the gear reducer needed to be painted, the oil seals should be covered to avoid them from drying and losing their seal.
The device work of the fittings create in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is wise to focus on this issue when the apparatus reducer output shaft is driven instead of being a driver. Considering that among the top features of this worm-equipment reducer is the fact that cannot be axle-powered by the result shaft (irreversibility), it is almost difficult to meet total irreversibility conditions, because of external factors such as vibrations, etc. This is why, when the application needs total irreversibility, it is advisable to make use of external brakes with enough power to avoid slipping.
It may be said that the conditions under which irreversibility can occur are as follows:
• Efficiency < 0,55 (find table of specialized features).
Maintenance
This type of gear reducer is provided with a permanent lubrication, so that it will not need any kind 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 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.
