Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be little, but it’s difficult enough to handle demanding power transfer applications. Designed with machined aluminum housings and hardened metal input and result gears, they’ll deliver a long time of reliable performance.
Obtainable in three standard output ratios and with several output shaft diameter options, it’s simple to find the EP correct miniature gearbox to your requirements. Each RW version worm gear container assembly provides proportionally excessive torque ideals (1.4 NM at 3,000 RPM) with very low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque based on application. Also quickness is increased or reduced compared index G – Equipment BOXES – on blue – smallto the speed decrease ratio. EP includes a full line of gearboxes and swiftness reducers, and the components needed to build them, in an array of standard ratios and shaft choices in addition to custom designs.
Helical, bevel, and miter gear boxes offer the options of rate reducers or acceleration increasers, and could be driven in either direction. All EP worm equipment speed reducers and right angle drives are produced for high performance in a large spectrum of applications. Commonly worm gear boxes aren’t used as quickness increasers. The situations are molded glass-filled material making them extremely tough and tolerant to corrosive conditions. They are offered in a wide variety of ratios and are built with right hands or left hands worm gears. The output shafts may be stable or hollow, and load capacity is unaffected by path and rotation.
Worm gear rate reducers are comprised of a good screw (the worm) that drives a steering 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 motion into intermittent rotary movement. The rotating drive steering wheel has a pin that reaches into a slot of the powered steering wheel advancing it by one stage and a blocking disk that locks the powered wheel in position between steps.
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.
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth operating of the worm gear combined with the use of cast iron and huge precision on component manufacturing and assembly. Regarding the 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 definitely reduced to a complete minimum.
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This typically proves to be a decisive advantage making the incorporation of the gearbox considerably simpler and more compact.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 apparatus house and is well suited for direct suspension for wheels, movable arms and other parts rather than having to build a separate suspension.
For larger equipment ratios,EP-Gear’s worm gearboxes provides a self-locking impact, which in many situations can be used as brake or as extra security. Likewise spindle gearboxes with a trapezoidal spindle are self-locking, making them ideal for an array of solutions.
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 are available for all sorts of gear-reducer. This make sure they are perform efficiently under stressed circumstances, vibrations or any type 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 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 noise amounts 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), supply the best gear reducer on the market.
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 exists like response to the demand 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 rest of technical feature are similar to the its analogous in the size 62.
In order to set up a gear reducer and also to make it work efficiently, the following 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 apparatus reducer had to be painted, the oil seals should 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.
It is wise to focus on this issue when the gear reducer output shaft is driven rather than being a driver. Bearing in mind that one of the top features of this worm-equipment reducer is the fact that cannot be axle-driven by the output shaft (irreversibility), it really is almost unattainable to meet total irreversibility conditions, because of external factors such as for example vibrations, etc. This is why, when the application requires total irreversibility, it really is advisable to make use of external brakes with enough power to avoid slipping.
It may be said that the circumstances under which irreversibility can occur are the following:
• Efficiency < 0,55 (find table of specialized features).
This sort of gear reducer is provided with a permanent lubrication, so it does not need any type of maintenance.
The lubrication of the gear reducer type is constant and comes as standard, with top quality refined oil which has 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.
