Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be tiny, but it’s challenging enough to take care of demanding electricity transfer applications. Constructed with machined aluminum housings and hardened steel input and output gears, they’ll deliver many years of reliable performance.
Obtainable in three standard output ratios and with several output shaft diameter options, it’s simple to find the EP right miniature gearbox for your needs. Each RW unit worm gear box assembly provides proportionally great torque values (1.4 NM at 3,000 RPM) with suprisingly low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque predicated on application. Also rate is increased or reduced in proportion index G – GEAR BOXES – on blue – smallto the speed decrease ratio. EP has a full line of gearboxes and speed reducers, and the parts needed to build them, in an array of standard ratios and shaft choices along with custom designs.
Helical, bevel, and miter equipment boxes offer the options of quickness reducers or quickness increasers, and could be driven in either direction. All EP worm gear speed reducers and correct angle drives are produced for high performance in a large spectrum of applications. Typically worm gear boxes aren’t used as speed increasers. The instances are molded glass-filled materials making them extremely rugged and resistant 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 sturdy or hollow, and load capacity is unaffected by direction and rotation.
Worm gear velocity reducers are comprised of a good screw (the worm) that drives a steering wheel (helical gear) or one enveloping wheel and so are found in mechanical applications ranging from conveyors to exercise 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 gets to right into a slot of the driven wheel advancing it by one stage and a blocking disc that locks the driven wheel constantly in place between steps.
Compact design is one of the key words of the typical gearboxes of the BJ-Series. Further optimisation can be achieved through the use of adapted gearboxes or unique gearboxes.
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth operating of the worm equipment combined with the utilization of cast iron and huge precision on element manufacturing and assembly. In connection with our accuracy gearboxes, we take extra care of any sound which can be interpreted as a murmur from the gear. So the general noise degree of our gearbox is reduced to a complete minimum.
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This typically proves to be a decisive advantage making the incorporation of the gearbox considerably simpler and smaller sized.The worm gearbox is 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 quite firmly embedded in the apparatus house and is well suited for immediate suspension for wheels, movable arms and other parts rather than having to create a separate suspension.
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. As well spindle gearboxes with a trapezoidal spindle happen to be self-locking, making them ideal for a wide variety 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 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 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 noises levels have been achived.
The output shaft is hollow, though it is possible 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.
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 request of our costumers since, upon mounting greater bearings in the output, bears better axial loads that its analogous one in the MF-62 series. The rest of technical characteristic are identical to the its analogous in the size 62.
In order to setup a gear reducer and also to make it happen efficiently, the following instructions must be taken into account:
It must be fixed on a flat surface in order to avoid either vibrations or perhaps 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 prevent 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.
It is wise to focus on this point when the gear reducer result shaft is driven instead of being a driver. Considering that one of the top features of this worm-equipment reducer is the fact that cannot be axle-powered by the output shaft (irreversibility), it is almost unattainable to meet total irreversibility conditions, due to external factors such as vibrations, etc. That is why, when the application needs total irreversibility, it is advisable to utilize exterior 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 (observe table of technical features).
This kind of gear reducer will get a permanent lubrication, so it does not need any type of maintenance.
The lubrication of this 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 which has level of quality CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; for that reason its maintenance isn’t needed.
