worm gear box assembly
EP has been creating and manufacturing reliable, powerful gearboxes for over 20 years. RW Series miniature correct angle gearboxes provide high torque values with very low backlash in incredibly compact frames. Three gear ratios happen to be available to meet up the needs of your specific application.

Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly could be little, but it’s challenging enough to handle demanding power transfer applications. Constructed with machined aluminum housings and hardened metal input and output gears, they’ll deliver a long time of reliable performance.
Available in three standard output ratios and with several output shaft size options, it’s easy to find the EP correct miniature gearbox for your needs. Each RW style worm gear box assembly provides proportionally huge 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 velocity is increased or reduced in proportion index G – GEAR BOXES – on blue – smallto the speed reduction ratio. EP has a full line of gearboxes and velocity reducers, and the elements needed to build them, in an array of regular ratios and shaft options and also custom designs.
Helical, bevel, and miter equipment boxes offer the options of rate reducers or acceleration increasers, and could be driven in either direction. All EP worm equipment 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 rate increasers. The situations are molded glass-filled material making them extremely tough and resistant to corrosive environments. They are offered in an array of ratios and are equipped with right hands or left hand worm gears. The result shafts may be stable or hollow, and load capability is unaffected by path and rotation.
Worm gear velocity reducers are made up of a good screw (the worm) that drives a steering wheel (helical gear) or one enveloping wheel and are used in mechanical applications which range from conveyors to physical exercise devices to robots.
Geneva mechanisms and assemblies are typically used to transform continuous rotary movement into intermittent rotary movement. The rotating drive wheel includes a pin that gets to 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
Compact design is among the key terms of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or unique gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth operating of the worm equipment combined with the use of cast iron and excessive precision on component manufacturing and assembly. Regarding the our accuracy gearboxes, we take extra treatment of any sound which 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 one another. This frequently proves to become a decisive advantage making the incorporation of the gearbox significantly simpler and more compact.The worm gearbox can be 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 very firmly embedded in the apparatus house and is perfect for direct suspension for wheels, movable arms and other areas rather than needing to build a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes will provide a self-locking impact, which in many circumstances can be used as brake or as extra security. Also spindle gearboxes with a trapezoidal spindle happen to be self-locking, making them ideal for a wide selection 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 sorts of gear-reducer. This make them perform efficiently under stressed circumstances, vibrations or any type of setback that can’t be avoided through the assembly
The worm-gear is constructed 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 efficiency and low sound amounts have been achived.
The output shaft is hollow, though it can be done 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), provide the best gear reducer available.
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 response to the demand of our costumers since, after mounting greater bearings in the result, 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 set up a gear reducer and also to make it happen efficiently, the following instructions must be considered:
It should be fixed on a set surface to avoid either vibrations or perhaps 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 had to be painted, the essential oil seals must be covered to avoid them from drying and losing their seal.
The machine 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 point when the gear reducer output shaft is driven rather than being a driver. Considering that among the features of this worm-gear reducer may be the fact that cannot be axle-powered by the result 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 really is advisable to make use of exterior brakes with enough capacity to avoid slipping.
It could be said that the conditions under which irreversibility can happen are the following:
• Efficiency < 0,55 (observe 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 constant and comes as standard, with high 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.
