worm gear box assembly
EP has been creating and manufacturing reliable, high performance gearboxes for over twenty years. RW Series miniature right angle gearboxes offer high torque values with suprisingly low backlash in extremely compact frames. Three equipment ratios are available to meet the requirements of your unique application.

Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be little, but it’s hard enough to handle demanding electricity transfer applications. Constructed with machined light weight aluminum housings and hardened metal input and result gears, they’ll deliver a long time of reliable performance.
Available in three standard result ratios and with two output shaft diameter options, it’s simple to find the EP correct miniature gearbox for your needs. Each RW style worm gear container assembly provides proportionally high torque values (1.4 NM at 3,000 RPM) with suprisingly low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque based on application. Also swiftness is increased or reduced compared index G – GEAR BOXES – on blue – smallto the speed decrease ratio. EP has a full type of gearboxes and speed reducers, and the components needed to build them, in a wide variety of regular ratios and shaft options as well as custom designs.
Helical, bevel, and miter gear boxes offer the options of quickness reducers or swiftness increasers, and may be driven in either path. All EP worm gear 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 cases are molded glass-filled materials making them extremely tough and resilient to corrosive environments. They can be found in a wide selection of ratios and are equipped with right hands or left hands worm gears. The result shafts may be sturdy or hollow, and load capability is unaffected by direction and rotation.
Worm gear rate reducers are comprised of a good screw (the worm) that drives a wheel (helical gear) or single enveloping wheel and so are used in mechanical applications ranging from conveyors to exercise 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 gets to into a slot of the powered wheel advancing it by one stage and a blocking disc that locks the driven wheel in position between steps.
Compact design
Compact design is among the key phrases of the standard gearboxes of the BJ-Series. Further optimisation can be achieved through the use of adapted gearboxes or special 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 usage of cast iron and high precision on component manufacturing and assembly. Regarding the our accuracy gearboxes, we take extra treatment of any sound that can be interpreted as a murmur from the apparatus. So the general noise level of our gearbox can be reduced to a complete minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This generally 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 advantage for incorporation into constructions.
Solid bearings in solid housing
The output shaft of the BJ worm gearbox is very firmly embedded in the apparatus 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 gear ratios,EP-Gear’s worm gearboxes provides a self-locking effect, which in many situations can be used as brake or as extra protection. Likewise spindle gearboxes with a trapezoidal spindle are self-locking, making them perfect for an array of solutions.
Structural Features
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 types of gear-reducer. This make them perform effectively under stressed circumstances, vibrations or any kind of setback that can’t be avoided during the assembly
The worm-gear is constructed 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 performance and low sound levels have been achived.
The output shaft is hollow, though it is possible to adapt a good 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 provides like reference size 63 and exists like answer to the request of our costumers since, upon mounting better bearings in the result, bears higher 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 to make it happen efficiently, the next instructions must be considered:
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 had to be painted, the oil seals should be covered to avoid them from drying and losing their seal.
The machine 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 aspect when the gear reducer result shaft is driven instead of being a driver. Considering that among the top features of this worm-gear reducer may be the fact that cannot be axle-driven by the result shaft (irreversibility), it is almost impossible to meet up total irreversibility conditions, due to external elements such as vibrations, etc. For this reason, when the application needs total irreversibility, it is advisable to utilize external 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 (find table of specialized features). Maintenance This kind of gear reducer is provided with a permanent lubrication, so that it does not need any type of maintenance. Lubrication The lubrication of this gear reducer type is continuous and comes as standard, with high quality refined oil which includes antirust and antiwear products with Fe, Cu and alloy protectors that has quality level CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; for that reason its maintenance is not needed.
