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

Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be small, but it’s tough enough to take care of demanding ability transfer applications. Designed with machined aluminium housings and hardened metal input and output gears, they’ll deliver many years of reliable performance.
Obtainable in three standard output ratios and with several output shaft size options, it’s easy to find the EP correct miniature gearbox to your requirements. Each RW model worm gear package assembly provides proportionally great torque values (1.4 NM at 3,000 RPM) with very low backlash (optimum 2° backlash).

Mechanical drives take supplied torque and could increase or reduce that torque predicated on application. Also quickness is increased or reduced in proportion index G – Equipment BOXES – on blue – smallto the speed reduction ratio. EP has a full type of gearboxes and speed reducers, and the parts had a need to build them, in an array of regular ratios and shaft options along with custom designs.
Helical, bevel, and miter gear boxes offer the options of speed reducers or swiftness increasers, and may be driven in either direction. All EP worm gear speed reducers and correct angle drives are produced for powerful in a large spectral range of applications. Typically worm gear boxes are not used as acceleration increasers. The situations are molded glass-filled material making them extremely durable and tolerant to corrosive conditions. They can be found in an array of ratios and are built with right hand or left hands worm gears. The output shafts may be solid 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 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 typically used to transform continuous rotary motion into intermittent rotary motion. The rotating drive steering wheel has a pin that gets to into a slot of the powered 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 special gearboxes.
Our worm gearboxes and actuators are extremely quiet. This is because of the very smooth running of the worm gear combined with the use of cast iron and substantial precision on element manufacturing and assembly. Regarding the our precision gearboxes, we take extra care of any sound that can be interpreted as a murmur from the apparatus. Therefore the general noise level of our gearbox is reduced to a complete minimum.
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This sometimes proves to be a decisive advantage producing the incorporation of the gearbox significantly 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 gear house and is well suited for direct suspension for wheels, movable arms and other areas rather than having to build a separate suspension.
For larger gear ratios,EP-Gear’s worm gearboxes provides a self-locking effect, which in many situations can be utilized 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 comprises 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 conditions, vibrations or any type of setback that cannot be avoided during 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 efficiency and low noise 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, high quality bearings, an EPOXY- impregnated finish ( 2 components), and grey-coloured SINGLE LAYER ENAMEL finish ( 2 components) ( RAL 7672), supply the best gear reducer available.
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 exists like answer to the demand of our costumers since, upon mounting higher bearings in the result, bears better axial loads that its analogous one in the MF-62 series. The others of technical characteristic are identical to the its analogous in the size 62.
In order to set up a gear reducer and to make it work efficiently, the following instructions must be considered:
It must be fixed on a set surface 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 had to be painted, the oil seals should be covered to prevent them from drying and losing their seal.
The device work of the fittings setup in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
It is wise to focus on this aspect when the gear reducer output shaft is driven rather than being a driver. Bearing in mind that one of the features of this worm-equipment reducer is the fact that can’t be axle-driven by the output shaft (irreversibility), it really is almost impossible to meet total irreversibility conditions, due to external elements such as vibrations, etc. This is why, when the application requires total irreversibility, it really is advisable to utilize exterior brakes with enough power to avoid slipping.
It may be said that the circumstances under which irreversibility can occur are as follows:
• Efficiency < 0,55 (see table of technical features). Maintenance This sort of gear reducer will get a permanent lubrication, so it does 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 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 is not needed.
