Worm Wheel Miniature Gearboxes
Our RW series miniature worm equipment box assembly may be little, but it’s hard enough to take care of demanding power transfer applications. Designed with machined aluminium housings and hardened metal input and result gears, they’ll deliver a long time of reliable performance.
Available in three standard output ratios and with two output shaft diameter options, it’s simple to find the EP correct miniature gearbox to your requirements. Each RW model worm gear package assembly provides proportionally substantial 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 – GEAR BOXES – on blue – smallto the speed decrease ratio. EP has a full line of gearboxes and acceleration reducers, and the parts needed to build them, in an array of regular ratios and shaft choices and also custom designs.
Helical, bevel, and miter equipment boxes provide options of rate reducers or swiftness increasers, and may be powered in either direction. All EP worm equipment speed reducers and right angle drives are manufactured for high performance in a large spectral range of applications. Typically worm gear boxes aren’t used as rate increasers. The instances are molded glass-filled materials making them extremely durable and resilient to corrosive environments. They are offered in a wide variety of ratios and are built with right hands or left hand worm gears. The output shafts may be stable or hollow, and load capability is unaffected by direction and rotation.
Worm gear acceleration reducers are made up of a screw (the worm) that drives a steering wheel (helical gear) or solitary enveloping wheel and are used 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 reaches right into a slot of the driven wheel advancing it by one step and a blocking disk 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 through the use of adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are really quiet. This is because of the very smooth operating of the worm gear combined with the usage of cast iron and large precision on element manufacturing and assembly. Regarding the our precision gearboxes, we consider extra care of any sound which can be interpreted as a murmur from the gear. So the general noise degree of our gearbox is definitely reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This typically proves to become a decisive advantage making the incorporation of the gearbox significantly simpler and smaller sized.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 quite firmly embedded in the apparatus house and is well suited for direct suspension for wheels, movable arms and other areas rather than having to create a separate suspension.
Self locking
For larger gear ratios,EP-Gear’s worm gearboxes provides a self-locking impact, which in many situations can be used as brake or as extra security. As well spindle gearboxes with a trapezoidal spindle happen to be self-locking, making them well suited for a wide selection of solutions.
Structural Features
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are made from GG-25 cast-iron, and are available for all kinds of gear-reducer. This make them perform effectively under stressed conditions, vibrations or any type of setback that can’t be avoided through the assembly
The worm-gear is made from 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 top quality, excellent functionality and low sound levels 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), supply the best 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 is born like answer to the demand of our costumers since, upon mounting better bearings in the output, bears higher 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.
Assembly Position
In order to setup a gear reducer and also to make it happen efficiently, the following instructions must be considered:
It must be fixed on a flat 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 oil seals must be covered to avoid them from drying and losing their seal.
The device work of the fittings set up in the output shafts need an ISO H7 or h6 margin for the hollow shaft.
Backdriving
It is smart to pay attention to this component when the gear reducer output shaft is driven rather than being a driver. Bearing in mind that one of the features of this worm-gear reducer may be the fact that can’t be axle-powered by the output shaft (irreversibility), it really is almost difficult to meet up total irreversibility conditions, due to external factors such as for example vibrations, etc. For this reason, 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 circumstances under which irreversibility can occur are as follows:
• Efficiency < 0,55 (observe table of specialized features).
Maintenance
This kind of gear reducer will get a permanent lubrication, so that it does not need any type of maintenance.
Lubrication
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 quality level CLP DIN 51517-3, FGZ level 12, AP GL-4, US 224, AGMA 250-04; for that reason its maintenance isn’t needed.
