Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be small, but it’s difficult enough to handle demanding power transfer applications. Designed with machined light weight aluminum housings and hardened steel input and result gears, they’ll deliver a long time of reliable performance.
Available in three standard result ratios and with two output shaft size options, it’s easy to find the EP right miniature gearbox for your needs. Each RW model worm gear container assembly provides proportionally large torque values (1.4 NM at 3,000 RPM) with suprisingly low backlash (maximum 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 type of gearboxes and rate reducers, and the components needed to build them, in a wide range of standard ratios and shaft options in addition to custom designs.
Helical, bevel, and miter gear boxes provide options of velocity reducers or quickness increasers, and may be driven in either direction. All EP worm gear speed reducers and correct angle drives are manufactured for powerful in a large spectral range of applications. Typically worm gear boxes are not used as acceleration increasers. The instances are molded glass-filled material making them extremely durable and resilient to corrosive environments. They are offered in a wide range of ratios and are built with right hand or left hands worm gears. The output shafts may be sturdy or hollow, and load capability is unaffected by direction and rotation.
Worm gear speed reducers are comprised of a good screw (the worm) that drives a wheel (helical gear) or solitary enveloping wheel and are found 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 steering wheel has a pin that reaches into a slot of the powered steering wheel advancing it by one step and a blocking disc that locks the driven wheel constantly in place between steps.
Compact design
Compact design is one of the key terms of the typical gearboxes of the BJ-Series. Further optimisation can be achieved by using adapted gearboxes or particular 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 substantial precision on component manufacturing and assembly. In connection with our precision gearboxes, we take extra care of any sound which can be interpreted as a murmur from the apparatus. Therefore the general noise degree of our gearbox is certainly reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to each other. This sometimes proves to be a decisive advantage producing the incorporation of the gearbox significantly simpler and more compact.The worm gearbox can be an angle gear. This is 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 gear house and is ideal for immediate 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 utilized as brake or as extra security. Likewise spindle gearboxes with a trapezoidal spindle will be self-locking, making them well suited 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 constructed with GG-25 cast-iron, and are available for all kinds of gear-reducer. This make sure they are perform efficiently under stressed conditions, vibrations or any type 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 manufactured from DIN (GZ-CuSn 12 Ni2) centricast bronze, melted on steel. Due to the mechanical work of these two parts having high quality, excellent efficiency and low noise levels have been achived.
The output shaft is hollow, although 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), supply 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 offers like reference size 63 and exists like answer to the ask for of our costumers since, after mounting better 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 setup a gear reducer and to make it happen efficiently, the next instructions must be taken into account:
It should be fixed on a set 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 needed to be painted, the essential oil seals must be covered to prevent 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 smart to pay attention to this issue when the gear reducer result shaft is driven rather than being a driver. Considering that one of the top features of this worm-gear reducer is the fact that cannot be axle-driven 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 make use of external brakes with enough power to avoid slipping.
It may be said that the circumstances under which irreversibility can happen are as follows:
• Efficiency < 0,55 (see table of technical features).
Maintenance
This sort of gear reducer is provided with a permanent lubrication, so that it will not need any kind of maintenance.
Lubrication
The lubrication of this gear reducer type is continuous and comes as standard, with top 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 is not needed.
