worm gear box assembly

worm gear box assembly
EP has been designing and manufacturing reliable, powerful gearboxes for over 20 years. RW Series miniature correct angle gearboxes offer high torque ideals with suprisingly low backlash in incredibly compact frames. Three equipment ratios are available to meet up the desires of your specific application.

Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be tiny, but it’s difficult enough to handle demanding ability transfer applications. Constructed with machined aluminium 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 simple to find the EP correct miniature gearbox to your requirements. Each RW version worm gear box assembly provides proportionally great torque values (1.4 NM at 3,000 RPM) with very low backlash (maximum 2° backlash).

Mechanical drives take supplied torque and may increase or reduce that torque predicated on application. Also speed is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed decrease ratio. EP includes a full type of gearboxes and quickness reducers, and the components had a need to build them, in a wide variety of regular ratios and shaft options along with custom designs.
Helical, bevel, and miter equipment boxes provide options of quickness reducers or quickness increasers, and could be driven in either path. All EP worm gear speed reducers and right angle drives are produced for powerful in a large spectrum of applications. Commonly worm gear boxes aren’t used as speed increasers. The instances are molded glass-filled materials making them extremely rugged and resilient to corrosive environments. They are offered in an array of ratios and are equipped with right hands or left hands worm gears. The result shafts may be sound or hollow, and load capability is unaffected by direction and rotation.
Worm gear swiftness reducers are made up 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 typically used to transform continuous rotary motion into intermittent rotary movement. The rotating drive wheel includes 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 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 by using adapted gearboxes or special gearboxes.
Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth working of the worm equipment combined with the use of cast iron and excessive 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 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 be a decisive advantage making the incorporation of the gearbox substantially simpler and more compact.The worm gearbox is an angle gear. This is often an edge 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 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 effect, which in many situations can be used as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle will be self-locking, making them ideal for a wide variety 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 so are available for all kinds of gear-reducer. This make them perform effectively under stressed circumstances, vibrations or any type of setback that cannot be avoided during 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 these two parts having top quality, excellent functionality and low noises levels have been achived.
The output shaft is hollow, although it is possible to adapt a solid 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), provide the most competitive gear reducer out there.
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 has like reference size 63 and is born like answer to the request of our costumers since, upon mounting greater bearings in the result, bears greater axial loads that its analogous one in the MF-62 series. The others of technical feature are identical to the its analogous in the size 62.
Assembly Position
In order to set up a gear reducer and also to make it work efficiently, the following 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 recommended to insert compensating couplings, connectors, torque limiters etc…
If the apparatus reducer needed to be painted, the oil seals should 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 aspect when the gear reducer result shaft is driven rather than being a driver. Considering that among the top features of this worm-equipment reducer may be the fact that cannot be axle-driven by the output shaft (irreversibility), it really is almost unattainable to meet total irreversibility conditions, because of external factors such as for example vibrations, etc. This is why, when the application needs total irreversibility, it really 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 occur are the following:
• Efficiency < 0,55 (discover table of technical features).
Maintenance
This kind of gear reducer is provided with a permanent lubrication, so it will not need any kind of maintenance.
Lubrication
The lubrication of the gear reducer type is continuous and comes as standard, with top quality refined oil which includes 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.
