worm gear box assembly

worm gear box assembly
EP has been developing and manufacturing reliable, high performance gearboxes for over 20 years. RW Series miniature right angle gearboxes offer high torque values with very low backlash in extremely compact frames. Three equipment ratios are available to meet up the necessities of your unique application.

Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly may be small, but it’s tough enough to handle demanding electric power transfer applications. Designed with machined aluminum housings and hardened metal input and result gears, they’ll deliver a long time of reliable performance.
Obtainable in three standard output ratios and with two output shaft size options, it’s simple to find the EP correct miniature gearbox for your needs. Each RW model worm gear package assembly provides proportionally huge 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 speed is increased or decreased in proportion index G – GEAR BOXES – on blue – smallto the speed decrease ratio. EP has a full type of gearboxes and speed reducers, and the components had a need to build them, in an array of standard ratios and shaft choices and also custom designs.
Helical, bevel, and miter gear boxes provide options of quickness reducers or velocity increasers, and could be driven in either direction. All EP worm equipment speed reducers and right angle drives are produced for powerful in a large spectrum of applications. Commonly worm gear boxes are not used as velocity increasers. The situations are molded glass-filled material making them extremely durable and tolerant to corrosive conditions. They can be found in a wide range of ratios and are built with right hand or left hands worm gears. The result shafts may be solid or hollow, and load capacity is unaffected by path and rotation.
Worm gear speed reducers are made up of a screw (the worm) that drives a wheel (helical gear) or solitary enveloping wheel and so 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 motion into intermittent rotary motion. The rotating drive steering wheel includes a pin that gets to right into a slot of the powered wheel advancing it by one step and a blocking disk that locks the driven wheel in position between steps.
Compact design
Compact design is one of the key phrases of the typical 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 extremely quiet. This is due to the very smooth running of the worm equipment combined with the use of cast iron and high precision on element manufacturing and assembly. Regarding the our precision gearboxes, we consider extra treatment of any sound which can be interpreted as a murmur from the gear. So the general noise degree of our gearbox is reduced to an absolute minimum.
Angle gearboxes
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This frequently proves to become a decisive advantage making the incorporation of the gearbox substantially simpler and more compact.The worm gearbox can be 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 parts rather than having to build a separate suspension.
Self locking
For larger equipment ratios,EP-Gear’s worm gearboxes provides a self-locking effect, which in many situations can be used as brake or as extra protection. As well spindle gearboxes with a trapezoidal spindle are self-locking, making them ideal 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 from GG-25 cast-iron, and so are available for all kinds of gear-reducer. This make sure they are perform effectively under stressed circumstances, vibrations or any type of setback that can’t be avoided through 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 the two parts having top quality, excellent performance and low noises amounts have been achived.
The output shaft is hollow, though it is possible 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 on the market.
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, after mounting better bearings in the result, bears better axial loads that its analogous one in the MF-62 series. The rest of technical characteristic are similar 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 next instructions must be considered:
It must be fixed on a set surface in order 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 needed to be painted, the oil seals must 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 pay attention to this aspect when the apparatus reducer output shaft is driven rather than being a driver. Bearing in mind that among the features of this worm-gear reducer may be the fact that can’t be axle-powered by the output shaft (irreversibility), it is almost impossible to meet total irreversibility conditions, due to external elements such as for example vibrations, etc. That is why, when the application needs total irreversibility, it is advisable to utilize external brakes with enough power to avoid slipping.
It could be said that the conditions under which irreversibility can occur are as follows:
• Efficiency < 0,55 (discover table of technical features).
Maintenance
This kind of gear reducer is provided with a permanent lubrication, so it does not need any kind of maintenance.
Lubrication
The lubrication of this gear reducer type is continuous and comes as standard, with high quality refined oil which has 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 isn’t needed.
