Worm Wheel Miniature Gearboxes
Our RW series miniature worm gear box assembly could be small, but it’s hard enough to take care of demanding electricity 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.
Obtainable in three standard result ratios and with several output shaft diameter options, it’s simple to find the EP right miniature gearbox for your needs. Each RW version worm gear container assembly provides proportionally excessive 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 based on application. Also velocity is increased or reduced compared index G – Equipment BOXES – on blue – smallto the speed decrease ratio. EP has a full line of gearboxes and acceleration reducers, and the components needed to build them, in a wide variety of regular ratios and shaft options and also custom designs.
Helical, bevel, and miter gear boxes provide options of rate reducers or swiftness increasers, and could be driven in either path. All EP worm gear speed reducers and right angle drives are manufactured for powerful in a large spectrum of applications. Typically worm gear boxes are not used as acceleration increasers. The instances are molded glass-filled materials making them extremely durable and resilient to corrosive conditions. They can be found in an array of ratios and are equipped with right hand or left hands worm gears. The result shafts may be stable or hollow, and load capacity is unaffected by direction and rotation.
Worm gear swiftness reducers are made up of a screw (the worm) that drives a steering wheel (helical gear) or one enveloping wheel and are found in mechanical applications ranging from conveyors to workout devices to robots.
Geneva mechanisms and assemblies are usually used to transform continuous rotary movement into intermittent rotary movement. The rotating drive wheel has a pin that reaches into a slot of the driven wheel advancing it by one stage and a blocking disk that locks the powered wheel constantly in place between steps.
Compact design is among the key words of the standard gearboxes of the BJ-Series. Further optimisation may be accomplished by using adapted gearboxes or unique gearboxes.
Our worm gearboxes and actuators are really quiet. This is due to the very smooth operating of the worm equipment combined with the use of cast iron and substantial precision on element manufacturing and assembly. In connection with our precision gearboxes, we consider extra treatment of any sound that can be interpreted as a murmur from the apparatus. So the general noise degree of our gearbox is reduced to an absolute minimum.
On the worm gearbox the input shaft and output shaft are perpendicular to one another. This generally proves to become a decisive advantage producing the incorporation of the gearbox significantly simpler and smaller sized.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 perfect for immediate suspension for wheels, movable arms and other areas rather than needing to build a separate suspension.
For larger equipment ratios,EP-Gear’s worm gearboxes will provide a self-locking effect, which in many situations can be utilized as brake or as extra protection. Also spindle gearboxes with a trapezoidal spindle will be self-locking, making them ideal for a wide selection of solutions.
The worm-gear reducer comprises of three main parts: housing, worm-gear and wheel.
The carcasses are constructed with GG-25 cast-iron, and so are available for all types of gear-reducer. This make them perform effectively under stressed circumstances, vibrations or any kind 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. Because of the mechanical work of the two parts having high quality, excellent efficiency and low noise levels have been achived.
The output shaft is hollow, though it can be done 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 out there.
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 request of our costumers since, upon mounting higher bearings in the result, bears higher 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.
In order to create a gear reducer and also to make it happen efficiently, the next 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 gear reducer had to be painted, the essential oil seals should be covered to prevent them from drying and losing their seal.
The machine work of the fittings setup in the output shafts require an ISO H7 or h6 margin for the hollow shaft.
It is smart to pay attention to this aspect when the gear reducer output shaft is driven rather than being a driver. Considering that one of the features of this worm-equipment reducer is the fact that can’t be axle-driven by the result shaft (irreversibility), it really is almost unattainable to meet total irreversibility conditions, because of external elements such as for example vibrations, etc. That is why, when the application requires total irreversibility, it really is advisable to make use of exterior brakes with enough capacity to avoid slipping.
It could be said that the conditions under which irreversibility can occur are as follows:
• Efficiency < 0,55 (see table of specialized features).
This kind of gear reducer is provided with a permanent lubrication, so it does not need any type of maintenance.
The lubrication of the gear reducer type is constant and comes as standard, with top quality refined oil which includes 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; because of this its maintenance isn’t needed.
