In a planetary gearbox, many teeth are involved at once, which allows high speed reduction to be achieved with fairly small gears and lower inertia reflected back again to the motor. Having multiple teeth talk about the load also allows planetary gears to transmit high degrees of torque. The combination of compact size, large speed decrease and high torque transmitting makes planetary gearboxes a favorite choice for space-constrained applications.
But planetary gearboxes do have some disadvantages. Their complexity in design and manufacturing tends to make them a more expensive solution than various other gearbox types. And precision manufacturing is really important for these gearboxes. If one planetary gear is put closer to the sun gear than the others, imbalances in the planetary gears can occur, leading to premature wear and failing. Also, the compact footprint of planetary gears makes high temperature dissipation more difficult, so applications that run at very high speed or encounter continuous operation may require cooling.
When using a “standard” (i.e. inline) planetary gearbox, the motor and the powered equipment must be inline with each other, although manufacturers offer right-angle designs that integrate other gear sets (often bevel gears with helical the teeth) to provide an offset between the input and output.

PG planetary gear models are divided into 21 basic organizations depending on the different torques that should be transmitted to the output shaft, which can change from 0,05 to at least one 1.280 kNm. Actually, the product modular construction permits the coupling of bevel gears, worm gears, hydraulic brakes and a variety of input shafts to the 
planetary systems, in addition to providing for a wide choice of coupling flanges for hydraulic or electric motors. Another advantage provided by the modular structure technique of the planetary gear units may be the possibility to mount a series of levels of different sizes to be able to obtain a vast range of decrease ratios. The merchandise range provides decrease ratios from 3:1 to 7:1 about the same stage unit up to 10.000:1 and more on a 5 stage unit. The wide selection of result shafts and flanges simplifies the reduction unit mounting operation on industrial machinery or plants.

In an epicyclic or planetary gear train, several spur gears distributed evenly around the circumference operate between a gear with internal teeth and a gear with external teeth on a concentric orbit. The circulation of the spur gear occurs in analogy to the orbiting of the planets in the solar system. This is one way planetary gears acquired their name.
The elements of a planetary gear train could be divided into four main constituents.
The housing with integrated internal teeth is actually a ring gear. In the majority of cases the casing is fixed. The generating sun pinion is in the center of the ring equipment, and is coaxially arranged with regards to the output. The sun pinion is usually mounted on a clamping system in order to offer the mechanical connection to the engine shaft. During operation, the planetary gears, which are mounted on a planetary carrier, roll between the sun pinion and the band equipment. The planetary carrier also represents the result shaft of the gearbox.
The sole reason for the planetary gears is to transfer the mandatory torque. The number of teeth does not have any effect on the transmitting ratio of the gearbox. The number of planets may also vary. As the number of planetary gears improves, the distribution of the strain increases and then the torque which can be transmitted. Increasing the amount of tooth engagements also reduces the rolling power. Since only area of the total result has to be transmitted as rolling power, a planetary equipment is incredibly efficient. The advantage of a planetary gear compared to an individual spur gear is based on this load distribution. It is therefore possible to transmit high torques wit
h high efficiency with a concise design using planetary gears.
Provided that the ring gear includes a constant size, different ratios could be realized by different the amount of teeth of the sun gear and the amount of the teeth of the planetary gears. Small the sun gear, the higher the ratio. Technically, a meaningful ratio range for a planetary stage is usually approx. 3:1 to 10:1, because the planetary gears and the sun gear are extremely small above and below these ratios. Higher ratios can be obtained by connecting a number of planetary levels in series in the same ring gear. In this case, we speak of multi-stage gearboxes.
With planetary gearboxes the speeds and torques can be overlaid by having a band gear that’s not fixed but is driven in any direction of rotation. Additionally it is possible to fix the drive shaft in order to grab the torque via the ring gear. Planetary gearboxes have grown to be extremely important in lots of regions of mechanical engineering.
They have become particularly more developed in areas where high output levels and fast speeds should be transmitted with favorable mass inertia ratio adaptation. High transmitting ratios can also easily be performed with planetary gearboxes. Because of the positive properties and compact design, the gearboxes possess many potential uses in commercial applications.
The benefits of planetary gearboxes:
Coaxial arrangement of input shaft and output shaft
Load distribution to several planetary gears
High efficiency because of low rolling power
Almost unlimited transmission ratio options due to combination of several planet stages

Ever-Power Transmission planetary gearboxes are applied to different component of wind energy plant: the rotor and the nacelle. Our slewing planetary gear products from the yaw and pitch range are normally used to regulate blade pitch. The nacelle near the top of the tower is connected to the rotor and homes the gearbox, the power generator, the yaw program, and the control program. To ensure that the rotor axis is constantly aligned with the wind direction for maximum energy result, large wind turbines are equipped with a yaw system that allows the nacelle to change its position based on the direction and power of the wind. Nacelle rotation is definitely managed by a yaw system, planetary gear unit with electric brake electric motor, which is one of Ever-Power s most popular products. Each wind mill must have between two and six equipment units, based on the size, and the electric motor can be electrical or hydraulic. Two or three-stage gear units, combined with a worm gearbox on the input part, or four or five-stage gear units from the yaw and pitch drive series are normally used. Output pinions could be integrated or inserted. Ever-Power is definitely proud of its quality assurance policy, including the Type Acceptance Certificate from DNV.
