Operating Theory
Single reduction gear is a driving bevel gear (commonly recognized as angular equipment) and a basin angle equipment pair. The driving bevel equipment is linked with the transmission shaft, rotates clockwise, sticks to its right aspect from the bevel equipment, and rotates downward at the meshing point, which is consistent with the forward course of the wheel. Due to the modest diameter of the driving bevel equipment and the big diameter of the bevel gear, the purpose of deceleration is reached.
The double reduction has an extra intermediate changeover gear.The left aspect of the driving bevel gear is meshed with the bevel equipment of the intermediate equipment. The bevel gear is coaxial with a spur gear with modest diameter, and the spur equipment is meshed with the pushed equipment. In this way, the intermediate gear rotates backward and the driven equipment rotates ahead. There is a two-stage deceleration process in the middle.
Owing to the improve of axle volume, double reduction was primarily utilized in vehicles with lower engine electricity in the past, primarily in building equipment with reduced pace and higher torque.
In the double reduction ultimate generate, if the second-phase deceleration is carried out close to the wheel, it actually constitutes an independent part at the 2 wheels, it is named wheel reducer. The edge of this is that the torque transmitted by the 50 percent shaft can be decreased, which is conducive to reducing the dimension and top quality of the half shaft. The wheel reducer can be planetary equipment sort or composed of a pair of cylindrical gear pairs. When the cylindrical gear pair is employed for wheel side deceleration, the up-down placement relationship in between the wheel axis and the 50 % shaft can be changed by changing the mutual place of the 2 gears. This kind of axle is referred to as portal axle, which is often employed for cars with unique needs for the large and lower situation of the axle.
In accordance to the number of the major reducer transmission ratio, it can be divided into single-velocity and double-speed.
Domestic vehicles essentially undertake one pace major reducer with fixed transmission ratio. On the double reduction closing generate, there are 2 transmission ratios for variety, and this principal reducer truly acts as an auxiliary transmission.

The Difference Between Planetary Gears and Spur Gears
A spur gear is a type of mechanical drive that turns an external shaft. The angular velocity is proportional to the rpm and can be easily calculated from the gear ratio. However, to properly calculate angular velocity, it is necessary to know the number of teeth. Fortunately, there are several different types of spur gears. Here’s an overview of their main features. This article also discusses planetary gears, which are smaller, more robust, and more power-dense.
Planetary gears are a type of spur gear
One of the most significant differences between planetary gears and spurgears is the way that the two share the load. Planetary gears are much more efficient than spurgears, enabling high torque transfer in a small space. This is because planetary gears have multiple teeth instead of just one. They are also suitable for intermittent and constant operation. This article will cover some of the main benefits of planetary gears and their differences from spurgears.
While spur gears are more simple than planetary gears, they do have some key differences. In addition to being more basic, they do not require any special cuts or angles. Moreover, the tooth shape of spur gears is much more complex than those of planetary gears. The design determines where the teeth make contact and how much power is available. However, a planetary gear system will be more efficient if the teeth are lubricated internally.
In a planetary gear, there are three shafts: a sun gear, a planet carrier, and an external ring gear. A planetary gear is designed to allow the motion of one shaft to be arrested, while the other two work simultaneously. In addition to two-shaft operation, planetary gears can also be used in three-shaft operations, which are called temporary three-shaft operations. Temporary three-shaft operations are possible through frictional coupling.
Among the many benefits of planetary gears is their adaptability. As the load is shared between several planet gears, it is easier to switch gear ratios, so you do not need to purchase a new gearbox for every new application. Another major benefit of planetary gears is that they are highly resistant to high shock loads and demanding conditions. This means that they are used in many industries.
They are more robust
An epicyclic gear train is a type of transmission that uses concentric axes for input and output. This type of transmission is often used in vehicles with automatic transmissions, such as a Lamborghini Gallardo. It is also used in hybrid cars. These types of transmissions are also more robust than conventional planetary gears. However, they require more assembly time than a conventional parallel shaft gear.
An epicyclic gearing system has three basic components: an input, an output, and a carrier. The number of teeth in each gear determines the ratio of input rotation to output rotation. In some cases, an epicyclic gear system can be made with two planets. A third planet, known as the carrier, meshes with the second planet and the sun gear to provide reversibility. A ring gear is made of several components, and a planetary gear may contain many gears.
An epicyclic gear train can be built so that the planet gear rolls inside the pitch circle of an outer fixed gear ring, or “annular gear.” In such a case, the curve of the planet’s pitch circle is called a hypocycloid. When epicycle gear trains are used in combination with a sun gear, the planetary gear train is made up of both types. The sun gear is usually fixed, while the ring gear is driven.
Planetary gearing, also known as epicyclic gear, is more durable than other types of transmissions. Because planets are evenly distributed around the sun, they have an even distribution of gears. Because they are more robust, they can handle higher torques, reductions, and overhung loads. They are also more energy-dense and robust. In addition, planetary gearing is often able to be converted to various ratios.
They are more power dense
The planet gear and ring gear of a compound planetary transmission are epicyclic stages. One part of the planet gear meshes with the sun gear, while the other part of the gear drives the ring gear. Coast tooth flanks are used only when the gear drive works in reversed load direction. Asymmetry factor optimization equalizes the contact stress safety factors of a planetary gear. The permissible contact stress, sHPd, and the maximum operating contact stress (sHPc) are equalized by asymmetry factor optimization.
In addition, epicyclic gears are generally smaller and require fewer space than helical ones. They are commonly used as differential gears in speed frames and in looms, where they act as a Roper positive let off. They differ in the amount of overdrive and undergearing ratio they possess. The overdrive ratio varies from fifteen percent to forty percent. In contrast, the undergearing ratio ranges from 0.87:1 to 69%.
The TV7-117S turboprop engine gearbox is the first known application of epicyclic gears with asymmetric teeth. This gearbox was developed by the CZPT Corporation for the Ilyushin Il-114 turboprop plane. The TV7-117S’s gearbox arrangement consists of a first planetary-differential stage with three planet gears and a second solar-type coaxial stage with five planet gears. This arrangement gives epicyclic gears the highest power density.
Planetary gearing is more robust and power-dense than other types of gearing. They can withstand higher torques, reductions, and overhung loads. Their unique self-aligning properties also make them highly versatile in rugged applications. It is also more compact and lightweight. In addition to this, epicyclic gears are easier to manufacture than planetary gears. And as a bonus, they are much less expensive.
They are smaller
Epicyclic gears are small mechanical devices that have a central “sun” gear and one or more outer intermediate gears. These gears are held in a carrier or ring gear and have multiple mesh considerations. The system can be sized and speeded by dividing the required ratio by the number of teeth per gear. This process is known as gearing and is used in many types of gearing systems.
Planetary gears are also known as epicyclic gearing. They have input and output shafts that are coaxially arranged. Each planet contains a gear wheel that meshes with the sun gear. These gears are small and easy to manufacture. Another advantage of epicyclic gears is their robust design. They are easily converted into different ratios. They are also highly efficient. In addition, planetary gear trains can be designed to operate in multiple directions.
Another advantage of epicyclic gearing is their reduced size. They are often used for small-scale applications. The lower cost is associated with the reduced manufacturing time. Epicyclic gears should not be made on N/C milling machines. The epicyclic carrier should be cast and tooled on a single-purpose machine, which has several cutters cutting through material. The epicyclic carrier is smaller than the epicyclic gear.
Epicyclic gearing systems consist of three basic components: an input, an output, and a stationary component. The number of teeth in each gear determines the ratio of input rotation to output rotation. Typically, these gear sets are made of three separate pieces: the input gear, the output gear, and the stationary component. Depending on the size of the input and output gear, the ratio between the two components is greater than half.
They have higher gear ratios
The differences between epicyclic gears and regular, non-epicyclic gears are significant for many different applications. In particular, epicyclic gears have higher gear ratios. The reason behind this is that epicyclic gears require multiple mesh considerations. The epicyclic gears are designed to calculate the number of load application cycles per unit time. The sun gear, for example, is +1300 RPM. The planet gear, on the other hand, is +1700 RPM. The ring gear is also +1400 RPM, as determined by the number of teeth in each gear.
Torque is the twisting force of a gear, and the bigger the gear, the higher the torque. However, since the torque is also proportional to the size of the gear, bigger radii result in lower torque. In addition, smaller radii do not move cars faster, so the higher gear ratios do not move at highway speeds. The tradeoff between speed and torque is the gear ratio.
Planetary gears use multiple mechanisms to increase the gear ratio. Those using epicyclic gears have multiple gear sets, including a sun, a ring, and two planets. Moreover, the planetary gears are based on helical, bevel, and spur gears. In general, the higher gear ratios of epicyclic gears are superior to those of planetary gears.
Another example of planetary gears is the compound planet. This gear design has two different-sized gears on either end of a common casting. The large end engages the sun while the smaller end engages the annulus. The compound planets are sometimes necessary to achieve smaller steps in gear ratio. As with any gear, the correct alignment of planet pins is essential for proper operation. If the planets are not aligned properly, it may result in rough running or premature breakdown.
