Planetary Speed Reducer Working Principle and Applications

How planetary reducer works?

Planetary reducer and gearbox are a kind of transmission mechanism. The speed converter of the gearbox is used to reduce the number of revolutions of the motor to the required number and obtain a large torque. We can learn more from the structure.

The main transmission structures of the planetary gearbox are planetary gear, sun gear, and ring gear. The ring gear is in close contact with the inner gearbox case. The sun gear, driven by external power, is in the center of the ring gear. Between the sun gear and the ring gear, there is a planetary gear set in which three gears are evenly built on the planetary gear, which relies on the support of the output shaft, ring gear, and sun gear to float between them. When the sun gear is operated by the input power, the planetary gear is driven and rotates around the center along the orbit of the ring gear. The rotation of the planetary gear drives the output shaft connected to the carrier to output power.

Planetary reducer application

Planetary reducer and gearbox have many advantages such as small size, lightweight, high load performance, long service life, high reliability, low noise, large output torque, wide speed ratio, high efficiency, etc. Also, Top Gear Transmissions' planetary reducer gearbox is designed for rectangular flanges, easy and convenient to install, suitable for AC/DC servo motors, stepper motors, hydraulic motors, etc.

Due to these advantages, planetary gearboxes are applied in lifting transportation, engineering machinery, The food industry, construction, environment, agriculture, woodworking machinery, industrial automation, mining industry, stone and marble industry, off-road vehicle, material handling, process industry

6 Types Of Industrial Gearboxes And Their Most Typical Uses

Image
Industrial gearboxes are enclosed systems that transmit mechanical energy to the output device. Gearboxes can convert energy into usable formats by modifying speed, torque and other properties. Gearboxes are used in a variety of devices for a variety of applications. These machines can slow down their rotation to increase torque and speed. The following describes the different types of industrial gearboxes and how they are commonly used. Helical gearbox The helical gearbox is a low power consumer and has a small size. This equipment is used for a wide range of industrial applications, but is typically used for heavy duty applications. Helical gearboxes are widely used in plastic, cement, rubber and other heavy industry environments. Coaxial helical inline The coaxial helical gearbox is ideal for heavy duty applications. The coaxial helical inline is known for its quality and efficiency. They are manufactured to high standard specifications to maximize load and transmission ratio. Beve

Leading Gearbox Manufacturers in India for Travelling Grate

Image
If you are a Travelling Grate Manufacturer and are looking for a reliable supplier of Gearboxes then you are at a right place. This blog will give you a clear insight of reliable manufacturer of gearboxes for travelling grate. Top Gear Transmissions the leading manufacturer of Industrial Gearboxes in India is supplying highly efficient and reliable gearboxes for travelling grate application from last two decades. With more than 20000+ gearboxes installed all gearboxes are running satisfactory.  Efficiency of travelling grate is very important, inefficient travelling grate boilers causes a considerable energy waste. According to statistics there are >500 000 industrial boilers, representing about one-third of the total nationwide coal consumption. Most of these industrial boilers are coal fired travelling grate. The thermal efficiency of many of these boilers is only 60–70% which leads to a remarkable waste in energy. Use of hydraulic drives or inefficient gearboxes is also one of t
