Typical application scenarios of planetary gear reducers: crusher- Shanghai SGR Heavy Industry Machinery Co., Ltd.

Do you know that one of the typical application scenarios of planetary gear reducer is crusher?

Crusher is a commonly used industrial equipment, mainly used to crush and break block, granular or powdery materials. In mines and quarries, buildings and construction sites, metallurgical industry, chemical industry and other industries, crushers are inevitably used to break raw materials or waste for subsequent processing or recycling.

For SGR, one of the gear box manufacturers in China, announced that the application of planetary gear reducer in crusher is mainly used for torque transmission and speed reduction. It converts high-speed input power into low-speed and high-torque output power, which can effectively meet the crushing needs of crusher for different materials.

So what are the mechanical parameters of SGR planetary gear reducer? And how does the SGR planetary gear reducer work in a crusher?

(1) The mechanical parameters of SGR planetary gear reducer

Design features	Modular design, serialized specifications, and specialized production
Input characteristics	The input end has a round hole, a spline hole, a round shaft, an internal or external spline shaft, an additional flange, a brake, etc., which is suitable for hydraulic motors or electromagnetic motors, etc.;
Output characteristics	Output end types include round shaft, hollow shaft, hollow shaft with shrink disk, internal or external spline shaft, additional connecting plate, gear, flange, etc.
Others	There are many accessories, such as cooling and lubrication device, check valve, etc., which users can choose according to their needs.

(2) How does the SGR planetary gear reducer work in a crusher?

The SGR planetary gear reducer takes this input power and passes it through a system of gears: the sun gear, planet gears, and ring gear.

Sun gear is the central gear that receives input from the motor,and planet gears orbit around the sun gear and are meshed with it. they also mesh with the ring gear. The ring gear is the outer gear that interacts with the planet gears and transmits the output to the crusher mechanism.

SGR planetary gear reducer has the following four advantages on crushers.

The planetary gear reducer manufactured by the custom gearbox manufacturer SGR reduces the power loss of the transmission system through gear transmission, improves the transmission efficiency, and enables the crusher to convert the input power more effectively.

SGR planetary gear reducer has the characteristics of high torque output, which can meet the crusher's demand for high torque and improve the crusher's working capacity and crushing efficiency.

SGR planetary gear reducer has compact structure, smooth transmission and good operation stability. It can reduce the vibration and noise of the crusher and improve the working stability and reliability of the crusher.

SGR planetary gear reducer is made of wear-resistant materials, has high durability and reliability, can adapt to the requirements of the crusher working environment, and reduce the frequency of repair and replacement, reducing the cost of use and maintenance.

(3) Advantages of SGR planetary gear reducers

The SGR planetary gear reducers are based on the principle of power distribution and collection, and use internal and external meshing planetary gears for transmission. They have high power density and strong load-bearing capacity; they have various power forms, and generally use variable frequency speed regulating motors. The gears are made of high-strength alloy steel after quenching and grinding, with high strength, good wear resistance and long service life; the reducer ductile iron housing has small impact deformation resistance and high strength.

The custom gearbox manufacturer SGR r provides a full range of planetary gear reducers for crushers and shredders in multiple specifications. The reducer ratio is 5-150, and the torque ranges from 7000 Nm to 100000 Nm. We produce in batches and deliver quickly.

In summary, the planetary gear reducers of SGR used in the crusher can effectively improve the performance and efficiency of the entire crusher system with its unique four advantages.

The gear box manufacturer SGR, which has been deeply involved in the mechanical transmission industry for more than 10 years, has formed a research and development team composed of doctoral students and senior engineers, and has always focused on the research and development and production of planetary gear reducers, providing more specialized, more refined and newer planetary reducer products. It is foreseeable that in the future, SGR's continuously optimized and innovative planetary gear reducer products will surely play a greater role in the crusher industry. (Author: SGR, Angie Zhang)
