In the field of industrial machinery, planetary gear reducer is a common transmission device. It has the characteristics of high efficiency, high rigidity and high precision, and is widely used in various mechanical systems.This article will introduce the composition of the planetary gear reducer in detail so that readers can better understand and understand this important transmission device.
Planetary gear reducer mainly consists of the following parts:
1. Sun gear
The sun gear is one of the core components of the planetary gear reducer. It has an evenly distributed number and shape of teeth and meshes with the planet gear and the internal ring gear.The sun gear is usually made of materials with high strength and wear resistance, such as carbon steel, alloy steel, etc.
2. Planetary gear
The planetary gear is an important part of the planetary gear reducer. It has multiple planetary gears, which are connected together through a cage to form an integrated rotation.The planetary gear is small in size and is usually finely machined from high-quality alloy steel. It has a high load-bearing capacity and a long service life.
3. Internal ring gear
The internal ring gear is another important component of the planetary gear reducer. It meshes with the sun gear and the planet gear to form the transmission circuit of the reducer.The internal ring gear is usually made of materials with high strength and wear resistance, such as carbon steel, alloy steel, etc.
4. Cage
The cage is an important component in the planetary gear reducer used to maintain the relative position of the planetary gears.It is usually made of lightweight, high-strength materials, such as aluminum alloy, stainless steel, etc., to ensure that resonance and friction will not occur during high-speed operation.
5. Cabinet
The box is the basic component of the planetary gear reducer. It is used to support and fix all gears, bearings and other transmission components.The box body is usually made of materials such as high-strength steel or cast iron to ensure that it will not be deformed or damaged when bearing large loads.
6. Input shaft and output shaft
The input shaft is the input end of the planetary gear reducer, which is connected to the prime mover; the output shaft is the output end of the planetary gear reducer, which is connected to the working machine.The input shaft and output shaft are usually made of materials with high strength and wear resistance, such as carbon steel, alloy steel, etc.
To sum up, the planetary gear reducer is mainly composed of sun gear, planet gear, internal ring gear, cage, box, input shaft and output shaft.Each of these components has different functions and characteristics, but working together allows the planetary gear reducer to achieve high efficiency, high rigidity and high precision transmission.By understanding the composition of the planetary gear reducer, readers can better understand and understand this important transmission device, providing reference and guidance for practical applications.
Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
How to provide goods?
Usually we will ship the goods to the sea. The factory is only 460 kilometers away from the port. It is very convenient and convenient to transport the goods to any other country. Of course, if your cargo is very urgent, Ningbo Airport and Shanghai Airport are also nearby.
What is the payment term?
When we provide you with a quotation, we will negotiate with you: EXW, FCA, FOB, CIF, CRF, DAP Etc. For mass production, you need to pay 30% of the deposit before production and 70% of the balance before shipment. Our most common way is T/T.
How to ensure the quality of your products?
First, we will check after each process. For finished products, according to customer requirements and international standards.
How many employees does your company have? What is the relationship between technicians?
We now have more than 180 employees, including 36 engineers and 28 QCs.
What is the ability of your company?
We have a number of production lines with a monthly production capacity of 1,600 units and an annual production capacity of 20,000 units.
