Common terms in reducer industry

The terms of the reducer industry are very important and very useful for you to purchase the reducer. Let's take a look with Xiaobian. I hope the study of these terms can help you.

Reduction ratio:

The output speed is higher than the input speed (the inner ring gear is fixed and the sun gear is active)

Series:

For the number of sets of planetary gears, because one set of planetary gears can not meet the requirements of large transmission ratio, sometimes two or three sets are required to meet the requirements of large transmission ratio. Due to the increase of the number of planetary gears, the length of the two-stage or three-stage reducer will increase and the efficiency will decrease.

Rated input speed:

When the driving speed and ambient temperature of the reducer are high, please reduce the input speed, which will help to improve the service life of the reducer.

Output speed:

The output speed is calculated from the input speed n1 and transmission ratio according to the following formula.

n2=n1/i

Transmission efficiency:

The efficiency on the sample refers to the transmission efficiency of the reducer under full load.

Rated output torque:

It refers to the torque (without wear) that the reducer can load for a long time (continuous working system). The conditions shall meet the load safety, and the safety factor is FS = 1; The rated output shaft complies with gear and bearing standards.

Acceleration torque T2b:

It refers to the * * * large torque allowed to be loaded to the output end in a short time when the working cycle is less than 1000 times per hour. When the working cycle is more than 1000 times per hour, the impact factor needs to be considered. T2b is a * * * large value in the selection of periodic working system. The acceleration torque in actual use must be less than the acceleration torque, otherwise the service life of the reducer will be shortened.

Starting torque T10:

Refers to the torque loaded on the reducer to overcome the friction in the reducer;

***High torque T2max:

It refers to the output torque that the reducer can bear under static conditions or frequent starting conditions, usually refers to peak load or starting load.

Actual required torque TR2:

The required torque depends on the actual working conditions of the application, and the rated torque of the proposed reducer must be greater than this torque.

Calculation torque TC2

When selecting the reducer, the actual required torque TR2 and service factor FS can be used. TC2 = TR2 * FS ≤ TN is obtained according to the following formula


FAQ

  • Where is your product mainly exported?

    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 offer you a quote, we will confirm the transaction method with you, FOB, CIF, CNF, etc. For large-scale production, you need to pay a 30% deposit before production and a 70% balance on the copy of the document. The most common way is T/T. Letter of Credit is also acceptable.
  • 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.
