Rotation advantage of hard tooth surface reducer

The gear of the hard tooth surface reducer is made of high-strength low-carbon alloy steel by carburizing and quenching. The tooth surface hardness is high. The gears are made of NC grinding technology with high precision and good contact. What are its rolling advantages? The following is a specific introduction:
Helical gear transmission is selected for the hard tooth surface reducer, and the power is 0.95-0.98 during closed meshing, The theoretical maximum transmission power is 50000kw; the speed v / (M / s) < = 130; for the double enveloping worm gear pair, under the conditions of high machining accuracy and excellent smoothness, the transmission power can only reach 0.95, but in general worm transmission, the power scale is generally 0.70-0.92. Due to the restriction of heating, the maximum transmission power PI (kw) = 750, but generally 50KW. Now high-speed and large standard wire drawing machines have become the mainstream of the market. During this period, high-power motors are widely used in large standard wire drawing machines. The selection of hard tooth gear transmission mode with high transmission power will bring better economic benefits to users and have outstanding market expectations.
There is a direct relationship between the transmission ratio and the transmitted power, but the larger the transmission ratio, the greater the center distance between gears. The characteristic of large standard wire drawing machine is that the drawing wire diameter is thick, the drawing force is large, and the required drawing power is large, which leads to too large box.
Under the same transmission ratio, the selection of gear transmission can appropriately add transmission stages in order to achieve the expected speed ratio.


  • 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.
