What are the advantages and disadvantages of gear reducer and worm gear reducer?

I. Transmission principle:

Gear transmission -- mainly depends on the tooth shape of driving gear to drive the tooth shape of driven gear to achieve transmission; Worm gear drive - drive mainly depends on active worm and worm gear meshing tooth surface of sliding friction, so that the worm gear tooth surface relative movement.

Two, the advantages of gear transmission:

The reducer can transfer the motion and power between any axes in the space, that is, the axes can be parallel, cross or staggered; Smooth rotation, large transmission range, multi-stage gear transmission design, wide application range, long service life, high efficiency (89%~98%), the box is made of cast iron, beautiful appearance, compact structure. Normally, the operating temperature ranges from -10 ° C to 40 ° C. Compared with similar products, the product has the characteristics of wide speed range, compact structure and easy installation. Can be widely used in metallurgy, mining, lifting, light industry, chemical industry, transportation, construction and other mechanical equipment reducer.

Disadvantages of gear transmission:

Gear, box processing equipment, gear grinding process, assembly process and other requirements are more stringent, resulting in high manufacturing costs. Gear transmission without overload protection and self-locking performance, the need to install additional brake device, noise is relatively large, single-stage gear transmission speed ratio is small (generally not more than 1:6), and gear meshing clearance is small.

There is also a big difference between these two types of reducer:

1. Internal structure. The direct difference between the two types of reducer is their internal structure. If it is a gear reducer, the transmission structure inside is gear. As for worm gear reducer, it may be helical worm gear drive, or it may be worm gear drive. Different forms also directly affect efficiency.

2. Efficiency. The internal structure of the two kinds of reducer has a direct impact on its efficiency. If a gear reducer is used, the efficiency of any motor can reach about 90%. If the worm gear reducer is used, the transmission efficiency can reach 75%. So if you need high efficiency and energy saving, choose gear reducer is more appropriate.


  • 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.
