Advantages and disadvantages of gear reducer and worm gear reducer

1、 Transmission principle:
Gear transmission - it mainly depends on the tooth profile of the driving gear to drive the tooth profile of the driven gear.
Worm gear and worm transmission - mainly depends on the sliding friction on the tooth surface when the driving worm and worm gear mesh, so as to generate relative motion on the tooth surface of the worm gear to realize the transmission.
2、 Advantages of gear transmission:
The reducer case body can transmit the motion and power between any axis in the space, that is, the axis can be parallel, crossed or staggered; Stable rotation, large transmission range, multi-stage gear transmission design, wide application range, long service life and high efficiency (90% ~ 99%), the box body is mainly made of cast iron, with beautiful appearance and compact structure. Under normal conditions, the working ambient temperature is - 10 ℃ ~ 40 ℃. Compared with similar products, this product has the characteristics of wide speed change range, compact structure and convenient installation. It can be widely used in the speed reduction mechanism of various mechanical equipment such as metallurgy, mining, hoisting, light industry, chemical industry, transportation, construction and so on.
3、 Disadvantages of gear transmission:
Gear, box processing equipment, gear grinding process and assembly technology are more stringent, resulting in high manufacturing cost. Gear transmission has no overload protection and self-locking performance. It needs to be additionally equipped with brake device, relatively loud noise, small single-stage gear transmission speed ratio (generally no more than 1:7), etc. liquid lubricating oil must be added.
4、 Advantages of worm drive:
The single-stage reducer can obtain a large transmission ratio (generally 5 ~ 100), compact structure, and can be used with lubricating oil or grease. The transmission is stable, the noise is small, and the large speed ratio can realize self-locking performance. The connection of small single-stage + large single-stage reducer can increase the total speed ratio and torque. The application range can be further increased and the manufacturing cost is relatively low.
5、 Disadvantages of worm drive:
The transmission meshing efficiency is relatively low, and the greater the speed ratio, the lower the efficiency. It can only be in the form of straight and vertical output, which has certain restrictions on the application, the complex process of worm gear cast copper material and the high cost of small batch production.
RV worm gear reducer
The helical gear reducer cannot be self-locking, that is, the driven variable driving and the active variable driven; while the worm gear reducer can be self-locking, which can only be worm driving and worm gear driven, which is irreversible. Moreover, the former allows long-time operation and the latter does not allow long-time operation. The former has high transmission efficiency and the latter has low transmission efficiency, which means that the former has low heating and the latter has high heating, More lubrication is required.

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.
