Do you know the difference between straight gear and helical gear of planetary reducer?

The planetary reducer is characterized by small size, light weight, high bearing capacity, long service life, smooth operation, low noise, large output torque, large speed ratio, high efficiency, safe performance, etc. It is widely used in lifting and transportation, engineering machinery, metallurgy, mining, petrochemical industry, construction machinery, light industry and textile, medical equipment, instruments and meters, chemical industry, ships, weapons, aerospace and other industrial fields. Planetary reducer has straight teeth and helical teeth. Do you know the difference between them? I have sorted out the following three differences for your reference, hoping to help those who buy planetary reducers.


1、 Different structures


Straight tooth planetary reducer: the internal sun gear, large planetary gear and transmission gear are all straight teeth.

Helical planetary reducer: the internal sun gear, large planetary gear and transmission gear are all helical gears.


2、 Different precision


Straight tooth planetary reducer: the first level accuracy is within 10 minutes of arc, and the precision is 6 minutes of arc.

Helical planetary reducer: the first level precision is about 5 minutes of arc, and the precision is within 1 minutes of arc.


3、 Transmission torque is different from efficiency


Straight tooth planetary reducer: under the same motor shaft, straight tooth gear is used to transmit less torque and lower transmission efficiency than helical planetary reducer.

Helical planetary reducer: under the same motor shaft, the helical gear is engaged, and the transmission torque is larger than that of the straight planetary reducer. The transmission device is stable, with large tensile strength and high efficiency.


In general, the precision of helical planetary reducer is higher and the deviation is lower than that of straight planetary reducer. In fact, the planetary reducer has higher efficiency of the transmission system. On the planetary reducer with large power, it has higher torque and more stable transmission system. The reducer with small output power will also use helical gears to reduce transmission system error.


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.
