As a traditional transmission system, the internal structure is a worm gear, and the tooth profile is involute.Many consumers of worm gear reducers have very limited understanding of worm gear reducers, not to mention the research on some existing problems. Next, the editor will work with you to understand the analysis of the existing problems of worm gear reducers.
1. The reducer is hot and leaks oil.In order to better improve work efficiency, worm gear reducers usually use non-ferrous metals as the worm wheel, and the worm runs on harder materials.Because it is a sliding friction transmission, more heat will be generated during operation, which will cause differences in thermal expansion and contraction between the parts and seals of the reducer, and then gaps will be generated on each mating surface, and the lubricating oil will become thinner due to the increase in temperature. prone to leakage.There are four key factors that cause this situation. One is the unscientific combination of materials; the other is the poor quality of the meshing friction surface; the third is the incorrect choice of lubricating oil addition; the fourth is poor installation quality and operating environment.
2. Worm gear loss.The worm wheel is usually made of tin bronze, and the matching worm material is hardened to HRC4555 with 45 steel, or 40Cr hardened to HRC5055, and then ground to a roughness of Ra0.8μm by a worm grinder.The wear and tear of the reducer is very slow during normal operation, and some reducers can run for more than 10 years.If the wear speed is fast, it is necessary to fully consider whether the model selection is appropriate, whether it is overloaded, and factors such as the material of the worm gear, installation quality or operating environment.
3. Transmission small helical gear loss.It usually occurs on a vertically installed reducer, and the key is related to the amount of lubricating oil added and the type of oil.In vertical installation, it is very easy to cause insufficient lubricating oil. When the reducer stops running, the transmission gear oil between the motor and the reducer is lost, and the gears cannot get the proper lubrication protection.When the reducer is started, the gears cannot be effectively lubricated, resulting in mechanical loss or even damage.
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 provide you with a quotation, we will negotiate with you: EXW, FCA, FOB, CIF, CRF, DAP Etc. For mass production, you need to pay 30% of the deposit before production and 70% of the balance before shipment. Our most common way is T/T.
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.
