When the planetary reducer is running at high speed, the temperature and pressure changes in the inner cavity directly affect its load rate, continuous rotation speed and service life.In order to ensure that the input end and output shaft of the planetary reducer are sealed bearings and sealing rings, but the sealed bearings and sealing rings will also affect the temperature and pressure changes in the internal cavity of the reducer.Therefore, under the premise of considering the cost, it is necessary to consider that moderate is to reduce temperature and blood pressure.The temperature and pressure limit the maximum rotation efficiency of the planetary reducer to 98%, and 2% of the input energy is turned into heat and lost.This kind of damage mainly comes from the friction of the sealing ring and the bearing, which will increase the temperature of the inner cavity of the planetary reducer.Sometimes the relatively high natural ambient temperature outside will also increase the temperature of the internal cavity of the reducer.The temperature of the inner cavity of the reducer immediately limits the output torque and output speed ratio.
There are many ways to reduce the pressure in the inner cavity of the planetary reducer:
One is to reduce the grease in the internal cavity of the planetary reducer model, but this may affect the long-term efficient operation and service life of the reducer.The grease will continue to move around after the reducer has been running for a period of time, which will cause the grease on the sun gear and planetary gear of the planetary reducer. As a result, the bearing capacity of the reducer will decrease during high-speed operation, which will reduce the rated output torque. .
The second is to discharge the high-pressure gas inside the reducer to the outside of the reducer.However, it is necessary to ensure the safe operation of the reducer, and according to environmental protection regulations, no oil, welding fumes, etc. should be discharged to the outside world. In addition, IP65 moisture-proof, anti-fouling, waterproof and other safety protection regulations must be considered.Of course everyone thought of adding unilateral valves.But this is not suitable for planetary reducers with small size, high load rate, high rotation efficiency and high reliability.
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.
