Testing principle and method of mechanical efficiency of planetary reducer

The mechanical power of planetary reducer is the main data to be obtained by the system. The calculation method is as follows. The output power of the planetary reducer is divided by the input power of the planetary reducer to obtain the power of the planetary reducer. The mechanical power of planetary reducer is calculated as follows:
Methods: according to gb6404 rules, install a sound level meter at 1m of the separated planetary reducer housing, and test under additional speed and load to find the maximum sound test data. The level gauge evaluates the function of the planetary reducer. The noise shall not be greater than 60dB.
Test principle to calculate the temperature rise of Harmonic Planetary reducer, it is necessary to test the ambient temperature and planetary reducer temperature. According to the working environment requirements of Harmonic Planetary reducer: - 40-55 ℃; Therefore, the test should be carried out at two extreme temperatures (i.e. high temperature and low temperature). The environmental test is carried out in the temperature control box. Thermistor is selected for temperature measurement.
Connect the thermistor lead to the data collection card. After programming with LabVIEW software, the data collected by the data acquisition card will be scaled and converted into temperature signal. Digital display and waveform generation are performed on the front panel. After all, you can get average, peak and real-time temperature waveforms of ambient temperature and reductant temperature.
The test method is to stick the thermistor on the incubator, use the test data as the ambient temperature, place the thermistor on the planetary reducer housing, and use the test data as the planetary reducer temperature. During normal no-load start, it needs to be maintained at - 40 ° C for 2 hours. Under the condition of 55 ° C, it can work normally for about 2 hours with additional speed and additional load, and its heat balance temperature does not exceed 100 ° C (temperature rise of 45 ° C).

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.
