Standard formulation background and technology evolution analysis

Background:With the rapid development of robot technology, precision gear transmission devices are core components, and their performance is directly related to the accuracy and reliability of robot operations. The formulation of GB/T 35089-2018 fills the gap in this field in China and promotes the standardized development of the industry.

Technical evolution:From traditional mechanical transmission to modern precision gear transmission, it has experienced multi-dimensional breakthroughs in material science, processing technology and testing technology. Especially in the field of reducers for robots, the technical maturity of harmonic drives and planetary cycloid reducers has been significantly improved.

Test equipment and implementation suggestions

Typical application scenario analysis: torque efficiency test

Case:A smart manufacturing company purchased a batch of harmonic reducers and conducted torque efficiency tests in accordance with GB/T 35089-2018.

Test equipment selection: Select torque and speed sensors that meet the requirements of the standard, and ensure that the sampling frequency is not less than 1kHz.
Test condition control: The ambient temperature is controlled at (23±5)℃, and the shell temperature does not exceed 60℃.
Data processing suggestions: Draw the torque-efficiency curve (as shown in Figure 5), and take at least 5 sets of valid data when calculating the transmission efficiency.
