Aiming at different measurement methods, after in-depth research, Haozhi has carried out a large number of horizontal evaluation tests for many brands of products, including impact resistance test, precision life test, and stiffness life test. Four mainstream brands of harmonic reducers in the market were selected for the horizontal evaluation tests. The models and test parameters were all in line with the SHG-20-50-2uh of the industry benchmark HarmonicDrive (hereinafter referred to as "HD").Impact resistance life test
Test conditions: Apply the maximum momentary allowable torque to the harmonic reducer until the reducer is broken and cannot turn. At this time, consider the impact resistance times of the reducer, which is equal to the number of deformations of the wave generator.
The horizontal evaluation test results are as follows:
Impact resistance test (impact torque: 126N.m)
Number of impacts (unit: ten thousand times)
Test conditions: Apply continuous rated load torque to the output end of the harmonic reducer, and the input end operates continuously at 1000RPM, considering the transmission precision after different operating hours.The horizontal evaluation test results are as follows:
Horizontal evaluation test of precision life
Test conditions: Apply continuous rated load torque to the output end of the harmonic reducer, and the input end operates continuously at 1000RPM, considering the torsional stiffness value K1 of the reducer after different operating hours.The horizontal evaluation test results are as follows:
Horizontal evaluation test of stiffness life
From the horizontal evaluation test results, Haozhi's harmonic reducer is in the forefront of the industry in terms of the impact life, precision life, stiffness life and other life performance, which are comparable to HD product standards.
