How to determine whether the K series gear reducer requires dynamic balance optimization

1、 Preliminary assessment of vibration characteristics

Under no-load/rated load, the radial vibration amplitude continuously exceeds 0.08mm and increases linearly with the increase of speed.

In the spectrum, the 1-fold frequency conversion component accounts for more than 70% of the total vibration energy, and there are no obvious abnormal peaks in the meshing frequency.

During operation, there is a periodic low-frequency buzzing, and there are repeated signs of loosening at the anchor bolts and couplings.

2、 Quantitative indicator benchmarking verification

According to ISO 1940-1 standard, the K series conventional industrial application rotor balance level is lower than G6.3 level.

The measured residual unbalance exceeds 1.5 times the allowable value of the equipment's factory calibration.

After axis alignment calibration, foot fastening, lubrication and oil change, the vibration reduction is less than 20%.

3、 Mandatory determination of adaptability to working conditions

The supporting equipment includes high-precision scenarios that are sensitive to vibration, such as fans and high-speed conveyor lines.

The operating speed of the reducer exceeds 85% of the rated speed, and the continuous operating time is ≥ 16 hours/day.

Recently experienced major faults such as tooth breakage and bearing locking, but did not perform shaft balance correction after repair.
