1、Reviewers comments:Reviewer #1: The revisions are acceptable.Comment 1: define the nomenclature using a table to define the symbolsThe authors Answer:Thanks for the reviewers suggestion, and we use a table to define the symbols.Comment 2: a full description of NSK and NB is required for the 1st time

2、 used.The authors Answer:Thanks for the reviewers suggestion.NSK:NSKCompany Limited in JAPAN. NB:NBCompany Limited in JAPAN.The full description is added in the manuscript.Comment 3: those truments evaluate the bearing quality by measuring peak and RMS values of the bearing vibration signal at the s

3、pectrum of 1 15 KHZ should be change into which evaluate the bearing quality by measuring peak and RMS values of vibration signals in a frequency range from 1 to 15kHzThe authors Answer:Thanks for the reviewers suggestion. Corrected accordingly.Comment 4: Ln 62 right colomn. . very weak, The weak ch

4、aracteristic leads to the high demand for the sensor and the subsequent signal processing method., extremely weak. It means that it needs high performance sensors and effective signal processing methods in order to extract the weak characteristics reliably.The authors Answer:Thanks for the reviewers

5、 suggestion. Corrected accordingly.Comment 5:Ln 1 P2, A string of methods has been developed to extract the weak signals from complicated signals measured by common accelerometers.The authors Answer:Thanks for the reviewers suggestion. Corrected accordingly.Comment 6:Ln 4, p2, These aforementioned m

6、ethods require computational efforts and may not be suitable for online uses.The authors Answer:Thanks for the reviewers suggestion. Corrected accordingly.Comment 7:Ln 6 p2, To reduce the high demand for signal processing and achieve more effective monitoring, the author firstly use more effective s

7、ensors for obtaining signals with high signal to noise ratio(SNR) and subsequently develop more accurate analysis methods.The authors Answer:Thanks for the reviewers suggestion. Corrected accordingly.Comment 8:Ln 23 p2, Therefore, in this paper the eddy current displacement sensor is employed as the

Corrected accordingly.Comment 9:Ln 27, The following content of the paper has four more sections.The authors Answer:Thanks for the reviewers suggestion. Corrected accordingly.Comment 10:Ln 40 Fig.1 (a) illustrates the w

9、orking process of the eddy current sensor which operates based on electromagnetic induction.The authors Answer:Thanks for the reviewers suggestion. Corrected accordingly.Comment 11:Ln 53 . However, bearings with defects will cause burst components in addition to the periodic signal because of the po

10、ssible impacts induced by the local defects.The authors Answer:Thanks for the reviewers suggestion. Corrected accordingly.Comment 12:Ln 58 P2 When defects appear on different parts such as rolling elements and raceways respectively,The authors Answer:Thanks for the reviewers suggestion. Corrected ac

Ln 42 p3 bearing quality can be assessed by detecting The authors Answer:Thanks for the reviewers suggestion. Corrected accordingly.Comment 14:Please explain more the significant waveform diffe

12、rence for the bruised points on the race ways.The authors Answer: Thanks for the reviewers suggestion.The measured eddy current sensor signal is shown in Fig.7. d) is the signal of the bruise on the outer raceway, and e) is the signal of the bruise on the inner raceway.Fig. 7. Signals of five types

13、of bearings d) Bruise on outer raceway. e) Bruise on inner raceway.The waveform of bruise bearing has been changed from the sinusoidal trend to triangle wave, and there are more burrs and impacts on the outer raceway than on the inner raceway.The result of complexity is also different as shown in Ta

We have invited a

15、 well-versedprofessor in England to revise the English of the whole paper. We have pain great attention to revise the whole paper, and almost each sentence is revised.Reviewer #2:Comment 1: Please check the English grammar, sentence structure, and logic in the whole paper. I suggest that you obtain

16、assistance from a colleague who is well-versed in English or whose native language is English.Comment 2: The literature review is ufficient ection 1. On the complexity application of bearings, many works have been done so far as I known. Such asLingli Cui, Jing Wang, Huaqing Wang, Peng Chen, Improve
