제안 방법
- A high speed electric-hydraulic servo-controlled fatigue tester(with a constant loading weight of 2, 500 kgf, an operating frequency of 40 Hz, and hydraulic pressure 210 kgf/cm2) was employed for bending fatigue tests on the gears. The details of the test are shown in Fig.
- In addition, fatigue tests were performed on gears in order to obtain bending fatigue strength and to observe the effects of the shaving process and shot peening on fatigue strength. Finally the mechanical properties of test gears used in this study were applied to the estimate formula7) of gear fatigue strength so as to check if this formula may be applicable to the test gears.
- In this study formula (2) was utilized to calculate the relation between test load and the actual stress on the teeth risk section.
- 1 and 2, respectively. Shot-peening was performed in order to investigate the effect of shot-peening on the fatigue strength of the gears.
- The purposes of this paper are to evaluate the performance and applications of shaving gears, which are manufactured in the greatest number and to investigate the mechanical properties of the gears manufactured in conventional gear treatment processes so as to understand the effects of the shaving process and shot peening on compression residual stress of the gear's surface hardness layer and the teeth risk section.
대상 데이터
- This study was supported by the Brain Korea 21 Project & ReCAPT, Gyeongsang National University, KOREA.
이론/모형
- 4, and used estimate values on a variety experimental results. The surface residual stress σR of all test teeth were measured by diffraction method(SMX-50). The measurement results" ) are also shown in Table 4.
