The planetary gearbox applied to the hoisting mechanism and the experimental scheme based on powerclosed platform were designed to evaluate the vibration and temperature rise performance of planetary gearbox. The vibration acceleration of planetary gearbox under different working conditions was obtained, and the dynamic characteristics of vibration were analyzed. Then the temperature test was accomplished to gain the temperature rise of critical positions and lubricating oil, and the oil’s temperature accorded with the standards. The experimental results show that the vibration and temperature rise performance of planetary gearbox applied to the hoisting mechanism reaches the requirements.
