Problems solved by technology

[0002] The existing gear types are rich, including spur gears, helical spur gears, straight / helical bevel gears and spiral bevel gears, etc. Although there are many types of gears, each gear has a single structure, and most of the teeth and gear bodies are a whole, indivisible
Therefore, when carrying out the vibration analysis test of meshing transmission under different gear damage degrees, it is necessary to provide a large number of gears with different damage conditions to simulate various test conditions, and most of the damaged gears after the test have no use value, so not only the test cost is relatively high High, and cause a waste of resources

Abstract

The invention relates to the technical field of mechanical test platform manufacturing, in particular to a combined gear device for a test. The combined gear device is reasonable in structure, low in cost and particularly suitable for a vibration and noise test of meshing transmission of a gear under the condition that the gear is damaged so as to improve the analysis and research efficiency of the vibration and noise of the meshing transmission of the gear. The combined gear device for the test is provided with a gear body and gear teeth. The combined gear device is characterized in that a gear tooth mounting groove is formed in the gear body, the gear teeth are embedded and fixed in the gear tooth mounting groove, and each gear tooth is composed of more than two sub-teeth which are continuously arranged in the width direction of the gear teeth. The combined gear device can be widely used in tests researching the vibration and noise of gears under different damage conditions, resources can be saved, and the test cost can be greatly reduced.
