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 present invention relates to the technical field of mechanical test platform manufacturing, specifically a device with reasonable structure and low cost, which is especially suitable for the vibration and noise test of gear meshing transmission under the condition of damage, and further improves the efficiency of gear meshing transmission vibration and noise analysis and research. The combined gear device for the test is provided with a gear body and gear teeth. It is characterized in that a gear tooth installation groove is opened on the gear body, and the gear teeth are fitted and fixed in the gear tooth installation groove. Composed of two or more sub-tooths arranged continuously in the direction, the combined gear for the test of the present invention can be widely used in the test of researching the vibration and noise of the gear under different damage conditions, which can not only save resources, but also greatly reduce the test cost.
