Description

Technical Field

[0001] The utility model relates to the technical field of diesel engines, in particular to a vibration-absorbing and loose-proof diesel engine gear chamber cover. Background Art

[0002] The gear chamber cover is mainly used to seal the gear chamber on the diesel engine to prevent dust and rainwater from entering the gear chamber. When the traditional gear chamber cover is connected to the engine body, the gear chamber cover is easy to loosen from the engine body due to the vibration state when the engine is working. The traditional connection measure is to place a layer of rubber pad between the fitting surface of the gear chamber cover and the engine body to achieve buffering, anti-loosening and sealing effects.

[0003] For example, the Chinese utility model provides "a shock-absorbing and anti-loosening diesel engine gear chamber cover", and its announcement number is: CN217328385U. The utility model performs shock absorption and buffering after installation: after the gear chamber cover and the engine body are installed, the nylon shock-absorbing gasket is arranged between the installation fitting surfaces of the gear chamber cover and the engine body. When vibration occurs between the gear chamber cover and the engine body, the nylon shock-absorbing gasket will be squeezed, and the nylon shock-absorbing gasket will receive the extrusion force and transmit it to the sealing oil inside the sealing oil tank. The sealing oil is transmitted to the inside of the oil storage cylinder seat through the liquid guide channel, and the shock-absorbing spring inside the oil storage cylinder seat performs shock absorption and buffering. At the same time, the sealing oil itself can also produce a certain buffering effect during the transmission of the extrusion force. However, in actual use, this patent does not have a protective structure and has a low intensity of use. The gears often shake during operation, and the gear chamber cover collides with the outside world, which will damage the gear chamber cover over a long period of time, making it unfavorable for actual use. Utility Model Content
