As shown in fig. 5 and 14, the speed reducer according to the present embodiment includes a speed reducer housing 6 and an external vibration state monitoring device according to embodiment 2 or 3, the speed reducer housing 6 has a second inner cavity for containing oil therein, an open end of the oil containing cavity is hermetically connected to the speed reducer housing 6, and the oil containing cavity is communicated with the second inner cavity.

The application a reduction gear, including retarder housing 6 with as this application external vibration state monitoring devices, during the use, external vibration state monitoring devices is external to the reduction gear to hold chamber and the internal intercommunication of reduction gear with fluid, the during operation, only need hold chamber and the internal intercommunication of reduction gear with fluid, fluid can get into fluid and hold the chamber in the reduction gear, then recycle all install in on the pedestal fluid level detector 41 and temperature sensor 42 gather fluid and hold the corresponding data of fluid in the chamber to realize the collection of a certain section of fluid level data of fluid in the reduction gear and the collection of fluid temperature data.

Meanwhile, as the external vibration state monitoring device is externally connected to the speed reducer, the vibration of the speed reducer can be transmitted to the base body, so that the vibration data of the external vibration state monitoring device can be acquired by the vibration sensor 43 on the external vibration state monitoring device.

To sum up, this application a reduction gear, its external connection vibration state monitoring devices do not occupy the reduction gear inner space promptly, need not carry out great change to reduction gear structure, can realize the vibration data acquisition of a certain section liquid level data of fluid in the reduction gear, fluid temperature and reduction gear moreover again.

Preferably, the reducer housing 6 is provided with a fuel level indicator port 61 for matching with the visual fuel level indicator 26, an open end of the oil liquid accommodating cavity is communicated with the fuel level indicator port 61, and the housing 24 is provided with the visual fuel level indicator 26 for displaying the oil amount in the first inner cavity 247.

This application a reduction gear, external vibration state monitoring devices that has on its oil pointer mouth 61, do not occupy the reduction gear inner space promptly, utilize the oil pointer mouth 61 of reduction gear, need not change reduction gear structure, can realize the vibration data acquisition of a certain section liquid level data of fluid in the reduction gear, fluid temperature and reduction gear moreover again.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
