Abstract

The invention relates to the technical field of railway vehicle rim lubricating equipment, and particularly discloses an angle-variable rim lubricating device which comprises an oil sprayer and a fixing support, the oil sprayer is connected with a bogie frame of a railway vehicle through the fixing support, and the oil sprayer comprises a nozzle, a universal rotating device, a filtering device and an oil sprayer oil conveying pipe. The nozzle, the universal rotating device, the filtering device and the oil sprayer oil conveying pipe are sequentially connected and internally communicated, the universal rotating device is connected with the filtering device through a universal rotating structure, and a filter screen is arranged in the filtering device. The inclination angle of the nozzle can be accurately controlled, the relative position between the nozzle and the rim can be strictly controlled, the filter screen is arranged in the oil sprayer, oil-gas mixtures can be filtered, the quality of lubricating grease sprayed to the rim is improved, the corrosion effect of impurities on the rim is reduced, and meanwhile the device is simple in overall structure, easy to disassemble and assemble, and convenient to remove impurities.

Description

technical field [0001] The invention relates to the technical field of rail vehicle wheel flange lubricating equipment. Background technique [0002] With the development of high-speed and heavy-duty railway transportation, the wheel-rail contact conditions have further deteriorated, and there are some problems that need to be solved urgently during the operation of rail vehicles, such as excessive wear of wheel rims, wheel-rail noise, etc. Excessive wheel rim wear leads to frequent wheel turning repairs, which greatly shortens the service life of wheels and increases maintenance costs sharply; wheel-rail noise is the main source of rail vehicle operating noise, and excessive noise will affect the normal life of residents along the road. In order to reduce wheel rim wear and reduce wheel-rail noise, it is necessary to install a certain number of rim lubricating devices on rail vehicles. [0003] At present, existing rim lubricating devices are mainly divided into two types:...
