Problems solved by technology

[0004] However, there is no corresponding taper threaded hole for installing the composite sensor 1 on the existing rotary arm axle box on the early subway vehicles. Factors such as the wall thickness and structure of the rotary arm axle box limit the conical thread The opening of the hole makes it impossible to install the composite sensor on the pivot arm axle box body, resulting in the inability to realize the acquisition of the temperature, shock and vibration signals of the axle box bearing, thus affecting the online fault monitoring of the axle box bearing

Abstract

The invention provides a mounting gasket of an axle box composite sensor. The mounting gasket is used for being mounted on an axle box body. The mounting gasket of the axle box composite sensor comprises a body and a mounting hole. The mounting hole penetrates through the body, and the minimum diameter of the mounting hole is not smaller than the maximum diameter of the threaded part of the composite sensor. The inner wall of one side, close to the top surface of the body, of the mounting hole is matched with the conical surface part of the composite sensor. Meanwhile, the invention further provides an axle box which comprises the mounting gasket of the axle box composite sensor. Compared with the prior art, the mounting holes are formed, so that the composite sensor can be partially mounted on the mounting gasket of the axle box composite sensor; therefore, the depth of a mounting hole needing to be formed in the axle box body is reduced, and the composite sensor can be smoothly mounted on the axle box.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a mounting gasket and an axle box for an axle box composite sensor. Background technique [0002] With the advancement of China's science and technology, China's rail transit has developed rapidly. Rail transit is a mode of transportation with the characteristics of large volume, fast speed, safety, punctuality, environmental protection, energy saving and land use, referred to as "rail transit", including subway, light rail, maglev, urban railway, tram, New transportation system and more. In rail transit vehicles, in order to better realize the connection between the wheel set and the bogie frame, and at the same time better transfer the weight and load of the car body to the wheel set, reduce friction and reduce running resistance, the connection between the wheel set and the bogie frame A special axle box is often provided. When the vehicle is running, because the vehic...
