Non-Repair Dynamically Balanced Device of Wheel Set in Vehicles

摘要

In order to make the mass distribution of the wheel set symmetrical about the axis of the wheel axle, which is able to remove the periodical exciter source and many consequences coming from it, including having negative effect on the stationarity and stability during the running of the train, shortening the lifetime of the wheels, bearings and many other parts of the train, design a set of balanced device to regulate the mass center of the wheel set. The set of device collects data by relevant detection devices in order to find the mass distribution condition, and then regulate the circumferential positions of the objects with a certain mass in the tapered groove which can make the mass distribution of the wheel set symmetrical about the axis of the wheel axle. The device has many advantages, such as simplicity, high precision, excellent regulating effects, and, at the same time, conquers the disadvantages of many other ways. For the time being, the means to solve the problem are mainly Adding Weight Method and Removing Weight Method, which both cause physical damage to the wheel. Furthermore, these two methods have a lot of disadvantages, such as low stability, limited effect, limited repairing numbers and high labor strength. The device not only conquers these disadvantages of the two methods, but also has many advantages, and in the future, it can be automatically controlled by microcomputers. Wheel sets are very essential to the running of the train, whose quality has outstanding effect on the safety and quality of the running of the train, especially in the condition that trains run faster and faster, which requires wheel sets to meet higher standards on dynamic balance, especially for new high-speed bogie. Thus, the device has a large economy benefit and society benefit.
