起重机起升机构减速箱齿轮故障诊断

The Fault Diagnosis of the Gear Reducer in the Hoisting Mechanism of Crane.

减速箱是起重机械中使用极为广泛的零部件之一。它的工作状态的好坏直接影响到起重机械的使用效能。从齿轮啮合动力学模型入手 ,论述了齿轮故障诊断原理 。

The gearbox is the most extensive unit used in cranes. The state of the box is effect on the working state of the crane directly. This paper discusses the mechanism of the faults diagnosis for the gearbox, and then it gives an example of the diagnosis.
