Large motor bearing fault diagnosis device

Abstract

The invention discloses a large motor bearing fault diagnosis device that comprises a bearing diagnosis structure, a diagnosis gun protection structure and a line pipe support structure; the bearing diagnosis structure comprises an upper box cover, a box base, a diagnosis gun barrel and a diagnosis earphone. The upper box cover and the box base are connected and fixed through a rotating shaft. Thediagnosis gun barrel and the diagnosis earphone are both clamped and fixed in the box base. The line pipe support structure is fixed to the tail end of a gun barrel of the diagnosis gun. A diagnosisgun handle is arranged on one side of the diagnosis gun rod; according to the invention, the diagnosis gun protection structure is fixed to the outer side of the diagnosis gun handle; after a user holds the diagnosis gun handle, the hand of the user can be supported, the fatigue feeling of the user is relieved, meanwhile, the diagnosis gun is prevented from falling off, and the bearing diagnosis structure is safer to use. And a line pipe supporting structure is arranged at the tail end of the diagnosis gun barrel and corresponds to the diagnosis gun line pipe, so that the line pipe can be supported, and the service life of the line pipe is prolonged.

Description

technical field [0001] The invention belongs to the technical field of bearing diagnosis devices, and in particular relates to a large-scale motor bearing fault diagnosis device. Background technique [0002] The bearings of large motors will have various problems after long-term use, such as: bearing leakage, bearing wear and bearing insufficient lubrication, etc., and the commonly used method for bearing fault diagnosis devices is ultrasonic inspection. [0003] However, the existing ultrasonic motor bearing fault diagnosis device still has some unreasonable factors in the process of diagnosing the motor bearing fault. The diagnostic gun is prone to bumping and other accidents when operating the diagnostic gun. There is no good protective device to support the diagnostic gun, and the top of the diagnostic gun is equipped with a diagnostic power cord. The tail of the power cord is frequently bent during normal use. As a result, the wire pipe is easily broken, and the prote...

[0003] However, the existing ultrasonic motor bearing fault diagnosis device still has some unreasonable factors in the process of diagnosing the motor bearing fault. The diagnostic gun is prone to bumping and other accidents when operating the diagnostic gun. There is no good protective device to support the diagnostic gun, and the top of the diagnostic gun is equipped with a diagnostic power cord. The tail of the power cord is frequently bent during normal use. The wire tube is easy to break, and the protection of the root of the wire tube is not enough
