Fault diagnosis method of cycloid reducer gearbox

The cycloidal pinwheel reducer gearbox is a basic component with a large amount and a wide range of applications. The scale of use is very wide, but it is also one of the more messy parts in equipment protection and protection, and there are many more messy parts in the process of missed work.

  According to the detection method, the fault diagnosis methods of the gearbox of the cycloid reducer are as follows:

  a. Oscillation detection and diagnosis method uses machine oscillation as an information source, and during the operation of the machine, the operating status of the machine is distinguished through the transformation ratio characteristics of the oscillation parameters.

  b. The noise detection and diagnosis method uses the noise in the operation of the machine as the information source. During the operation of the machine, the operation status of the machine is distinguished by the change of the noise parameters.The essence of this method is the same as the oscillation detection and diagnosis method, because the noise is mainly caused by the oscillation.Although this method is simple, it is easily affected by environmental noise and is not as accurate as the oscillation detection and diagnosis method.

  c. The temperature detection and diagnosis method uses the temperature of the observable mechanical parts as the information source. During the operation of the gear box of the cycloidal pinwheel reducer, the operation status of the machine is distinguished by the change of the temperature parameters.

  d. Acoustic emission detection and diagnosis method Elastic wave occurs in metal parts in the process of wear, deformation and rupture, and the elastic wave is used as the information source. During the operation of the machine, the frequency change characteristics of the elastic wave are analyzed to distinguish the operation status of the machine.

  e. Analysis and diagnosis method of metal content in lubricating oil During the operation of the gear box of the cycloid reducer, the change of the metal content in the lubricating oil is used to distinguish the operation status of the gearbox.

  f. Optical fiber endoscopy skills

  First, use a special fiber optic endoscope to directly observe the surface wear and corrosion of the parts.This technology is less used because it requires a set of imaging systems, is complicated in operation, and has more constraints on oil pollution.
