Dalan Motor summarizes the symptoms of 9 bearings of the hydraulic pump motor that are about to fail. How many times do you encounter?

For the long-running hydraulic pump motor, the usual inspection and tracking is particularly important. The test items include the rotation sound of the bearing, vibration, temperature, and the state of the lubricant. Today, Dalan Motor's small series summarizes the 9 bearings that are about to fail. Typical symptoms and countermeasures for everyone to learn.

(1) Dirt, foreign matter, sand or other contaminants enter the tank.

Countermeasure: Clean the bearing housing and replace it with a new one.

(2) Water, acid, paint or other corrosive substances enter the bearing housing.

Countermeasure: Install a protective dust cover to improve the oil seal.

(3) The inner hole of the bearing housing is not round, twisted and deformed, and the supporting surface is not flat.

Countermeasures: Check the bearing housing, adjust the support surface, and adjust the gasket.

(4) The shaft diameter is small or the adapter sleeve is not locked.

Countermeasure: Detect the shaft diameter, select the appropriate amount, and re-lock the adapter sleeve.

(5) Unbalanced load, the box hole gap is large, and the outer ring slips in the box hole.

Countermeasure: Replace the bearing housing that meets the design required aperture.

(6) Two or more bearing couplings, resulting in axial deviation and angular deviation.

Countermeasure: Re-adjust the spacers so that the axes are coupled on the same line.

(7) Incorrect installation, directly hit the bearing with a hammer.

Countermeasure: Standardize the installation of bearings.

(8) The bearing clearance is too large.

Countermeasure: Adjust the bearing clearance.

(9) Equipment vibration.

Countermeasure: Find out the cause of the vibration and do the corresponding treatment.
