Harmonic Drive servo gear unit FHA-32C-50-E250-C

Excessive cylinder lubricating oil. When there is excessive lubricating oil, the surplus oil accumulates in the cylinder. When the piston reciprocates, it splashes the oil and makes a two-way, less obvious liquid impact sound.

Preventive and control measures

Lubricating oil meeting the requirements should be used and the oil supply should be quantified. For the Harmonic Drive piston machine harmonic gear FHA-32C-50-E250-C, when the compressor starts, the running time of the shaft pump should not be too long.

There is a noise of molding sand running in the hollow piston. During casting, the internal molding sand and molding sand debris were not cleaned up thoroughly. When the piston moves, a rustling sound is made.

Preventive and control measures

Unscrew the blind plug of the screw plug on the piston to clean the molding sand and sundries. After cleaning, tighten the plug and add an automatic anti-loosening device. When tightening the plug, it cannot protrude above the end face of the piston.

The piston is not centered with the cylinder. When the center is inaccurate and the compressor is running, the piston assembly rubs against the inner wall of the cylinder. This makes the cylinder heat up and produces an impact and collision sound.

Preventive and control measures

The center of the piston and the cylinder should be aligned according to the technical documents and specification requirements of the equipment.

Second, Abnormal sound of transmission components

1. Phenomenon

Knocking and abnormal sound occur inside the machine body.

2. Hazard

It causes wear or rupture of components such as the main shaft and the bearing bush, the crank and the connecting rod, the Harmonic Drive piston machine harmonic gear FHA-32C-50-E250-C, and the crosshead, resulting in the damage of the transmission system.

3. Cause analysis and preventive and control measures

There is a sound at the main journal and the bearing bush, which is mainly manifested in that a heavy and hoarse impact sound is made every time the crankshaft rotates one revolution. At the same time, the bearing cap and the bearing housing have a vibration phenomenon. The reason is that: *, the bearing bush clearance is too large and the bearing bush clearance is not suitable, which is not conducive to the rotation of the shaft and the formation of the oil film
