5 Signs That Your Gearmotor Needs Inspection
Detecting gearmotor wear early helps prevent costly production downtime. These are the 5 signs that indicate it needs inspection.
Abnormal noise during operation
An unusual humming, whining, or knocking sound that was not present before usually indicates wear in the reducer’s internal gears or bearings. This noise tends to increase over time if it is not addressed.
2. Visible oil leakage
Oil stains on the housing or on the floor beneath the gearmotor indicate a damaged seal, usually on the output shaft or housing joints. Operating with a low oil level accelerates wear on the internal gears.
Excessive housing temperature
A noticeably higher operating temperature than normal can indicate overload, insufficient or degraded lubricant, or a damaged internal bearing generating additional friction.
New vibration in the system
Vibration that was not present before, especially if it is felt in the reducer housing and not only in the motor, is a sign of wear in gears, bearings, or misalignment of the output coupling.
Loss of output speed accuracy
If the driven equipment no longer rotates at the expected speed consistently, it may indicate advanced wear on the internal gear teeth, affecting the system’s effective reduction ratio.
