Not necessarily.
- Smaller backlash will lead to thermal expansion of gear teeth under high-load operation, resulting in gear jamming, sharp temperature surges, and abnormal noise. In severe cases, tooth fracture may occur.
- Excessive backlash will trigger violent impact and vibration when the gear switches between forward and reverse rotation. It will increase equipment vibration and noise, and accelerate fatigue wear on tooth surfaces.
Our engineering team will formulate a reasonable backlash range according to your actual working conditions before production, instead of simply pursuing extremely tight tolerance values.
