Grinders are widely used in coal-fired power plants. However, the vibration of the drive shaft and the broken teeth of the small cones have always plagued the safe production of the system. How to prevent accidents from using the grinder correctly?
The Vibratory Finishing Machine manufacturer has brought specific measures:
The tip clearance is one of the important assembly parameters of the gear transmission. The regulations stipulate that the gap between the large and small cones is 7.5-8.5mm. In actual production, the equipment is subjected to long-term operation, and the large gear ring is subjected to stress and impact deformation. The original circular gradient is elliptical, so the tooth tip clearance is even lower than 6mm. In the actual adjustment process, the tip clearance should be adjusted to 8.5-10mm to reduce the impact caused by the tooth tip clearance and cause the gear tooth overload. Broken.
The insufficient tightening force of the large ring gear is also one of the important reasons for its deformation. In the actual operation, in addition to increasing the bolt tightening force, the large ring gear joint surface is connected by 10mm thick steel plate, the fastening surface is enlarged, the ring gear deformation is prevented, the angular velocity of the main and driven wheels is ensured, and the transmission ratio is prevented from being changed. The inertial force causes fatigue to break.
3, the full lubrication of the drive shaft bearing is also the main reason to ensure its smooth operation, using the traditional regular, manual refueling, although this can also ensure that the bearing is adequately lubricated, but easy to cause excessive or insufficient amount of lubricant, it is recommended It uses mechanical timing and quantitative scientific replenishment of grease to ensure proper lubrication of the bearing, reduce vibration, avoid bearing wear and rupture of the cage, and prolong life.
