The double-headed chamfering machine is widely used in the thermal power plant pulverizing system. In the previous period, our plant's pulverizing system was also plagued by these two defects, which even affected the fuel supply of the unit. , The effect is remarkable, but the oscillation of the transmission shaft and the broken tooth of the small cone have always troubled the safe production of the system, and the oscillation of the transmission shaft is less than 0.08mm.
Specific measures of double-head chamfering machine:
1. Insufficient tightening force of the large gear ring is also one of the important reasons for its deformation. In practice, in addition to increasing the tightening force of the bolts, connect the large gear ring joint surface with 10mm thick steel plate, increase the fastening surface, avoid the deformation of the gear ring, ensure that the angular velocity of the main and driven wheels are common, and avoid the change caused by the transmission ratio. The inertial force of the fatigue fracture.
2. The sufficient smoothness of the transmission shaft bearing is also the main reason for ensuring its smooth operation. The use of traditional timing and technical refueling can ensure that the bearing is sufficiently smooth, but it is easy to form excessive or insufficient smooth oil. It is recommended Use mechanical timing and quantitative to make up for the smooth grease scientifically, so as to ensure the moderate smoothness of the bearing, reduce the oscillation, avoid the wear of the bearing and the breakage of the cage, and extend the life.
3. The tooth tip clearance is one of the important assembly parameters of the gear transmission device. In the regulations, the gap between the large and small cones is 7.5-8.5mm. In practice, the equipment is operated for a long time, and the large gear ring gear is deformed by stress and impact. The original circular gradual change is ellipse, so the tooth tip gap is even less than 6mm. During the practice adjustment, the tooth tip gap should be adjusted to 8.5-10mm to reduce the impact caused by the tooth tip gap and form gear tooth overload. Break.
The above is to introduce you all the contents of the double-head chamfering machine, I hope to help you.
