Balance gear top surface side of the positive direction of rotation of wear, the other side has a slight wear. Entire bottom teeth are formed at a surface wear from the addendum, wear cut recessed section. Great gear tooth wear and balance is basically the same. All forward tooth surface pitting approached or exceeded clever.
This set of center drive mill equipment was purchased years from Shanghai, running for two years began to see the tooth surface pitting, after increasing year by year. After analysis, the main reason is two-fold aspect of vibration is tooth surface pitting and wear, tooth lateral gap increases, causing lower degree of coincidence.
On the other hand is between bearing rolling elements, appears in speed between the shaft and the bearing sleeve to cause the gap. Feasibility analysis, we reverse gear, mainly from four aspects of the analysis of the reducer with the motor, the mill is the center of the drive. From sports mechanics of speaking, before and after inversion, the same as any with a little force, the same moment, in the opposite direction. From the perspective of Engineering Mechanics, axle transfer power constant, constant speed shaft torque remains unchanged.
It can be reversed. All the teeth are cylindrical gear reducer, the structure itself with citrus. Although the forward flank damaged, but the reverse tooth surface largely intact. When reversed, the reverse pitch change, modulus change, constant pressure angle. Another, the entire gear from both positive and negative tooth surface, using the same heat treatment, hard tooth surface, the same abrasion resistance, tooth core toughness, strength tooth surface intact. The inside of the gear unit itself installed prescribe tanks, one forward, one backward.
Installation reverse key aim is to prevent damage to the motor reverse forward key, so that two-way checks. It is not difficult to understand the feasibility of reversal. The foregoing analysis has had the reverse gear condition. Preparations reversal reversal preparation work includes repairing the gearhead, oil changes and changes related positions due to the impact mill reversing the direction of movement of the material. Reducer main aspects to do the work of the entire internal body cleansing gear grinding replace the top two south-speed shaft bearing clearance larger model families, continued on page short, clinker cooling is not good, high temperature. Under high temperature conditions, regardless of the type of number will not wear steel. Tooth breakage caused by overhead and tower, distortion.
