Causes the Vibration of the Pinion during the Operation of the Gold Rolling Machine

The flank clearance and top clearance of the size gear of the gold-plating machine will cause the vibration of the pinion. Therefore, we must first check whether the flank clearance and top clearance of the large and small gears meet the requirements. The side clearance and top clearance of the gear drive should be appropriate. A certain side and top clearance can compensate for the manufacturing and assembly deviation of the gear, compensate for thermal expansion and form an oil film to prevent jamming. However, too large a gap can cause an impact. If the gap is too large or too small, it will cause additional load, increase the wear of the gear transmission, and even bring accidents. The common method of measuring the gap is to use the lead method.
The rolling mill pinion vibration caused by the unreasonable contact situation of the small gear tooth surface of the gold rolling machine. The two gears that are engaged with the contact area of the gear are expressed as a percentage of the total length of the tooth and the full height of the tooth in the contact portion along the tooth length and the tooth height, and the normal contact surface should be evenly distributed on the working surface of the tooth. If the contact surface is small or the contact position is incorrect, the load will be concentrated and distributed, causing local wear and vibration of the gold compactor.
