Gear ring is a part that needs to be used in many mechanical equipment. In the process of operation, sometimes it is necessary to replace the new gear ring, and it is also easy to appear the phenomenon of runout tolerance resistance. So, what are the steps to replace the gear ring and the cause of runout tolerance?
Gear ring replacement steps.
1, the old gear ring will be knocked out of the flywheel body with brass rod in cooling condition with multiple points and removed. Before assembling the new gear ring, try to chamfer the teeth one by one with a file to facilitate the engagement and reduce the damage.
2、The gear ring and flywheel are hot press fit with 0.25-0.64 mm interference. When assembling, the gear ring is heated with torch or welding torch, usually 300-400 ° c, hot set on the side of the machined flywheel. Then hammer in or press down with hydraulic press, in order to prevent the gear ring from loosening, it can be fixed by drilling holes every 1200 places and implanting steel pin method.
3、After the gear ring is firmly assembled, the chamfered angle of the gear teeth should also be repaired, pay attention to improve the assembly type, the side of the gear ring with chamfered angle towards the crankshaft installation surface. 200 places are drilled and the steel pin method is planted to be used for fixing.
Gear ring tolerance runout the cause of this phenomenon.
1、When making the gear ring, the quality of the raw material used is very poor.
2、When the gear ring is used as the workpiece spindle on the machine tool, its rotation accuracy is very low.
3、When using the gear ring, the positioning on the tool card is not good.
