Description

Technical Field

[0001] The utility model relates to the technical field of crankshaft processing tooling, in particular to a tooling for assisting the installation of a crankshaft gear ring. Background Art

[0002] When it is impossible to use equipment to press-fit the crankshaft gear ring in a working environment, the heated gear ring needs to be manually installed. In the prior art, the gear ring and the crankshaft are positioned by aligning the upper platform with the line. This method has no keyway or positioning point, so the positioning cannot be accurate and the angular assembly requirements cannot be guaranteed. As a result, the angle of the assembled gear ring cannot be meshed with the gear at a predetermined angle, resulting in low assembly quality, high scrap rate, and increased production costs.
