Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine manufacturing, in particular to a novel crankshaft gear ring hoisting tool. Background Art

[0002] The production process of high-power medium-speed engines involves the installation of crankshaft gear rings, which are gear rings with mounting holes. The gear rings are installed on the crankshaft, and the hollow part in the middle of the gear rings matches the circumferential step surface of the crankshaft and is fixed by bolts and nuts. The gear ring is a key component of the diesel engine timing system, with a large mass and difficult to adjust.

[0003] There was no special lifting tool for the crankshaft ring gear installation. During installation, a lifting belt was usually used to lift the ring gear around the ring gear. In order to avoid interference with the crankshaft during installation, the ring gear was not fixed in any axial direction during lifting. This resulted in unsafe and unstable lifting, and the lifting belt adjustment time was long during lifting, resulting in low installation efficiency. Utility Model Content
