Abstract

To address challenges in the assembly of rear cranshaft oil seals for large-cylinder engines-Including low positioning accuracy, uneven pressing force, and seal damage-The manual pressing device is designed. This mechanism features a mechanical core with a positioning system for Precise alignment between the crankshaft and oil seal, a pressure transmission system ensuring force equilibrium during assembly, and a guiding structure to prevent track deviation. With its user-friendly operation and cost-effectiveness, this solution is ideal for small-to-medium batch production or on-site maintenance, offering a new approach for efficient and reliable assembly of rear crankshaft oil seals in large-cylinder engines.
