Abstract

The invention relates to the technical field of oil seal installation, and specifically relates to a device for installing crank shaft rear oil seal; the device comprises a connecting disk, a sliding gland which is sleeved outside the connecting disk and in slide fit with the connecting disk, and a compressing nut which is matched with a screw hole in the connecting disk after penetrating the sliding gland. In the device for installing crank shaft rear oil seal, the sliding gland acts on the rear oil seal via the connecting disk, thus makes the rear oil seal be uniformly stressed and coaxially guided into the crank shaft end in parallel, thereby guaranteeing the precision of the installation, being able to effectively avoiding the hidden trouble of oil leakage caused by that the rear oil seal is not uniformly stressed during the installation process; additionally, by arranging a limit protrusion on the sliding gland, the depth of installing the oil seal can be determined as needed, thus ensuring the installation position and the installation precision of the oil seal; the device for installing crank shaft rear oil seal is simple, practical, convenient, and simple in installation process, thereby effectively preventing lubrication oil leakage caused by inclined installation and unfulfilled installation or excessive installation of the oil seal.

Description

technical field [0001] The invention relates to the technical field of oil seal installation, in particular to a device for installing a crankshaft rear oil seal. Background technique [0002] The rear oil seal of the crankshaft is the main part of the engine, and the assembly quality of the rear oil seal of the crankshaft has an important influence on the oil pressure of the engine. The existing crankshaft rear oil seal installation method is that after the rear oil seal is sleeved on the crankshaft, the crankcase bolt is manually pressed into the crankcase with a ring tool and then the crankcase bolt is tightened. In the process of pressing the rear oil seal into the crankcase and tightening the crankcase, it is impossible to ensure that the rear oil seal is evenly stressed, and it cannot be installed coaxially in a horizontal state. If the crankshaft is combined, it is difficult to ensure the accuracy and quality requirements of the assembly, resulting in oil leakage fro...
