Abstract

The invention provides a fixed connecting piece of a fan. The fixed connecting piece of the fan comprises a connecting disc, a first cover plate, a first rubber gasket, a second rubber gasket and a second cover plate, wherein the outer end of the connecting disc is connected to a crankshaft pulley; the inner side of the connecting disc is connected to the first cover plate; the first rubber gasket is arranged on one side, deviated from the connecting disc, of the first cover plate; the second rubber gasket is arranged on one side, deviated from the first cover plate, of the first cover plate; the first rubber gasket and the second rubber gasket clamp a mounting plate at the center of the fan; and the second cover plate is further arranged at one end, deviated from the first rubber gasket, of the second rubber gasket. The fan and a crankshaft are flexibly connected by two rubber gaskets which are simple in structure, so that the influence of torsional vibration on the fan is reduced.

Description

technical field [0001] The present application relates to a fixed connection part, in particular to a fixed connection part of an engine fan thereof. Background technique [0002] The rubber hub structure is currently the most commonly used way to connect the fan and the engine, such as figure 1 The rubber hub structure in the prior art is shown. Due to the large curved surface in the structure, the processing and manufacturing costs increase, and the market generally reflects the effect of the rubber hub with this structure on absorbing the torsional vibration of the engine under working conditions. Poor, relatively poor reliability, resulting in frequent fan blade breakage failures. [0003] Chinese patent CN203223415U discloses a fan damping shaft, including a damping shaft connection plate, the vibration damping shaft connection plate is installed on the front end of the engine crankshaft, the front end of the vibration damping shaft connection plate is installed with a...
