Problems solved by technology

[0008] The engine flywheel has a large moment of inertia, so it has a large mass and diameter. In addition, it is made of cast iron, ductile iron or No. 45 steel, which has a large mass, which makes the transportation and assembly of the engine flywheel time-consuming and laborious; The flywheel is a disc-shaped part, which is inconvenient for hoisting and installation, and it is easy to roll or slip, causing industrial accidents and economic losses

Description

technical field [0001] The invention belongs to the technical field of automobile assembly hangers, in particular, the invention relates to an engine flywheel assembly auxiliary hanger and a method thereof. Background technique [0002] The flywheel is a wheel-shaped accumulator with a large moment of inertia installed on the rotary shaft of the machine. When the speed of the machine increases, the kinetic energy of the flywheel increases and the energy is stored; when the speed of the machine decreases, the kinetic energy of the flywheel decreases and the energy is released. [0003] The engine flywheel is a large disc-shaped part installed on the rear end of the crankshaft of the engine. It has a large moment of inertia and has the following functions: [0004] ① Store part of the energy of the engine's power stroke to overcome the resistance of other strokes and make the crankshaft rotate evenly. [0005] ②Through the clutch installed on the flywheel, the engine is conn...
