Fly shear reducer

Fly shear reducer assembly 

The main drive reducer of the head cutting flying shear is composed of two stages of helical cylindrical gears, a flywheel, and a housing, etc. Among them, the small gear is a forged gear and the large gear is a welded gear. The helical cylindrical gears have the advantages of simple processing technology, high processing accuracy, good transmission efficiency, and convenient assembly and maintenance.

Working characteristics of the main drive reducer of the flying shear 

When the cutting command is received, the motor drives the upper and lower rotors in the fly shear body through the reducer to start working. Each of the upper and lower rotors is equipped with upper and lower cutting blades. The upper and lower cutting blades successively cut into and break the strip billet, then brake and wait for the next cutting. The fly shear has the characteristics of instantaneous and discontinuous operation. When the fly shear blades complete the instantaneous action from cutting into the strip billet to cutting it off, a large cutting force and kinetic energy are required. The kinetic energy required for the fly shear operation cannot be met solely by the fly shear system itself. Therefore, a flywheel is installed on the high-speed shaft of the reducer, and the flywheel on the input shaft of the reducer and the gears at all levels store huge kinetic energy during rotation to supplement the system kinetic energy. 

Working principle of the main drive reducer of the flying shear 

From the above, it can be seen that the lower motor torque and the higher motor speed are transmitted to the input shaft of the reducer through the coupling, and then, through the deceleration and force amplification effect of the two-stage meshing gear pairs inside the reducer, they proceed to... 

The output shaft transmits the higher torque and lower rotational speed to the body of the shearing machine, thereby driving the shearing machine to operate.
