Problems solved by technology
Flywheels can be used to reduce speed fluctuations during mechanical operation; in order to make machinery run smoothly, flywheels are widely used in machinery. Existing mechanical equipment, especially presses, often need to be shut down for maintenance and repair during the working process ;After the machine tool is shut down, due to the inertia of the flywheel rotation, it takes more than ten minutes to completely stop running, which makes the maintenance personnel wait for a long time, which affects the machine tool maintenance cycle and production efficiency
Existing braking devices that solve the flywheel's rotational inertia generally use frictional braking from the outside. Because the inertia of the flywheel is too large, the friction force generated is huge and affects the service life of the braking device. structural reform

The invention discloses an impeller braking type flywheel. According to the impeller braking type flywheel, an impeller rotating in the reverse direction is arranged in a flywheel body, and the impeller rotates so as to drive liquid in the flywheel to rotate in the direction opposite to the rotating direction of the flywheel, so that the flywheel is braked. The impeller braking type flywheel is simple in structure and extremely ingenious; in addition, conventional friction braking is not adopted, and thus damage to machines is avoided.
Description
technical field [0001] The invention relates to a novel structure of a flywheel, especially a flywheel that requires frequent braking. Background technique [0002] The flywheel is a wheel-shaped accumulator with a large moment of inertia installed on the rotary shaft of the machine; it is generally a cast iron disc with a large mass. When the machine speed increases, the kinetic energy of the flywheel increases to store energy; when the machine When the speed decreases, the kinetic energy of the flywheel is reduced and the energy is released. Flywheels can be used to reduce speed fluctuations during mechanical operation; in order to make machinery run smoothly, flywheels are widely used in machinery. Existing mechanical equipment, especially presses, often need to be shut down for maintenance and repair during the working process After the machine tool is shut down, due to the inertia of the flywheel rotation, it takes more than ten minutes to completely stop the operati...
