Abstract
The invention provides a dynamic balance correction structure of a flywheel wheel body in the field of flywheel technology, comprising a wheel body, a pressing component and a faceplate; the wheel body includes a wheel hub, a wheel spoke and a wheel rim, the wheel hub is provided with a central hole, the The center hole is matched and connected with the bearing assembly, and the lower end surface of the wheel rim is the A surface; the hub, the wheel spoke and the wheel rim are assembled and designed with the A surface as the datum plane; the wheel body passes through the pressing component. It is connected to the faceplate, and a cutter is arranged outside the faceplate, and the cutter faces the upper and lower planes and the center hole of the wheel hub with the A surface as a reference to remove weight. The invention is based on the flywheel assembly theory and the coaxiality dynamic unbalance correction theory. By applying the flywheel assembly theory and the initial dynamic unbalance correction technology, the dimensional accuracy and shape and position accuracy of the flywheel body are improved according to the assembly requirements, so as to improve the accuracy of the flywheel movement. The purpose is to improve the initial dynamic balance performance of the flywheel.
Description
technical field [0001] The invention relates to the field of flywheel technology, in particular to a flywheel wheel body dynamic balance correction structure. Background technique [0002] The flywheel body is an important part of the flywheel to output the moment of inertia. The characteristics of the moment of inertia are directly related to the stability and accuracy of its movement. balance. The greater the deviation between the rotating shaft and the inertial spindle, the worse the dynamic balance performance will be, which will affect the accuracy and stability of the wheel body motion and the normal operation of the flywheel. An unbalanced wheel creates a stress on its supporting structure and the wheel itself during its rotation and causes vibrations. Therefore, in theoretical design, the rotating wheel body hopes that its axis of rotation coincides with the main axis of inertia, so as to improve the accuracy and stability of the movement. [0003] For a flywheel ...
