ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a self-compensating dynamic balancer, and more particularly, to a process and a self-compensating dynamic balancer providing an improved structure to reduce the effect of a frictional force.
Description of the Related Art
In a typical rotating body, the center of rotation and the center of gravity of the rotating body, do not match due to eccentric mass caused by an error during the manufacturing process. I have noticed that when the rotating body having a center of rotation which does not match the center of gravity rotates, the center of rotation revolves, i.e., whirls. As a result, internal vibrations are generated in the rotating body, particularly in a radial direction.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved self-compensating balancer and process for self-compensated balancing of rotating devices.
It is another object to provide a self-compensating dynamic balancer which restricts deterioration of balancing capability due to a frictional force by adjusting the number of rigid bodies disposed in the race.
It is further object to provide an improved self-compensating dynamic balancer with lubricant covering the surface of said rigid bodies and said race to reduce the friction between said rigid bodies and said race.
These and other objects may be achieved with a self-compensating dynamic balancer with: a main body installed at a rotating body to restrict internal vibrations due to eccentric mass of the rotating body and having a circular race formed therein around a rotation shaft of the rotating body; and a plurality of rigid bodies disposed in the race to be capable of moving freely, wherein there are as many rigid bodies as necessary to occupy at least half of the inner space of the race.
