Abstract
A load balancing system for rotating members such as vehicle wheels and engine flywheels. An annular groove or recess in the wheel or flywheel receives a length of flexible tubing joined to form a continuous annular ring. The ends of the tube are secured by a sleeve. The tube is partially filled with a balancing fluid mass such as a mercury or small metal balls in a viscous fluid such as silicon. To protect the tube, a sealant is injected into the groove or recess.
Claims11
A method of balancing a generally circular rotating member comprising:
- (a) providing an annular recess in said rotating member concentric about the axis of rotation;
- (b) providing a length of flexible tubing having passageway;
- (c) partially filling said passageway with a fluid mass that will shift therein to compensate for imbalance and vibration;
- (d) applying a sleeve over the abutting ends of said tubing and shrink fitting a sleeve onto the abutting ends to form a continuous ring having a generally circular passageway containing the fluid mass;
- and
- (e) placing said ring in said recess and applying a protective material over said ring in said recess.
A balancing member for balancing a generally circular rotatable member having a recess therein concentric about the axis of rotation, said member comprising:
- (a) a flexible tubing section having ends formed into a continuous ring defining an internal passageway and configured to seat in said recess the ends of said tubing abutting and secured by a shrink fitted sleeve and reinforced by a substantially rigid tubular member in said passageway at said abutting ends;
- (b) a fluid mass in said passageway shiftable in response to motion to counter imbalance and vibration;
- and
- (c) a protective material overlying said tube in said recess.
A balancing member for rotating a shaft comprising:
- (a) a coupling having a body engageable about said shaft;
- (b) a generally circular flange extending from said body defining an annular recess;
- (c) a flexible tubing section having opposite ends formed into a continuous ring defining an internal passageway seated in said annular recess the ends of said section abutting and joined by a shrink fitted sleeve;
- (d) a fluid mass in said passageway shiftable in response to motor to counter imbalance and vibration.
A balancing member for a vehicle wheel having a bolt circle, said member comprising:
- (a) a generally circular plate having a bolt circle matching the bolt circle of said wheel and having an annular channel adjacent the periphery thereof;
- (b) a flexible tubing section having opposite ends and formed into a continuous ring defining an internal passageway and seated in said channel the ends of said section abutting and joined by a shrink fitted sleeve;
- and
- (c) a fluid mass in said passageway shiftable in reasons to motion to counter imbalance and vibration.
