Abstract
A method of balancing a set of rotating turbine elements includes measuring imbalance in the rotating elements; adding or removing material to or from at least two correction planes in the turbine set at an angular location measured during the imbalance measurement; and, if necessary, repeating said steps of measuring and removing until a predertermined balance is achieved.
Claims4
A method of balancing a set of rotating turbine elements, comprising the steps of:
- measuring imbalance in the rotating elements;
- adding or removing material to or from at least two correction planes in the turbine set at an angular location measured during the imbalance measurement;
- and, if necessary, repeating said steps of measuring and removing until a predertermined balance is achieved.
A method of balancing the rotating turbine set elements in a dental handpiece having rotating bur tube having a rotation axis, the bur tube having a bur receiving end and an opposite cap end, comprising the steps of measuring the imbalance in the rotating elements;
- adding or removing material from at least two correction planes in the turbine set at an angular location measured during the imbalance measurement;
- and, if necessary, repeating said steps of measuring and removing until a predertermined balance is achieved;
- wherein said two correction planes are perpendicular to the rotation axis of the burtube, and wherein a first said of said two correction planes intersects the bur tube near the bur end, and a second of said two correction planes intersects the bur tube near the cap end.
A method of balancing dental handpiece rotating turbine set elements having an axis of rotation, the set including a rotating bur tube having a rotation axis, the bur tube having a bur receiving end and an opposite cap end, comprising the steps of measuring the static and coupling imbalances in the rotating elements;
- removing or adding material from at least three different locations along the axis of rotation of the turbine set;
- said step of removing or adding material including removing or adding material from a two ends to reduce couple imbalance and from a middle or intermediate location there between reduce static imbalance.
