Abstract
Abstract A dynamic balancing machine for particular use in balancing engine crank-shafts, comprising components to simulate imbalancing effects to which the crank-shaft will be subjected in use, and means for adjusting the position of at least one of the imbalance simulating components to allow the machine to be used on different types of crank-shaft with rapid convertibility.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
A balancing machine comprising: means for supporting a part to be balanced for rotation about an axis and lateral movement in a plane called the clearance plane; drive means for rotating the part to be balanced; two components for generating imbalance, each of said components comprising a mass to orbit about an axis which is stationary with respect to the supporting means, each of said masses having a plane defined by its centre of gravity and its axis of rotation, means mounting said masses for rotation about parallel axes while in antiphase relation at least when said planes are parallel, means driving said masses synchronously with the part to be balanced; and means mounting at least one of said components for movement relative to the supporting means.
Claim 2
Dependent Claim
127 words
A balancing machine comprising: means for supporting a part to be balanced for rotation about an axis and lateral movement in a plane called the clearance plane; drive means for rotating the part to be balanced; two components for generating imbalance, each of said components comprising a mass to orbit about an axis which is stationary with respect to the supporting means, each of said masses having a plane defined by its centre of gravity and its axis of rotation, means mounting said masses for rotation about parallel axes while in antiphase relation at least when said planes are parallel, means driving said masses synchronously with the part to be balanced; and means mounting at least one of said components for movement relative to the supporting means.
Claim 3
Dependent Claim
49 words
A balancing machine as set forth in claim 1, wherein said at least one component is a cursor and said means mounting the movable component comprises guide means, mounted for rotation about the axis of rotation about which said cursor orbits, said cursor being slidable along said guide means.
Claim 4
Dependent Claim
30 words
A balancing machine as set forth in claim 1, wherein the movable component comprises of an eccentric collar mounted for rotational and axial translational movement relative to said supporting means.
Claim 5
Dependent Claim
29 words
A balancing machine as set forth in claim 1, wherein the movable component is movable parallel to said axis of rotation of a part supported by said supporting means.
Claim 6
Dependent Claim
24 words
A Balancing machine as set forth in claim 1 and further including control means for adjusting the position of said at least one component.
Claim 7
Dependent Claim
50 words
A balancing machine as set forth in claim 5, wherein said control means comprises at least one jack positioned to abut said movable component when operated, and said jack control means controls the position of the said movable component as a function of the type of part to be balanced.
Claim 8
Dependent Claim
128 words
A balancing machine comprising: means for supporting a part to be balanced for rotation about an axis and lateral movement in a plane called the clearance plane; drive means for rotating the part to be balanced, two components for generating imbalance, each of said components comprising a mass to orbit about an axis which is stationary with respect to the supporting means, each of said masses having a plane defined by its centre of gravity and its axis of rotation, means mounting said masses for rotation about parallel axes while in antiphase relation at least when said planes are parallel, means driving said masses synchronously with the part to be balanced; and means mounting at least one of said components for movement therealong relative to the supporting means.
Claim 9
Dependent Claim
128 words
A balancing machine comprising: means for supporting a part to be balanced for rotation about an axis and lateral movement in a plane called the clearance plane; drive means for rotating the part to be balanced, two components for generating imbalance, each of said components comprising a mass to orbit about an axis which is stationary with respect to the supporting means, each of said masses having a plane defined by its centre of gravity and its axis of rotation, means mounting said masses for rotation about parallel axes while in antiphase relation at least when said planes are parallel, means driving said masses synchronously with the part to be balanced; and means mounting at least one of said components for movement therealong relative to the supporting means.
