Abstract
Abstract A universal joint shaft assembly is balanced by weights carried in rings of C-shaped cross section surrounding the assembly adjacent the universal joints and the weights are retained in balancing positions by locally deforming the outer peripheral leg or arm of the C-shaped ring into gripping relation with the weights. Where the weights are made of soft metal, notches of the ring can be pressed into the weights. The C-shaped rings can be anchored to components adjacent the joints of the universal shaft by pressing flaps out of the webs of the rings and securing these flaps to the joint components or can be integral parts of a tube surrounding the shaft.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
75 words
A universal shaft balancing device which comprises a sheet metal ring of C-shaped cross section having an inner peripheral arm adapted to be locked on the shaft, a deformable outer peripheral arm and a web connecting the arms, said C-shaped ring providing an annular groove with an open face at one axial end thereof adapted to receive balancing weights to be locked in the groove by inwardly deforming the outer peripheral arm of the ring.
Claim 2
Dependent Claim
75 words
A universal shaft balancing device which comprises a sheet metal ring of C-shaped cross section having an inner peripheral arm adapted to be locked on the shaft, a deformable outer peripheral arm and a web connecting the arms, said C-shaped ring providing an annular groove with an open face at one axial end thereof adapted to receive balancing weights to be locked in the groove by inwardly deforming the outer peripheral arm of the ring.
Claim 3
Dependent Claim
17 words
The shaft of claim 1 including balancing weights in the form of arcuate segments fitting the groove.
Claim 4
Dependent Claim
18 words
The shaft of claim 1 wherein said ring is an integral part of a tube surrounding the shaft.
Claim 5
Dependent Claim
78 words
A universal shaft having a universal joint component on an end thereof, means on the component defining a deformable annular groove, and a balancing weight in said groove at a position for dynamically balancing the shaft wherein said means defining the deformable groove is a metal ring of C-shaped cross section with an inner peripheral arm anchored on the shaft, an outer peripheral arm deformed locally against the weight in the groove and a web connecting the arms.
Claim 6
Dependent Claim
78 words
A universal shaft having a universal joint component on an end thereof, means on the component defining a deformable annular groove, and a balancing weight in said groove at a position for dynamically balancing the shaft wherein said means defining the deformable groove is a metal ring of C-shaped cross section with an inner peripheral arm anchored on the shaft, an outer peripheral arm deformed locally against the weight in the groove and a web connecting the arms.
Claim 7
Dependent Claim
22 words
The shaft of claim 4 wherein the web of the ring has flaps pressed therefrom anchoring the ring to the joint component.
Claim 8
Dependent Claim
19 words
The shaft of claim 5 wherein the flaps have inward projections adapted to snap lock on the joint component.
Claim 9
Dependent Claim
24 words
The universal shaft of claim 4 in which said outer peripheral arm has an inwardly deformed notch anchoring the balancing weight in the groove.
Claim 10
Dependent Claim
14 words
The shaft of claim 7 wherein the weight has a groove receiving the notch.
Claim 11
Dependent Claim
18 words
The shaft of claim 7 wherein the weight is deformable and the notch is pressed into the weight.
Claim 12
Dependent Claim
19 words
The device of claim 1 having flaps pressed out of the web to lock the ring to the shaft.
