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.
Claims10
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.
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.
