Patent ID: 7806794

Claim:
A power transmission chain in a power transmission device having conical sheave faces, the power transmission chain comprising: a plurality of links having through holes, wherein the through holes of at least two of said links are aligned; and a pin inserted, along a direction parallel to the length of said pin, through each of said aligned through holes to connect the links, wherein each said pin has a width corresponding to the width of all of said through holes, the width being defined by side edges extending in the direction parallel to the length of said pin, wherein each said pin also has end edges at each longitudinal end of the pin, said end edges being generally angled by a first angle to contact the conical sheave faces, whereby one of the side edges at each longitudinal end of each said pin is longer than the other of the side edges by a predetermined length related to a larger spacing between said conical sheave faces at said one of the side edges as compared to the other of said side edges, wherein the one of said side edges is angled by a second angle from the direction parallel to the length of said pin at said predetermined length, wherein the second angle is opposite the first angle relative to the direction parallel to the length of said pin, such that the width of said pin is less than the width of said through holes over the entirety of said predetermined length, and wherein said pin extends through all of said through holes of said at least two of said links over the entirety of said predetermined length.
