Internal balance correction device for vehicular driveshaft assembly
View Patent ↗A balance correction device is supported within a hollow article, such as a driveshaft assembly for a vehicular drive train system, to balance the article for rotation. The balance correction device includes a first disc having a first slot provided therein and a second disc having a second slot provided therein. Portions of the first and second slots are axially aligned with one another. An object, such as a ball, is received within the axially aligned portions of the first and second slots. The first and second discs can be positioned relative to one another to position the object relative to the unbalanced article to balance the unbalanced article for rotation.
1. An assembly that is balanced for rotation comprising:
a hollow article that is unbalanced for rotation; and
a balance correction device supported within said hollow unbalanced article, said balance correction device including a housing that is supported within said hollow unbalanced article, a first disc disposed within said housing and having a first slot provided therein; a second disc disposed within said housing and having a second slot provided therein; and an object disposed within said housing and received within said first and second slots, wherein said first and second discs are positioned relative to one another to position said object relative to said unbalanced article to balance the assembly for rotation.
2. The assembly defined in claim 1 wherein said first slot extends generally linearly.
3. The assembly defined in claim 1 wherein said second slot extends generally arcuately.
4. The assembly defined in claim 1 wherein said first slot extends generally linearly, and wherein said second slot extends generally arcuately.
5. The assembly defined in claim 1 wherein said object is a ball.
