Abstract
An axial thrust compensation system in high speed helical gear engagement includes a thrust collar fixed to a shaft which carries a gear. The collar includes a peripheral groove. Another gear carrying shaft includes a disc element which engages the thrust collar groove. Axial thrust generated in the respective gears and the shafts due to the driving engagement between the gears will be transferred between the shafts by the collar and disc. In one embodiment, the collar and/or disc is formed in one piece with its shaft, while in another embodiment the collar and/or disc is bolted to its shaft. A further embodiment provides a pair of disc shaped collars spaced from opposite sides of one gear with the collars framing a pair of disc elements fixed to the other shaft.
