Balance Shaft

In piston engine engineering, a balance shaft is an eccentric weighted shaft which offsets vibrations in engine designs that are not inherently balanced (for example, most four-cylinder engines). They were first invented and patented by British engineer Frederick Lanchester in 1904.

Famous quotes containing the words balance and/or shaft:

    If when a businessman speaks of minority employment, or air pollution, or poverty, he speaks in the language of a certified public accountant analyzing a corporate balance sheet, who is to know that he understands the human problems behind the statistical ones? If the businessman would stop talking like a computer printout or a page from the corporate annual report, other people would stop thinking he had a cash register for a heart. It is as simple as that—but that isn’t simple.
    Louis B. Lundborg (1906–1981)

    The subterranean miner that works in us all, how can one tell whither leads his shaft by the ever shifting, muffled sound of his pick?
    Herman Melville (1819–1891)
