Debt-to-equity ratio On a balance sheet, the formal definition is that debt (liabilities) plus equity equals assets, or any equivalent reformulation. Both the formulas below are therefore identical: Debt to equity can also be reformulated in terms of assets or debt: General Electric Co. () Debt-to-equity ratio The debt-to-equity ratio (D/E) is a financial ratio indicating the relative proportion of shareholders' equity and debt used to finance a company's assets. Closely related to leveraging, the ratio is also known as risk, gearing or leverage. The two components are often taken from the firm's balance sheet or statement of financial position (so-called book
Strain wave gearing the wave generator. The key to the design of the strain wave gear is that there are fewer teeth (for example two fewer) on the flexspline than there are on the circular spline. This means that for every full rotation of the wave generator, the flexspline would be required to rotate a slight amount (two teeth, for example) backward relative to the circular spline. Thus the rotation action of the wave generator results in a much slower rotation of the flexspline in the opposite direction. For a strain wave gearing mechanism, the gearing reduction ratio can be calculated from the
