The traditional formula for calculating the degrees of freedom of planar mechanisms is based on rigid motion components and is not applicable to the calculation of degrees of freedom of planar mechanisms with flexible or elastic components.Taking the sleeve roller chain transmission pair and toothed belt transmission pair as examples,this paper elaborates on the problems encountered in the calculation of the degrees of freedom of planar mechanisms with flexible or elastic components using traditional formulas for calculating the degrees of freedom of planar mechanisms.Some technical treatments are carried out to define the flexible elastic equivalent constraint as the formula variable,and combined with traditional formulas for calculating the degrees of freedom of planar mechanisms,a formula for calculating the degrees of freedom of planar mechanisms with flexible or elastic components is established,And the correctness of the new formula was verified using examples.
