| Abstract: | Quick-return characteristic is the important character of plane four-bar mechanism,however,the included angle of extreme position plays the decision role in quick-return characteristic.Aiming at the defect existed in the existing definition,the paper exactly described the definition of plane four-bar mechanism and the included angle of extreme position.And the possible value-selective scope of travel-velocity ratio coefficient was also analyzed in the paper. |
