- Abstract:
-
After making the center curve and dot curve of Bourmeist, according to the kinetic requirements γmin>40°~50°, the crank slider mechanism is designed, the inflection point circle is found, and the relationship between slippage, guide inclination angle and inflection point circle is obtained. The position of the slider articulation point B1 is related to the β of the slide guide angle, while the inflection point circle K1 is independent of the β the slide guide angle. The inclination angle of the slider guide can be adjusted appropriately β and the inflection point circle is unchanged, and the position of point B1 is changed on the inflection point circle K1 to meet the design requirements. For the calculation example, when the value of A is <-17, the point on the center curve cannot be obtained, which is consistent with the theory of the Bulmeister center curve, that is, for any given four relevant positions in the plane of the connecting rod, only some corresponding center points can be found on the plane of motion of the connecting rod.
