Title:
MACHINE PROVIDED WITH RECIPROCATING SLIDER CRANK MECHANISM AND METHOD FOR DESIGNING MACHINE PROVIDED WITH RECIPROCATING SLIDER CRANK MECHANISM
Document Type and Number:
WIPO Patent Application WO/2017/141458
Kind Code:
A1
Abstract:
Provided is a machine provided with a reciprocating slider crank mechanism in which the shaft center of a crank shaft, the shaft center of a first balancer shaft, and the shaft center of a second balancer shaft are not disposed within the same plane, wherein vibration is highly suppressed. This machine is provided with the reciprocating slider crank mechanism configured to satisfy the following formulas. UCr=UP×0.5 αCr=180° UB(Fr)={U1B(Fr) 2+U2B(Fr) 2}1/2 U1B(Fr)=-UP×0.5×{Lx´B(Rr)/(Lx´B(Rr)-Lx´B(Fr))} U2B(Fr)=-UP×0.5×{Ly´B/(Lx´B(Rr)-Lx´B(Fr))} αB(Fr)=180°-arctan(U2B(Fr)/U1B(Fr)) UB(Rr)={U1B(Rr) 2+U2B(Rr) 2}1/2 U1B(Rr)=-UP×0.5×{Lx´B(Fr)/(Lx´B(Fr)-Lx´B(Rr))} U2B(Rr)=-U2B(Fr) αB(Rr)=180°-arctan(U2B(Rr)/U1B(Rr))
