ZHUKOVSKY REVERSING CIRCLE-TRACING MECHANISM

Click to enlargeClick to enlarge Description

The lengths of the links comply with the conditions: P͞A=A͞Q=Q͞B=B͞P=m, O͞A=O͞B=n, O͞C=O͞D=a, C͞P=D͞Q=r and m²-n²=a²-r²=const. Figure AQBP is a rhombus and figure AOBP is a rhomboid linkage. When link 1 rotates about fixed axis C, point P describes circle p-p of radius r, and point Q describes circle q-q of the same radius r. Therefore, by adding link 2, shown by dash lines, the mechanism can be made to transmit rotation with a mean transmission ratio i_m between links 1 and 2 per full revolution equal to i_m=ω₁/ω₂=-1, i.e. link 2 rotates in the opposite direction to link 1.
