The characteristics of motion about cam link mechanism was explained according to rise and two stages of return:
1) rise
Requiring pushing hands to keep attitude only to do motion of translation in the rise goods straight line is pushed, is 0 so pushing hands reaches the cireular frequency of second belt wheel 11 fixed with it.
Shown in figure 10, the condition that planetary wheel mechanism produces linear reciprocating motion is:
Figure 154720DEST_PATH_IMAGE001
Wherein and
Figure 683026DEST_PATH_IMAGE004
is respectively pinion carrier 2 radiuses and cireular frequency thereof,
Figure 497398DEST_PATH_IMAGE005
and be respectively satellite gear connecting rod 7 length and cireular frequency thereof.
With satellite gear connecting rod 7 is reference system, and second largest belt wheel 11 with respect to the acceleration/accel
Figure 852473DEST_PATH_IMAGE007
of connecting rod 7 is:
Figure 51373DEST_PATH_IMAGE008
The number of teeth according to first belt wheel 9 is 1/2 of second belt wheel 11, can know that first belt wheel, 9 cireular frequencys relative and connecting rod 7 are:
Figure 323403DEST_PATH_IMAGE010
With frame 1 is reference system, and the absolute angle speed of first belt wheel 9 is:
