9. according to claim 1 to a kind of drive method of Eccentric Gear-drive device described in 8 any one claims,
Be characterized in that: linear reciprocating motion can be changed into continuous rotation movement by this method, be included the following steps:
Step 1: cabinet mounting plate is fixed on datum clamp face, the both ends installation of linear motion axis can provide reciprocal straight
The driving mechanism of line movement, the driving force that driving mechanism is applied to linear motion axis both ends is contrary, can be according to power source
One end of linear motion axis applies driving force；
Step 2: being applied to the instantaneous starting torque that eccentrically weighted shaft can be such that it rotates；
Step 3: uniformly applying periodic linear reciprocating motion power to linear motion axis by driving device；
4th step；Linear motion axis band movable gear shaft and ring gear engaged transmission, so that the axis of gear shaft is around eccentrically weighted shaft
Axis rotation, exported to transmit torque on eccentrically weighted shaft, in conjunction with the instantaneous starting torque that applies on eccentrically weighted shaft and
The inertia of flywheel is to obtain the torque for rotating eccentrically weighted shaft；
Step 5: eccentrically weighted shaft drives flywheel to do continuous rotation movement, that is, realizes and linear reciprocating motion is changed into continuous rotation
Transhipment is dynamic.
10. according to claim 1 to a kind of drive method of Eccentric Gear-drive device described in 8 any one claims,
It is characterized by: this method, which can move continuous rotation, is changed into linear reciprocating motion, include the following steps:
Step 1: cabinet mounting plate is fixed on datum clamp face, installation can provide the drive of turning moment on eccentrically weighted shaft
Motivation structure, eccentrically weighted shaft can main story also invert, flywheel can be cancelled；
Step 2: eccentrically weighted shaft transmits torque to gear shaft, gear shaft and ring gear engaged transmission make the bias of gear shaft
Spindle nose moves up and down, and the eccentric spindle nose of gear shaft passes through gear shaft rolling bearing again and linear motion axis is driven to do reciprocating linear fortune
It is dynamic；
Step 3: linear motion axis connection execution unit outputting reciprocating linear movement, can be realized and turn continuous rotary motion
Turn to the function of linear reciprocating motion.
