Abstract
The invention discloses a double crank rocker gear rack transmission device which comprises a first rack, a first medium gear, a first small gear, a first gear shaft, arc grooves, a rocker pin shaft, a rocker, a large gear shaft, a large gear, a second medium gear, a second small gear, a second gear shaft, a second rack, a long connecting rod, a connecting rod pin shaft, a short connecting rod, a first crank pin shaft, a first crank, a second crank, a second crank shaft and a first crank shaft. The first crank, the second crank, the short connecting rod, the long connecting rod, the rocker and the three fixed shafts which are the large gear shaft, the second crank shaft and the first crank shaft form a double crank rocker mechanism. The double crank rocker mechanism is combined with a gear rack mechanism, the high-speed reciprocating intermittent linear motion of a motor under unidirectional continuous rotation is achieved, and the intermittent time and displacement can be changed through the rod length of the double crank rocker mechanism and the length of the arc grooves in the gears. The double crank rocker gear rack transmission device is suitable for high-speed reciprocating movement conditions with time remaining and only needs motor driving.
Description
technical field [0001] The invention relates to a mechanical transmission device, in particular to a double crank rocker rack and pinion transmission device. Background technique [0002] Reciprocating backlash motion is traditionally solved by means of mechanism transmission, such as a cam mechanism. At present, there is still a solution by repeatedly switching the solenoid valve to drive the cylinder or driving the motor to rotate forward and backward. However, the back and forth movement of the cylinder and the forward and reverse rotation of the motor are not conducive to the life of the cylinder and the motor under high-speed requirements, and there are certain restrictions on the speed. Contents of the invention [0003] The purpose of the present invention is to provide a transmission device for high-speed reciprocating gap motion, which combines a double crank rocker mechanism and a rack and pinion mechanism to realize high-speed reciprocating gap linear motion und...
