Abstract

A novel movement mechanism with planetary gear chain for the conversions between rotation and linear reciprocation and from rotation to elliptical movement is composed of sun gear fixed to axle, planetary gear which as a diameter the equal to the radius of sun gear and can revolve around sun gear while rotate, satellite axle revolving around planetary gear, crank gear, cantilever, supporter and accessories. When the resistance arm of cantilever is equal to that of crank, the satellite axle does linear reciprocation with its stroke 4 times greater than that of resistance arm. If they are no equal to each other, the satellite axle does elliptical movement with its stroke 2-6 times greater than that of resistance arm.

Description

technical field

[0001] The invention is a super-large stroke motion conversion mechanism, which is a mechanism for mutual conversion between rotation and linear reciprocating motion, and can also convert rotation into elliptical motion, and is suitable for various machines with large strokes. Background technique

[0002] At present, the motion conversion mechanism includes a crank-link mechanism, a crankshaft-link mechanism, and a cam, etc., and their strokes are small, and the rectilinear reciprocating motion of a long distance is usually reversed by a motor or other methods, and the efficiency is very low. Invention content:

[0003] In order to solve the above problems, the present invention provides a high-efficiency ultra-large stroke motion conversion mechanism—a new type of motion mechanism of planetary gear train.

[0004] The technical scheme of the present invention is: in the planetary gear train, adopt specific gear ratio, and the necessary association mode of...
