Abstract

A non-circular gear type uniform-speed linear reciprocating mechanism features that the pitch curves of the drive and driven gears in the non-circular gear driving set are designed according to predefined ideal output movement curve, so resulting in true uniform speed.

Description

The noncircular gear type is linear reciprocating motion mechanism at the uniform velocity
What technical field the present invention relates to is at the uniform velocity linear reciprocating motion mechanism of a kind of noncircular gear type, the especially wherein shape of the pitch curve of noncircular gear.
The noncircular gear type that background technique is existing to be used for exporting linear reciprocating motion at the uniform velocity is linear reciprocating motion mechanism at the uniform velocity, and noncircular gear has three kinds of forms: elliptic gear+deceleration cylindrical gears, oval gear and eccentric circle conjugation noncircular gear.For example on wool spinning high speed roving machine, be to realize at the uniform velocity toward the motion of complex line guide, the eccentric circle conjugation noncircular gear type that is provided with an eccentricity and is 0.34 (e=0.34) is linear reciprocating motion mechanism at the uniform velocity.The characteristics of motion that this three exports after suitably choosing eccentricity is quite similar, all is approximate linear reciprocating motion at the uniform velocity, because they all only can regulate its eccentricity, is out of the question at all so will export desirable velocity curve.
Summary of the invention is at above-mentioned defective, technical problem to be solved by this invention be exactly to make the noncircular gear type at the uniform velocity the movement velocity in the most of the time, exported of linear reciprocating motion mechanism reach at the uniform velocity, thereby at the uniform velocity linear reciprocating motion mechanism of a kind of noncircular gear type that is used to export linear reciprocating motion at the uniform velocity is provided.
Noncircular gear type provided by the invention is linear reciprocating motion mechanism at the uniform velocity, combine by noncircular gear transmission and sine generator scotch yoke, wherein the gear shaft 3 of the driven gear 2 in the gyration center of the crank in the sine generator scotch yoke 4 and the noncircular gear transmission is on same axis, and fixing installation angle is arranged between the driven gear in crank in the sine generator scotch yoke and the noncircular gear transmission, said sine generator scotch yoke comprises the slidercrank mechanism of the near sinusoidal mechanism that connecting rod and crank length ratio are bigger, in said noncircular gear transmission:
1. the pitch curve of driving gear 1 is formed by the mirror point smooth connection that is symmetry axis with 0 ° of line wherein of the point on the utmost point in the same sequence number in following table footpath and the determined polar coordinates of polar angle and they:
