Abstract

The invention discloses a transmission speed change device, which comprises a reciprocating gear, a right-shift half gear, a left-shift half gear, and an input gear. The input gear is meshed with a right-shift input gear; the right-shift input gear and the right-shift half gear are fixed on a right-shift input shaft; the right-shift half gear is meshed with the reciprocating gear; the reciprocating gear is meshed with the left-shift half gear; the left-shift half gear and a left-shift input gear are fixed on a left-shift input shaft; the left-shift input gear is meshed with an idler wheel; and the idler wheel is meshed with the input gear. The right-shift half gear and the left-shift half gear are same in size, have a toothed radian of 180 DEG, have a phase difference of 180 DEG and are not simultaneously meshed with the reciprocating gear; the right-shift input gear and the left-shift input gear are same in type; and the input gear and the idle wheel are same in type. The transmission speed change device has the characteristics of stable operation, constant speed, uniform load and precise transmission, and is applicable to reciprocating movement of various machines.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a reciprocating linear motion transmission mechanism used in planers, robots, electric sewing machine heads and the like. Background technique [0002] Reciprocating linear motion has a wide range of applications in national production, such as the feed motion and cutting motion of various processing machine tools, reciprocating electric tools, punching machines in mold sheet metal, etc. At present, the mechanisms that realize reciprocating motion mainly include: crank slider mechanism or guide rod mechanism, cam mechanism, linear motor, two-way screw, etc. in the planar linkage mechanism. The connecting rod mechanism is widely used because of its simple structure and easy processing, but its transmission route is long, and it is easy to generate large error accumulation; Due to the large dynamic load, it is not suitable for high-speed movement. [0003] Although the dyna...
