Problems solved by technology

[0003] In the current market, most eccentric shafts have a simple structure design, and there is only one eccentric shaft body, so it can only push one piston to reciprocate, which cannot meet the actual use needs

Abstract

The invention discloses an eccentric shaft. The eccentric shaft comprises a first shaft piece and a second shaft piece, and a first eccentric wheel and a second eccentric wheel arranged between the first shaft piece and the second shaft piece and connected with each other; the first eccentric wheel is fixedly connected with the first shaft piece; the second eccentric wheel is fixedly connected with the second shaft piece; a shaft groove is formed in the first shaft piece; a gear groove is formed in the second shaft piece; the axes of the first shaft piece and the second shaft piece are a coaxial line; a first axis of the first eccentric wheel and a second axis of the second eccentric wheel are not the same axis; the first axis and the second axis have the same distance from the coaxial line; and the first axis, the second axis and the coaxial line are positioned on the same plane. The eccentric shaft is reasonable in structural design and compact in total layout, is provided with two eccentric shaft bodies, can own more stable and precise eccentric angles, can keep equipment stable, and has such characteristics as low vibration and low pressure fluctuation.

Description

technical field [0001] The invention relates to the technical field of shaft structures, in particular to an eccentric shaft. Background technique [0002] At present, the mechanical structure that controls linear motion or rotary motion often adopts a separate structure, that is, the two types of motion are controlled by corresponding connection mechanisms, which increases the complexity of the structure. The structure of the eccentric shaft can solve the above problems well. The eccentric shaft is an important part of equipment such as pistons and transmission structures. However, the center of the eccentric shaft in the prior art is not at the center of the axis. The general shaft can only drive The workpiece rotates by itself, but the eccentric shaft can not only transmit the rotation, but also the revolution. The structural feature of the eccentric shaft is that it has two axes that are parallel but not coincident. [0003] In the current market, most eccentric shafts...
