Embodiment Construction

[0032] The present invention will be further described below through specific embodiments.

[0033] see Figure 1 to Figure 4 , a lightweight fractal gradient gear, comprising a gear body 10 and two plate bodies 20 , the two plate bodies 20 are fixed on both sides of the gear body 10 . The gear body 10 has a porous lightweight structure 11 and a ring gear. The ring gear is sheathed on the outer periphery of the porous lightweight structure 11 , and bolts can be used to securely socket the ring gear and the porous lightweight structure 11 . The central part of the porous lightweight structure 11 is provided with a shaft hole 19 for connecting a transmission shaft.

[0034] The porous lightweight structure 11 of the present invention at least includes a first-level gradient pore group, a second-level gradient pore group, and a third-level gradient pore group, etc., which are interleaved with each other. Among them, the gradient series of the first-level gradient hole group is...

Abstract

The invention discloses a lightweight fractal gradient gear. The lightweight fractal gradient gear comprises a gear body and is characterized by further comprising two plate bodies, wherein the platebodies are fixed to the two sides of the gear body; and the gear body is of a porous lightweight structure, wherein the porous lightweight structure at least is composed of a first-stage gradient holegroup, a second-stage gradient hole group and a third-stage gradient hole group which are constructed in a staggered mode. According to the lightweight fractal gradient gear, a honeycomb type multi-cell structure serves as a prototype, and gradient type, split type and multi-type design is carried out, so that the maximum lightweight of the gear is achieved, and manufacturing is convenient.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a lightweight fractal gradient gear. Background technique [0002] Gears, as the most widely used form of mechanical transmission today, are widely used in many fields such as transportation, manufacturing, and intelligent industries. Gear transmission is one of the most important transmission forms in mechanical transmission. Gear transmission has the following characteristics: high efficiency, compact structure, reliable operation, long life, stable transmission ratio, and high installation accuracy requirements. [0003] In the manufacturing process of the gear, the ring gear part often needs multiple complicated processing procedures due to its complex stress situation and harsh working environment to ensure the fatigue strength and life of the gear, but the part inside the ring gear is stressed. It is relatively fixed and balanced, so it can carry out various lightwei...
