Problems solved by technology

The second is that the response time to the speed change or even the direction change of the input speed should be short, which requires the moment of inertia of the transmission disc to be small; and the radius of rotation on the disc is r i mass m i The moment of inertia J of the microunit i i =m i r i 2 , that is, the greater the mass of the disc, the greater the moment of inertia; but the density of the steel material is high, resulting in a heavy drive disc and a large moment of inertia
[0007] The above-mentioned existing lightweight technical solutions for steel transmission discs are difficult to take into account both weight reduction and excellent transmission performance

Embodiment 1

[0036] Material: aluminum alloy AA6061 powder (average particle size 32 microns, volume ratio 85%), strengthening phase B 4 C powder (average particle size 14 microns, volume ratio 15%).

[0037] Process, using powder hot pressing method (HIP or HVP method): (1) AA6061 powder and B 4 C powder mixing (Mixing and Blending). Wherein the aluminum alloy powder can be the aluminum alloy powder made by the existing aluminum alloy, or the powder of various components in the aluminum alloy can be mixed with the strengthening phase powder according to the proportion in the aluminum alloy base material. The aluminum alloy substrate is formed during the sintering process of the AMC. The same is true for the formation of aluminum alloy substrates in the following examples. (2) Put the homogeneously mixed AMC mixture into a can-type metal mold (Canning) that can be closed and has an exhaust pipe, and degas (Degassing / Evacuation). (3) Heat the pumped pot mold with AMC mixture to the spec...

Embodiment 2

[0039] Material: aluminum alloy AA6061 powder (average particle size 32 microns, volume ratio 75%), strengthening phase B 4 C powder (average particle size 12 microns, volume ratio 25%).

[0040] Process, using powder isostatic pressing sintering method (CIP method): (1) AA6061 powder and B 4 C powder mixing (Mixing and Blending). (2) Put the uniformly mixed AMC mixture into a rubber mold with an air outlet pipe, pressurize the rubber mold with the AMC mixture at room temperature, and then remove the outer rubber mold to obtain AMC powder ingot (Cold Isostatic Processing) . (3) Heat the AMC powder ingot in a vacuum furnace to the specified AMC sintering temperature, 550°C, to become an AMC ingot, and finally obtain the aluminum matrix composite material B.

Embodiment 3

[0042] Materials: aluminum alloy AA6082 aluminum ingot (average particle size 60 microns, volume ratio 95%), strengthening phase SiC powder (average particle size 30 microns).

[0043] The process uses the spray molding method (Spray method): (1) After melting the AA6082 ingot, it is sprayed downward through the powder injection device, and at the same time, the SiC powder is sprayed into the aluminum alloy powder, and the aluminum alloy powder and SiC powder are controlled. The volume ratios are 95% and 5%. (2) The mixed powder is deposited and solidified in the collecting device below, and the aluminum matrix composite material C is finally obtained.

Abstract

The invention discloses a light-weight aluminum matrix composite transmission disc for a chain and a belt transmission device. The weight of a transmission disc is greatly reduced, so that the whole chain and a belt transmission device are lightened. The specific rigidity of the aluminum-based composite material is not less than 30GPa / g / cm < 3 > and is higher than that of the existing metal, so that the chain and the belt transmission device which are provided with the AMC lightweight transmission disc can keep good transmission performance.

Description

technical field [0001] The invention relates to the technical field of chain and belt transmission, and more specifically relates to a lightweight aluminum-based composite material transmission disc used in chain and belt transmission devices, especially high-performance chain and belt transmission devices with high requirements for light weight. Background technique [0002] Chain and belt drives are commonly used mechanical transmissions for the transmission and speed change of non-coaxial rotating power with distance. They have a common feature in structure: at least two transmission discs are combined by a chain ring or a belt ring, and the transmission disc is composed of an inner disc and an outer drive ring; there is a shaft hole in the center of the inner disc, which is used to install the rotary power input or output. axis. For chain transmission, the outer transmission ring is a gear ring structure, so that it is engaged with the chain for transmission. This kind ...
