Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of resource reduction and high cost faced by copper alloys in the prior art, as well as the limited use of some copper alloy substitute materials in the prior art, and provide a high-zinc-aluminum base alloy with wear resistance. Bearing solid cage material, this material can completely replace copper alloy, and has a better use effect than copper alloy, fully improves the wear resistance of existing materials and reduces the friction coefficient, and greatly reduces the cost of use

Embodiment 1

[0024] In this embodiment, the following components by weight are used: aluminum: 81%; zinc: 17%; copper: 1.7%; manganese: 0.3%.

[0025] Each component of above-mentioned proportioning is processed by following process:

[0026] 1. Ingredients: that is, the raw materials (alloy elements) of each component of the above ratio are weighed in proportion for use;

[0027] 2. Melting: Add all the weighed raw materials (raw materials that have been baked without moisture) into the crucible, heat and melt, then refine, and finally pour the required mold;

[0028] 3. The cooled castings can be processed and used according to the drawings after stress relief treatment.

[0029] 4. It can also be plastically processed into required profiles according to requirements.

[0030] The material after the above process is inspected, and the material inspection is the body sample inspection in the casting. The inspection mainly focuses on the following aspects: σb (strength limit), δ (thickne...

Embodiment 2

[0032] In this embodiment, the ratios of the components used are: aluminum: 82%; zinc: 15%; copper: 2.2%; manganese: 0.8%.

[0033] Each component of the above proportioning ratio is processed according to the processing technology in Example 1, and then inspected, the inspection method is as in Example 1, and the inspection results are: σb≥339.2Mpa; δ≥7.30%; HB≥81.9; density≤ 3.05; friction coefficient ≤0.1106.

Embodiment 3

[0035] In this embodiment, the proportions of the components used are: aluminum: 83%; zinc: 13%; copper: 3.5%; manganese: 0.5%.

[0036] Each component of the above proportioning ratio is processed according to the processing technology in Example 1, and then inspected, the inspection method is as in Example 1, and the inspection results are: σb≥339.3Mpa; δ≥7.11%; HB≥82.0; density≤ 3.06; friction coefficient ≤0.1018.

Abstract

The invention discloses a high-zinc aluminium base bearing entity retainer material with abrasion-resisting property, relating to an alloy material. The high-zinc aluminium base bearing entity retainer material comprises the following components in percentage by weight: 81%-85% of aluminium, 13%-17% of zinc, 1.7%-3.7% of copper and 0.3%-1.0% of manganese. The high-zinc aluminium base bearing entity retainer material can solve the problems of resource decrease and excessive cost confronted by a copper alloy in the prior art and use restriction of copper alloy substitute materials in the prior art. The high-zinc aluminium base bearing entity retainer material can completely substitute for the copper alloy and has proportion advantage, price advantage and using effect which are better than that of the copper alloy; and in addition, the invention sufficiently improves the abrasion resistance of the traditional materials and reduces the friction coefficient, greatly reduces the use cost, has high strength, toughness and abrasion resistance and can be used as a good substitute material of the copper alloy.

Description

technical field [0001] The invention designs an alloy material, in particular relates to a high zinc-aluminum base bearing entity cage material with wear resistance. technical background [0002] The traditional material copper alloy is the most used material for bearing solid cages at home and abroad, and a small amount of engineering plastics and bakelite are used as cages. Copper alloy has excellent wear resistance, magnificent color and people's usage habits for thousands of years, so copper alloy naturally becomes the main material of cage. However, with the decrease of copper alloy resources and the increase of cost, the cost of copper alloy cage has risen sharply, so the materials for bearing cages have been developed accordingly, but the existing materials are all in a certain series, a certain A large number of copper alloy cages are still used in a certain environment or under a specific condition. In the prior art, there is no cage material that can completely re...
