Problems solved by technology

When the rolling bearing is working, the bearing heats up and wears due to sliding friction. Especially under high-temperature operating conditions, the action of inertial centrifugal force intensifies the friction, wear and heat. Low efficiency and short life
In addition, there are also deficiencies in the structural setting of the outer ring of the bearing. When performing relative motion and bearing certain radial loads and axial loads, the requirements for the strength of the inner and outer rings of the bearing and the firmness of the force point are relatively high.
At the same time, the alloy materials currently used to manufacture bearings cannot achieve self-lubrication, resulting in the need to add a lot of lubricating oil, which greatly increases the cost of use, which is not conducive to the long-term development of the enterprise and needs to be improved

Embodiment 1

[0063] An alloy material for manufacturing the outer ring of a deep groove ball bearing, characterized in that it includes the following components according to the weight ratio:

[0064] Iron content at 73%;

[0065] Manganese content at 5%;

[0066] Copper content is 3%;

[0067] Magnesium content at 5%;

[0068] Aluminum content is 4.2%;

[0069] Cadmium content is 0.3%;

[0070] Lithium content is 6.5%;

[0071] The content of nano graphite is 3%.

[0072] In the present invention, with the rational allocation and increase of manganese content, magnesium content, aluminum content and lithium content, the structural strength, oxidation resistance and corrosion resistance of the overall bearing outer ring are significantly improved, and the service life is prolonged. In addition, the content of nano graphite in the present invention is 3%, so that the alloy has a certain self-lubricating effect, increases lubricity, reduces the demand for lubricating oil, and obviously...

Embodiment 2

[0074] An alloy material for manufacturing the outer ring of a deep groove ball bearing, characterized in that it includes the following components according to the weight ratio:

[0075] Iron content at 78%;

[0076] Manganese content at 7%;

[0077] Copper content is 4.7%;

[0078] Magnesium content at 5%;

[0079] Aluminum content is 0.5%;

[0080] Cadmium content is 1.3%;

[0081] Lithium content at 1.5%;

[0082] The content of nano graphite is 2%.

[0083]In the present invention, with the rational configuration of iron content, manganese content, magnesium content, aluminum content and lithium content, the structural strength, oxidation resistance and corrosion resistance of the overall bearing outer ring are improved, and the service life is prolonged. In addition, the content of nano graphite in the present invention is 2%, so that the alloy has a certain self-lubricating effect, increases lubricity, reduces the demand for lubricating oil, and reduces the number...

Embodiment 3

[0085] An alloy material for manufacturing the outer ring of a deep groove ball bearing, characterized in that it includes the following components according to the weight ratio:

[0086] Iron content at 80%;

[0087] Manganese content at 5%;

[0088] Copper content is 4.7%;

[0089] Magnesium content at 6%;

[0090] Aluminum content is 0.5%;

[0091] Cadmium content is 1.3%;

[0092] Lithium content is 1%;

[0093] The content of nanometer graphite is 1.5%.

[0094] In the present invention, with the increase of iron content, the reduction of manganese content, magnesium content, aluminum content and lithium content, the oxidation resistance and corrosion resistance of the overall bearing outer ring are somewhat improved, and the service life is prolonged. In addition, the content of nano-graphite in the present invention is relatively low, so that the alloy has a certain self-lubricating effect, but a certain amount of lubricating oil needs to be added during use.

Abstract

The invention discloses a deep groove ball bearing outer ring, which comprises an outer ring body, wherein the outer end surface of the outer ring body is conical; an annular graphite layer is embedded in the inner surface of the outer ring body and is close to one end of the outer ring body with a larger outer diameter; slots are formed in two sides of the graphite layer; a graphite bar is embedded in the bottom of the slot. The invention further relates to an alloy material for manufacturing the deep groove ball bearing outer ring. The alloy material comprises the following material in percentage by weight: 60-80% of iron, 6-8% of manganese, 3-5% of copper, 3-5% of magnesium, 0.5-10% of aluminum, 0.3-2% of cadmium, 1-8% of lithium and 1.5-5% of nano graphite. According to the deep groove ball bearing outer ring, the structural strength and lubricating performance are improved; the product load is alleviated and the service life is prolonged.

Description

technical field [0001] The invention relates to an outer ring of a deep groove ball bearing, and also relates to an alloy material used for manufacturing the outer ring of a deep groove ball bearing. Background technique [0002] Rolling bearings are widely used important mechanical basic parts, and are widely used in various fields of national economy and national defense. When the rolling bearing is working, the bearing heats up and wears due to sliding friction. Especially under high-temperature operating conditions, the action of inertial centrifugal force intensifies the friction, wear and heat. Low efficiency and short life. In addition, there are also deficiencies in the structural setting of the outer ring of the bearing. When performing relative motion and bearing certain radial loads and axial loads, the requirements for the strength of the inner and outer rings of the bearing and the firmness of the force points are relatively high. At the same time, the alloy m...
