Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearing ring surface strengthening and modification equipment under high and low temperature working conditions, in particular to a temperature-assisted bearing ring ultrasonic strengthening modification device. BACKGROUND

[0002] In the field of mechanical manufacturing, the strengthening treatment of bearing rings has always been a key link to improve the performance of bearings. As an advanced surface strengthening technology, ultrasonic strengthening modification can significantly improve the surface hardness, residual stress distribution and fatigue life of bearing rings. However, the existing ultrasonic shot blasting equipment has some obvious limitations when applied to bearing ring processing.

[0003] Firstly, most traditional ultrasonic shot blasting equipment can only be processed at room temperature. In actual use, bearing rings often face complex working conditions, including high temperature, low temperature and alternating high and low temperature environments. Ultrasonic shot blasting treatment at room temperature cannot meet the strengthening needs under these special working conditions. For example, in a high temperature environment, the material properties of the bearing ring will change, and the surface layer after room temperature strengthening may lose part of the strengthening effect due to material thermal expansion and thermal relaxation at high temperature; while in a low temperature environment, the material becomes more brittle, and the surface layer after room temperature strengthening may not be able to effectively resist the impact and wear under low temperature.

[0004] Secondly, the existing ultrasonic shot blasting equipment has the problem of low processing efficiency when processing the inner and outer rings of the bearing ring. This is because traditional equipment usually adopts a single shot blasting path and fixed shot blasting parameters, which cannot be flexibly adjusted according to the different shapes and sizes of the inner and outer rings. In the processing of large or complex shaped bearing rings, this fixed processing mode will lead to uneven shot blasting, insufficient strengthening in some areas, and excessive strengthening in other areas, affecting the overall performance of the bearing.

[0005] In addition, the existing ultrasonic shot blasting equipment has a big defect in temperature control. On the one hand, the equipment lacks an effective temperature regulation system, which cannot monitor and adjust the temperature of the processing environment in real time during processing, making it difficult to ensure the stability and consistency of the processing process; on the other hand, even if some equipment has certain temperature control function, its temperature control range is limited, which cannot meet the processing requirements under complex working conditions such as alternating high and low temperature, resulting in the inability to effectively implement ultrasonic shot blasting strengthening process under special working conditions.

[0006] These deficiencies in the prior art are mainly due to the single design concept and technical architecture of traditional ultrasonic shot blasting equipment, which fails to fully consider the use requirements of bearing rings under complex working conditions and the characteristic differences of different processing objects.

[0007] Therefore, developing a device capable of efficiently and uniformly ultrasonic strengthening modification processing of the inner and outer rings of the bearing ring under high temperature, low temperature or alternating high and low temperature working conditions has important significance for improving the performance and reliability of the bearing ring and meeting the demand of the modern mechanical manufacturing field for high-performance bearings.
