Bearing base aging treatment method and device capable of realizing temperature-force coupling loading

Abstract

The invention relates to a bearing matrix aging treatment method and device. The method is characterized by comprising the following steps: 1) preparing a bearing matrix aging treatment device capable of implementing temperature-force coupled loading, wherein the device comprises a force coupled loading device and a temperature control box provided with a heating furnace, and the force coupled loading device comprises an upper cover, a locking bolt, a cambered pressing block, a slider, a shell, a bevel gear wheel, a base and a bevel pinion; 2) flatly putting the bearing matrix on the outer side of the cambered pressing block; rotating the bevel pinion, limiting the radial movement of the bearing matrix and enabling the bearing matrix to bear the radial force; 3) putting into the temperature control box provided with a heating furnace, regulating the furnace mild heating and holding time, and carrying out temperature-force coupled loading aging treatment on the bearing matrix; and 4) after finishing the treatment, taking out the bearing matrix. The method can promote the unstable structure in the bearing matrix to change, thereby enhancing the stability of the bearing matrix structure and ensuring the precision stability and service life in the bearing service process.

Description

technical field [0001] The invention relates to a bearing matrix aging treatment method and a device thereof, in particular to a bearing matrix aging treatment method and a device thereof capable of realizing temperature-force coupled loading. Background technique [0002] Bearings are the key precision parts of mechanical equipment, and their precision directly affects the working precision and reliability of the main engine. The matrix structure of the bearing after conventional heat treatment is retained austenite, tempered martensite and a small amount of carbides, and the retained austenite and tempered martensite are both unstable structures. However, the temperature and load during the service process of the bearing will promote the transformation of the unstable structure of the matrix, cause dimensional changes, lead to the gradual loss of bearing precision and eventually lose it, and affect the service life of the bearing and the reliability of the main engine.
