Abstract

The invention relates to the technical field of bearings, and particularly discloses a prediction device for a tapered roller bearing during configuration of pretightening force. The prediction device comprises a bearing tool, the bearing tool comprises a core shaft for mounting a bearing to be measured and a shell matching an outer ring of the bearing to be measured, the core shaft is provided with two bearing mounting stations, one end of the core shaft is connected with a locking nut, the other end of the core shaft is connected with a motor, a torque sensor is arranged between the core shaft and the motor, a temperature measuring hole is formed in the shell, and a temperature sensor is arranged on the temperature measuring hole. With the adoption of the structure, the detection device for the tapered roller bearing during configuration of pretightening force is provided, and is used for detecting the influence of factors such as mounting fit, rigidity of a shaft and the shell, temperature and the like on a pretightening load in practical application; the influence caused by the lubricating oil, the flow of the lubricating oil and the shaft system temperature rise in the bearing operation process and the coupling effect of the temperature rise and the pretightening load are further detected.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a predictive device when a tapered roller bearing is configured with a pretightening force. Background technique [0002] When tapered roller bearings are used as separate bearings in pairs in axles, they need to be preloaded axially. In the axle, the tapered roller bearing is mainly preloaded by the gasket and locked by the lock nut. The bearing supplier generally provides the bearing preload according to experience. For the face-to-face tapered roller bearing arrangement or the back-to-back tapered roller bearing arrangement, a test fixture is designed, and the test methods for various factors affecting the preload of the bearing arrangement are proposed. [0003] Bearing preload is an important parameter to determine bearing capacity and running quality. The preload of tapered roller bearings affects the stiffness, life and reliability of the bearing system. When the actua...
