Problems solved by technology
[0002] All rotating electrical machines need bearings to support the rotating parts. Bearings are the core components of the motor, and their operating life and reliability determine the life and reliability of the motor. In the life test method of bearings, actual products are often used for 1: 1 life test, this method takes a long time, and life and reliability data cannot be obtained in a short period of time

Embodiment Construction
[0026] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.
[0027] Such as Figure 1 to Figure 11 A bearing life acceleration test device shown includes a tooling vertical plate 1, a motor, a sensor rotor 11, and a load plate 7; the motor is fixed on the tooling vertical plate 1, and the sensor rotor 11 passes through the motor and is rotated by the motor. The front and rear ends of the rotor 11 are fixed with a load plate 7, and the bearing 14 is installed on the sensor rotor 11 for testing. The installation position of the bearing 14 on the sensor rotor 11 is between the load plate 7 and the sensor rotor 11 and / or at the end of the motor.
[0028] The motor is made up of a motor stator 34 and a motor rotor 35 , the sensor rotor 11 is fixed on the motor rotor 35 , and the motor stator 34 is fixed on the frock stand 1 around the motor rotor 35 .
[0029] The load plate 7 is that two flat p...

The invention provides a bearing life acceleration test device which comprises a tool vertical plate, a motor, a sensor rotor and load plates. The motor is fixed on the tool vertical plate. The sensorrotor penetrates through the motor and is driven by the motor to rotate, the load plates are fixed at the front end and the rear end of the sensor rotor, the bearing is installed on the sensor rotorfor testing, and the installation position of the bearing on the sensor rotor is located between the load plates and the sensor rotor and / or at the end of the motor. The actual operation conditions ofthe motor are combined, including the rotating speed, the axial load, the radial load and the life acceleration factor, the actual operation state of the motor is simulated, and the life test verification and reliability verification of the bearing can be accelerated. The structure is simple, the design is novel, and the bearing life test time can be greatly shortened.
Description
technical field [0001] The invention relates to a bearing life accelerated test device. Background technique [0002] All rotating electrical machines need bearings to support the rotating parts. Bearings are the core components of the motor, and their operating life and reliability determine the life and reliability of the motor. In the life test method of bearings, actual products are often used for 1: 1, this method takes a long time, and the life and reliability data cannot be obtained in a short period of time. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a bearing life accelerated test device, which combines the actual operating conditions of the motor, including the speed, axial load, radial load and life acceleration factor, to simulate the motor The actual operating status of the bearing can be accelerated to complete the life test verification and reliability verification of the bearing.
