Abstract

The invention relates to an automatic deep-groove-ball-bearing wear life testing machine. The automatic deep-groove-ball-bearing wear life testing machine comprises a frame, an axial pneumatic loadingdevice, a drive system, a motor seat, locking bolts, support feet, a motor, an oil lubricating system, a heating device, an industrial personal computer, a charge amplifier, a sensor, a loudspeaker and a data collecting and control system. The automatic deep-groove-ball-bearing wear life testing machine has the advantages that the machine is adjustable in rotation speed and load and especially applicable to the vibration measuring and wear life testing of miniature and small deep groove ball bearings; many bearing vibration parameters (such as low-frequency, medium-frequency, high-frequency and direct-frequency effective values, peak values, peak value factors and pulse number) can be measured, a vibration threshold can be set, and after the fact that a bearing reaches the wear life is determined when the measured vibration value exceeds the set vibration threshold, the wear life testing machine automatically shuts down to guarantee safety.

Description

technical field [0001] The invention relates to an automatic deep groove ball bearing abrasion life testing machine, which belongs to the field of mechanical design and manufacture. Background technique [0002] Deep groove ball bearing is a kind of bearing product widely used in industry. It is composed of outer ring, inner ring, rolling elements and cage. It has good starting performance and load capacity; it is widely used in automobiles, motors, construction machinery and other fields. Low vibration and ultra-quiet bearings have gradually become the trend of the market. Deep groove ball bearings used in air conditioners, refrigerators, washing machines and other equipment should maintain low vibration and low noise for a long time to avoid causing discomfort to the staff in the working environment. How to measure the time for bearings to maintain low vibration and low noise has become an important topic in the bearing industry. Since the bearings used in these occasion...
