According to the bearing ball air floatation rotation surface defect detection device, a rotary table support is fixedly arranged on a base plate; the rotary table support is provided with a vertical rotary table; the table surface of the rotary table is fixedly connected with a microscope mechanism; a gas storage shell pedestal is horizontally arranged on the base plate and below the microscope mechanism; a gas storage shell is arranged on the gas storage shell pedestal; the top end of the gas storage shell is provided with an upper cover; the gas storage shell pedestal is provided with an air inlet passage; the upper cover is provided with an air nozzle; the side wall of the air nozzle is provided with an air outlet groove; a bearing ball is placed on the air nozzle; a gas storage chamber is arranged in the gas storage shell; the upper end and the lower end of the gas storage chamber are communicated with the air nozzle and the air inlet passage respectively; and a pneumatic rotating joint is arranged in the air inlet passage and is communicated with the air inlet passage. The bearing ball air floatation rotation surface defect detection device is used for detecting bearing ball surface defects.

Description

technical field The invention relates to a device for detecting defects on the air-floating rotating surface of a bearing ball. Background technique Rolling bearings are essential and key basic parts of mechanical systems, which have an important impact on their running accuracy, ultimate performance, reliability and other aspects. Ball bearings are the most common type of rolling bearings and are used in a wide variety of mechanical systems. The running accuracy, service life and limit index of the ball bearing largely depend on its core - the bearing ball. The surface defects of bearing balls will not only reduce the wear resistance and lead to a significant reduction in strength, but also often cause local stress concentration and become the origin of fracture, which can easily lead to damage to parts and seriously affect the running accuracy, fatigue life and reliability. According to statistics, 60% of bearing failures are due to cracks and cracks caused by surface d...
