摘要:针对目前市场上密封轴承气密性检测精度低、抗干扰能力不强、效率低下等缺点,结合轴承实践生产情况,设计了一种新型密封轴承气密性检测仪器。该仪器利用轴承阻隔气流,使进气端达到一定气压值,然后观察气压表数值变化从而判断轴承的气密性。该仪器检测精度高,结构简单,检测型号多,并且在生产检测过程中检测直观、可操作性强、检测成本低,完全满足实际生产需求。

Abstract:Aiming at the defect of sealed bearing on the current market, such as low detecting precision, poor anti-interference ability, low efficiency. Combining with the realistic production, a kind of air tightness detection instrument for new sealed bearing is designed. This instrument uses the bearing to block the airflow, so that the intake side reaches a certain value of air pressure, and then observe the change of the barometer to determine the air tightness of the bearing. This instrument has the characteristics of high detection precision, simple structure and more detection types, and it shows visual inspection, strong operability and low cost in the process of production inspection, which fully satisfied the requirement of actual production.
Key words:sealed bearing;air tightness;detection
