摘要
Abstract
After a certain type of relay is stored in a low-temperature environment of-55 ℃,there exists a problem that the release voltage decreases significantly or even fails.Through problem investigation,a thermal-structural coupling simulation model is used to quantitatively analyze the deformation of the shaft-hole of the relay at low temperature.It is found that the deformation of the hole at low temperature is about 3 times that of the shaft,and the burrs exist in the holes of the failed products.The analysis shows that the deformation of parts will increase the shaft-hole pressure,leading to a simultaneous increase in friction,which ultimately reduces the product release voltage.By optimizing the minimum shaft-hole fit clearance of 3 batches of products from 0.01 mm to 0.02 mm and strengthening the control of burrs in the holes,the product qualification rate increased from 85％to over 98％verifying the effectiveness of the optimization scheme,which provides a new design direction for relay tolerance optimization and burr control in the shaft-hole design of drive components.关键词
