針對目前軸承廠家對軸承外圈的檢驗仍采用人工檢驗,勞動強(qiáng)度大,效率低,容易引入人為
誤差,影響產(chǎn)品出廠質(zhì)量的問題,研制了一種用于軸承外圈幾何參數(shù)的自動檢測與分選系統(tǒng). 該系統(tǒng)采用了差動電感式傳感器對軸承外圈幾何參數(shù)進(jìn)行測量,利用可編程控制器進(jìn)行分選的測控,減小測量誤差.

Abstract : Nowadays , most bearing manufacturers adopt still the manual examination of bearing outer race. Such kind of examination mean heavy labor intensity , low productivity , man2made error , and uncertainty of product quality. Therefore , a system of automatic examination and grading of geomet rical parameters of bearing outer races is developed. In this system , a differential inductance sensor is employed for measuring the geomet ric
parameters of outer race and a programmable cont roller is used to cont rol the process of grading so that the mea2 suring error can be reduced.
Key words : bearings outer race ; geomet rical parameter ; examination ; data acquisition ; programmable con2 t roller
