Correcting method for oil film thickness of mill roll bearing
专利汇可以提供Correcting method for oil film thickness of mill roll bearing专利检索，专利查询，专利分析的服务。并且PURPOSE:To correct the oil film thickness to the optimum condition, by operating the comparison for obtaining the deviation of the actual oil film thickness from the theoretically optimum oil film thickness corresponding to the circumferential speed of the roll, and by correcting the oil film thickness with this deviation value after being multiplied by a factor specified according to the rolling load. CONSTITUTION:The signal P of the rolling load detected by the rolling load detector is inputted to the rolling load function generator 1 which then selects the load factor K corresponding to the rolling load P and inputs this factor K to the multiplier 2. The backup roll's circumferential speed V detected by the speed detector is inputted to the oil film thickness/roll speed function generator 3 and also inputted to the hysteresis correction function generator 6 through the acceleration/deceleration changeover switch 5. The oil film thickness/roll speed function generator 3 selects the theoretical oil film thickness (t) corresponding to the roll's circumferential speed V, and sends it to the comparison operator 4; the hysteresis correction function generator 6 operates the deviation DELTAt from the reference theoretical oil film thickness (t) corresponding to the roll speed at accelerating or decelerating the roll speed. This signal DELTAt is sent to the comparison operator 4 which compares (t) with DELTAt; at accelerating the roll speed, the signal t+DELTAt, and at decelerating the roll peed, the signal t-DELTAt, are sent to the multiplier 2, and are multiplied by the factor K to be decided correspondingly to the rolling load P; hereby, the corrected oil film thickness is decided. This corrected oil film thickness is sent to the roll gap adjusting device.，下面是Correcting method for oil film thickness of mill roll bearing专利的具体信息内容。
