Abstract
A lubrication monitoring system for monitoring the lubricative state of two relatively movable elements of a linear transmission device includes a contact resistance capturing device and a processing unit. The contact resistance capturing device for detecting the contact resistance between the two elements and converting it into a corresponding value. A maximum delay time and a threshold value are preset in the processing unit. A period of time during which the linear transmission device starts to run and then the corresponding value reaches the threshold value defines a delay time. If the specific value of the delay time to the maximum delay time is larger than or equal to a predetermined specific one, it will be judged that the lubrication needs resupply. Therefore, monitoring the lubricative state as the linear transmission device is accelerated can get correct lubricative state to enable correct lubrication resupply.
