Linear transmission system with a lubrication device

A linear transmission system with a lubrication device comprising:

• an elongated shaft being defined with a rolling groove in an outer surface thereof;
• a movable body being disposed on the elongated shaft and allowed to move back and forth along the elongated shaft, the movable body being defined with a rolling groove opposite the rolling groove of the elongated shaft, the rolling groove of the elongated shaft cooperating with the rolling groove of the movable body to define a loaded path;
• plural rolling elements being disposed in the loaded path;
• a circulating assembly being disposed on the movable body and defined with a circulating passage for circulation of the rolling elements;
• a lubrication device being disposed on the movable body and defined with an accommodation trough and an oil hole, in the accommodation trough being disposed a guiding assembly, the guiding assembly cooperating with the accommodation trough to define an oil storage space for accommodation of lubricating grease, the oil storage space being in communication with the oil hole;
• and
• a power module being connected to the guiding assembly to drive the guiding assembly at regular intervals;
• wherein the power module is disposed in the lubrication device and includes a power supply, a controller and a motor, the power supply supplies power to the controller, and the controller drives the motor at regular intervals.
