Abstract

A linear transmission system with a lubrication device comprises a transmission member, a lubrication device and a moving member. The lubrication device is disposed at an end of a linear moving direction of the transmission member. The moving member performs a linear displacement on the transmission member. When the moving member moves and contacts the lubrication device, the lubricant in an oil tank of the lubrication device will be guided to the moving member, so as to fill the lubricant without using additional power supply, which is energy saving. Moreover, the oil tank of the lubrication device is independently disposed on the transmission member, so that the user can observe the lubricant easily. Thereby, such a device is simple to use, and is convenient to assemble and disassemble.
