Abstract: A method for determining timing of oil filling for a linear motion actuator can determine whether the oil film in a specific time period is sufficient, falling or insufficient, and then know the optimum timing of oil filling, by comparing the sum of the slope values within respective time periods with a predetermined value. The method is further capable of determining the timing of oil filling even when the rotation speed of the ball screw changes. The method includes a step of signal acquisition, a step of converting signal, a step of defining and saving eigenvalues, a step of calculating eigenvalues, and a step of determining oil filling.

Abstract: A linear transmission device includes a shaft, a moving member movably provided on the shaft, and a lubrication unit provided at the moving member. The lubrication unit has a lubricant container and a block. The lubricant container has a storage space which communicates with the interior of the moving member via a lubricant dispensing opening. The block is provided in the storage space of the lubricant container and can be displaced by an inertial force generated by movement of the moving member so that, during its displacement, the block squeezes the lubricant in the storage space, thereby driving the lubricant into the interior of the moving member through the lubricant dispensing opening for lubrication.
