The second interaction sides of the top and intermediate coil modules are juxtaposed with each other in the accommodating space of the bottom coil module. An ironless motor includes a magnetic rail assembly and the aforesaid coil assembly.

Abstract: The present disclosure relates to a gripper device which comprises: a belt pulley driven by a power-driven motor; a belt and another belt pulley driven by the above belt pulley; a ball screw driven and rotated by the belt pulley; nut brackets driven to be shifted along two rigid guideways by two reverse threads at both sides of the ball screw, respectively; a plurality of steel balls, which are installed between a nut bracket and a rigid guideway and sustain more stresses when a workpiece is clamped between two upper slide on the nut brackets.

Abstract: A circulator structure includes a main body, a Y-like groove and two return channels. The main body has a first side surface, a second side surface and a through hole. The Y-like groove includes a first oil-guiding groove, a second oil-guiding groove and an oil distribution groove. The first oil-guiding groove and the second oil-guiding groove are located at two opposite sides of the through hole, and the oil distribution groove is located below the through hole. A lower guiding end of the first oil-guiding groove and a lower guiding end of the second oil-guiding groove are respectively connected to the oil distribution groove. The oil distribution groove has an upper end distribution opening connected to the through hole and a lower end distribution opening. The return channels are respectively located on two opposite sides of the first side surface and are connected to the lower end distribution opening.

Abstract: A lubricating tube includes an inner surrounding surface that has a non-circular cross-section, angularly spaced-apart inner lubricant-storing recesses, and guide surface portions each of which is interconnected between two adjacent ones of the inner lubricant-storing recesses. The inner lubricant-storing recesses and the guide surface portions constitute the inner surrounding surface and cooperatively define a roller passage hole. The inner lubricant-storing recesses are indented from the guide surface portions toward the outer surrounding surface. A slide rail device having the lubricating tube is also disclosed.

Abstract: A slide apparatus includes a track body, at least one primary module, and a slider provided therein with a secondary module. The track body defines a recessed space therein, and the primary module is installed in the recessed space. The slider is slidably mounted on the track body and has a housing located in the recessed pace of the track body. The housing is provided with at least one channel in which the secondary module is located. The channel of the housing, which opens out at a bottom opening facing to a bottom of the track body, serves as a jig to facilitate the secondary module formed integrally with the housing of the slider. The secondary module works with the primary module to constitute a linear motor, which enables the slider to move linearly along the track body.
