Embodiment Construction

[0024] Please see first figure 1 and figure 2 , The linear transmission device 10 of the first embodiment of the present invention includes a long shaft 20 , a moving body 30 , a plurality of balls 40 , and a lubricating unit 50 . In this embodiment, the linear transmission device 10 is a ball screw, so the long axis 20 is a screw shaft in this embodiment, and the moving body 30 is a nut.

[0025] The outer peripheral surface of the long shaft 20 has an external thread groove 22 .

[0026] The moving body 30 is sheathed on the major axis 20 and can move back and forth along the axial direction of the major axis 20 . The outer peripheral surface of the mobile body 30 has a fuel tank installation groove 32, and the inner peripheral surface of the mobile body 30 has an internal thread groove 34, and the internal thread groove 34 corresponds to the external thread groove 22 of the long axis 20, so that the internal thread groove of the mobile body 30 A load channel 12 is forme...

Abstract

A linear transmission device with a lubricating unit comprises a long shaft, a movable body movably arranged on the long shaft and the lubricating unit arranged on the movable body. The lubricating unit is provided with an oil tank and a mass block, the oil tank is provided with an oil storage space, and the oil storage space communicates with the interior of the movable body through an oil outlet; and the mass block is arranged in the oil storage space of the oil tank and can generate displacement through the inertia force generated when the movable body moves, and lubricating oil in the oil storage space can be extruded in the displacement process of the mass block, so that the lubricating oil is supplemented from an oil outlet to the interior of the movable body, and the lubricating effect is achieved.

Description

technical field [0001] The invention relates to a linear transmission device, in particular to a linear transmission device with a lubricating unit. Background technique [0002] Due to the excellent mechanical transmission efficiency of linear transmission devices (such as ball screws or linear slide rails), they have been widely used in various machines that require precise movement. However, if the linear transmission lacks timely lubrication under long-term use, it is easy to cause the friction between the moving body and the long axis to gradually increase and accelerate the wear of the linear transmission. [0003] As far as the related prior art is concerned, the Chinese Taiwan Publication No. 201015000 patent is to provide a storage space for lubricating oil in the nut, and then use the restoring force of the elastic element to pull the piston, so that the piston will lubricate during the displacement process. The oil is squeezed out between the screw shaft and the ...
