Description

Linear slide with lubrication

The invention relates to a linear slide rail, in particular to a linear slide rail with a lubricating device.

In the precision transmission device, a linear slide rail and a ball screw are common, and the linear slide rail and the ball screw are displaced by a moving member with respect to a long axis, and the lubrication effect between the moving member and the long shaft is improved. A lubricating device is disposed between the moving member and the long shaft. As shown in the fifth figure, a storage tank (12) is mounted on the long shaft (11) of the linear slide rail (10), and the oil storage tank (12) The lubricating oil is stored therein, and a moving member (13) slidably disposed on the long axis (11) and the sump (12) are provided with an smear structure (14), the smear structure (14) and the oil storage tank ( 12) A connector (15) having an oil guiding member (151) is further disposed, and the lubricating oil in the oil storage tank (12) is adsorbed by the oil guiding member (151) of the connector (15) and transmitted to the painting structure. (14) Lubricate the rolling groove of the long shaft (11); however, the oil guiding member (151) of the linear sliding rail (10) is made of wool felt, and is caused by capillary phenomenon when conveying lubricating oil. As a result, as long as the lubricating oil is stored in the oil storage tank (12), the oil guiding member (151) continuously conducts the oil guiding, so that the oil is continuously guided regardless of whether the moving member (13) is moved or not. Action, and produces oil spills occur.

In view of the above problems, the main object of the present invention is to develop a lubricating device capable of controlling the release of oil without increasing the length of the slider module of the linear slide.

In order to achieve the above object, the present invention is a linear slide rail with a lubricating device, comprising: a long shaft extending in a direction to a long strip shape, defining the direction as an axial direction, and the axial direction of the long axis a sliding groove is disposed on each side; a slider module is slidably disposed on the long axis, and includes a slider and two reflow elements, the slider is provided with a rolling groove relative to the rolling groove, and the rolling groove and the rolling groove are Forming a load path, the slider is further provided with a plurality of return holes extending through the end faces of the axial direction, and the two reflow elements are respectively disposed on the two end faces of the slider, and the two reflow elements are respectively provided with a plurality of two The return path is connected to the load path and the return hole respectively, and the load path, the return hole and the return flow path form a circulation path, and the circulation path provides a plurality of rolling elements; wherein at least one of the return elements has an oil reservoir and a fixed through hole, the oil storage tank, the return passage and the fixed through hole communicate with each other, the oil storage tank is filled with lubricating oil; a coating member is disposed on the fixed through hole; and a transmitting member covers the application member, Hands-based absorbent member and then transmitted to the lubricant applicator member, when the rolling element return path passes through the contact line of the applicator member.

Preferably, the applicator member and the transfer member are made of wool felt, and the density of the felt of the applicator member and the transfer member is different.

Preferably, the reflow element is composed of a body and a cover plate, the body has the oil reservoir, the fixed through hole and a second half flow channel, the cover plate has a first half opposite to the second half flow channel The flow path, the first half flow path and the second half flow path system constitute the return flow path.

Preferably, the profile of the applicator corresponds to the fixed through hole.

Preferably, the reflow element has a positioning cover which is disposed on the oil reservoir and presses and fixes the transmission member.

The invention covers the applicator by the transmitting member, so that the applicator does not directly absorb the lubricating oil, thereby reducing the amount of the lubricating oil released, and since the applicator must contact the rolling body to release the oil, when When the rolling element does not happen to be in contact with the application member, the application member will not release the lubricating oil, and since the application weight of the application member and the transmission member is different, it is generally recommended to apply The density of the smear member is greater than the transmission member (or vice versa), so that the oil release rate of the smear member can be controlled, and the difference in density of the wool felt can be adjusted according to different industries, so the invention can improve the versatility of the lubrication device; Since the oil storage space is a space that is idle by the body of the reflow element, it is not necessary to additionally add a fuel tank to store the lubricating oil, so that the length of the slider module does not change.
