Description

Technical Field

[0001] The utility model belongs to the technical field of linear guide rails and relates to an oil absorption and drip prevention structure of a roller guide rail. Background Art

[0002] The roller guide is configured as a combination of a concentric wheel and an eccentric wheel. The eccentric wheel can be manually adjusted for pre-tightening. In extreme application scenarios such as high and low temperatures, it can effectively eliminate problems such as excessive or insufficient pre-tightening force caused by thermal expansion and contraction. In applications such as food processing and high-clean rooms, the transmission structure requires that there is no oil dripping on the guide surface and even lubrication is not allowed. When the roller guide needs to be lubricated, oil dripping is inevitable, affecting hygiene and safety. There is a lack of corresponding oil absorption structure to absorb and collect excess lubricating oil.

[0003] In order to overcome the shortcomings of the existing technology, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses a high-speed roller linear guide [application number: 201721668324.8], which includes a guide body, an optical axis, a slider, and a concave-convex roller. The guide body has an upward-opening chute along its length. The optical axis is mounted on the two inner side walls of the guide body. The concave-convex roller is movably mounted in the chute. The concave-convex roller is located between the two optical axes and is slidably connected to the two optical axes. A cam mounting groove is formed on the top of the slider. An eccentric cam is mounted in the cam mounting groove. The eccentric cam has an eccentric shaft hole extending through it. A roller shaft passing through the bottom through hole of the slider is mounted between the eccentric shaft hole of the eccentric cam and the wheel shaft hole of the concave-convex roller. When the eccentric cam rotates, it can drive the concave-convex roller to move through the roller shaft, thereby adjusting the gap between the concave-convex roller and the optical axis. However, after lubrication, this solution is prone to dripping of excess lubricant. The solution still lacks a corresponding oil absorption structure, which has the disadvantage of affecting hygiene and safety. Utility Model Content
