End plastic cover and linear guide rail pair

Abstract

The invention discloses an end plastic cover and a linear guide rail pair. The end plastic cover is of a concave structure, wherein the concave structure specifically comprises a middle area and protruding areas on two sides, circulating channels are formed in the protruding areas on the two sides, a lubricating oil groove communicated with the circulating channel is formed on a side face, close to a sliding block body, of the end plastic cover and comprises a main lubricating oil groove and branch lubricating oil grooves, the main lubricating oil groove is located in the middle area of the end plastic cover, the two branch lubricating oil grooves are located in the protruding areas on the two sides respectively, and each branch lubricating oil groove is communicated with the circulating channel in the corresponding protruding area, an oil injection hole is further formed on the end plastic cover and communicated with the lubricating oil main groove. The end plastic cover is advantagedin that the lubricating oil is injected into the circulating channel through the oil injection hole, the lubricating oil can fully and stably lubricate a rolling element, the probability of temperature rising, abrasion and the like when the rolling element linearly moves on the guide rail is reduced, abrasion between the rolling element and the guide rail is reduced, use precision of the linear guide rail pair is improved, and the service life of the linear guide rail pair is prolonged.

Description

technical field [0001] The present application relates to the technical field of linear slide rails, in particular to end plastic covers and linear guide rail pairs. Background technique [0002] The linear guide rail pair consists of two parts: the guide rail and the slider. The slider includes the slider body, rolling elements, end plastic covers and other components to ensure the circular rolling of the rolling elements. When in use, the slider uses its internal steel balls as the medium Linear movement on the guide rail. [0003] However, in actual use, the linear motion of the linear slider on the guide rail with rolling elements as the medium will cause a certain temperature rise and wear, which will affect the accuracy and life of the linear guide pair. If there is less wear between the rolling elements and the guide rail , it needs to be regularly filled with lubricating oil for maintenance, which not only affects the continuous work of the linear guide pair, result...
