Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] see Figure 1~2 , the sleeve assembly of the present embodiment includes a sleeve body 11 and a mandrel 21, the middle part of the sleeve body 11 is provided with a through hole for the mandrel 21 to pass through, the inner wall of the through hole is provided with an annular graphite layer 12, and the annular graphite The layer 12 is provided with grooves 13 along the axial direction, the number of grooves 13 is 4-6, and the annular graphite layer 12 is provided with an annular passage 15 passing through the grooves 13 along the radial direction.

[0021] Graphite has the advantages of high strength, wear-resistant lubrication, good thermal shock resistance, and easy precision machining. It is an ideal inorganic non-metallic material. The sleeve assembly of the present invention, on the one hand, the annular graphite layer 12 has good wear-resistant lubricat...

Abstract

The invention discloses a sleeve assembly, which comprises a sleeve body and a core shaft; a through hole through which the core shaft can pass is formed in the middle of the sleeve body; an annular graphite layer is arranged on the inner wall of the through hole; and a groove is formed in the annular graphite layer along the axial direction. According to the sleeve assembly disclosed by the invention, one one hand, the annular graphite layer has the good wear-resistant, lubrication and strength properties and has the good lubrication effect, on the other hand, a lubricating agent/oil is added into the sleeve body and can be stored in the groove for a long time; when the sleeve body and the core shaft are used in a matched manner, the lubrication effect is further enhanced, so that the mutual abrasion is greatly reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of machine tool accessories, in particular to a sleeve assembly.
