Embodiment 1

[0013] The main structure of the wear strip device involved in this embodiment includes a wear strip body 1, an installation hole 2, a blind hole 3, a glue layer 4 and a graphite column 5; the wear strip body 1 is provided with four through installation holes 2, and the installation holes 2. It is composed of upper and lower through-holes with circular frustum-shaped structures. The diameter of the upper circular platform is not equal to the diameter of the lower circular platform. The wear strip body 1 is also provided with 30 blind holes 3 with circular structures. The blind holes 3 Divided into upper and lower rows, arranged in parallel with each other, the blind hole 3 is provided with a glue layer 4 and a graphite column 5, and the glue layer 4 and the graphite column 5 are adhesively connected.

[0014] The mounting holes 2 involved in this embodiment are used for connecting with blocked components.

Abstract

The invention belongs to the technical field of rail transit equipment, and particularly relates to a wearing strip device, the main structure of which comprises a wearing strip body, blind holes, glue layers and graphite columns, the wearing strip body is provided with a plurality of non-through blind holes, and the blind holes are internally provided with the glue layers and the graphite columns. The wearing strip body made of nylon is combined with the graphite columns made of graphite, so that the wearing strip device has a self-lubricating function, has toughness and abrasion resistance of a nylon base body and excellent lubricating and antifriction performance of graphite, has the bearing capacity, breaks through the self-lubricating limit of nylon, the friction coefficient between the blocked parts and the friction noise decibel between the blocked parts are greatly reduced, the use environment of the blocked parts is improved, and the service life is prolonged; the manufacturing process is simple, the use environment is friendly, the service life of the blocked part is prolonged, the replacement frequency is reduced, the maintenance cost is saved, and the wearing degree isreduced.

Description

Technical field: [0001] The invention belongs to the technical field of rail transportation equipment, and in particular relates to a wear strip device. By optimizing the structure of the wear strip, the coefficient of friction between two objects blocked by the wear strip is reduced, and the service life of the wear strip is prolonged. Background technique: [0002] The through-passage is an internal passage for passengers to walk freely from one compartment of a rail transit vehicle to another and to make passengers feel safe and comfortable. In the multiple structures of the through-passage, wear strips need to be used to prevent direct contact between two metal parts , to reduce noise and prolong the service life of components. Chinese patent 201711423401.8 discloses a wear assembly for rail vehicle passages, including: wear strips, the top of which is suitable for fixed connection with the bellows assembly of the passage; wear plates, the bottom of which wear plates It...
