Abstract

The invention discloses a sweat gland type solid lubrication rod for a gauge surface, a preparation method thereof and a clamping device thereof. The sweat gland type solid lubrication rod comprises a casing and an inner core, wherein the inner core comprises the following components in parts by weight: 3-8 parts of lithium-based grease, 1-3 parts of graphite, 1-3 parts of kieselguhr, 0.5-1 part of an anti-wear reagent at extreme pressure and 0.5-1 part of silicone oil. According to the gauge surface solid lubrication rod having a casing-inner core composite structure, the preparation method thereof and the clamping device thereof disclosed by the invention, lubricating oil components are stored in a micro network structure of the solid lubrication rod to simulate the human body sweat gland principle in the case of friction heat-stress action, the oil components seep from the interior to be compounded with graphite and other layered solid lubricating materials so as to form excellent grease lubrication and attachment performance on the surface of a wheel track, and form a lubricating transfer film having excellent solid lubrication extreme pressure performance; and the brake of a locomotive can not be influenced by entry of a steel rail tread by mistake, no oil stain is formed, the oil coating stripping phenomenon of the steel rail is avoided, and meanwhile the sweat gland type solid lubrication rod has the performance of relatively low noise.

Description

technical field [0001] The invention relates to the field of industrial lubrication, in particular to a gauge surface sweat gland type solid lubricating stick used for lubricating wheel rims of railway locomotives, subways, urban rail vehicles and port machinery wheels, its preparation method and its clamping device. Background technique [0002] The wheel rims of railway locomotives, subways and other urban rail transit vehicles and port machinery are always in contact with the rails during operation, and the wheel rims and rails are worn, especially in the small radius curve section, which shortens the service life of the wheels and rails, and Screeching noises are produced. [0003] In order to overcome the above problems, at present, dry (solid) lubricants are used to replace grease lubrication for locomotive wheel rims at home and abroad. Dry lubricants are a new type of polymer composite lubricating material that replaces the principle of fluid lubrication with the pri...
