Special lubricating oil for dobby

Abstract

The invention discloses special lubricating oil for a dobby. The special lubricating oil comprises the following components in parts by weight: 85-98 parts of base oil, 0.3-2 parts of antioxidant, 0.5-5 parts of anti-wear reagent at extreme pressure, 1-5 parts of friction improver, 0.03-0.3 part of metal deactivator, 0.05-2 parts of antirust agent, 0.001-0.05 part of anti-foaming agent and 0-0.3 part of demulsifying agent. The special lubricating oil has the beneficial effect that the lubricating oil is prepared by using selected mineral oil and synthetic oil as the base oil and using the anti-wear reagent at extreme pressure, the friction improver, the antioxidant, the anti-foaming agent and the demulsifying agent as raw materials in matching; the lubricating oil is excellent in extreme pressure, abrasion resistance, oxidation resistance, foaming resistance, emulsifying resistance and extreme low in friction coefficient, is a new-generation lead-free and chlorine-free environment-friendly dobby lubricating oil, and is used for lubricating the dobby; the lubricating oil is capable of effectively reducing the temperature rise, reducing abrasion, and prolonging the oil change period.

Description

technical field [0001] The invention relates to a special lubricating oil for a dobby. Background technique [0002] The dobby, also known as the dobby opening mechanism, is one of the important components of the loom. The function of the dobby is to control the lifting of the heald frames in order to make the warp yarns form a shed so that the weft yarns can pass through, thereby completing the weaving of warp yarns and weft yarns. The main friction pair of this kind of machinery is mainly sliding friction, supplemented by rolling friction; the lubrication method mostly adopts oil bath lubrication, and some use forced circulation lubrication; the speed is medium, and the torque is also low. Its power input is transmitted by a pair of gears, while the output is output by multiple cams through sliding friction. Due to the small size and compact structure of the dobby, the types of friction pairs are different, and the heat generated during work is relatively large, so the l...
