Abstract

The invention provides exposed gear grease, comprising the following components of 50-90 parts by weight of a base oil, 4-10 parts by weight of thickening agent, 1-3 parts by weight of an antioxidant, 1-5 parts by weight of an anti-wear reagent at extreme pressure, 1-5 parts by weight of a solid antiwear agent and 10-20 parts by weight of an adhesive agent. Besides, the invention also provides a preparation of the exposed gear grease. The exposed gear grease provided by the invention has the advantages of simple composition and relatively low cost. Besides, the exposed gear grease has relatively strong adhesive capacity, excellent lubricity, good oil-saving property and relatively strong extreme pressure antiwear property. Furthermore, the exposed gear grease can retain grease thickness in a relatively large temperature range, thereby facilitating usages for an operating staff.

Description

technical field [0001] The invention relates to a lubricating grease, in particular to an open gear lubricating grease and a preparation method thereof. Background technique [0002] Gear transmission mainly includes three types: open gear transmission, semi-open gear transmission and closed gear transmission. Among them, open gear transmission refers to a transmission mode in which there is no dust cover or casing installed outside the gear, so the gear is completely exposed to the outside. Because the open gear transmission has the advantages of flexible mechanical design, simple use, and low cost, it is widely used in extra-large rotating equipment, such as grinders, dryers, and mining electric shovels. [0003] Since the gears of the open gear transmission are completely exposed to the outside, on the one hand, when the gears are working, foreign debris is very easy to invade; on the other hand, due to the harsh working conditions of the gears, the gear teeth are very e...
