Abstract

The invention discloses special lubricating grease for a low-speed motor bearing and a preparation method of the special lubricating grease, belonging to the technical field of special lubricating grease for low-speed motor bearings. The technical scheme has the key points as follows: the special lubricating grease for the low-speed motor bearing is prepared from the following raw materials in parts by weight: 60 parts of dodecahydroxyl stearic acid, 40 parts of stearic acid, 38 parts of lithium hydrate, 3 parts of calcium hydroxide, 10 parts of azelaic acid, 10 parts of sebacic acid, 10 parts of benzyl disulfide T322 additives, 5 parts of T406 additives and 108 parts of base oil. The invention concretely discloses the preparation method of the special lubricating grease for the low-speed motor bearing. By using the special lubricating grease for the low-speed motor bearing, disclosed by the invention, the service life of the low-speed motor bearing is prolonged, meanwhile, the starting load of a low-speed motor is reduced, the low-speed motor can stably work for a long term, the production efficiency of an enterprise is increased, and the production cost of the enterprise is reduced.

Description

technical field [0001] The invention belongs to the technical field of special lubricating grease for motor bearings, and in particular relates to a special lubricating grease for low-speed motor bearings and a preparation method thereof. Background technique [0002] Motor is an essential tool in daily life, and also an indispensable equipment for every enterprise production. There are many types of motors, and their working environment and working characteristics are different, so each motor has its own characteristics. For example, some motors have a small load but require precision and no vibration; some motors have a large load, which requires the motor bearing to have a high ability to withstand extreme pressure; Bearings are resistant to acids and bases, etc. The quality of each motor is not only produced strictly according to the standard in the manufacturing process, but also an important aspect is whether the motor bearing grease is used correctly. Low-load high...
