The invention discloses a special lubricating grease for low-speed motor bearings and a preparation method thereof, belonging to the technical field of lubricating grease for low-speed motor bearings. The main points of the technical solution of the present invention are: a special lubricating grease for low-speed motor bearings, which is prepared from the following raw materials in parts by weight: 60 parts of dodecyl hydroxystearic acid, 40 parts of stearic acid, 38 parts of lithium hydroxide, 3 parts of calcium hydroxide, 10 parts of azelaic acid, 10 parts of sebacic acid, 10 parts of dibenzyl disulfide T322 additive, 5 parts of T406 additive and 108 parts of base oil, and specifically disclose the special lubricating grease for low-speed motor bearings method of preparation. The low-speed motor bearing special lubricating grease of the present invention prolongs the service life of the low-speed motor bearing, reduces the starting load of the low-speed motor at the same time, ensures the long-term stable operation of the low-speed motor, improves the production efficiency of the enterprise, and reduces the production cost of the enterprise.
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...
