Leakage-proof lubricating grease for gear coupling and preparation method thereof

Abstract

The invention provides leakage-proof lubricating grease for a gear coupling and a preparation method thereof. The leakage-proof lubricating grease comprises the following components in percentage by mass: 95-99% of No.3 extreme pressure lithium-based grease, 0.6-2.5% of molybdenum disulfide, 0.3-1.5% of cerium oxide and 0.1-1% of a red pigment. The preparation method comprises the following steps: sequentially adding the No.3 extreme pressure lithium-based grease, molybdenum disulfide, cerium oxide and the red pigment, stirring for 1.5-3 hours at the temperature of 120 DEG C and the speed of 800-1000 r / min, and degassing for 15-30 minutes, so as to obtain the leakage-proof lubricating grease for a gear coupling. According to the leakage-proof lubricating grease for a gear coupling and the preparation method thereof, the leakage-proof lubricating grease has excellent extreme pressure anti-wear performance, high temperature resistance and adhesion performance, the phenomena of corrosion and leakage can be effectively eradicated, the operation safety of a gear coupling is greatly improved, meanwhile, the service life of the gear coupling is greatly prolonged, and the maintenance cost of the gear coupling is reduced; and the preparation method of the leakage-proof lubricating grease is simple to operate and easy to produce.

Description

technical field [0001] The present application relates to the technical field of lubricating oil, in particular to a gear coupling anti-leakage lubricating grease and a preparation method thereof. Background technique [0002] Toothed coupling is a kind of movable rigid coupling. It uses the meshing of internal and external gears to realize the transmission of torque and rotational motion between the two halves of the coupling. It is suitable for the transmission shaft system connecting two concentric shafts, and has the performance of compensating the relative displacement of the two shafts. Due to its compact structure, large load capacity, wide range of operating speeds, and reliable operation, toothed couplings are widely used in various machinery industries such as metallurgy, mining, lifting transportation, petroleum, and shipping. [0003] The gear coupling consists of an inner ring with the same number of teeth and a flange half coupling with an outer ring. It is a ...

Problems solved by technology

[0007] Through the analysis of the working characteristics and production requirements of the toothed coupling of the reducer, it is not the most effective way to replace the sealing ring of the toothed coupling. Usually, it is necessary to completely replace the sealing ring of the toothed coupling. The process is more complicated, and the workload of disassembling the coupling is relatively large. It is true that the maintenance cost is too huge to deal with the oil leakage of the coupling in this way. Due to the problem, the split seal ring was specially developed or the original seal ring was cut off and then bonded together, but these two methods are often difficult to guarantee the sealing quality, so simply replacing the seal ring is not only difficult but also has limited effect
