Development Of Low-noise Titanium Complex Grease

With the rapid development of modern industry, high qualities of greases are stringently demanded by many factories.Grease become more and more important in reducing the noise of bearing. By changing the bearing grease to reduce the noise of bearing is a simple and economical method. Ti-complex grease is a new multi-effect grease, has very excellent performance and wide application prospects. So it is necessary to develop a kind of Titanium complex grease which can reduce the noise of bearing.The main subject of this paper is about the following aspects. Research the formulas of Ti-complex grease, include base oil type, the ratio of base oil, base oil viscosity, base oil way of adding, different ratio between materials, different proportion of different nano-particles. The impact of test results analyzed according to rules drawn, improved Ti-complex grease formula, so that the Ti-complex grease has good low-noise performance; research on the proportion of different materials using orthogonal test method, As a proportion of the factors exists between the amount of acid and titanate, so titanate set at the level of activity, and determined the titanate level of activity by 0.618 method. Research the refining temperature, cooling and grinding the composite frequency of preparation of titanium-based grease noise performance, find out a grease can make the composite titanium low-noise performance with good preparation. Grease noise testing using the speed-based testing methods, the instruments for the production of Hangzhou Bearing Test Centre Ltd's BVT-1 bearing vibration tester. The friction performance of Grease tested by four-ball method, and use the four-ball test machine. Test the low-noise grease noise performance, friction properties and test the physical and chemical properties of prepared Ti-complex grease, and compared with low noise grease on the market.Through research projects, summed up the law of base oil, additive, the ratio of acid and titanate and refining temperature and cooling method how to effect the low-noise performance of Ti-complex grease and to explore the correlation between the performance of the grease and the noise. This research paper provide guidance on preparation of low-noise Ti-complex grease, and on explore the correlation between the noise properties of grease and other properties of grease.
