Definition of low noise grease

Low noise grease is a grease that has been adequately purified, in which there are no or only very few impurities. Large impurity particles into the bearing or rotating parts of the machine and equipment will cause noise. For the overall cost of the application of low noise fat, overseas think: for many industrial motor production with grease: Assuming that the thickener, base oil price viscosity and other characteristics of grease can be accepted, the value of the service life of motor bearings resulting from the application of low noise grease will exceed the cost increase provided by the high price of low noise grease. This type of grease is originally manufactured for precision processing of the lifting platform, if there are impurities into the bearing or bearing parts of this facility, it is likely to lead to the destruction of this part.

There are several ways of accurately measuring the quality of grease overseas. The cleanliness of the grease can be indicated by the noise caused by bearing testing; It can also be smeared on a tablet to look for contaminants in it. Testing for contaminants in raw materials and final products is also necessary, otherwise it is unlikely to be possible to know the composition of solid contaminants in final products.First of all, there are a large number of machines and equipment overseas daily application of low noise fat: the volume motor used in household appliances, some of the driving components of electronic computers and some of the small motors of other machinery and equipment benefit from low noise fat or high pure fat.

Times, can according to eliminate impurity particles or contaminants to remove bearing noise, these impurities or contaminants force bearing abrasion or subjected to coupling impacts caused, if impurity elements to a certain level, under the condition of the same situation, affect all the normal operation of fitness components, make its posture is not harmonious. This may reduce the service life of bearings and motor reliability. Such things are similar to the hydraulic transmission system software, particles into the work area, will destroy the friction pair, reduce the service life of the work.
