One-way bearing characteristics and strength of purpose and grease measurement

The main features of one-way bearing Description: One-way bearings used powder metallurgy forming and sintering metal powders (or metal powder and metal powder mixture) technology made products. In the study the characteristics of powder characteristics and process changes based on the corresponding technical process used to change the shape of powder, performance and their organizational structure and adapt to the different needs of bearing products.
Physical one-way bearings GCr15 bearing steel, heat treated hardness of HRC61-65, bearing small size and high carrying capacity, there is enough storage space for grease, may have come a long lubrication intervals. <BR> PM One-way bearing and physical one-way shaft bearing can be driven to full power when the "locked" to avoid the traditional one-way bearing outer ring pressing "lock" the problem of inadequate performance.
One-way bearing main purposes: textile machinery, printing machinery, automobile, household appliances, Detector.
Grease is the ultimate strength of the sample began to flow induced shear stress, also known as yield stress or ultimate strength of stress, referred to as ultimate strength. Ultimate strength of the grease that letters τ, in units of Pa.
Grease ultimate strength measurement methods: determination of ultimate strength of a standard grease is SH / T 0323-92, measured at the test temperature grease in the plastic threaded tube displacement occurred when the maximum pressure, and replaced with strength limits.
Grease ultimate strength depends largely on the type of thickening agent being in the amount of grease, containing soap volume increased, the ultimate strength also increases. Grease ultimate strength and temperature. The higher the temperature, the smaller the ultimate strength of resin; temperature decreases, then the ultimate strength of resin increases. According to the intensity of high temperature limit the application of grease can be a rough indication of the temperature limit. Actual use in grease, the grease strength limit the scope of between about 100-300Pa. In general, the mobility of grease is often the strength of high temperature limit is expected to ease to flow
And similar to low temperature viscosity values can be expected if the normal flow.
