Abstract: With the same recipe and technological conditions, experimental research on fill factor about rubber compound of all-steel radial tire was conducted in four types of X(S)M-1.7L mixers: intermeshing rotor mixer, variable intermeshing clearance mixer, shearing rotor mixer and variable shearing clearance mixer. Based on the summary and analysis of experiments, the authors discussed the influence of fill factor on performance of internal mixers and physical and mechanical properties of the rubber compound. And the optimal values of fill factor of different types mixer were determined.

Abstract: The relationship of maximum power relative to rotor clearance, filling factor, rotor speed, ram piston pressure and cooling water temperature was studied for the VIC(Variable Intermeshing Clearance) mixer. The study result by single-factor experiment method showed that in certain extent, the larger the value of rotor clearance, filling factor, rotor speed, ram piston pressure, the larger the value of maximum power would be; the smaller the value of cooling water temperature, the larger the value of maximum power would be. And the study result by quadratic orthogonal regression combinational design gave the mathematical expressions of maximum power.

Abstract: Due to the technical factors such as analytical design and virtual prototyping, the simple but representative sliding bar was chosen in this paper and its mathematical model of working contour was established by using the analytic method. And then, the parameterized model and VRML file structural drawing of sliding bar were given by using double extrusion method. It was proved that the components of the tripod universal joint were formed easily by using the double extrusion method based on Extrusion nodes. In addition, the tripod universal joint assembly model was also accomplished by using Inline nodes and bottom-up assembling method.

Abstract: The effects of the lubricant properties on the lubricating performance of the tripod sliding universal joint were studied under thermal condition by numerical method. The obtained results show that increasing lubricant viscosity increases the film thickness whereas increasing viscosity-pressure coefficient or viscosity-temperature coefficient is just the reverse. The pressure hardly depends on the viscosity-pressure coefficient or viscosity-temperature coefficient, and a larger lubricant viscosity induces only a remarkable second pressure peak. Increasing lubricant viscosity or viscosity-pressure coefficient increases the temperature whereas the increasing viscosity-temperature coefficient reduces it.
