| Abstract: | With large amount of test data, the influences of materials, geometrical dimensions, sealing and friction characteristics, and end face temperature rise of rotary sealing ring in locking mechanism of power-shift transmission of hydrodynamic drive dozer to the performance are described in details. Concrete method to solve sealing leakage is suggested. The kinetic state of rotary sealing ring is analyzed. Equations of temperature rise vs. open gap are derived. |
