The invention discloses a differential gear positioning structure of a double-turbine hydraulic torque converter. The differential gear positioning structure comprises a pump wheel, a differential gear, a guide wheel base, a first bearing, a second bearing and a guide wheel; outer rings of the first bearing and the second bearing are respectively mounted in step holes of the differential gear; the step holes of the differential gear include a first step surface, a second step surface and a third step surface; the left side of the outer ring of the first bearing is positioned on the second step surface; the right side of the outer ring of the second bearing is positioned on the first step surface; and when the first bearing and the second bearing are assembled in place, the left side of the outer ring of the first bearing and the right side of the outer ring of the second bearing form a separation structure. The differential gear positioning structure has the following advantages: the differential gear is provided with steps, so that separate assembly of two bearings is realize; and in the assembly process, the positioning surfaces are provided and reliable and controllable, so that the problem of bad bearing assembly of the differential gear can be effectively solved, and the problem of damage of the bearing caused by axial movement is solved.
Description
technical field [0001] The invention relates to a twin-turbine hydraulic torque converter mainly used in construction machinery, in particular to a transfer gear positioning mechanism of the twin-turbine hydraulic torque converter. Background technique [0002] In construction machinery, the hydraulic torque converter plays the role of increasing the output torque, and its main components include cover wheel, pump wheel, turbine assembly and guide wheel. [0003] The working principle of the hydraulic torque converter is: the torque converter is filled with oil, the engine drives the pump wheel to rotate to convert the mechanical energy into the kinetic energy of the oil in the flow channel of the pump wheel, and the oil rushes along the direction of the pump wheel blades under the action of centrifugal force. The blades of the turbine assembly rotate the turbine assembly, and the oil then rushes to the stationary vanes of the stator. According to the principle of action fo...
